Description

PT-1960-WO-PCT SPRAY DRIED OLEOSOMES CONCENTRATE CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of European Patent Application 24187093.0 filed July 8, 2024, which is incorporated by reference herein in its entirety. FIELD OF THE INVENTION

[0002] The invention relates to a process for preparing an oleosome-saccharide composition, by using spray-drying. BACKGROUND OF THE INVENTION

[0003] Dried oleosomes offer advantages in terms of stability, storage, and transport, as they are less prone to microbial degradation and do not require refrigeration. Additionally, their dry form facilitates incorporation into a wider range of formulations and processing environments.

[0004] Drying oleosomes, and emulsions in general, is very challenging since these colloidal particles are susceptible to colloidal instability at high temperatures. Either coalescence, flocculation or oiling out can take place during spray-drying, by which oleosomes integrity is lost together with a detrimental functionality. Therefore, it is important to properly select the right carriers and their concentration to provide protection to the oleosomes during spray-drying and to obtain good reconstitution properties of the generated powder.

[0005] Many studies have been done within the field trying to solve these problems. An alternative technology to obtain a powder format of oleosomes or emulsions could be by freeze-drying. However, this technology is very expensive and would reflect in a significant cost increase to the product. Moreover, it is difficult to find this equipment at large scale.

[0006] Other drying methods with hot surfaces or hot air are not suitable for emulsions since they are too harsh.

[0007] There is thus still a need to provide oleosomes in powder form by using a mild processing technology. The current invention provides for such a process and the product thus obtained.PT-1960-WO-PCT SUMMARY OF THE INVENTION

The oleosomes concentrate

[0023] Oleosomes, also known as "oil bodies", "lipid bodies", "lipid droplets" or "spherosomes", are pre-emulsified droplets or vesicles of oil stored in plant seeds, nuts or any other plant part and used as energy source for plant growth and metabolism. Oleosomes are typically extracted from cells by a process of grinding the seeds or nuts in the presence of an aqueous solution, such as water, followed by solid-liquid separation to obtain an aqueous dispersion (also called aqueous suspension) of oleosomes and a residual oleosome containing fraction.

[0024] “Isolated vegetable oleosomes” are pre-emulsified droplets or vesicles of oil that are present in cells and that have been obtained, taken, extracted and / or isolated from these cells, after wet grinding of plant seeds.

[0096] The further emulsifier can be selected form the group consisting of lecithin, fractionated lecithin, hydrolyzed lecithin, mono and di-glycerides, sodium stearyl lactylate, combinations of two or more thereof and the like.

[0097] In an aspect of the invention, lecithin is added.

[0098] Typical carriers employed in the food industry are maltodextrins, gums, proteins and other carbohydrates. These carriers form a physical barrier around the component(s) of interest while water is removed during spray-drying.

[0099] In the present invention, it was surprisingly found that using conventional carriers is not enough to maintain the integrity of oleosomes (such as particle size distribution, microstructure and the like).

[0100] Without being bound by a specific theory, it was observed that polysaccharides, preferably pectins, preferably derived from citrus fruits, are adsorbed to the interface of oleosomes as an extra protective layer to effectively preserve the integrity of oleosomes. Preferably this pectin adsorption or also called electrostatic deposition is obtained by bringing the pH to the acid range (3-5) to generate positive charges in the oleosomes interface (due to protein presence) and negativePT-1960-WO-PCT charges in the pectin molecules. These opposite charges will generate attraction and produce pectin adsorption inducing the formation of protective layers around the oleosomes. Further combining the polysaccharides such as preferably citrus pectin, with the oligosaccharides such as preferably maltodextrin, may result in an oleosome powder preserving the colloidal stability and providing good reconstitution behaviour.

The nutritional composition may also be in the form of a pudding or a jelly, or the form of a cookie or a snack bar, or any other form.

[0127] In an aspect of the invention, the nutritional composition is an infant formula.

[0128] The infant food product or infant formula is a term well-known in the art and it refers to food that is specifically manufactured for infants and it may be characterized in that it is soft, and easily consumable by infants and has a nutritional composition adapted to the specific needs at each growth stage.

[0129] The infant formula may be in the form of a liquid, such as a ready-to-drink infant food product. It can also be in the form of a formula base, i.e., a powder or a concentrated liquid,PT-1960-WO-PCT to be dissolved in water or another fluid for the preparation of a ready-to-drink infant food product. The infant food product may also be in the form of a pudding or a jelly, or in the form of a cookie or a snack bar, or in any other form.

