Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a composite beverage of acacia flowers, mulberries and walnuts and a production device thereof. Background Art

[0002] Acacia flowers are fragrant and pleasant, and are suitable natural plant spices. In addition to being eaten fresh, acacia flower products are also widely processed. In recent years, there have been many reports on the use of acacia flowers to make flower jams and teas. Based on this, we hope to use acacia flowers as one of the raw materials for our functional beverages, and use the extraction method or pulping method to prepare acacia flower juice based on the different application backgrounds of acacia flower beverages.

[0003] Mulberry is the fruit of the Moraceae plant, rich in active ingredients such as anthocyanins, polysaccharides, and polyphenols. Its processed products such as wine, vinegar, and juice have been widely studied. Ultrahigh pressure assisted extraction technology is widely used in the extraction of mulberry anthocyanins due to its high efficiency and environmental protection. However, traditional solvent extraction methods may cause degradation or loss of active ingredients due to high temperature or the use of chemical solvents during the extraction process, affecting the quality and functionality of the product.

[0004] As a nut with high nutritional value, the processing technology of walnut mainly focuses on the extraction of walnut oil, walnut protein and other ingredients. The aqueous enzymatic method is a common method for extracting walnut hydrolyzate, but it is easy to form an emulsion during the extraction process, resulting in stratification and affecting the stability of the compound beverage. In addition, the yield of walnut protein extracted by the aqueous enzymatic method is low, and the residue may precipitate, reducing the taste and quality of the product. In the prior art, the optimization of walnut extraction technology still faces many challenges, especially in improving extraction efficiency and maintaining nutrients.

[0005] In addition, in the prior art, the cleaning of acacia flowers mostly relies on traditional high-pressure water flow and hard brushes. Since the petals of acacia flowers are delicate, this cleaning method easily causes the petals to be damaged, resulting in the loss of active ingredients (such as rutin, flavonoids, etc.), which in turn affects the flavor and nutritional value of the beverage during subsequent processing.

[0006] At present, the compound beverages containing acacia flowers, mulberries or walnuts on the market have relatively traditional and single nourishing and health-care effects, which cannot meet consumers' demand for beverages with beauty, anti-aging and multiple health-care effects. In addition, influenced by healthy living, more and more consumers are turning to green plant beverages. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a locust flower, mulberry and walnut compound beverage and a production device thereof. By precisely controlling the ratio of raw materials and using a gentle and efficient preparation device, the quality of the locust flowers is ensured while ensuring the high quality, high stability and comprehensive improvement of the health attributes of the locust flower, mulberry and walnut compound beverage.

[0013] Step 4, extracting walnut juice: placing the block walnuts in a pulper to make walnut pulp and adding soybean lecithin to homogenize, then adding monoglyceride and sucrose ester to emulsify, and finally adding sodium carboxymethyl cellulose and xanthan gum to obtain walnut juice;

[0014] Step 5, preparing mulberry concentrate: mixing mulberry powder and water, and compressing to obtain mulberry concentrated juice, adding vitamin C tablets and homogenizing, and then adding emulsifiers and thickeners to obtain mulberry juice;

[0015] Step six, mixing preparation: Sophora japonica flower juice, mulberry juice, walnut juice and milk are mixed according to weight percentage, sterilized, and antioxidants are added to obtain a Sophora japonica flower, mulberry and walnut composite beverage.

[0016] The processing method of mulberries is as follows: fresh and clean mulberries are selected, washed and dried, and ground into powder in a grinder to obtain mulberry powder; the processing method of walnut kernels is as follows: fresh walnuts are selected, the shells and inner membranes are removed, and the walnut kernels are cut into blocks.

[0017] Furthermore, in step 2, the concentration of the sugar aqueous solution is 70%, and citric acid is added to adjust the pH to 4.2.

[0018] Furthermore, in step three, the dried Robinia pseudoacacia flowers are treated by extraction method, wherein the dried Robinia pseudoacacia flowers with an opening degree of 50% are selected, purified water is added under an extraction temperature of 90°C, the ratio of dried Robinia pseudoacacia flowers to purified water is 1:5, and the Robinia pseudoacacia flower extract is obtained by filtering after water bath extraction for 3 hours.

