Description

Technical Field

[0001] The invention belongs to the technical field of food, and particularly relates to American ginseng Yuling paste and a preparation method thereof. Background Art

[0002] Yuling Paste is an ancient Chinese medicine dietary recipe, originating from the Suixiju Dietary Guide by renowned Qing Dynasty physician Wang Mengying. Its main ingredients are longan and American ginseng. Longan and American ginseng are known for their ability to tonify qi and blood, offering excellent tonic benefits. Wang Mengying, a Qing Dynasty physician, dubbed it "Substitute Ginseng Paste." It possesses valuable benefits for the human body, with its primary function being to tonify blood and qi.

[0003] The traditional preparation of Yuling Paste involves washing longan and mixing it with American ginseng powder in a 10:1 ratio. The mixture is then placed in a stewing pot and steamed for 40 hours, allowing the longan's heat to dissipate and the paste to become milder. This traditional preparation method is relatively simple and straightforward, preserving the nutritional value of both American ginseng and longan to a certain extent.

[0004] However, existing preparation technologies have many defects. First, direct steaming makes it difficult to fully release the active ingredients of American ginseng and longan; the cell wall structure of American ginseng is relatively dense, and the nutrients in longan meat are also wrapped in a complex cell system. Simple steaming cannot fully dissolve the active ingredients in the cells, resulting in the nutritional value of the product not being fully realized. Secondly, the taste of Yuling Paste is single. After simple mixing and steaming, the texture of the product is relatively single and the taste is not rich enough, which makes it difficult to meet consumers' demand for both deliciousness and nutrition. Furthermore, from the perspective of production efficiency, the long steaming process consumes a lot of energy and time, increases production costs, and is not conducive to large-scale industrial production.

[0005] Therefore, developing a preparation method for American ginseng Yuling paste with simple process, while ensuring that the effective ingredients of American ginseng Yuling paste are effectively utilized, improving the utilization rate of raw materials, reducing the generation of industrial waste, and improving the product taste has become one of the technical problems that need to be solved urgently. Summary of the Invention

[0006] In response to the shortcomings of the prior art, the present invention aims to provide an American ginseng Yuling paste and a preparation method thereof. The preparation method of the present invention improves the product yield, maximizes resource utilization, and reduces the generation of industrial waste. Furthermore, the prepared American ginseng Yuling paste has a rich taste and contains a high content of effective ingredients.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a method for preparing American ginseng Yuling paste, the preparation method comprising the following steps:

[0009] (1) Longan, American ginseng and an aqueous solution of a complex enzyme are mixed and subjected to enzymatic hydrolysis to obtain a pretreated product.

[0010] (2) decocting the pretreated product obtained in step (1), filtering and separating the filtrate and the filter residue; mixing and soaking the filter residue with water at least once and then decocting the filter residue, and filtering and separating the filtrate and the filter residue after each decocting.

[0011] (3) combining, chopping, and dehydrating the filter residues obtained from each decoction step in step (2); combining and concentrating the filtrates obtained from each decoction step in step (2) to obtain a concentrated solution.

[0012] (4) The concentrated solution obtained in step (3) is mixed with the dehydrated filter residue to obtain American ginseng Yuling paste.

[0013] The at least one time in step (2) can be selected 1 time, 2 times, 3 times, 4 times, 5 times or 6 times, etc., preferably 1-3 times.

[0014] During the preparation process of the American ginseng Yuling paste, the present invention performs a backfilling treatment on the filter residue. Compared with the method of directly discarding the precipitate in the traditional process, the method maximizes the utilization of raw material resources. More importantly, the method greatly enriches the taste of the American ginseng Yuling paste, increases the content of effective ingredients such as dietary fiber, vitamin B6, and polysaccharides, and improves the edibility of the product.

[0015] At the same time, after decocting the pretreated product obtained by the enzymatic hydrolysis reaction, the filter residue is decocted again, and the filtrates of the multiple decoctions are combined, so that the taste of the prepared product can be more delicate and rich.

[0016] Preferably, the mass ratio of longan and American ginseng in step (1) is 10:1-20:1, for example, it can be 10:1, 12:1, 14:1, 16:1, 18:1, 20:1, etc.

[0017] Preferably, the ratio of the total mass of the longan and American ginseng in step (1) to the volume of the aqueous solution of the complex enzyme is 1:4-1:6 g / mL, for example, it can be 1:4 g / mL, 1:4.5 g / mL, 1:5 g / mL, 1:5.5 g / mL, 1:6 g / mL, etc.

[0018] Preferably, the complex enzyme in step (1) comprises α-arabinosidase, β-glucosidase and β-xylosidase.

