Description

Technical Field

[0001] The present application relates to the field of nutritional supplements, and more specifically, to a Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development and a preparation method thereof. Background Art

[0002] DHA (docosahexaenoic acid), as an important ω-3 polyunsaturated fatty acid, has always attracted much attention due to its positive effects on brain development, vision protection and cardiovascular health. Currently, the DHA supplement market mainly uses fish oil, algae oil and other raw materials, and the DHA in these raw materials is mostly in the form of Sn-1,3 glyceride. However, the absorption efficiency of this form of DHA in the human body is relatively limited, especially in children and adolescents, a critical growth and development stage. The demand for DHA is high, but the absorption capacity is relatively weak. This situation limits the full effectiveness of DHA in promoting brain development. There is an urgent need for a DHA supplement that can be efficiently absorbed and meet the needs of specific populations.

[0003] In order to improve the absorption rate of DHA, it was found that the fatty acid at the Sn-2 position is more easily hydrolyzed by pancreatic lipase and thus absorbed by the small intestinal mucosal cells. Therefore, the absorption efficiency of Sn-2 DHA in the human body is significantly higher than that of Sn-1,3DHA. Therefore, the current related technology studies provide DHA in the form of Sn-2 glyceride.

[0004] For example, Chinese patent application publication number CN110846346B discloses a microbial oil rich in DHA at the Sn-2 position and a method for preparing the same. The microbial oil contains no less than 23% DHA at the Sn-2 position of triglycerides. The method comprises inoculating a Schizochytrium strain (Schizochytrium, deposited with GDMCC No. 60733) into a fermentation medium for fermentation. The microbial oil contains a significantly higher proportion of DHA at the Sn-2 position of triglycerides than at the Sn-1 and Sn-3 positions of triglycerides, resulting in a significantly higher human absorption rate for DHA than microbial oils produced from conventional strains, promoting the absorption and utilization of the functional fatty acid DHA by the human body.

[0005] Currently, most Sn-2 DHA supplements available on the market are in the form of capsules, microcapsules, etc. Although these forms can ensure the stability of DHA, they are insufficient in taste and convenience. Summary of the Invention

[0006] In order to prepare a DHA nutritional supplement with better taste and higher absorption rate, the present application provides a Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development and a preparation method thereof.

[0007] In the first aspect, the present application provides a Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development, which adopts the following technical solution: A Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development comprises the following raw materials in parts by weight: 78-85 parts of Sn-2 DHA algae oil, 6-10 parts of gelatin, 3-6 parts of glycerin, 2-5 parts of sweet orange oil, 0.05-0.12 parts of sucralose, 0.05-0.15 parts of erythritol, 0.08-0.15 parts of walnut oil, 0.1-0.27 parts of a synergist, and 0.3-3 parts of water.

[0008] By adopting the above technical scheme, gel candy has broad market prospects as a convenient and popular snack form. Combining Sn-2 DHA with gel candy can not only improve the absorption rate of DHA, but also meet consumers' demand for healthy snacks, especially for children and adolescents, a group with a large demand for DHA and high taste requirements. In this application, Sn-2 DHA algae oil is used as the main ingredient, combined with other auxiliary materials, and made into a gel candy form to improve its taste. The intake method is more convenient, and the gel candy has a good taste and smell, is particularly suitable for children to eat, and improves compliance.

[0009] Moreover, the absorption rate of Sn-2 DHA is better. DHA at the Sn-2 position is more easily absorbed and utilized by the human body. It can more effectively penetrate the cell membrane and enter the brain cells, promoting the growth, development and signal transmission of brain nerve cells, thereby improving the brain's ability to concentrate. Gelatin is the main substance that forms the main structure of gel candy. It forms a gel network structure in water to wrap other raw materials, giving the gel candy a specific texture and shape. The hygroscopicity of glycerol can adjust the moisture content and flexibility of the gel candy, preventing the gel candy from hardening and cracking due to water loss during storage, keeping the candy soft and moist, and improving the taste. At the same time, the interaction between glycerol and gelatin enhances the stability and elasticity of the gel. The sweet orange aroma of orange oil adds a unique fruity flavor to the jelly candy, improving its taste and aroma. The addition of a small amount of sucralose provides sweetness, improving the mouthfeel and satisfying consumers' sweetness needs. Compared to sucrose, it is lower in calories and can be added in smaller quantities. Combined with a small amount of low-calorie erythritol, it further modifies the candy's taste and helps prevent tooth decay. Walnut oil is easily absorbed in the small intestine, preventing gastrointestinal discomfort such as bloating and diarrhea. Walnut oil, rich in unsaturated fatty acids, is also beneficial for brain development. It works synergistically with Sn-2DHA algae oil to promote brain cell growth and development, enhancing brain function. Walnut oil also adds nutritional value and a unique flavor to the product.