[0019] Furthermore, in step three, the fresh locust flowers are processed by a pulping method, wherein the flower spikes of fresh locust flowers with an opening degree of 50% are selected, the pedicels are selected and washed through a preparation device, and purified water is added, the ratio of fresh locust flowers to purified water is 2:1, and the flowers are heated to 100°C in the preparation device and boiled for 10 to 20 minutes, and then placed in a pulper to grind into pulp and filter to obtain a locust flower extract.

[0020] Furthermore, in step three, the contents of ingredients added to the Sophora japonica extract are: 2.3% erythritol, 0.07% citric acid, 0.05% cyclamate, 6% Sophora japonica honey, 0.15% acid-resistant CMC, 0.15% pectin and 0.15% guar gum.

[0021] Further, in step 4, 12-16% soybean lecithin is added and homogenized at 70° C., and then 0.1% monoglyceride and sucrose ester are added for emulsification, and finally 0.15% sodium carboxymethyl cellulose and 0.05% xanthan gum are added;

[0022] In step five, pure water and mulberry powder are added in a water-to-material ratio of 5:1, and water extraction is carried out at 90° C. for 50 minutes, and then mulberry concentrated juice is obtained at 60° C. to 70° C. and a pressure of 430 MPa. The content of the added vitamin C tablet is 0.14%.

[0023] Furthermore, in step six, the mixing percentages are: 15% Sophora japonica juice, 10% mulberry juice, 5% walnut juice and 70% milk, and sterilized at 95° C. for 15 minutes.

[0024] The above scheme has the following beneficial effects:

[0025] 1. This solution uses acacia flowers to have a unique flavor and taste: through the combination of acacia flowers, mulberries and walnuts, the drink has the fragrance of acacia flowers, the sweetness of mulberries and the mellowness of walnuts, forming a unique flavor layer to meet consumers' pursuit of the original taste of natural ingredients; using acacia flower honey instead of traditional white sugar not only increases the sweetness, but also avoids the impact of high sugar content on the product's blood pressure and lipid-lowering effects, while improving the health attributes of the drink.

[0026] 2. This plan focuses on the nutrition and functionality of the beverage: Robinia flowers are rich in active ingredients such as rutin, which have antioxidant and anti-inflammatory effects; mulberries are rich in anthocyanins, which help improve blood circulation and anti-oxidation; walnuts are rich in unsaturated fatty acids and protein, which contribute to brain health and cardiovascular protection; through scientific extraction and preparation processes, the nutrients and active substances in the raw materials are retained to the maximum extent, so that the beverage has both nutritional value and health functions. In addition, the beverage has both floral and fruity fragrance and mellow taste, which meets the needs of modern consumers for natural, healthy and functional beverages and has broad market potential.

[0027] 3. This solution improves product stability through process innovation: acacia flower honey is prepared by frying acacia flower water solution with granulated sugar, which increases the sweetness and flavor of the drink while avoiding the health risks of traditional high-sugar formulas; emulsifiers such as soybean lecithin and monoglyceride and stabilizers such as xanthan gum are added to walnut juice to effectively improve the emulsification and stability of the drink and solve the problems of fat floating and precipitation in the traditional water-enzyme process; mulberry concentrate is extracted by water, combined with high-pressure homogenization and vitamin C protection, which maximizes the retention of the active ingredients and flavor of mulberries while improving the stability of the product.

[0028] 4. This solution uses healthy and safe additives: erythritol and other sweeteners that are low in calories, non-cariogenic, and have little effect on blood sugar. This not only improves the taste of the drink, but also ensures the safety of the product. It is suitable for diabetic patients and people with a healthy diet. No additional white sugar is added to the drink itself, which reduces the total sugar content of the drink, meeting the demand of modern consumers for low-sugar, healthy drinks.

[0029] 5. This solution ensures product authenticity: by increasing the proportion of main raw materials (such as acacia flowers, mulberries, and walnuts), the flavor of the beverage is closer to the original flavor of the ingredients. At the same time, it prevents the counterfeiting of traditional plant beverages to a certain extent, and ensures the quality and authenticity of the product.

