Abstract
Description
[0001] FOOD EMULSION COMPOSITIONS WITH LENTIL PROTEINS AND CEREAL BRAN
[0002] TECHNICAL FIELD
[0003] The present invention relates generally to the field of emulsions comprising plant ingredients, incl. plant proteins. For example, the present invention relates to food emulsion compositions comprising lentil protein ingredient and cereal bran and method for preparing such food emulsion compositions.
[0004] BACKGROUND OF THE INVENTION
[0005] Food emulsions, in particular dairy emulsions such as milk or creamer, are widely consumed. They can be liquid or in powder form.
[0006] Some consumers wish to reduce or even stop their consumption of milk and ingredients derived from milk. For example, this can be for reasons of lactose intolerance, dairy allergies, or environmental sustainability.
[0007] To meet this growing demand, there is a need to provide food emulsions, in particular dairy emulsion analogues, prepared with lower amount of or without milk or ingredients derived from milk. This can be achieved by replacing milk and ingredients derived from milk by plant-based ingredients.
[0008] There were attempts to prepare food emulsions, such as creamer, with plant-based ingredients. However, these emulsions are generally not satisfactory.
[0009] First, these emulsions are generally prepared with soy-based ingredients, such as soy proteins, as a partial or total substitute to milk and / or milk ingredients. However, some consumers reduce or avoid the consumption of products comprising soy-based ingredients for health, nutritional and sustainability reasons. For example, some consumers suffer from soy allergies.
[0010] In addition, these emulsions may be prepared with plant protein isolates, which are highly refined ingredients. However, plant protein isolates are not advantageous for several reasons. First, they require high energy processing to be produced, they are viewed as highly refined ingredients, and they have higher cost. Second, they are generally produced through process including precipitation steps. The precipitation steps generally result in proteins in an aggregated state that may negatively impact protein functionality, in particular when used in food and beverage applications, including in food emulsion applications. For example, the aggregated state of the proteins tends to change_their emulsion stabilization properties, worsening the final emulsion structure.
[0011] Less refined ingredients, such as flour or plant protein concentrate, tend to be avoided as they could be difficult to process. Indeed, they comprise compounds, e.g. fibers, that could be unstable, or could generate too high viscosity or unsatisfactory texture over emulsion manufacturing process. To overcome processing challenges for less refined ingredients, they are generally enzymatically treated to hydrolyse relevant compounds, such as fibers or proteins. However, enzymatic treatments are generally difficult to handle at an industrial scale and can be expensive. In addition, plant protein hydrolysis improves plant protein solubility but at the same time tends to decrease surface active properties of the plant proteins. As a result, hydrolysed plant proteins have generally lower emulsion stabilization properties compared to non-hydrolysed plant proteins.
[0012] Food emulsions based on plant-based ingredients generally have limited stability properties and exhibit important fat droplet size. Moreover, the plant proteins of such food emulsions tend to flocculate when added in beverages, with acidic pH and / or with important hardness, such as coffee. This protein flocculation negatively impacts the sensory properties of the food emulsions. To overcome these stability challenges, buffer and / or stabilizing salts may be added into food emulsion compositions. However, buffer and / or stabilizing salts may be perceived as non-natural by some consumers and may be misaligned with clean label trend / approach.
[0013] Moreover, food emulsions based on plant-based ingredients may have unpleasant sensory properties. In particular, they may have texture with limited smoothness, and they may exhibit unpleasant dry mouthfeel.
[0014] In addition, food emulsions in powder form, e.g. powdered milk or powdered creamer, appear as an advantageous and convenient format to food producers and consumers. Indeed, powders have extended shelf life and are generally easy to handle.
[0015] However, the food emulsions in powder form prepared with plant-based ingredients on the market may have limited reconstitution properties in cold and hot liquid and may form emulsions with limited stability and with important fat droplet size upon reconstitution.
[0016] In particular, the powdered food emulsions prepared with plant-based ingredients on the market are not suitable for cold applications. In particular, upon reconstitution in cold liquids, they generally exhibit low cold reconstitution properties. This results in the presence of lumps formed of insolubilized powder. These lumps result in emulsions with unpleasant visual and sensory properties. Moreover, as the powdered emulsion is not fully reconstituted, the intake of micro- and macro- nutrients may be adversely impacted. These cold reconstitution challenges are even higher for food emulsions comprising significant amount of fat, such as plant-based creamers.