[0019] α-arabinosidase can specifically hydrolyze carbohydrates containing α-L-arabinofuranoside bonds to release arabinose residues, β-glucosidase can catalyze the hydrolysis of compounds containing β-D-glucosidic bonds to release glucose, and β-xylosidase can hydrolyze oligosaccharides containing β-D-xylosidic bonds to release xylose. The present invention creatively discovered that α-arabinosidase, β-glucosidase, and β-xylosidase have significant synergistic effects in the enzymatic hydrolysis of longan and American ginseng. The combination of the above three enzymes can further degrade the components in the raw materials, such as the decomposition of large molecular ginsenosides (Re, Rg, Rb1, Rc, Rb2, Rd), and the significant increase in the content of small molecular ginsenoside Rh1 and rare saponin Compound K, which is more conducive to human absorption and utilization. At the same time, the prepared product has an excellent taste level.

[0020] Preferably, the mass ratio of the α-arabinosidase, β-glucosidase and β-xylosidase is (1-3):(1-3):(1-3).

[0025] Preferably, the decocting time of the pretreated material obtained in step (1) in step (2) is 1.5-2.5 h, for example, 1.5 h, 1.7 h, 1.9 h, 2.1 h, 2.3 h, 2.5 h, etc.

[0026] The present invention creatively discovered that controlling the decocting time to 1.5-2.5 hours can further improve the eating experience of the product, stabilize the product state, and increase the content of the effective ingredients in the product.

[0027] Preferably, in step (2), after being mixed with water and soaked at least once and then decocted, the mass volume ratio of the filter residue to water during each soaking is 1:4-1:6 g / mL, for example, it can be 1:4 g / mL, 1:4.5 g / mL, 1:5 g / mL, 1:5.5 g / mL, 1:6 g / mL, etc.

[0028] The present invention creatively discovered that controlling the mass volume ratio of filter residue to water at 1:4-1:6 g / mL can fully release the active ingredients in the raw materials, thereby improving the edible experience of the product and stabilizing the product state.

[0029] Preferably, in step (2), the decoction is performed after being mixed with water and soaked at least once, and the decoction time for each decoction is 1.5-2.5 hours, for example, 1.5 hours, 1.7 hours, 1.9 hours, 2.1 hours, 2.3 hours, 2.5 hours, etc.

[0031] Preferably, the concentration in step (3) includes primary concentration and secondary concentration performed sequentially.

[0032] The primary concentration is to concentrate the filtrate to a liquid density of 1.1-1.2 g / cm 3 , pass through a 180-220 mesh sieve to obtain the primary concentrated solution.

[0033] The secondary concentration is to concentrate the primary concentrated liquid to a liquid density of 1.3-1.4 g / cm 3 , pass through an 80-120 mesh sieve to obtain a concentrated solution.

[0034] Among them, 1.1-1.2g / cm 3 The specific point value can be selected as 1.1g / cm 3 , 1.12g / cm 3 , 1.14g / cm 3 , 1.16g / cm 3 , 1.18g / cm 3 , 1.2g / cm 3 etc., 1.3-1.4 g / cm 3 The specific point value can be selected as 1.3g / cm 3 , 1.32g / cm 3 , 1.34g / cm 3 , 1.36g / cm 3 , 1.38g / cm 3 , 1.4g / cm 3 Etc., the specific point values ​​in 180-220 mesh can be selected from 180 mesh, 190 mesh, 200 mesh, 210 mesh, 220 mesh, etc., the specific point values ​​in 80-120 mesh can be selected from 80 mesh, 90 mesh, 100 mesh, 110 mesh, 120 mesh, etc.

[0035] Preferably, the process of mixing the concentrated liquid and the dehydrated filter residue in step (4) also includes mixing with honey.

[0036] Preferably, the mass percentage of honey in the American ginseng Yuling paste is 35-40%, for example, it can be 35%, 36%, 37%, 38%, 39%, 40%, etc.

[0037] In a second aspect, the present invention provides an American ginseng Yuling paste prepared by the preparation method of the American ginseng Yuling paste described in the first aspect.

[0038] The numerical range described in the present invention includes not only the point values ​​listed above, but also any point values ​​between the above numerical ranges that are not listed. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] During the preparation process of the American ginseng Yuling paste, the present invention performs backfilling treatment on the filter residue. Compared with the method of directly discarding the precipitate in the traditional process, the present invention achieves maximum resource utilization. More importantly, the present invention greatly enriches the taste of the American ginseng Yuling paste and the content of effective ingredients such as dietary fiber, vitamin B6, and polysaccharides, thereby improving the edibility of the product.

[0041] Furthermore, after decocting the pretreated product obtained by the enzymatic hydrolysis reaction, re-decocting the filter residue and combining the filtrates from multiple decoctions can make the prepared product more delicate and rich in taste. Furthermore, controlling the number of re-decoctings to 1-3 times can further improve the edible experience and the content of the active ingredients in the product.

