Preparation method of papaya enzyme

Abstract

The invention discloses a preparation method of a papaya enzyme. The preparation method comprises the following steps of (1) cleaning papayas, cutting the cleaned papayas into papaya dices, adding the papaya dices into a chlorine dioxide solution, and soaking the papaya dices in the chlorine dioxide solution; (2) performing color protection on the soaked papaya dices, and performing freezing and unfreezing treatment; (3) performing mashing on hydromel and the processed papaya dices, and performing centrifugation so as to obtain papaya residues and papaya honey juice; (4) taking the papaya honey juice, the papaya residues, magnesium sulphate, zinc sulfate and brown sugar, adding the taken papaya honey juice, the taken papaya residues, the taken magnesium sulphate, the taken zinc sulfate and the taken brown sugar into a fermentation tank, performing uniform stirring, at the same time, adding potassium dihydrogen phosphate and dipotassium hydrogen phosphate to the fermentation tank for regulating pH, performing sterilization treatment on fermented feed liquid in the fermentation tank through ultraviolet rays, then adding microzyme for fermentation, performing filtration, and removing filter residues so as to obtain crude papaya enzyme liquid; and (5) performing pretreatment on the crude papaya enzyme liquid in a high voltage pulse treatment room through a high voltage pulse electric field, and then performing sterile filling so as to obtain the papaya enzyme. The preparation method disclosed by the invention is simple in technology, convenient to operate and easy to implement and popularize; besides, compared with some artificial papaya enzymes, the papaya enzyme prepared by the preparation method disclosed by the invention has the advantages that the fermentation time is obviously shortened, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of papaya enzyme. Background technique [0002] Enzyme, academically, is another concept of multiple enzyme complex systems. It is an essential substance to maintain the normal functions of all living animals, plants and microorganisms. The lack of enzymes in the human body can easily cause various diseases. Therefore, taking enzyme supplement food It is very beneficial to the human body; as a health food, enzymes refer to fresh vegetables, fruits and other plants as raw materials, which are produced by fermentation of a variety of probiotics, and are rich in enzymes, vitamins, minerals and secondary metabolites microbial agents. Studies have shown that enzyme food has the functions of anti-inflammatory, antibacterial, anti-oxidation, purifying blood, promoting cell regeneration, enhancing immunity, etc., and some also show certain anti-tumor effects.

Problems solved by technology

[0005] The production process of natural papaya enzyme is simple, but the production cycle is long, and there are still the following disadvantages: first, it is easy to cause the growth of spoilage bacteria or mildew, because most of them are fermented by various microorganisms in the air, Although the finished product is an enzyme, it cannot be completely guaranteed to be free of pathogenic bacteria, and it is easy to cause food poisoning due to accidental ingestion; second, the enzyme activity cannot be effectively retained; third, the fermentation time cannot be effectively controlled, resulting in uncontrollable quality