[0017] It would therefore be desirable to provide food emulsions in liquid or powder form, preferably plant-based creamer analogues in liquid or powder form, prepared with plantbased ingredients having good emulsion stability properties, in particular emulsions with fat droplets as small as possible. Preferably, it would also be desirable to provide powdered food emulsions, preferably powdered plant-based creamer analogues having good reconstitution properties, particularly when reconstituted in hot liquids and / or cold liquids.
[0018] Preferably, it would also be desirable to provide food emulsions in liquid in powder or form, preferably creamer analogues in liquid or powder form with good sensory properties.
[0019] Preferably, it would also be desirable to provide food emulsions in liquid in powder or form, preferably creamer analogues in liquid or powder form, that retains the abovementioned good sensory properties, emulsion stability properties and reconstitution properties in the absence of any buffer and / or stabilizing salts, and / or added emulsifiers such as lecithin.
[0020] Preferably, It would also be desirable to provide food emulsions in liquid or powder form, preferably plant-based creamer analogues in liquid or powder form, that have good stability when added in beverages with acidic pH and / or with important hardness, such as coffee.
[0021] Preferably, it would also be desirable that the food emulsions in liquid or powder form, preferably plant-based creamer analogues in liquid or powder, retain good stability when added in beverages with acidic pH and / or with important hardness (e.g. coffee) while being free from any buffer and / or stabilizing salts.
[0022] It would also be desirable that the plant-based ingredients, in particular plant-based protein ingredients are minimally refined ingredients such as plant protein concentrate or flour.
[0023] Preferably, It would also be desirable that the plant-based ingredients, in particular plant-based protein ingredients are not hydrolysed, in particular via enzymatic hydrolysis. Preferably, It would also be desirable that the proteins of the plant-based protein ingredients are not hydrolysed, in particular via enzymatic hydrolysis. Preferably, it would also be desirable that the food emulsions in liquid or powder form, preferably plant-based creamer analogues in liquid or powder form, that are free from soy.
[0024] Any reference to prior art documents in this specification is not to be considered an admission that such prior art is widely known or forms part of the common general knowledge in the field.
[0025] SUMMARY OF THE INVENTION
[0026] The object of the present invention is to improve the state of the art, and in particular to provide a composition and a process that overcome the problems of the prior art and addresses the needs described above, or at least to provide a useful alternative.
[0027] The inventors were surprised to see that the object of the present invention could be achieved by the subject matter of the independent claims. The dependent claims further develop the idea of the present invention.
[0028] Accordingly, a first aspect of the invention proposes a food emulsion composition which comprises at least one fat ingredient, at least one plant protein ingredient and at least one cereal bran, wherein the plant protein ingredient is selected from the list consisting of plant protein concentrate, plant flour or a mixture thereof.
[0029] A second aspect of the invention proposes a method for preparing a food emulsion composition, the method comprises the steps of: dispersing at least one plant protein ingredient and at least one cereal bran in an aqueous liquid to form a plant dispersion, wherein the plant protein ingredient is selected from the list consisting of plant protein concentrate, plant flour or a mixture thereof, adding a fat ingredient, and optionally added carbohydrate in the plant dispersion to form a food pre-emulsion, homogenizing the food pre-emulsion to obtain a food emulsion, heat treating the food emulsion to obtain a food emulsion composition, optionally, drying the food emulsion composition to form a powdered food emulsion composition.
[0030] It has been discovered that the use of lentil protein ingredients which are minimally refined, such as lentil protein concentrate or flour, in combination with cereal bran provides food emulsion compositions with improved properties, including in the absence of any .added emulsifiers and / or any buffer and / or stabilizing salts. Especially, the obtained food emulsion compositions have good emulsion stability properties. In particular, they exhibit fat droplets as small as possible. This low fat droplet size contributes to good emulsion stability and limits destabilization phenomenon, such as creaming, during processing / manufacturing of the powdered food emulsion compositions. In addition, such food emulsion, in particular in powder, may also exhibit improved reconstitution in cold and hot liquids. They may also exhibit improved stability in hard and / or acidic beverages, such as coffee. Finally, they may also exhibit good sensory properties.
