Rhizoma Polygonati Odorati is a perennial herb of Liliaceae, has effects of nourishing yin, moistening dryness, clearing heat, promoting fluid production, relieving cough, etc., is commonly used as tonic medicine, is mainly used for treating diseases such as yin injury due to heat disease, cough due to deficiency heat, heart disease, diabetes, tuberculosis, etc., and can be used as high-grade tonic food, food and beverage, and has health promotion effect. Rhizoma polygonati is used as a medicine and food homologous substance and has a plurality of effects after being eaten for a long time, but because the raw product is chewed and sticky, the raw product is used for piercing the throat, but is less frequently eaten directly, and is generally used as a raw material of a traditional Chinese medicine and food formula for decocting the tonic soup. The process of boiling the nourishing soup is complicated, the time is long, the taste is poor, and the control is difficult for a common person according to various precautions such as decoction before decoction, package decoction and the like. Moreover, the eating is inconvenient, and the enthusiasm of people for the polygonatum odoratum to eat is reduced to a great extent, so that the efficacy of the polygonatum odoratum is difficult to be exerted. Therefore, development of a fragrant solomonseal rhizome product which is convenient to eat and has excellent effect is needed.
The slow food is a cooking method, which is to put tough food into a wok (pot), add a proper amount of soup, and cook soft and ripe food with slow fire. The cooking technology of the processing technology with multiple taking methods has become a unique special method for specially processing the nourishing medicinal materials nowadays, namely soaking the clean medicinal materials in water, then putting the soaked medicinal materials into a ceramic braised drug jar, adding clear water and auxiliary materials, putting the mixture into bran fire, and slowly stewing with slow fire until the mixture is cooked, thus belonging to a water-fire common method. The method is different from the iron pot boiling method and the water-stop stewing method, and is also different from the method of directly placing the medicinal materials in bran fire for dry stewing, but takes a ceramic pot as a container, and adds water for slow boiling. The pottery is used for cooking food, so that the prepared food not only maintains the original taste and flavor, but also has fragrant and mellow taste, and is still known by people until now, and the pottery braiss are used for preparing nourishing medicinal materials, so that the nourishing medicinal materials have pure and thick smell but not greasy, have strong nourishing power, and reduce the side effects. However, no related braised products and braised processing technology of radix polygonati officinalis are reported at present, and the traditional braised processing technology of medicinal materials adopts a bran fire heating method, so that potential safety hazards exist, and the quality is not easy to control.

Test animals: male rats, at the end of the adaptation period (5-7 days of feeding maintenance feed to rats under the barrier system), had a body weight of 200.+ -.20 g,200 animals.
And (3) molding: after the adaptation period, the animals were randomly divided into 2 groups according to body weight, 10 rats were given maintenance feed as a blank group, and 190 rats were given high calorie model feed. The feeding amount, the sprinkling amount and the remaining amount were recorded weekly, and the body weight was weighed 1 time. After 2 weeks of feeding, 190 rats given high calorie diet were ranked in order of weight gain, and about 1/3 of obese resistant rats with lower weight gain were eliminated. The screened 140 obese susceptible rats were given high caloric feed for another 6 weeks, with a placebo group given maintenance feed.
Sample administration: after the modeling period is finished, 140 obese sensitive rats are randomly divided into 14 groups according to body weight, one group is used as a model control group, the feeding amount, the food scattering amount and the food remaining amount are recorded every week, and the body weight is weighed 1 time. The model control group and the test sample group were given high calorie model feed, and the blank control group was given maintenance feed. Each test sample group was given 1g/kg/d of the test sample of the different examples and comparative examples by gavage, and the model control group and the blank control group were given the same amount of the corresponding solvent for 6 weeks, not more than 10 weeks.
After the test, the body weight was weighed, 1% sodium pentobarbital (0.5 mL/100g BW) was anesthetized, perirenal fat was dissected from the testis, and the testis was weighed to calculate the fat/body ratio. The observation indexes include body weight, weight gain, food intake, food utilization (weight gain/food intake), fat weight in vivo (testis and perirenal fat pad), fat/body weight. The weight or weight gain of the experimental group is lower than that of the model control group, the fat weight or fat/body ratio in the body is lower than that of the model control group, the difference is significant, the ingestion is not significantly lower than that of the model control group, the animal weight-losing function experimental result of the tested sample can be judged to be positive, and the experimental result is counted in the table 2.