[0030] A device for making a composite beverage of acacia flower, mulberry and walnut comprises a preparation tank, the preparation tank signal is connected to a controller, a cleaning chamber and a processing chamber are arranged from top to bottom in the preparation tank, a feeding port connected to the outside is opened at the top of the cleaning chamber, and the processing chamber is used to prepare acacia flower honey or acacia flower extract from acacia flowers;

[0032] The first filter assembly includes a first inclined plate, the first inclined plate includes a first upper inclined plate near the high side and a first lower inclined plate near the low side, one end of the first upper inclined plate away from the first lower inclined plate is slidably connected to the inner wall of the cleaning chamber, the two ends of the first lower inclined plate are respectively fixedly connected to the first upper inclined plate and hinged to the inner wall of the cleaning chamber, a plurality of impurity holes are opened on the first upper inclined plate, an impurity box is fixedly connected to the bottom of the first upper inclined plate, and a first filter screen is provided on the first lower inclined plate, and the first filter screen is used to filter the acacia flower petals to the second filter assembly;

[0033] The second filter assembly includes a second inclined plate, the second inclined plate is inclined in the opposite direction to the first inclined plate, the second inclined plate includes a second upper inclined plate close to the high side and a second lower inclined plate close to the low side, a fan is provided on the preparation tank, a ventilation hole connecting the fan output port and the inside of the cleaning chamber is opened on the preparation tank, a second filter screen is opened on the second inclined upper inclined plate, the second filter screen is used to filter the calyx and incomplete petals of the acacia flower, a recovery box is fixedly connected to the bottom of the second filter screen, and an end of the second lower inclined plate away from the second upper inclined plate is fixedly connected to the roller assembly;

[0034] The impurity box and the recovery box are both connected with a discharge pipe, which is used to discharge impurities, acacia calyx, incomplete petals and clean water in the rinsing process to the outside of the preparation tank;

[0035] The roller assembly includes a support, a lower pressure rod and a cleaning roller, the top of the lower pressure rod is fixedly connected to the first inclined plate, a first spring is fixedly connected between the lower pressure rod and the top of the support, the bottom end of the lower pressure rod passes through the support and is fixedly connected to the pressure plate, a second spring is hinged on the inner top wall of the support, the end of the second spring away from the support is hinged to the fixing rod, a symmetrically arranged connecting rod is hinged on the inner side wall of the support, both ends of the fixing rod are respectively fixedly connected to a side of the connecting rod close to the support, both ends of the cleaning roller are respectively rotatably connected to an end of the connecting rod away from the support, the cleaning roller is in rolling contact with the bottom of the pressure plate, the surface of the cleaning roller is coated with an anti-stick coating, a vibration motor is installed inside the cleaning roller, a valve is provided on the inner bottom wall of the support, and the valve is connected to the controller signal.

[0036] The principle of the above scheme is as follows: the acacia flowers to be cleaned are put into the feeding port, and the acacia flowers fall to the side of the first inclined plate near the high position. Water is passed through the cleaning pipe, and the water flow washes the acacia flowers to the side of the first inclined plate near the first filter screen. In the process of the acacia flowers from the high side of the first inclined plate to the low side of the first inclined plate, fine impurities fall into the impurity box through the impurity holes, and larger impurities are intercepted by the first filter screen. At this time, the acacia flowers reach the second inclined plate, and the acacia flowers are blown to the side near the cleaning roller by the fan. In this process, the second filter screen further filters the calyx and incomplete petals, and the filtered impurities fall into the recovery box. After the acacia flowers reach the inner bottom wall of the support, due to the intermittent addition of the acacia flowers to be cleaned above the first inclined plate, the weight on the first inclined plate presses the lower pressure rod downward, and the pressure plate presses the cleaning roller to squeeze the acacia flowers with a small force. When the acacia flowers on the first inclined plate reach the low side, the weight above the lower pressure rod disappears, and the first spring and the second spring drive the cleaning roller to reset, so that the cleaning roller can intermittently squeeze the acacia flowers to remove impurities. When the acacia flowers are cleaned, the valve is opened through the controller, and the cleaned acacia flowers fall into the processing chamber for subsequent processing.

[0037] The above scheme has the following beneficial effects:

[0038] 1. This solution achieves efficient cleaning and impurity separation of acacia flowers through the inclined surface design of the first inclined plate and the second inclined plate, combined with water flushing and fan blowing; the first inclined plate separates small and large impurities through the impurity holes and the first filter to ensure the cleanliness of the acacia flowers, and the second inclined plate further filters the calyx and incomplete petals through the second filter to ensure the quality of the acacia flowers.

