Description
Technical Field
The invention discloses a fruity selenium-rich cordyceps militaris yoghourt product and a preparation method thereof, wherein a selenium-rich cordyceps militaris mycelium with obviously enhanced selenium enrichment capability due to cell wall permeability change and defatted fresh milk are used as main raw materials, and a plurality of auxiliary materials such as hawthorn powder, pollen pini solution, sweetening agent, vitamins and the like are added, and four mixed preparations of streptococcus thermophilus, lactobacillus bulgaricus, lactococcus lactis diacetyl subsp, and lactobacillus acidophilus are inoculated for fermentation to obtain solid yoghourt, and the fruity selenium-rich cordyceps militaris yoghourt product belongs to the technical field of fermented yoghourt.
Background
The yoghourt is prepared by fermenting milk, and has more excellent nutritive value and absorption efficiency than raw milk. Many studies have shown that yogurt has outstanding effects on various health care and nutrition functions such as resistance to cancers caused by diet and stress, and increase of body fluid production. With the rapid development of fermentation technology, in order to increase the flavor and taste of the yogurt and fully utilize the nutrient components in the fermentation medium, the fermentation process is more sufficient, and the mixed fermentation is generally adopted at present, so that the requirements of different consumers can be better met. Although the yoghourt has high nutritive value, about 7 percent of white granulated sugar is usually added, and the fat content is also very high, so the yoghourt can not be eaten by diabetics.
Selenium is a trace element necessary for human bodies, is called as a 'life miraculous element' in the trace elements, and has two states of inorganic selenium and organic selenium in nature, and the organic selenium generally exists in the form of selenomethionine, is metabolized along a methionine metabolic pathway, participates in protein synthesis, and is easy to store and absorb in tissues; can be rapidly utilized by human body after being absorbed by human body, and effectively improve the blood selenium condition in human body. The average content of selenium in adult human body is 0.25 mg/kg. The selenium intake of human body should not be less than 50 μ g/day. The recent research results of American scientists suggest that healthy people can prevent the generation of tumors to a certain extent by supplementing 200 mug/day of selenium or adding a little more selenium in a proper amount. However, the maximum safe intake of selenium is 400 μ g/day, and excessive selenium may cause poisoning. In addition, the medicine also has the functions of regulating immunity, resisting HIV and other viruses, protecting brain and enhancing male reproductive function, and is closely related to thyroid function, autoimmune thyroid diseases, septicemia and other critical diseases, cardiovascular diseases and diabetes. However, the selenium content in natural food is generally low, and the food only needs to take selenium to maintain lifeExercise has been far from satisfying the needs of health. However, excessive intake of selenium can produce acute and chronic toxic effects on the body, and simultaneously produce various toxic and side effects such as genetic toxic effect of selenium (sodium selenite), and microorganisms are utilized to treat inorganic substance sodium selenite (Na)2SeO3) The organic selenium product can be directly obtained by biotransformation, and the subsequent treatment pressure is reduced. Can improve the physiological activity and absorption rate of selenium, and reduce the toxicity of selenium.

test example 1
Research on anti-fatigue activity of selenium-enriched cordyceps sinensis fermented yoghourt
Healthy male mice were taken, acclimated for 5 days before the experiment, and randomly divided into 6 groups: in the yogurt examples 1-4 groups, the negative control group (the yogurt group without selenium-enriched cordyceps) and the blank control group (0.1 ml/10g of normal saline) were stirred uniformly with 0.2ml of water, and then the mixture was continuously perfused into the stomach for 25 days, and free diet and drinking water were provided during the modeling period. After modeling, randomly selecting 10 mice in each group, after feeding yoghourt for 30min at the last time, loading lead blocks with the weight of 5% on the heel parts of the mice, placing the mice in a plastic bucket with the water depth of 30 cm, the diameter of 15 cm and the water temperature of 27-30 ℃, recording the swimming time of the mice, and taking the condition that the heads of the mice are completely immersed in the water and can not float out of the water again for 8s as a swimming finish mark. Removing blood from eyeball, standing at 37 deg.C for 30min to separate out serum. Centrifuging (1500 r/min) for 5min, collecting supernatant, and measuring SOD and MDA values and lactic acid content of blood serum; killing a mouse by dislocation of cervical vertebra, dissecting and taking liver, cleaning with normal saline, accurately weighing a certain amount of liver tissue after surface moisture is absorbed by filter paper, adding normal saline, homogenating in ice bath, centrifuging for 15 min at 3000 r/min by a low-temperature centrifuge, and taking supernatant to measure liver glycogen content. The results are shown in tables 5 to 6:
table 5 effect of yoghurt of the invention on weight bearing swimming time of mice (N = 10)
P <0.01, P <0.001 compared to control.
Table 6 effect of yoghurt of the invention on the viability of biochemical markers in mice (N = 10)
P <0.05 compared to control group.
As can be seen from Table 5, the weight-bearing swimming time of the mice can be remarkably increased after the yogurt is fed, and the anti-fatigue activity of the yogurt is superior to that of the negative control group.
Table 6 shows that, compared with the blank control group, the mouse eating the yogurt has the advantages of increased serum SOD activity, reduced serum MDA content, reduced blood lactic acid content, and significantly increased liver glycogen content, and thus, the anti-fatigue activity of the mouse can be improved by using the selenium-rich cordyceps militaris yogurt for a long time.

90 normal mice with half male and female are taken, and after being fed normally for 3d, the mice are randomly divided into 9 groups, namely a normal group, a hyperlipemia model group, a simvastatin group (6 mg/kg), a negative control group (a selenium-free cordyceps sinensis yoghourt group) and yoghourt examples 1-4. Except for the normal group of mice, other 6 groups of mice are respectively modeled by injecting 4% Triton solution into the abdominal cavity with the volume of 10 ml/kg, and after injection, the control group and the model group are given with the same volume of normal saline, and other groups are continuously injected with gastric yoghurt for 25 days. 3 h after the last time of feeding yoghourt, the mouse picks eyes to take blood, serum is separated, and TC, TG and HDL-C, LDL-C are respectively measured according to the instruction of the kit.