[0031] These and other aspects, features and advantages of the invention will become more apparent to those skilled in the art from the detailed description of embodiments of the invention, in connection with the attached drawings.

[0101] In an embodiment, the plant protein ingredient is not hydrolysed, in particular enzymatically hydrolysed. In other words, none of the nutrients of the plant protein ingredient, such as proteins, carbohydrates, fibers, fat, are hydrolyzed, in particular enzymatically hydrolyzed.

Preferably, it also allows the provision food emulsion composition with good stability in acidic and / or hard beverages, such as coffee, without the need to use hydrolysis and / or enzymatic treatment.
[0104] The food emulsion composition may comprise at least one cereal bran. The cereal bran may be bran selected from the group consisting of millet bran, rice bran, rye bran, barley bran, oat bran, wheat bran, spelt bran, and mixtures thereof. Preferably, the cereal bran is oat bran.
[0105] The cereal bran is pure cereal bran. In other words, the cereal bran is provided as an ingredient consisting of cereal bran. In particular, the cereal bran is free from the germ and endosperm from the cereal it originates from. Accordingly, food emulsion composition is free from the germ and endosperm derived from the cereal that the cereal bran originates from. Preferably, the food emulsion composition is free from germ and endosperm derived from cereals.
[0106] Whole cereal grains (i.e. grains with germ, endosperm and bran) are avoided because they tend to generate undesirable excessive viscosity during processing due to significant presence starch. They may require hydrolysis, for example with enzymes, to control viscosity built up during processing. However, hydrolysis, in particular enzymatic hydrolysis requires the use of exogenous ingredients (i.e. enzymes), impacts the nutrient composition end properties of the food emulsion composition and is intricate to implement at industrial scale.
[0107] It has been shown that the invention involving the use of plant protein ingredient, in particular lentil protein ingredient and cereal bran (and not whole cereal grain) allows the provision food emulsion composition with good emulsion stability (incl. small fat droplet size), good sensory properties and / or good reconstitution properties, in particular enhanced hot and / or cold reconstitution properties (for powder form) without the need to use hydrolysis and / or enzymatic treatment.

[0116] In an embodiment, the food emulsion composition may comprise a weight ratio of plant protein ingredient to oat bran from 4 to 0.25.
[0117] It has been shown that the use of plant proteins in combination of oat bran provides food emulsion compositions with good stability properties. First, the food emulsion compositions exhibit good emulsion stability in presence of plant proteins and oat bran. For example, the emulsions obtained with plant proteins and oat bran exhibit fat droplet with very small size (e.g. below lpm). This small fat droplet size contributes to the emulsion stability. Second, the food emulsion compositions preferably also have good stability when added in beverages with acidic pH and / or with important hardness, such as coffee. Indeed, these compositions do not flocculate when added in such beverages.
[0118] Moreover, the use of plant proteins in combination of oat bran preferably also provides food emulsion compositions with good sensory properties, incl. with smooth texture and limited dry mouthfeel.
[0119] Also, the combination of plant proteins and oat bran preferably also provides good reconstitution properties, including in hot and cold liquids, to food emulsion compositions in powder form.
[0120] It has been shown that these improved properties can be achieved even with the use of less refined lentil protein ingredients, such as plant protein concentrate or flour and in presence of significant amount of fat, e.g. for creamer applications.
[0121] In an embodiment, the pH of the food emulsion composition is greater than 6. Preferably, the pH of the food emulsion composition is of 6 to 9.

The term "added emulsifier" excludes the lentil protein ingredient, the fat ingredient, the buffer and / or stabilizing salt, the added carbohydrate ingredient, the milk, the plant-based milk analogue, the cream and the plant-based cream analogue. In other words, the added emulsifier is different from the lentil protein ingredient, the fat ingredient, the buffer and / or stabilizing salt, and / or the added carbohydrate ingredient. Examples of added emulsifier include mono- and diglycerides, lecithin, sodium stearoyl-2-lactylate, succinic acid esters of monoglycerides, diacetyl tartaric acid esters of mono- and diglycerides and combination thereof.

The sole combination of the plant protein ingredient and cereal bran is effective at providing food emulsion compositions that do not flocculate when added in beverages with acidic pH (e.g. below pH 5) and / or with important hardness (e.g. up to 400 ppm CaCCh), such as coffee. Hence, good stability properties in such beverages may be achieved without using any buffer and / or stabilizing salts.