[0010] Finally, the Sn-2 DHA-based gel candy prepared in this application further improves the taste, is more conducive to absorption, promotes brain development, and improves bioavailability.

[0011] Optionally, the synergist includes the following raw materials in parts by weight: 0.05-0.15 parts of arachidonic acid and 0.05-0.12 parts of N-acetylneuraminic acid.

[0012] By adopting the above technical solution, arachidonic acid (ARA), a key substance for the development of the human brain and visual nerves, is crucial for the intellectual and visual development of infants and young children. Arachidonic acid at the Sn-2 position is more conducive to the body's absorption and utilization. Together with Sn-2 DHA algae oil, it can more comprehensively meet the brain's developmental fatty acid needs and promote the construction and improvement of the brain's neural network. N-acetylneuraminic acid participates in processes such as nerve cell adhesion, recognition, and signal transduction, promoting the growth and pulverization of brain neurons and improving the brain's learning and memory abilities.

[0013] Finally, the walnut oil in this application is rich in Omega-3 fatty acids, which helps to improve the absorption rate of DHA and promote brain development; Sn-2 arachidonic acid and DHA work synergistically to promote brain development and functional improvement; N-acetylneuraminic acid (sialic acid) plays an important role in the development of the brain and nervous system, can improve malnutrition, and promote the normal development of brain function in infants and young children.

[0014] Optionally, the Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development includes the following raw materials in parts by weight: 83.3 parts of Sn-2 DHA algae oil, 8.4 parts of gelatin, 4.5 parts of glycerin, 3.4 parts of sweet orange oil, 0.1 part of sucralose, 0.13 parts of erythritol, 0.1 part of walnut oil, 0.1 part of arachidonic acid and 0.11 parts of N-acetylneuraminic acid and 0.5 part of water.

[0015] By adopting the above technical solution, the product prepared with the above ratio has a better effect on brain development and a better taste and better overall performance.

[0016] In a second aspect, the present application provides a method for preparing Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development, using the following technical solution: A method for preparing Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development comprises the following steps: S1. Prepare the materials by weighing them according to the amount of raw materials to be added; S2. After mixing water, sucralose, and erythritol, gelatin, glycerin, orange oil, and walnut oil are added, and after heating to gelatinize, Sn-2 DHA algae oil and a synergist are added, and the mixture is stirred to obtain a gel solution; S3, processing the gelatin liquid into pellets to obtain pellet-shaped prototype gel candies, which are then dried, sorted and packaged.

[0017] By adopting the above technical scheme, gelatin is dissolved at high temperature through the gelatinization process and fully mixed with glycerin, water, etc. to form a uniform and stable gel solution. In this process, Sn-2 DHA algae oil, walnut oil, arachidonic acid and other oil raw materials are evenly dispersed in the gel solution, and orange oil, sucralose, erythritol, etc. give the product sweetness and aroma. Then, through the pill dropping process, the gel solution is dripped into the coolant, and the gel solution is quickly cooled and solidified to form a pill-shaped prototype of the gel candy. After subsequent steps such as drying, sorting, and packaging, Sn-2 DHA algae oil gel candy with high absorption rate and brain development promotion function is finally made. The raw materials work together to promote brain development, improve taste and texture, etc.

[0018] This application uses a pelletizing process, taking advantage of gelatin's gelling properties. At high temperatures, gelatin is in a sol state. As the temperature drops, the hydrogen bonding and other forces between its molecules increase, gradually transforming it into a gel state. In the cooling liquid, the gelatin molecules on the surface of the gelatin liquid first come into contact with the low-temperature environment and begin to solidify. As the cooling progresses, the entire droplet gradually solidifies into a pellet. During the dripping process, the gelatin liquid forms spherical droplets due to surface tension. After entering the cooling liquid, the gelatin liquid rapidly cools and solidifies, forming the pellet-shaped prototype of the gel candy.

[0019] Optionally, the specific drying operation in step S3 is: processing in a tumble dryer at a speed of 6-20 for 1-1.5 hours.

[0020] By adopting this technical solution, the rotating cage rotates at a speed of 6-20 gears. During this rotation, the pills continuously tumble and roll within the cage. This movement allows all sides of the pills to be fully exposed to the hot air, avoiding the problem of uneven heating of the pills and ensuring uniform drying. Furthermore, during the tumbling process, the internal moisture of the pills can diffuse more quickly to the surface. The friction and collision forces generated by the rotation destroy the moisture-saturated layer on the pills' surface, accelerating the migration of moisture from the interior to the exterior, thereby improving drying efficiency.

