Abstract

The invention provides a preparation method of a food additive. Algae plants are used as raw materials, and the raw materials are subjected to acid-base abstraction, enzymolysis process and microwave process, so that the extraction efficiency of active substances of the algae plants can be obviously improved. In addition, the active components are modified through fermentation of bacterium colonies to have functions of breaking down macromolecule groups, removing harmful substances and the like. By the adoption of pasteurization, the prepared food additive can meet the edible requirement. The food additive can be applied in improving the health of organisms.

Description

technical field [0001] The invention relates to a preparation method and application of a food additive, in particular to a biological extraction method of functional active substances of seaweed plants, and uses seaweed plants as raw materials to prepare food additives. Background technique [0002] With the development of China's industrialization, environmental pollution has become a problem of great concern to the society. A large amount of water pollution, air pollution, soil pollution, and through the biological chain pollute the animal and plant products and water sources that human beings depend on for survival. Among them, heavy metal pollution and Covert ways to threaten food safety. Heavy metal pollution generally refers to the pollution of heavy metals such as lead, mercury, cadmium, and arsenic, which often harm humans in the form of chronic poisoning. Lead poisoning is a kind of cumulative poisoning, which mainly enters the human body through air, drinking wat...