Figure BDA0002446202030000111
( And (3) injection: comparison with model control group: p < 0.05, compared to the blank #: p is less than 0.01 )
As can be seen from Table 3, the lipid oxidation product content, the protein carbonyl content, the antioxidant enzyme activity and the reduced glutathione content were significantly increased/decreased (P < 0.01) in the model control group compared with the blank control group, and the molding was successful. The mice eating the braised polygonatum food in the embodiments 1-2 of the invention have 3 indexes of positive indexes of lipid oxidation product content, protein carbonyl content, antioxidase activity and reducing glutathione content, and the mice eating the braised polygonatum food in the embodiments 3-7 of the invention have positive indexes of lipid oxidation product content, protein carbonyl content, antioxidase activity and reducing glutathione content, which indicates that the embodiments of the invention have antioxidative effect, and the effects of the braised polygonatum food in the embodiments 3-7 are better. And the mice eating the polygonatum food prepared by the technical scheme outside the protection scope of the invention have the best effect, and the comparative example 3 only has 2 indexes positive. Compared with the polygonatum food prepared by other technical schemes, the instant braised polygonatum food prepared by the technical scheme has good oxidation resistance.
4. The invention relates to an auxiliary blood lipid reducing effect test for instant braised fragrant solomonseal rhizome food
The test method comprises the following steps: referring to the auxiliary blood lipid lowering function evaluation method of appendix 6 in the "notification of 9 health care function evaluation methods (national food and drug supervision [2012]107 ]) regarding the antioxidant function evaluation method of the hair printing, a high cholesterol lipid metabolism disorder animal model can be formed by feeding animals with a feed containing cholesterol, lard and sodium cholate, and then a test sample can be administered to the animals, whereby the effect of the test sample on the hypercholesterolemia can be detected, and the effect of the test sample on the absorption of lipid, the formation of lipoprotein, the degradation of lipid or the excretion can be determined. The invention establishes a mixed type hyperlipidemia animal model.
Test animals: healthy adult male SD rats, 200+ -20 g,150 animals at the end of the adaptation period (5-7 days of animal feeding maintenance diet under barrier system).
And (3) molding: the animals were randomly divided into 2 groups according to body weight, the maintenance feed was given as a blank group to 10 animals, the model feed was given to 140 animals, the body weight was weighed 1 time per week, after 1-2 weeks of administration of the model feed, the blank group and the remaining animals were not fasted to collect blood (inner canthus or tail), serum was separated as soon as possible after blood collection, and the serum TC, TG, LDL-C, HDL-C level was measured to determine whether molding was successful.
Sample administration: 140 rats successfully molded were randomly divided into 14 groups according to TC levels, 13 of the groups were orally administered daily as test sample groups for 1g/kg/d of samples in examples 1-7 and comparative examples 1-6, the remaining 1 group was simultaneously administered with the blank control group as a model control group with the same volume of the corresponding solvent, the blank control group was continuously administered with a maintenance feed, the model control group and the test sample group were continuously administered with a model feed, and weights were periodically weighed, blood was collected without fasting at the end of the experiment, serum was separated as soon as possible after blood collection, and the serum TC, TG, LDL-C, HDL-C levels were measured, and the test results were counted in Table 4.
TABLE 4 Table 4
Figure BDA0002446202030000121
Figure BDA0002446202030000131
( And (3) injection: comparison with model control group: p < 0.05, compared to the blank #: p is less than 0.01 )
As can be seen from Table 4, the model control group showed a significant increase in TC, TG, LDL-C (P < 0.01) compared with the blank control group, indicating that the model group showed abnormal blood lipid in rats, and the modeling was successful. Compared with the model control group, the contents of TC, TG and LDL-C in the serum of the rats in the examples 1-7 are obviously reduced, the HDL-C content is increased, and the corresponding values of the rats eating the braised polygonatum food prepared by the technical scheme outside the protection scope of the invention are worse than those of the examples. In addition, the effect of reducing blood fat of the polygonatum odoratum or the raw polygonatum odoratum prepared by other modes is also inferior to that of the braised preparation method. Compared with the polygonatum food prepared by other technical schemes, the instant braised polygonatum food has good auxiliary blood fat reducing effect, wherein the instant braised polygonatum food prepared by the method of the embodiment 3 has better effect, and the embodiments 6 and 7 are subjected to subsequent moistening, so that the effect of the food can be further improved.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