[0042] Furthermore, in the process of enzymatic hydrolysis of longan and American ginseng, α-arabinosidase, β-glucosidase and β-xylosidase have significant synergistic effects. The combined use of the above three enzymes can further degrade the components in the raw materials. For example, large molecular ginsenosides (Re, Rg, Rb1, Rc, Rb2, Rd) are decomposed, and the content of small molecular ginsenoside Rh1 and rare saponin Compound K is significantly increased, which is more conducive to human absorption and utilization, and at the same time makes the prepared product have an excellent taste level.

[0043] Furthermore, during the soaking process of the longan and American ginseng raw materials or filter residues, the material-liquid ratio of the raw materials to water is controlled at 1:4-1:6 g / mL, which can fully release the active ingredients in the raw materials, thereby improving the edible experience of the product and stabilizing the product state.

[0044] Furthermore, during the decoction process, controlling the decoction time to 1.5-2.5 hours can further improve the eating experience of the product, stabilize the product state, and increase the content of the effective ingredients in the product.

[0045] Furthermore, in the preparation process of American ginseng Yuling paste, adding honey can enrich the smell of the product while improving the taste and state of the product. DETAILED DESCRIPTION

[0094] (1) Evaluation method:

[0095] 75 evaluators were selected and divided into 15 groups, with 5 people in each group. The evaluators in each group consumed an equal amount of the American ginseng Yuling paste prepared in the above embodiments and comparative examples.

[0096] The evaluators are required to evaluate the American ginseng Yuling paste prepared in the above-mentioned embodiments and comparative examples in an environment with sufficient light and no odor interference. They should rinse their mouths with clean water before evaluation to keep their senses sensitive. The evaluators should evaluate the American ginseng Yuling paste from five aspects: smell (full score 20 points), taste (full score 30 points), color (full score 20 points), consistency (full score 20 points) and tissue state (full score 10 points). The scores of the smell, taste, color, consistency and tissue state are the average scores of each group of evaluators; the sum of the scores of the five indicators is calculated, and the final score reflects the sensory quality level of the American ginseng Yuling paste.

[0112] (3) Sensory evaluation results:

[0113] The sensory evaluation results of the American ginseng Yuling paste prepared in each embodiment and comparative example are shown in Table 7.

[0114] Table 7

[0115]

[0116]

[0117] It can be seen from the data in Table 7 that the American ginseng Yuling paste prepared by the present invention has a pure aroma, a delicate taste, a mellow taste, a uniform color, good gloss, a dark brown or reddish brown color, a moderate consistency, good ductility and adhesion, and a fine and tight paste texture.

[0118] From the comparison of the data of Example 1 and Comparative Example 1, it can be seen that in the preparation process of American ginseng Yuling paste, backfilling treatment of the filter residue greatly enriches the taste of the American ginseng Yuling paste and improves the edibility of the product.

[0119] From the comparison of the data of Example 1 with Comparative Example 3 and Example 11, it can be seen that after decocting the pretreated material obtained by the enzymatic hydrolysis reaction, the filter residue is decocted again, and the filtrate from multiple decoctions is combined, the taste of the prepared product can be made more delicate and the smell richer; at the same time, controlling the number of re-decocting times to 1-3 times can further improve the eating experience and appearance of the product.

[0120] From the comparison of the data of Example 1 and Examples 4-5, it can be seen that in the process of soaking the longan and American ginseng raw materials or filter residues, the material-liquid ratio of the raw materials to water is controlled at 1:4-1:6 g / mL, which can fully release the active ingredients in the raw materials, thereby improving the edible experience of the product and stabilizing the product state.

[0121] From the comparison of the data of Example 1 with Comparative Example 2 and Examples 6-8, it can be seen that before decocting the longan and American ginseng, the longan and American ginseng raw materials are enzymatically hydrolyzed, which can better decompose macromolecular dietary fiber, polysaccharides, ginsenosides and other substances, thereby improving the eating experience of the product; in addition, α-arabinosidase, β-glucosidase and β-xylosidase have significant synergistic effects in the process of enzymatic hydrolysis of longan and American ginseng. The above three enzymes are used in combination to further degrade the macromolecular ginsenosides in the raw materials, increase the content of small molecular ginsenoside Rh1 and rare saponin Compound K, and are more conducive to human absorption; and after enzymatic hydrolysis, the bitterness of American ginseng is reduced, and the sweet flavor of longan and honey is released to a greater extent, so the sensory tasting score is significantly improved, and the prepared product has a more excellent taste level.

[0122] From the comparison of the data of Example 1 and Examples 9-10, it can be seen that controlling the decoction time for each time to 1.5-2.5 hours can further improve the eating experience of the product and stabilize the product state.

[0123] From the comparison of the data of Example 1 and Example 12, it can be seen that the honey in the American ginseng Yuling paste can enrich the smell of the product and improve the taste and state of the product.