This low viscosity for the plant dispersion facilitates processability, including pumping, flowing and drying (if any). In particular, if the viscosity is too high, this may block the pipes and also may prevent drying to form a powder, if any. The plant protein ingredient is selected from the list consisting of plant protein concentrate, plant flour or a mixture thereof.

[0156] In some embodiment, the food emulsion composition is liquid or semi-liquid. In particular, the food emulsion retains liquid or semi liquid consistency after the homogenization step. In a preferred embodiment, the food emulsion composition has a viscosity of 50 to 800, preferably 50 to 500, more preferably 50 to 300, even more preferably 50 to 200 mPa.s when measured at a shear rate 300s1and at a temperature 65°C, with a viscosimeter, in particular MCR502 (Anton Paar) equipped with cylinder cup CC27.

[0159] Gelation and / or coagulation and / or extrusion of plant proteins and / or cereal bran are not desirable as they may impact emulsion stabilization properties of plant proteins together with cereal bran.

Oat bran and non-hydrolyzed lentil protein concentrate (54.7wt.% lentil proteins) or non-hydrolyzed lentil flour (25.6wt.% lentil proteins) was added and dispersed in the water during 20 min under shear with the Ystral X50 / 10 to obtain a plant dispersion. The Fat blend PO:CNO-70:30and glucose syrup were added to the plant dispersion and mixed with the Ystral at high shear for 5 min to obtain a food pre-emulsion. The food pre-emulsion was heated at 110°C for 15 seconds through heat exchangers and went then through the homogenizer of the APV-HTST at 230 / 50 bars to form the invention liquid lentil-based creamer analogues Al and Bl. Finally, the invention liquid lentil-based creamer analogues Al and Bl were dried with a spray dryer NIRO SD6.3N to form the invention powdered lentil-based creamer analogues Al or Bl.
[0178] The recipe of the invention liquid lentil-based creameranalogues Al and Bl (i.e. before spray drying) is provided in table 1.
[0179] Table 1
[0180] The recipe of the invention powdered lentil-based creamer analogues Al and Bl (i.e. after spray drying) is provided in table 2.
[0181] Table 2
[0182] Example 3: Reference powdered lentil-based creamer analogues without oat bran
[0183] Four reference lentil-based creamer analogues free from dairy ingredients were prepared without buffer salts, without lecithin as emulsifier and without oat bran:
[0184] -reference liquid lentil-based creamer analogue Ref.Al prepared with lentil protein concentrate but without oat bran,
[0185] -reference powdered lentil-based creamer analogue Ref.Al prepared with lentil protein concentrate but without oat bran, -reference liquid lentil-based creamer analogue Ref.Bl prepared with lentil flour but without oat bran,
[0186] -reference powdered lentil-based creamer analogue Ref.Bl prepared with lentil flour but without oat bran.
[0187] The reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl or reference powdered lentil-based creamer analogues Ref.Al and Ref.Bl were prepared with the process as follows but with some differences.
[0188] The difference between creamer analogues Ref.Al and Ref.Bl is that creamer analogues (liquid or powder form) Ref.Al were prepared with lentil protein concentrate while the creamer analogues Ref.Bl (liquid or powder form) were prepared with lentil flour.
[0189] The difference between liquid or powdered creamer analogues is that the process for preparing liquid creamer analogues does not involve a final spray drying step while the process for preparing powdered creamer analogues involves a final spray drying.
[0190] Process:
[0191] Water was added in a tank and heated to 65°C. Non-hydrolyzed lentil protein concentrate (54.7wt.% lentil proteins) or non-hydrolyzed lentil flour (25.6wt.% lentil proteins) was added and dispersed in the water during 20 min under shear with the Ystral X50 / 10 to obtain a plant dispersion. The Fat blend PO:CNO-70:30 and glucose syrup were added to the plant dispersion and mixed with the Ystral at high shear for 5 min to obtain a food preemulsion. The food pre-emulsion was heated at 110°C for 15 seconds through heat exchangers and went then through the homogenizer of the APV-HTST at 230 / 50 bars to form the reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl. Finally, the reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl were dried with a spray dryer NIRO SD6.3N to form respectively the reference powdered lentil-based creamer analogues Ref.Al or Ref.Bl.

