Embodiment 1
[0033] Example 1 In the present invention, the efficacy is investigated according to the following detection methods.
[0034] 1. The detection method for in vitro detection of hypoglycemic activity is as follows:
[0035] Reagent configuration method
[0036] α-amylase solution: take 10 mg of α-amylase (porcine pancreas), dilute to 10 mL with ultrapure water, and store at 4°C for later use.
[0037] Soluble starch solution: take 1g of soluble starch, add 80mL of ultrapure water to boil and dissolve, after cooling, dilute to 100mL with ultrapure water, and store at 4°C for later use.
[0038] DNS solution: Take 2.1g of NaOH, add 50mL of ultrapure water, heat in a water bath at 45°C, add 18.2g of potassium sodium tartrate, 0.63g of DNS, 0.5g of phenol, and 0.5g of sodium sulfite in sequence, and keep stirring until the solution is Clear and transparent, cool to room temperature, dilute to 100mL with ultrapure water, store in a brown bottle, keep away from light, store at room...
Embodiment 2
[0102] Rosa roxburghii powder and water are mixed according to the solid-liquid ratio of 1:10 to obtain roxburghii juice, and then the roxburghii juice and wolfberry juice are mixed and sterilized according to the compound ratio of 1:1; Saccharomyces cerevisiae BCGQ2107 seed liquid is cultivated to logarithmic Growth period OD 600 =0.6; the inoculation amount of S. cerevisiae BCGQ2107 seed solution was 3%; the fermentation temperature was 28°C, the fermentation time was 48h, and the rotation speed was 200r / m; The addition amounts of dextrin, xanthan gum and CMC are 1%, 0.005%, 0.1%, 1%, 0.05% and 0.05% respectively; homogeneous degassing, sterilization and filling.
[0103] The fermented juice beverage prepared according to the above formula has a refreshing mouthfeel and a slightly sour taste. The in vitro hypoglycemic activity can reach about 45%, the uric acid lowering activity can reach about 25%, and the scavenging rate for DPPH free radicals can reach about 91%. - The s...
Embodiment 3
[0108] Rosa roxburghii powder and water are mixed according to the solid-liquid ratio of 1:10 to obtain roxburghii juice, and then roxburghii juice and wolfberry juice are mixed and sterilized according to the compounding ratio of 3:1; Saccharomyces cerevisiae BCGQ2107 seed liquid is cultivated to logarithmic Growth period OD 600 =0.7; the inoculation amount of S. cerevisiae BCGQ2107 seed solution was 4%; the fermentation temperature was 28°C, the fermentation time was 54h, and the rotation speed was 200r / m; The addition amounts of dextrin, xanthan gum and CMC are 1.5%, 0.01%, 0.05%, 1.5%, 0.05% and 0.05% respectively; homogeneous degassing, sterilization and filling.
[0109] The fermented juice drink prepared according to the above formula has a smooth mouthfeel, moderate sweet and sour, in vitro hypoglycemic activity can reach about 60%, uric acid lowering activity can reach about 37%, and the scavenging rate for DPPH free radicals can reach about 93%. - The scavenging rat...
