Therefore, the content of active ingredients in the schisandra chinensis powder fermentation broth is obviously higher than that of the schisandra chinensis whole grain fermentation broth. Therefore, the schisandra chinensis is fermented after being crushed and passing through 20 meshes.
The fermentation process conditions of the distiller's yeast are optimized:

Table 1 L9(34)Orthogonal test results
As can be seen from Table 1, the primary and secondary order of the factors under each index can be listed according to the R value of the range. The influence of each factor on the content of schisantherin A is the inoculation quantity (A)>Time (D)>Temperature (B)>The ratio of material to liquid (C). The sequence of the influence of each factor on the deoxyschizandrin content is time (D)>Bacterial quantity (A)>Temperature (B)>The ratio of material to liquid (C). Each factor is to the flavone contentThe order of influence is temperature (B)>Time (D)>Bacterial quantity (A)>The ratio of material to liquid (C). And determining the optimized level combination of each factor according to the average values of different levels of each index. The best combination taking schisantherin A as an index is A3B1C3D3The best combination taking deoxyschizandrin as an index is A3B1C1D3The best combination taking flavone as an index is A2B1C3D3。
The optimization conditions analyzed by the three indexes independently are inconsistent, so that the optimal process conditions are determined by adopting a comprehensive balance method according to the primary and secondary influence of factors. For inoculum size a: the influence on the content of schisantherin A is ranked first, and A is taken at the moment3(ii) a For schisandrin, take A3Is the optimum level; the influence on the flavone content is ranked in the third place and is a secondary factor, therefore, the inoculation amount is selected from A3. For temperature B: get B horizontally1The contents of schisantherin A, deoxyschizandrin and flavone are highest, so that B is taken1. For the feed-liquid ratio C: the influence on the contents of schisantherin A, deoxyschizandrin and flavone is in the fourth place, and is a secondary factor, so C can be selected1And C3But consider in C3The contents of schisantherin A and flavone are highest horizontally, so taking C3. For time D: horizontal fetching D3The contents of schisantherin A, deoxyschizandrin and flavone are highest, so that D is taken3. In summary, the best experimental protocol is A3B1C3D3. Namely, the inoculation amount is 0.7 percent, the fermentation temperature is 30 ℃, the ratio of material to liquid is 1:15, and the fermentation time is 48 hours. At this time, the content of schisantherin A is 1.8313 μ g/mL, the content of deoxyschizandrin is 3.6881 μ g/mL, and the content of flavone is 0.0239 μ g/mL. While the content of schisantherin A in the unfermented schisandra chinensis soak solution is 0.5471 mug/mL, the content of deoxyschizandrin is 0.5539 mug/mL, and the content of flavone is 0.0232 mug/mL.
Optimization of soaking process conditions of coreopsis tinctoria
Mixing Kunlun snow chrysanthemum: water, soaking time and soaking times are used as investigation factors, and the actual material-liquid ratio and soaking of the materials are combined with the preliminary test and the productionThe soaking time was 6 levels per factor and the soaking times were 3 levels. Obtaining a mixed level uniform design table U by adopting a quasi-level method6(62X 3), taking the content of the flavone in the soaking solution as an evaluation index, and the test scheme and the result are shown in table 2:
TABLE 2U6(62X 3) homogeneous test design and results
Table 2 U6(62×3)Uniform design matrix and experimental results
According to the design of a uniform test, under the conditions that the material-liquid ratio is 1:90, the soaking time is 1h, and the soaking time is 1 time, the content of flavone is 2.214 mu g/mL, and the content is the highest.
Mixing principle of fructus Schisandrae fermentation liquid and coreopsis tinctoria soaking liquid
The addition of 3-9g of schisandra chinensis according to the recommended daily intake of a human body achieves the effects of maintaining beauty, keeping young and improving sleep, and 1-2 g of chrysanthemum morifolium ramat is brewed every day, so that the effect of treating frequent insomnia is better. Therefore, the active ingredient content in the finally prepared granules can reach the amount of the active ingredient contained in the daily intake of the schisandra chinensis and the snow chrysanthemum.
The acidic component in the schisandra chinensis is high, and if the concentration of the snow chrysanthemum soaking solution is too high, the taste is bitter, and people cannot eat the snow chrysanthemum soaking solution easily, so that the acidity and the bitter taste can be reduced when the snow chrysanthemum soaking solution and the snow chrysanthemum soaking solution are combined. The schisandra chinensis fermentation liquor and the coreopsis tinctoria soaking solution are mixed according to equal proportion.
Auxiliary material screening and proportioning optimization