[0194] Ref.Bl (i.e. obtained after spray drying) is provided in table 4.
[0195] Table 4 Example 4: Reference powdered oat-bran based creamer analogue without lentil proteins
[0196] Four reference oat bran-based creamer analogues free from dairy ingredients and free from lentil proteins were prepared without buffer salts and without lecithin as emulsifier:
[0197] Reference liquid oat bran-based creamer analogue Ref.Cl,
[0198] Reference liquid oat bran-based creamer analogue Ref.C2,
[0199] The reference liquid oat bran-based creamers analogue Ref.Cl and Ref.C2 were prepared with the process as follows but with some differences.
[0200] The difference between Ref.Cl and Ref.C2 have different amount of oat bran (cf. tables 5).
[0201] Process:
[0202] Water was added in a tank and heated to 65°C. Oat bran was added and dispersed in the water during 20 min under shear with the Ystral X50 / 10 to obtain a plant dispersion. The Fat blend PO:CNO-70:30 and glucose syrup were added to the plant dispersion and mixed with the Ystral at high shear for 5 min to obtain a food pre-emulsion. The food pre-emulsion was heated at 110°C for 15 seconds through heat exchangers and went then through the homogenizer of the APV-HTST at 230 / 50 bars to form the reference liquid oat bran-based creamer analogues Ref.Cl or Ref.C2.
[0203] The recipe of the reference liquid oat bran-based creameranalogues Ref.Cl and Ref.C2 (i.e. obtained before spray drying) is provided in table 5.
[0204]
[0205] Table 5
[0206] Example 5: Properties of plant-based liquid creamer analogue emulsions
[0207] The properties of the following creamer analogues were assessed:
[0208] -invention liquid lentil-based creamer analogue Al and Bl of example 2 obtained before spray drying,
[0209] -reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl of example 3 obtained before spray drying,
[0210] -reference liquid oat bran-based creamer analogue Ref.Cl and Ref.C2 of example 4 obtained before spray drying.
[0211] • Microscopy
[0212] Method:
[0213] The Zeiss Axioplan optical microscope was used to observe the microstructure of the emulsions. Micrographs were taken with the 20x and 40x objectives using the ProgRes camera and ProgRes CapturePro software.
[0214] Results:
[0215] The results are shown in figure 1. It can be observed that the creamer analogue emulsions prepared with oat bran only (i.e. reference liquid oat bran-based creamer analoguew Ref.Cl and Ref.C2) have large fat droplets. The creamer analogue emulsions prepared with lentil protein concentrate or lentil flour only (i.e. reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl) exhibit smaller fat droplets compared to the creamer analogue emulsions prepared with oat bran only (i.e. reference liquid oat bran-based creamer analogues Ref.Cl and Ref.C2). The creamer analogue emulsions comprising both lentil protein ingredients and oat bran (i.e. invention liquid lentil-based creamer analogues Al and Bl) showed the smallest fat droplets. In particular, the addition of oat bran to lentil proteins (flour or concentrate) decreases the droplet size to below 1 pm. This suggests that creamer analogue emulsions with lentil protein ingredients and oat bran have enhanced stability, even in the absence of added emulsifier such as lecithin.
[0216] As mentioned above, creamer analogues Ref.Cl, Ref.C2, Ref.Al and Ref.Bl show larger fat droplet size than the creamer analogues Al and Bl. This larger droplets size can be detrimental during processing and industrialization of the product. Indeed, a larger droplet size will accelerate destabilization phenomenon, such as creaming phenomenon, that can occur during the process or during storage prior to heat treatment and drying. This can lead to product inhomogeneity and result in unpleasant and undesired sensory properties.
[0217] Regarding the type of lentil ingredient, the lentil protein concentrate (cf. invention liquid lentil-based creamer analogues Al) and the lentil flour (cf. invention liquid lentil-based creamer analogues Bl) show similar performance in creamer analogue emulsions. In particular, the creamer analogue emulsions with lentil protein concentrate and flour have similar microstructures.
