Embodiment 1
[0037] The method for the microbial fermented product cultivated under the music environment of embodiment 1 of the present invention
[0038] In a preferred embodiment of the present invention, vegetable juice (freshly squeezed juice) and berry juice (freshly squeezed juice) are mixed in a ratio of 3 to 2, and then diluted 5 times with distilled water as the empty culture solution; Juices containing: blueberry, cranberry, red grape, white grape, bayberry, mulberry, apple, carrot, sugar cane, passion fruit, pineapple, and lemon in equal parts; vegetable juice containing: broccoli, celery, and asparagus, their mixture in equal proportions. The air-culture liquid was treated by Pasteur sterilization, and then Streptococcus thermophilus (Streptococcus thermophilus), Saccharomyces cerevisiae (Saccharomycescerevisiae) and acetic acid bacteria (Acetobacter aceti) were introduced into the air-culture liquid for pre-fermentation. Ferment at 30°C ± 1°C for 192 hours at a constant temp...
Embodiment 2
[0039] Example 2 Detection of the superoxide dismutase (SOD-like) content of the microbial fermentation product of the present invention
[0040] Superoxide dismutase (SOD) is an enzyme that catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide. These enzymes play an important role in antioxidant defense in cells exposed to oxygen. Therefore, the present invention utilizes SOD activity kit (SOD activity kit, Enzo Life Science Company, model CAT#ADI-900-157) to analyze cellular oxidative stress.
[0041] The result is as figure 1 As shown, compared with the control group (only the enzymes that did not listen to music), no matter in which kind of music environment (classical music, pop music and rock music), the microbial fermentation products cultivated can effectively improve the superoxide dismutase ( SOD-like) content is more than 1 times, it can be inferred that its antioxidant capacity will be higher than that of microbial fermentation product...
Embodiment 3
[0042] Embodiment 3 Stomach cell antioxidant capacity of the microbial fermentation product of the present invention
[0043] The present invention uses a cell platform to test the antioxidant capacity, and uses quantitative real-time polymerase chain reaction (Quantitative real time PCR, qPCR) to detect the superoxidation of AGS human gastric epithelial cells (gastric epithelial cells) treated with the microbial fermentation product of the present invention. The gene expression level of substance dismutase 2 (SOD2) was used to analyze the gastric cell antioxidant capacity of the microbial fermentation product of the present invention.
[0044] The present invention uses human gastric epithelial cells purchased from American Type Culture Collection (ATCC), number CRL-1739. The cells were cultured in a medium supplemented with 10% fetal bovine serum (FBS) (GIBCO Company, No. 10438-026, USA) and 1% penicillin / streptomycin (GIBCO Company, No. 15140-122, USA) RPMI 1640 basal medi...