[0039] 2. This solution achieves intermittent squeezing of acacia flowers through a roller assembly. Through the cooperation of the lower pressure rod, the pressure plate and the cleaning roller, impurities on the surface of the acacia flowers are gently removed while avoiding damage to the petals. The surface of the cleaning roller is coated with an anti-stick coating and has a built-in vibration motor, which effectively prevents the acacia flowers from sticking to the cleaning roller, thereby improving the cleaning efficiency and the stability of the equipment operation.

[0040] 3. This solution ensures the cleanliness and integrity of the acacia flowers through efficient cleaning and impurity separation, providing high-quality raw materials for the subsequent preparation of acacia flower honey and acacia flower juice. The gentle treatment of the acacia flowers during the cleaning process avoids damage to the petals and retains the flavor and nutrients of the acacia flowers to the maximum extent.

[0041] Furthermore, the inner side wall of the processing chamber is connected with a first feeding pipe for conveying sugar water, a second feeding pipe for conveying citric acid and a water feeding pipe for conveying purified water, a plurality of electric heating wires are arranged in the interlayer of the side wall of the processing chamber, and an electric stirring rod is fixedly connected to the bottom wall of the processing chamber;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The following is further described in detail through specific implementation methods:

[0053] Embodiment 1:

[0054] As attached Figure 1 Shown: A locust flower, mulberry and walnut composite beverage, comprising the following components in weight: 80 parts by weight of mulberries, 50 parts by weight of walnut kernels and 200 parts by weight of locust flowers.

[0055] The preparation steps of the acacia flower, mulberry and walnut composite beverage prepared according to weight parts are as follows:

[0056] Step 1, raw material preparation: mulberries, walnut kernels and acacia flowers are taken respectively by weight, wherein the acacia flowers are selected from fresh acacia flowers or dried acacia flowers, and the acacia flowers are washed by a preparation device. The mulberries are processed as follows: fresh and clean mulberries are selected, washed and dried, and ground into powder in a grinder to obtain mulberry powder; the walnut kernels are processed as follows: fresh walnuts are selected, the shells and inner membranes are removed, and the walnut kernels are cut into blocks to obtain block walnuts and mulberry powder respectively.

[0057] Step 2, prepare sophora japonica flower honey: weigh 100 parts by weight of washed sophora japonica flowers for preparing sophora japonica flower honey, add 70% sugar aqueous solution, then add citric acid to adjust the pH to 4.2 and weigh to obtain sophora japonica flower aqueous solution, fry 4 times the weight of the washed sophora japonica flowers to 150°C, mix with the sophora japonica flower aqueous solution and naturally cool to room temperature.

[0058] Step three, preparing Sophora japonica flower juice: washing the dry Sophora japonica flowers with a preparation device and then using an extraction method, wherein the dry Sophora japonica flowers with an opening degree of 50% are selected, and pure water is added at an extraction temperature of 90°C, the ratio of dry Sophora japonica flowers to pure water is 1:5, and the Sophora japonica flower extract is obtained by filtering after water bath extraction for 3 hours.

[0059] Or the fresh locust flowers are washed by a preparation device and then pulped. The fresh locust flowers are processed by the pulping method as follows: the flower spikes of fresh locust flowers with an opening degree of 50% are cleaned with pedicels and washed by a preparation device, and purified water is added. The ratio of fresh locust flowers to purified water is 2:1. The flowers are heated to 100°C in the preparation device and boiled for 10 to 20 minutes. Subsequently, the flowers are placed in a pulper, ground into pulp, and filtered to obtain a locust flower extract.

[0060] Then, ingredients were added to the Sophora japonica extract, including 2.3% erythritol, 0.07% citric acid, 0.05% cyclamate, 6% Sophora japonica honey, 0.15% acid-resistant CMC, 0.15% pectin and 0.15% guar gum.

[0061] Step 4, extracting walnut juice: placing walnut blocks in a beater to make walnut paste and adding 12-16% soybean lecithin, homogenizing at 70°C, then adding 0.1% monoglyceride and sucrose ester for emulsification, and finally adding 0.15% sodium carboxymethyl cellulose (CMC-Na) and 0.05% xanthan gum to obtain walnut juice.

