Problems solved by technology

However, as can be seen from the examples, the SOD activity is low when only guava extract (sample 1) and only rice bran and soybean fermented product (sample 2) are used, and the active oxygen scavenging effect is insufficient.
And, because the acquisition of guava leaves is limited by seasons, there are difficulties in practical use of this method as well.
[0006] As mentioned above, in the prior art, among substances having an active oxygen scavenging effect, no substance having both high SOD activity and practical use has been found.

Embodiment 1～ Embodiment 3

[0046] Plant lactic acid bacteria shown in Table 1 below were used as microorganisms for producing an antioxidant (active oxygen scavenger) from okara.

[0047] Table 1

[0048]

[0049] * The above-mentioned microorganisms were all obtained from Jiangnan University and preserved in CICIM, the Industrial Microbiology Resource and Information Center of Chinese Universities.

[0050] The above strain obtained by culturing in YPD (Yeast Extract Peptone Dextrose Medium) medium at 30°C was inoculated into an Erlenmeyer flask (capacity 300ml) containing 100ml of antioxidant production medium, and cultured at 30°C for 72 hours. The medium contained 10 w / v% okara and 1 w / v% glucose. Wherein, the preparation of soybean dregs is obtained by soaking soybeans in water for 12 hours to make soybeans fully absorb water, then grinding and crushing the soybeans that have absorbed water, filtering and removing liquid components, and draining remaining residues.

[0051] Then, the obtained...

Abstract

The invention relates to a preparation method of an antioxidant. The preparation method of the antioxidant provided in the invention comprises the following steps: culturing plant lactobacillus in a culture medium containing soybean residues, and obtaining the antioxidant from the resultant supernatant. The invention also provides the antioxidant having a high SOD activity obtained through the preparation method. The antioxidant is obtained through utilizing a specific microbe and adopting the byproduct soybean residues of the food processing industry and the like as a main raw material of the medium according to the preparation method provided in the invention, and the preparation method has the advantages of low cost and high efficiency.

Description

technical field [0001] The present invention relates to a production method of an antioxidant and an antioxidant with high SOD activity obtained by the production method. Background technique [0002] SOD is the English abbreviation of superoxide dismutase (superoxide dismutase), which is an antioxidant enzyme synthesized in the human body. SOD decomposes harmful superoxide radicals produced by various reasons in the human body into hydrogen peroxide (a type of active oxygen), and then further decomposes hydrogen peroxide by the action of catalase and peroxidase It is completely harmless water and oxygen, so it has the effect of reducing the concentration of active oxygen in the body, and has the effect of preventing and improving skin roughness, spots, and wrinkles caused by active oxygen. Therefore, SOD products have been widely used in the fields of food, cosmetics, and pharmaceuticals as a method for preventing aging. However, most of the existing SOD products are deri...