[0124] Test Example 2

[0125] This test example evaluates the content of effective ingredients in American ginseng Yuling Paste.

[0126] (1) Evaluation indicators:

[0127] Total solid content, dietary fiber content, vitamin B6 content, polysaccharide content, paste yield, raw material utilization rate, ginsenoside Re, Rg, Rb1, Rc, Rb2, Rd content, rare saponin Compound K content, ginsenoside Rh1 content.

[0128] The total solids, dietary fiber, vitamin B6, and polysaccharide contents indicate the amount of effective ingredients dissolved in the raw materials. The higher the content, the better the dissolution effect. The paste yield and raw material utilization rate indicate the degree of material utilization. The higher the value, the higher the degree of material utilization. Ginsenosides Re, Rg, Rb1, Rc, Rb2, and Rd are the combined contents of effective ingredients dissolved in the raw materials and their decomposition degree. Rare saponins Compound K and ginsenoside Rh1 are obtained by the decomposition of macromolecular saponins. The higher their content, the more degraded the ginsenosides are, and they are easier to be absorbed and utilized by the human body.

[0129] (2) Evaluation method:

[0130] The total solids shall be tested according to the first method of GB 5009.3-2016; the dietary fiber shall be tested according to the third method of GB 5009.88-20236.4; the vitamin B6 shall be tested according to the third method of GB 5009.154-2023; the polysaccharides shall be tested according to SN / T4260-2015; the paste yield = (mass of finished paste / total mass of medicinal materials and excipients) × 100%; the raw material utilization rate = (mass of solids / mass of raw materials) × 100%; the content of ginsenosides Re, Rg, Rb1, Rc, Rb2, Rd, Compound K, and Rh1 shall be tested according to the second part of the Technical Guidelines for Inspection and Evaluation of Physical, Chemical and Hygienic Indicators of Health Foods (2020 Edition).

[0131] (3) Evaluation results:

[0132] The results of the determination of the contents of the effective ingredients of the American ginseng Yuling paste prepared in the examples and comparative examples are shown in Tables 8 and 9.

[0136]

[0137]

[0138] From the comparison of the data of Example 1 and Comparative Example 1, it can be seen that in the preparation process of American ginseng Yuling paste, backfilling the filter residue can significantly increase the content of total solids, dietary fiber, vitamin B6, and polysaccharides, effectively improve the paste yield and raw material utilization rate of the finished product, improve the nutritional value and output value of the finished product, and reduce the generation of industrial waste.

[0139] From the comparison of the data of Example 1 with Comparative Example 3 and Example 11, it can be seen that after decocting the pretreated material obtained by the enzymatic hydrolysis reaction, the filter residue is decocted again, and the filtrate of multiple decoctions is combined, which can significantly increase the content of total solids, dietary fiber, vitamin B6, and polysaccharides, and effectively improve the paste yield and raw material utilization rate of the finished product; at the same time, controlling the number of re-decoctions to 1-3 times can more fully increase the content of the effective ingredients while saving production costs.

[0140] From the comparison of the data of Example 1 and Example 4-5, it can be seen that in the process of soaking the longan and American ginseng raw materials or filter residues, the dietary fiber, vitamin B6, total polysaccharide content and raw material utilization rate can be improved. At the same time, the material-liquid ratio of the raw material to water is controlled at 1:4-1:6 g / mL, which can not only promote the diffusion of water-soluble dietary fiber from the medicinal material cells to the solvent and increase the dietary fiber content, but also obtain better sensory evaluation results (which can improve the edible experience of the product and stabilize the product state).

[0141] Comparison of the data in Example 1 with Comparative Example 2 and Examples 6-8 shows that the enzymatic hydrolysis reaction can better retain the effective components of longan and American ginseng, making the product more easily usable by the human body with a higher content of small molecules. In addition, α-arabinosidase, β-glucosidase, and β-xylosidase have a significant synergistic effect in the enzymatic hydrolysis of longan and American ginseng. The combination of the three enzymes can further degrade the components in the raw materials, and the ginsenosides (Re, Rb1, Rc, Rb2, Rd) are degraded to a greater extent to obtain a higher content of small molecule ginsenoside Rh1 and rare saponin Compound K.

[0142] From the comparison of the data of Example 1 and Examples 9-10, it can be seen that controlling the decoction time for each time to 1.5-2.5h can increase the dietary fiber, vitamin B6, polysaccharide content, paste yield and raw material utilization rate, but after exceeding 2.5h, some heat-sensitive unstable components are destroyed, and the content of the above components, paste yield and raw material utilization rate basically no longer increase or decrease; combined with the sensory evaluation results, the decoction time for each time is controlled at 1.5-2.5h.

[0143] From the comparison of the data of Example 1 and Example 12, it can be seen that the addition of honey to the American ginseng Yuling paste can increase the polysaccharide content and improve the product's edible experience and state stability.