[0218] • Particle size distribution
[0219] Method:
[0220] The particle size distribution of the different liquid creamer analogues obtained before spray drying was measured with a Malvern Mastersizer 3000 with the Hydro MV wet dispersion unit. Spherical particles were assumed, and the refractive indices used for the Fat blend PO:CNO-70:30 and water phase were 1.465 and 1.33, respectively. A sample was added to the wet dispersion unit until a laser obscuration of 4-10% was reached. The dispersion was performed with a stirrer speed of 1990 rpm and the average of three measurements is collected. Results:
[0221] The results are shown on figure 2.
[0222] The particle size distribution data confirm the microscopy results. In particular, creamer analogue emulsions with lentil protein ingredients and oat bran (i.e. invention liquid lentil-based creamer analogues Al and Bl) showed an important ratio of small fat droplets, in particular fat droplets having a size below 1pm. On the other hand, the creamer analogue emulsions prepared without lentil protein ingredients only (i.e. reference liquid lentil-based creamer analogues Ref.Al and Ref.Bl) have fat droplets having more important size.
[0223] Table A below shows the D[3;2] value of the different creamer analogues sample.
[0224] Table A
[0225] Example 6: Reconstitution and stability properties of liquid or powdered plant-based creamer analogues
[0226] • Reconstitution trials
[0227] The invention powdered lentil-based creamer analogue Bl of example 2 was reconstituted into cold water to evaluate the reconstitution properties of the invention powdered creamer analogue in cold conditions.
[0228] Method:
[0229] Reconstitution properties was assessed as follows. The invention powdered lentilbased creamer analogues Bl was poured at a concentration of 16% into water at 4°C. The emulsions were observed visually with the naked eyes until complete dissolution. The emulsions were also observed by microscopy after complete dissolution. The microscopy observations were performed according to the microscopy method provided in example 5.
[0230] Results:
[0231] The results are shown in figures 3 and 4.
[0232] It can be observed that powdered creamer analogue emulsions with combination of lentil protein ingredient and oat bran (i.e. invention powdered lentil-based creamer analogues Bl) reconstitute well in cold water even at 16% concentration. Complete dissolution was achieved in less than 30 seconds. They provide homogenous creamer analogue upon reconstitution and no lumps are observed even in the absence of any added emulsifier such as lecithin (Figure 3).
[0233] After reconstitution, the invention powdered lentil-based creamer analogue Bl exhibits a good emulsion microstructure with small and discrete fat droplets even in the absence of any added emulsifier such as lecithin (Figure 4). In particular, it can be observed an important ratio of fat droplets having a size below 1pm.
[0234] • Stability in coffee
[0235] To assess the stability of the liquid and powdered creamer analogues, stability trials in coffee in cold conditions were performed on the invention liquid or powdered lentil-based creamer analogues Bl of example 2 and the reference liquid or powdered lentil-based creamer analogues Ref.Bl of example 3. Stability trials in coffee allow to assess stability of the creamer analogues in hard and / or acidic beverages.
[0236] Method:
[0237] The resistance of the liquid or powdered creamer analogues to water hardness in coffee was tested as follow. Hard water was prepared with CaCI2 and MgCI2 6H2O to have a final water hardness of 400 ppm of Ca2+. This water was then cooled down to 4°C in a fridge. In beakers, 1 g of soluble coffee and 4.5 g of the tested creamer analogue were weighed and mixed to obtain a homogeneous powder. 100 mL of 400 ppm water at 4°C was added to it and the mixture is stirred with a spoon until the coffee and the creamer analogue was dissolved. Pictures were taken just after mixing and after 10 minutes to see if the creamer analogue flocculates. Results:
[0238] The results are shown in figures 5 and 6.
[0239] Whatever their format (liquid or powdered), it can be observed that the invention liquid or powdered lentil-based creamer analogues Bl have good stability in coffee with hardness of 400ppm. No flocculation is observed 10 minutes after contacting the creamer analogue with coffee even in the absence of any buffer salts.
[0240] On the other hand, the reference liquid or powdered lentil-based creamer analogues Ref.Bl are not stable in coffee and exhibit feathering / protein flocculation in the absence of any buffer salts.
[0241] These observations suggest that the addition of oat bran improves coffee stability properties of creamer analogues based on plant proteins (e.g. lentil proteins). In particular, it makes possible to achieve a creamer analogue based on plant proteins which is coffee stable, even in the absence of any buffer salts.