[0134] In an aspect of the invention, it relates to the use wherein the spray-dried oleosomes are reconstituted in liquid. Benefits of the present invention

[0135] Without being bound by a specific theory, the present invention provides amongst others for the following advantages: the process of the present invention allows obtaining a powder and it may substitute the use of a final UHT process. The product of the present invention provides amongst others the following advantages: (i) longer shelf-life, (ii) significant reduction of transport costs, (iii) reduced storage capacity to store same amount of oleosomes solids, (iv) potentially better oxidative stability, (v) more freedom to formulate (customer convenience) without taking into account the waterPT-1960-WO-PCT coming with the liquid format, (vi) synergistic effect between maltodextrin and pectin.

[0136] The present invention has demonstrated that there is a synergistic effect due to the presence of polysaccharides and oligosaccharides in the oleosomes and saccharides containing powder (spray-dried oleosomes). The presence of oligosaccharides alone is not sufficient to obtain a white powder.

[0137] The presence of polysaccharides alone seems to improve the colour better than the presence of oligosaccharides, but then the product is difficult to reconstitute.

[0138] Surprisingly, it was found that due to the presence of polysaccharides and oligosaccharides together, the product is white, and the powder can be easily reconstituted.

[0139] Surprisingly, the product of the present invention and / or the process of the present invention demonstrates superior performance in terms of powder appearance, flowability, and reconstitution properties. These benefits can be attributed to the specific composition of the feed material. The absence of either one or both carrier materials such as oligosaccharides and / or polysaccharides, resulted in less desirable powder characteristics such as clumping, poor solubility, and / or uneven texture.

[0140] The present invention demonstrates unexpected technical advantages, including improved solubility, enhanced stability, and optimized particle morphology.

[0141] In the present invention it is shown that the presence of oligosaccharides and polysaccharides may have a substantial impact on the surface shape. Particle aggregation may affect the end product's stability, dispersibility, and solubility. The aggregation may also be due the free oil causing the particles to adhere.

[0142] The present invention is demonstrated but not limited to the examples given herein. EXAMPLES Analytical methods Protein measurement

[0136] The protein content of the oleosomes concentrate was determined by the amount of nitrogen in the sample. This amount of nitrogen was analyzed using a combustion method. Combustion of the sample was performed at 1100°C. The amount of nitrogen was determined using a conductivity detector (LECO TruMAc). The protein content was calculated by multiplying the amount of nitrogen analyzed by 6.25.PT-1960-WO-PCT Measurement of total oil content

[0137] The amount of oil in the oleosomes concentrate was determined using the Soxhlet extraction method. It is expressed on total dry substance of the oleosomes concentrate. Measurement of free oil

[0138] The spray dried powder was reconstituted in demineralized water to form a suspension. The suspension was weighed and mixed with hexane in an Eppendorf® tube. The tube was then centrifuged for 5 minutes. A phase separation was noted and pipetted in another tube. The tube was then left under a laminar hood overnight for the hexane to safely evaporate. The remanent was weighed as the free oil of the system. Measurement of oil present in oleosomes

[0139] The amount of oil present in the isolated oleosomes of an oleosomes concentrate was calculated by subtracting the amount of free oil from the total oil content of the oleosomes concentrate. Measurement of dry substance

[0140] The percentage dry substance (%DS) of the oleosomes concentrate was determined gravimetrically using an MA150 infrared balance (Sartorius). About 2 g of material (i.e. the wet weight (WW)) is applied on an aluminum dish with glass fiber pad. The moisture is evaporated at 105 °C until a stable weight is reached (i.e. the dry weight (DW)). The percentage dry substance is calculated according to the following formula: ^^^^ %^^^^ ൌ^^ 100 ^^^^

[0141] The dry substance is including oils, proteins, fibers, or other solids. The dry substance is only excluding water. Measurement of ash content

[0142] The ash content of oleosomes concentrate was measured according to ISO 936 method.PT-1960-WO-PCT Scanning Electron Microscopy

[0143] Spray dried oleosomes powders were micrographed using NeoScope JCM-5000 SEM. The powders were mounted on adhesive coated aluminium stubs. Visual Observation and powder reconstitution

[0144] The spray dried powders were visual observed to detect powder feel, color and smell. The powders were also reconstituted in water by stirring in 15 grams of powder in 135 grams of water at 40 C.