Lactose, sucrose, maltodextrin, cyclodextrin, dietary fiber and soluble starch are taken as excipients respectively, and granules are prepared according to the preparation process and the operational points. The sensory state of the granules was described, and then evaluated by hygroscopicity, moldability, angle of repose, solubility, and bulk density. And comprehensively evaluating formability, bulk density, angle of repose, dissolubility and hygroscopicity as indexes, and screening the types of auxiliary materials.
The overall index = (20/maximum moldability value) × moldability value + (15/maximum bulk density value) × bulk density value + (minimum angle of repose value × 15)/angle of repose value + (25/maximum solubility value) × solubility value + (minimum moisture absorption value × 25)/moisture absorption value +(minimum moisture absorption value × 25)/moisture absorption value
The results in fig. 5 show that lactose can be formed, has consistent color, uniform particles, no agglomeration and fine powder, sour, astringent and no off-flavor. The soluble starch can be formed, has consistent color and luster, uniform granules, fine powder, sour and astringent taste and slight peculiar smell. The cyclodextrin has the advantages of uniform color, uniform granules, no agglomeration or fine powder, sour and astringent taste, and no odor. The sucrose can be molded, the color is consistent, and the particles are non-uniform in adhesion. Sour and astringent, no peculiar smell, no possibility of forming maltodextrin, consistent color, agglomeration of particles, sour and astringent taste and no peculiar smell. The dietary fiber can not be formed, has consistent color and luster, particles are agglomerated, and has sour and astringent taste and no peculiar smell. Maltodextrin and dietary fibers are not sticky and not suitable for being used as auxiliary materials for preparing granules, so the two auxiliary materials are excluded in the subsequent screening.
As is clear from FIG. 6, the moldability of lactose and cyclodextrin was good. Bulk density, also known as apparent density or bulk density, refers to the mass of a particle per unit volume. The bulk density is defined as that the granules and the gaps between the granules are large in the bulk density of the granules, namely the bulk volume is small, namely the single-dose volume is small, and the bulk density of sucrose is maximum, so that the sucrose has certain advantages in the granule processing process. The flowability is one of important properties of granules, the quality of the flowability is related to the quality of the granules and the accuracy of divided dose, and the smaller the angle of repose, the better the flowability is, the more commonly expressed in terms of flow rate and angle of repose in pharmaceutics. Generally, the smaller the particle size or the wider the particle size distribution, the larger the angle of repose; the granules with round, large and uniform particle size are easy to flow, the angle of repose is small, and the angle of repose of lactose is minimum, which indicates that the quality of lactose granulation is high. Hygroscopicity is an important index reflecting the quality of granules, and the moisture absorption rate of cyclodextrin and sucrose is relatively low. Lactose and sucrose have the best solubility, and cyclodextrin and soluble starch have poor solubility. The combined sucrose and lactose scores were highest according to the combined analysis of Table 8. However, lactose is relatively fragile and easy to absorb moisture, sucrose is not easy to form, but the hardness of the granules is better, so in order to make up for the advantages and disadvantages of the lactose and the sucrose, the lactose and the sucrose are jointly used as auxiliary materials for granulation.

According to fig. 7, with lactose: sucrose becomes larger gradually, the particle state and the formability become better gradually, the particle hardness is large when the sucrose proportion is larger, the particle forming effect is better when the lactose proportion is larger, but the particle effect is softer when more lactose is added, and the phenomenon of lactose intolerance can also occur after the human body eats the lactose-containing food. Lactose was therefore selected from a combination of mouthfeel and formability: the optimal ratio of sucrose is 7: 1.
Low temperature drying condition optimization
Concentrating the schisandra chinensis snow chrysanthemum concentrate: auxiliary materials, drying temperature and drying time are used as investigation factors, and each factor is taken as 7 levels by combining with a pre-test. Design uniformity test U7(73) The test protocol and results are shown in Table 3 and FIG. 19, using hygroscopicity and moldability as evaluation indices:

Table 4 U7(73)Uniform design matrix and experimental results
As can be seen from table 3, the concentrate: when the auxiliary material preparation ratio is smaller, the granulation formability is better and reaches more than 85%, the more auxiliary materials are, the stronger the hygroscopicity of the granules is, the comprehensive consideration is given, and the group 6 is selected as the best combination, namely the concentrated solution: the auxiliary materials are 35:6, the drying temperature is 55 ℃, and the drying time is 4 h.
