Technical Field

the invention belongs to the technical field of food processing, and particularly relates to a royal jelly antioxidant peptide fruit enzyme and a preparation method thereof.

background

The ferment is low-salt liquid containing bioactive substances extracted from deep fermentation of plants. The bioactive components at least comprise enzyme and fermentation-participating bacteria. The enzyme contains bioactive components, which can affect active enzyme in body of user, and regulate body's life activity from cell layer. The probiotic enzymes prepared by anaerobic fermentation are mainly probiotics and food materials, and the side effects of the probiotics and the food materials are almost zero. Therefore, the probiotic ferment is a safe health product with life activity. By reasonably selecting food materials and the ferment prepared by the fermentation process, one or more ferment with magical effects can be respectively formed, such as effects of regulating immune response, resisting cancer, lowering blood pressure, regulating intestine, eliminating constipation, resisting gout and type II diabetes, reducing weight, and resisting allergy. The ferment has great application prospect as a unique health care product with vitality.

Enzymes are closely related to our daily life. The high-intensity overload fast-paced working and living modes of the modern society, various bad living habits and the increase of ages can all cause the reduction of enzymes in human bodies. The enzymes synthesized by human body and secreted by bacteria are only a small part, and can not meet the requirements of human body. Therefore, more enzymes must be taken from the diet, but the food generally needs to be subjected to high temperature or fine processing, and the enzymes in the food are damaged and remain a few; therefore, the amount of enzymes taken from the diet is very limited, and the enzymes reduced in the human body cannot be effectively compensated.

The royal jelly is rich in high-activity nutrient substances and has a very prominent health-care effect. However, the royal jelly has special taste and can not be adapted by general people; in addition, royal jelly is hot in nature, so that the royal jelly is suitable for limited people.