[0242] Example 7: Sensory evaluation of powdered plant-based creamer analogue
[0243] Method:
[0244] The invention powdered lentil-based creamer analogues Al and Bl of example 2 were prepared respectively according to example 2.
[0245] After preparation, 10 g of the different powdered creamer analogues were added into 400 mL of 21°C (or 4°C for some tests) milli-Q water. 10 minutes after addition in water, the sensory properties of the different creamer analogues obtained were assessed. In particular, the sensory properties of the different creamer analogues were assessed monadically by people trained to assess the off-flavours perceived in mouth and creaminess perceived in mouth.
[0246] The intensity of the off flavours was characterized by providing a score from 0 (no off flavours perceived in mouth) to 5 (high off flavours perceived in mouth).
[0247] The intensity of the creaminess was characterized by providing a score from 0 (no creaminess) to 5 (high creaminess).
[0248] The dry mouthfeel describes the degree to which the food product turns into a thick paste that is difficult to dissolve and remove from the palate. The dry mouthfeel is accompanied by perception of dryness in mouth requiring saliva pumping. The intensity of the dry mouthfeel was characterized by providing a score from 0 (no dry mouthfeel perceived in mouth) to 5 (high dry mouthfeel perceived in mouth).
[0249] The intensity of the smoothness was characterized providing a score from 0 (texture with many grains felt in mouth) to 5 (smooth texture with no grains felt in mouth).
[0250] Results:
[0251] The invention powdered lentil-based creamer analogues Al and Bl exhibited good sensory properties: enhanced creaminess, limited dry mouthfeel and very smooth texture. The invention powdered lentil-based creamer analogues Al and Bl exhibited pleasant taste and limited off-notes.
[0252] Example 8: Impact of beta-glucans content in oat bran on powdered creamer properties.
[0253] An invention powdered lentil-based creamer analogue B2 was prepared with the same process as for the invention powdered lentil-based creamer analogue Bl of example 2. However, the only difference is that the oat bran with 28% beta-glucans of the invention powdered lentil-based creamer analogue Bl was replaced by an oat bran with 22% betaglucans.
[0254] The recipe of the powdered lentil-based creamer analogue B2 is provided in table 6.
[0255] Table 6
[0256] • Reconstitution trials

[0260] The emulsions obtained after complete dissolution were observed visually.
[0261] The emulsions were also observed by microscopy after complete dissolution. The microscopy observations were performed according to the microscopy method provided in example 5.
[0262] Results:
[0263] It was observed that the invention powdered lentil-based creamer analogue B2 has similar performance as the invention powdered lentil-based creamer analogue Bl. In particular, it also reconstitutes well in cold water even at 16% concentration. In particular, complete dissolution was achieved in less than 30 seconds. It also provides a homogenous creamer analogue upon reconstitution and no lumps are observed even in the absence of any added emulsifier such as lecithin.
[0264] After reconstitution, the invention powdered lentil-based creamer analogue B2 also exhibit a good emulsion microstructure with small and discrete fat droplets even in the absence of any added emulsifier such as lecithin (Figure 7). In particular, it can be observed an important ratio of fat droplets having a size below 1pm (Figure 7).
[0265] Stability in coffee Stability trials in coffee in cold conditions were performed on the invention powdered lentil-based creamer analogues B2. Stability trials in coffee allow to assess water hardness stability and acid stability of the creamer analogue.
[0266] Method:
[0267] The stability in coffee of the powdered creamer analogue was tested according to the method of example 6.
[0268] Results:
[0269] The results are shown in figure 8.
[0270] The invention powdered lentil-based creamer analogue B2 also show similar performance in terms of coffee stability as the invention powdered lentil-based creamer analogue Bl.
[0271] The invention powdered lentil-based creamer analogues B2 have good stability in coffee with hardness of 400ppm. No flocculation is observed 10 minutes after contacting the creamer analogue with coffee even in the absence of any buffer salts.
[0272] • Conclusion
[0273] The invention powdered lentil-based creamer analogues B2 and Bl have similar microstructures and similar performance in terms of reconstitution properties and coffee stability. This shows that the beta-glucans content in the bran ingredient have no impact on microstructures, reconstitution properties and coffee stability of creamer analogues.
[0274] Although the invention has been described by way of example, it should be appreciated that variations and modifications may be made without departing from the scope of the invention as defined in the claims.