[0021] Optionally, the specific operation of heating to gel in step S2 is: first heating to 75-85° C., treating for 10-20 minutes, then cooling to 45-50° C., and adding Sn-2 DHA algae oil, arachidonic acid and N-acetylneuraminic acid.

[0022] Optionally, 0.5-1.5 parts of vitamin E succinate are added together with gelatin in step S2, and 0.1-0.5 parts of tea polyphenols are added together with Sn-2 DHA algae oil after cooling.

[0023] By adopting the above technical solution, since raw materials such as DHA algae oil, arachidonic acid and walnut oil all contain unsaturated fatty acids, the unsaturated double bonds in the molecular structure will undergo oxidation reactions to generate oxidation products that affect the flavor and taste, and reduce the biological activity and nutritional value of DHA.

[0024] Therefore, in this application, vitamin E succinate is added first at the same time as gelatin. With the film-forming effect of gelatin, an antioxidant layer is formed to wrap the DHA molecules and delay the oxidation chain reaction. It is added in the heating stage and integrated into the system in advance. Vitamin E succinate is relatively stable under heating conditions, maintains its antioxidant activity at high temperatures, and reduces oxidation during the heating process. The subsequent addition of tea polyphenols can provide hydrogen atoms to combine with free radicals to inactivate the free radicals, exert its antioxidant effect, and protect the added Sn-2 DHA algae oil and arachidonic acid. Moreover, the addition of tea polyphenols can regenerate vitamin E and restore its antioxidant activity. Specifically, after vitamin E donates hydrogen atoms to free radicals to inactivate the free radicals, it itself is converted into vitamin E free radicals. It has a certain reactivity and will react with other substances to gradually lose its antioxidant ability. Tea polyphenols can donate hydrogen atoms to vitamin E free radicals, so that vitamin E is restored to its original antioxidant active form. The presence of multiple phenolic hydroxyl groups in tea polyphenols can further stabilize the free radicals through intramolecular electron transfer, thereby terminating the free radical chain reaction.

[0025] Ultimately, tea polyphenols regenerate vitamin E in the process of forming an effective antioxidant cycle. Vitamin E preferentially reacts with free radicals in the lipid phase to exert its antioxidant effect. When vitamin E is oxidized to free radical form, tea polyphenols can promptly regenerate it, allowing vitamin E to continue to participate in the antioxidant reaction. This synergistic effect greatly enhances the antioxidant capacity of the entire system. Combined with the temperature gradient change in step S2, it provides continuous and effective antioxidant protection at different stages, which can more effectively protect the easily oxidized ingredients in the gel candy, such as Sn-2 DHA algae oil and Sn-2 arachidonic acid, from oxidation, thereby ensuring the quality and stability of the product and extending its shelf life.

[0026] Optionally, in step S2, the sweet orange oil is added after being microencapsulated, and the specific operation is as follows: Beta-cyclodextrin is dissolved in water and heated to 45-55° C. to prepare a beta-cyclodextrin solution. Sweet orange oil and Tween are added to the beta-cyclodextrin solution, stirred and homogenized, and then spray-dried to prepare microencapsulated sweet orange oil.

[0027] By adopting the above technical solution, sweet orange oil contains a variety of antioxidant ingredients such as limonene. After being microencapsulated, the limonene and vitamin C in the sweet orange oil can be protected from high-temperature damage, while extending the release cycle of the antioxidant ingredients. This can continuously clear free radicals in the system, help protect the stability and activity of ingredients such as DHA algae oil, and improve antioxidant properties. On the other hand, after the microencapsulation treatment and sustained release, the aroma of the sweet orange oil can be continuously released for a longer time, thereby improving the flavor persistence of the product.

[0028] Optionally, during the orange oil microcapsule treatment, the mass ratio of β-cyclodextrin to orange oil is 1:(0.1-0.2), the mass ratio of β-cyclodextrin to water is 1:(8-10), and the amount of Tween added is 1-3wt% of the orange oil.

[0029] Optionally, when treating the sweet orange oil microcapsules, Tween is added and stirred at a speed of 1000-1800 r / min for 10-20 minutes, and then homogenized 2-3 times at a homogenization pressure of 10-20 MPa.