[0062] Step 5, preparing mulberry concentrate: mixing mulberry powder and water, and compressing to obtain mulberry concentrated juice, adding purified water and mulberry powder at a water-to-material ratio of 5:1, and water extraction at 90°C for 50 minutes, and then obtaining mulberry concentrated juice at 60°C-70°C and 430MPa pressure, the content of added vitamin C tablets is 0.14%, and mulberry juice is obtained.

[0063] Step six, mixing preparation: 15% Sophora japonica flower juice, 10% mulberry juice, 5% walnut juice and 70% milk are mixed according to weight percentage, sterilized at 95° C. for 15 minutes, and antioxidants are added to obtain a Sophora japonica flower, mulberry and walnut composite beverage.

[0064] In this embodiment, a sophora japonica flower, mulberry, and walnut beverage is designed. By consulting literature and related materials, it is known that sophora japonica flower and mulberry are both medicinal and edible foods, and the best method and materials for preparing sophora japonica flower, mulberry, and walnut extracts are obtained. At the same time, sophora japonica flower contains a large amount of rutin and flavonoids, which have whitening and blood pressure lowering effects, and mulberry also has the function of beauty and anti-aging. According to the principle of "monarch, minister, assistant, and envoy" of traditional Chinese medicine, sophora japonica flower is used as the main drug and mulberry is used as the minister drug to add to the beverage. Finally, walnuts are added to improve the taste, and the combination of walnuts and mulberry also has the effect of promoting digestion.

[0065] As shown in Table 1, when preparing acacia flower, mulberry and walnut composite beverage, the optimal dosage of CMC-Na is about 0.15%. The appropriate amount of CMC-Na and xanthan gum can improve the taste and stability of the beverage, but excessive use may cause the beverage to be too viscous or taste bad. Therefore, the use of 0.15% CMC-Na in step 4 can not only ensure the stability of the beverage, but also obtain a higher sensory evaluation score. For the dosage of xanthan gum, although the table shows that the score is higher at low concentrations, considering that xanthan gum mainly plays a thickening and stabilizing role in the beverage, its dosage may need to be adjusted according to the specific formula and process. When extracting walnut juice in step 4, 0.05% xanthan gum has been added, and this amount is sufficient to meet the stability requirements of walnut juice.

[0066] Table 1 List of dosage of stabilizers for walnut mulberry tea protein beverage

[0067]

[0068] In addition, as shown in Table 2, when monoglycerides and sucrose esters are used alone, their emulsification stability shows a trend of first increasing and then decreasing with increasing concentration. At a concentration of 0.10%, the emulsification stability of both reaches a high level. When monoglycerides and sucrose esters are mixed in the same proportion, the emulsification stability also shows a similar trend, but the overall stability may be affected by the interaction of the two ingredients, so it is slightly different from when used alone. At a concentration of 0.1%, monoglycerides and sucrose esters can form a relatively stable emulsification system, which helps to evenly disperse the oil and water molecules in walnut dew, thereby improving the stability and taste of the drink. Appropriate amounts of monoglycerides and sucrose esters not only help to improve the emulsification stability of the drink, but may also have a positive effect on the taste and flavor of the drink. For example, they can improve the texture of the drink, making it more delicate and smooth.

The top of the lower pressure rod 8 is welded to the bottom of the first inclined plate 7, a first spring 9 is welded between the lower pressure rod 8 and the top of the support 10, the bottom end of the lower pressure rod 8 passes through the support 10 and is clamped with a pressure plate 13, a second spring 11 is hinged on the inner top wall of the support 10, and a fixing rod 24 is hinged on the end of the second spring 11 away from the support 10, a symmetrically arranged connecting rod 12 is hinged on the inner side wall of the support 10, both ends of the fixing rod 24 are respectively welded to the side of the connecting rod 12 close to the support 10, both ends of the cleaning roller 14 are respectively rotatably connected to the end of the connecting rod 12 away from the support 10, the cleaning roller 14 is in rolling contact with the bottom of the pressure plate 13, the surface of the cleaning roller 14 is coated with an anti-stick coating, a vibration motor is installed inside the cleaning roller 14, a valve 15 is provided on the inner bottom wall of the support 10, and the valve 15 is connected to the controller signal.