[0145] The sample was evaluated in the first hour on parameters such as phase separation and / or oiling out (small oil droplets on top of the liquid surface). EXAMPLES Extraction of oleosomes and step of obtaining an oleosomes concentrate

[0146] In order to isolate oleosomes from sunflower, 130 kg of dehulled seeds from (high- oleic) sunflower was soaked during 22 hours in deionized water in a ratio of seeds to water of 1:2 at a temperature of 4°C. The soaking water was brought through a shaking sieve equipment and the soaked seeds were rinsed with deionized water in a ratio of seeds to water of 1:2 at a temperature of 4°C. The washed seeds were ground with deionized water in a ratio of seeds to water of 1:2 at a temperature of 4°C using a toothed colloid mill (Fryma Koruma) at a flow rate of 200 L / h to obtain a sunflower slurry. On average, the slurry presented a dry matter content of 18.5 wt.%. The obtained slurry was subjected to a solid-liquid separation step using a decanter (Flottweg) set at 185 L / h. The decanter liquid phase (oleosome extract) is collected, and a side stream, the decanter solid phase (cake) is obtained. The oleosome extract presented a dry matter content of ~11 wt.%. The oleosome extract was concentrated by means of a centrifuge (GEA) running at a bowl speed of 12000 rpm, and flow rate 150 L / h.

[0147] After centrifugation, the oleosome concentrate and oleosome depleted composition are obtained.

[0148] Pressure was applied on both outlets to reduce air incorporation and obtain a dry matter content of ~40 wt.% in the oleosome concentrate (light phase) and ~4% wt.% in the oleosome depleted composition (heavy phase). The centrifuge light liquid phase (oleosome concentrate) was collected in a tank, and it was standardized to 15 wt.% dry matter and pH adjusted to 8. Afterwards, a second centrifugation step was applied to the standardized cream. ThePT-1960-WO-PCT centrifuge light liquid phase was collected, which presented 47% dry matter. This second centrifuge light phase is called washed oleosome concentrate. It was standardized to 35 wt.% dry matter, containing 32.7 wt.% oil, and 1.5 wt.% protein. This standardized washed oleosome concentrate was then subjected to sterilization using a UHT GEA system (heat plate exchanger, 136°C for 5s) to extend its shelf-life.

[0149] This quality of oleosome concentrate was used for Example 1, Comparative example 1, Comparative example 2. Spray-drying step of the oleosome concentrate Example 1

[0150] The oleosome concentrate sample described above was mixed with HCl 1N solution till pH 3.5 and mixed further with pectin solution (in demi-water) and maltodextrin solution (in demi-water), stirred at 800 RPM, for one hour. The concentrations of the carriers (maltodextrin and citrus pectin) were added according to Table 1. Comparative example 1

[0154] After these mixing steps, the materials were transferred to the feed of a single-stage spray-dryer (GEA mobile minor) with an evaporation capacity between 0.5 and 6 kg / h. A two- fluid nozzle was employed to produce droplets. The air inlet and product outlet temperature were 150°C and 70°C, respectively, to assure that powder with low moisture content was obtained. Extraction of oleosomes and step of obtaining an oleosomes concentrate

[0155] The (high oleic) sunflower kernels (25 kg) were soaked in reversed osmosis (RO)PT-1960-WO-PCT water at 4°C, during 22 hours. The soaked kernels were sieved (1 mm), the soaked kernels were collected. The kernels were further washed with cold deionized water and sieved (1 mm). The kernels were subjected to colloid milling with water solution (20 / 80) using the Fryma Koruoma MZ130 (Toothed mill). Milling parameters were: 2880 rpm speed, 17 rpm H2O flow, 20 rpm kernel flow, milling gap: no gap (0 mm). After milling, slurry was collected and decanted (Alfa Laval) using the following parameters: 5000 rpm bowl speed, 5 RPM Speed, 200 L / h feed. The decanted oleosome extract presented a composition of 14.6 wt.% dry matter, 9.8 wt.% oil, 2.3 wt.% protein, and 0.3 wt.% ash. This material (~65 kg) was then adjusted to pH 8 and subjected to microfiltration using an Alfa Laval unit. Four diafiltration steps were applied to remove mainly polyphenols. The final concentration step was employed so the microfiltered oleosomes reached 29.7 wt.% dry matter, out of which 25.9 wt.% was oil and 3.7 wt.% protein. This microfiltered material was sterilized in a UHT direct steam injection system (SPX flows) under the following conditions: 142°C for 3s, and 70°C, respectively, to assure that powder with low moisture content was obtained. Collected material was packed in Rapak sterile multilayer bags. This quality of oleosome concentrate was used for Comparative example 3.