[0030] In summary, this application has the following beneficial effects: 1. This application uses Sn-2 DHA algae oil as the main ingredient, combined with other auxiliary materials, to make it into a gel candy, which improves its taste and makes the ingestion method more convenient. The gel candy has a good taste and smell, is particularly suitable for children to eat, and improves compliance; 2. Walnut oil in this application is rich in Omega-3 fatty acids, which help improve the absorption rate of DHA and promote brain development; Sn-2 arachidonic acid and DHA work synergistically to promote brain development and functional improvement; N-acetylneuraminic acid (sialic acid) plays an important role in the development of the brain and nervous system, can improve malnutrition, and promote the normal development of brain function in infants and young children; 3. In the present application, vitamin E succinate is first added while adding gelatin. With the film-forming effect of gelatin, an antioxidant layer is formed to wrap the DHA molecules and delay the oxidation chain reaction. It is added in advance into the system during the heating stage. Vitamin E succinate is relatively stable under heating conditions, maintains its antioxidant activity at high temperatures, and reduces oxidation during the heating process. The subsequent addition of tea polyphenols can provide hydrogen atoms to combine with free radicals to inactivate the free radicals, thereby exerting their antioxidant effect and protecting the added Sn-2 DHA algae oil and arachidonic acid. Moreover, the addition of tea polyphenols can regenerate vitamin E and restore its antioxidant activity. An effective antioxidant cycle is formed during the regeneration of vitamin E by tea polyphenols. This synergistic effect greatly enhances the antioxidant capacity of the entire system. Combined with the temperature gradient change in step S2, continuous and effective antioxidant protection is provided at different stages, which can more effectively protect the easily oxidized components in the gel candy, such as Sn-2 DHA algae oil, Sn-2 arachidonic acid, etc., to prevent them from being oxidized, thereby ensuring the quality and stability of the product and extending the shelf life of the product.

[0042] Example 10 A method for preparing Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development is carried out according to the method in Example 4, except that the sweet orange oil in step S2 is added after microencapsulation. The specific operations are as follows: β-cyclodextrin was dissolved in 8 times the mass of water and heated to 45°C to prepare a β-cyclodextrin solution.

[0044] Comparative Example 1 A method for preparing Sn-2 DHA algae oil gel candy with high absorption rate and promoting brain development is carried out according to the method in Example 1, except that sweet orange oil is not added to the raw materials.

[0045] Performance testing The Sn-2 DHA algae oil gel candies prepared in the examples and comparative examples of the present application were first subjected to an initial peroxide value (POV) test to evaluate the degree of oxidation during the preparation process. In addition, the peroxide value (POV) (meq / kg) was tested after an accelerated oxidation test (40°C / 75% RH, 72 hours). The test results are shown in Table 1 below.

[0046] Table 1: Referring to the test results in Table 1 above, it can be seen that the initial peroxide value of the Sn-2 DHA algae oil gel candy prepared in the embodiment of the present application is low, and its degree of oxidation during the preparation process is low. Combined with the test results of Example 1 and Example 4, when vitamin E succinate and tea polyphenols are added during the preparation process in Example 4, the oxidation of oil can be effectively inhibited. Combined with the test results in Example 7 and Example 8, when only vitamin E succinate is added in Example 7, its peroxide value is improved, especially after the accelerated oxidation test, its peroxide value is significantly improved. When only vitamin E succinate is added, it gradually loses its antioxidant properties after donating electrons in the later stage. Combined with the test results of Example 8, when only tea polyphenols are added, although it has certain antioxidant properties, compared with Example 4, the tea polyphenols in Example 4 can achieve the regeneration of vitamin E succinate, and the combination of the two can achieve a more lasting and effective antioxidant effect.

[0047] Combined with the test results of Examples 9-11, when the sweet orange oil is added after microencapsulation, the initial antioxidant value of the obtained product is further reduced, and the antioxidant value after accelerated oxidation test is also lower, which shows that the sweet orange oil microencapsulation treatment helps to improve the sustained antioxidant performance of the product. Referring again to the test results in Comparative Example 1, when sweet orange oil is not added to the raw material, it is partially oxidized during processing, and its antioxidant capacity is weak. Adding vitamin E succinate and tea polyphenols and carrying out sweet orange oil microencapsulation treatment in the present application can significantly improve the antioxidant performance of Sn-2 DHA algae oil gel candy, effectively inhibiting the oxidation of DHA and arachidonic acid, thereby maintaining the quality and stability of the product. In particular, the sweet orange oil microencapsulation treatment not only protects the antioxidant components in the sweet orange oil, but also extends its release cycle, further improving the antioxidant performance and flavor persistence of the product.

[0048] In addition, the sensory evaluation results shown in Table 2 below were performed on the 2DHA algae oil gel candies prepared in the examples of the present application.

[0049] Table 2: In this application, Sn-2 DHA algae oil is used as the main ingredient, combined with other auxiliary materials, and made into a gel candy form to improve its taste and make the intake method more convenient. The gel candy has a good taste and smell, is particularly suitable for children to eat, and improves compliance.