[0078] The specific implementation process is as follows: As a delicate raw material, the petals of acacia flowers are fragile and sensitive to mechanical impact. Traditional cleaning methods (such as high-pressure water flow or hard brush to remove impurities) easily cause petals to be damaged, affecting the integrity of the raw materials and the flavor and quality of subsequent products. Therefore, when cleaning acacia flowers, the acacia flowers to be cleaned are put into the feeding port 5, and the acacia flowers naturally fall to the side of the first inclined plate 7 close to the height. A proper amount of water flow is passed into the cleaning pipe 6, and the water flow intermittently flushes the acacia flowers at a relatively low pressure. The inclined surface design of the first inclined plate 7 is used to slowly flush the acacia flowers to the side of the first inclined plate 7 close to the first filter 2. The water flow flushing can effectively remove surface impurities while avoiding damage to the petals. In the process of the locust flowers moving from the side of the first inclined plate 7 near the high place to the side of the first inclined plate 7 near the low place, since the aperture of the impurity hole 3 can only pass through tiny impurities, during the process of the locust flowers sliding down from the first inclined plate 7, the water flow flushes the impurities so that the impurities fall into the impurity box 4 from the impurity hole 3. When the locust flowers slide down to the first lower inclined plate, since the aperture of the first filter screen 2 can only pass through the locust flowers, impurities larger than the locust flowers (such as pedicels, leaves, etc.) are intercepted by the first filter screen 2. Through the graded filtration of the impurity holes 3 and the first filter screen 2, impurities of different sizes can be effectively separated to ensure the cleanliness of the locust flowers and prevent impurities from entering the subsequent processing links.

[0079] When the acacia flowers reach the top of the second inclined plate 21, the fan 22 blows the acacia flowers to the side close to the cleaning roller 14. The blowing of the fan 22 can gently send the acacia flowers to the cleaning roller 14 to avoid mechanical shock. The second filter 20 further filters the calyx and incomplete petals, and the filtered impurities fall into the recovery box 19, further ensuring the quality of the acacia flowers and removing incomplete petals and calyx.

[0080] After the acacia flowers reach the inner bottom wall of the support 10, due to the intermittent addition of the acacia flowers to be cleaned above the first inclined plate 7, the weight on the first inclined plate 7 presses the lower pressure rod 8 downward, and the pressure plate 13 presses the cleaning roller 14 to squeeze the acacia flowers with a small force to remove the fine impurities remaining on the surface. When the acacia flowers on the first inclined plate 7 reach the lower side, the weight above the lower pressure rod 8 disappears, and the first spring 9 and the second spring 11 drive the cleaning roller 14 to reset. The intermittent squeezing design can gently remove impurities and avoid damage to the petals. The anti-stick coating and built-in vibration motor of the cleaning roller 14 effectively prevent the acacia flowers from sticking. The anti-stick coating is used to prevent the acacia flower petals from sticking to the surface of the cleaning roller 14, and the impurity removal mainly depends on the squeezing and vibration of the cleaning roller 14. The anti-stick coating will not affect the contact and removal of impurities with the cleaning roller 14, so that the anti-stick coating of the cleaning roller 14 effectively prevents the acacia flowers from sticking to the cleaning roller 14 while improving the cleaning efficiency of the acacia flowers. When the acacia flowers are cleaned, the controller opens the valve 15 , and the cleaned acacia flowers fall into the processing chamber 18 .

[0083] A pH sensor and a temperature sensor connected to the controller signal are also provided in the processing chamber 18, and an output pipe is connected to one side of the bottom of the processing chamber 18.

[0084] The specific implementation process is as follows: after the washed acacia flowers enter the processing chamber 18, sugar water, citric acid or pure water are added according to the preset steps for preparing acacia flower honey or acacia flower extract. For example, when preparing acacia flower honey, a 70% sugar water solution is delivered to the processing chamber 18 through the first delivery pipe, and citric acid is added through the second delivery pipe. The pH sensor is used to monitor and adjust the pH of the solution to 4.2 in real time, the heating wire 16 is started, the temperature in the processing chamber 18 is raised to 150°C, the electric stirring rod 17 is started, the sugar water solution and the acacia flowers are fully mixed, and naturally cooled to room temperature to obtain acacia flower honey.
