Problems solved by technology

[0004] Existing mushroom cling film mainly uses PE and PVC as raw materials. The cling film made of these materials has good gas barrier performance, which is not conducive to the penetration of oxygen, carbon dioxide and water vapor, and easily causes anaerobic respiration of mushrooms. Water droplets provide conditions for the growth and reproduction of microorganisms, and to a certain extent, accelerate the decay of mushrooms

Abstract

The invention discloses a preparation method of a mushroom preservative film, and belongs to the field of food fresh keeping. The method comprises the following steps: with polylactic acid, citric acid ester compounds and natural antibacterial plant essential oil as raw materials, preparing a composite film through a solvent membrane method; carrying out thermal plastic package on the composite film according to the packaging amount, so as to prepare a bag-shaped packaging bag; putting the clean fresh mushroom into the packaging bag, wherein the mushroom loading amount is 50-80% of the volume of the packaging bag; filling in fresh air and then sealing; and storing in a refrigerator with the temperature being 6+ / -1 DEG C. The preservation method is simple in process, and easy to operate; the used materials can achieve biodegradation, and reduce environmental pollution caused by package; due to addition of the natural antibacterial plant essential oil, according to the preservative film used in the preservation method, the mechanical property of the preservation film is improved, the breathability of the preservation film is increased and the preservative film is relatively suitable for modified atmosphere packaging of the mushroom; meanwhile, the preservative film also has certain bacteriostatic action, and is capable of restraining growth and reproduction of microorganisms; and the preservation method is capable of effectively prolonging the storage life of the mushroom.

Description

technical field [0001] The invention relates to a preparation method of a mushroom fresh-keeping film, which belongs to the field of food preservation. Background technique [0002] Mushrooms are delicious, low in calorific value, rich in protein, vitamins and minerals, almost free of cholesterol and fat, and have strong antioxidant activity. widespread attention. In recent years, the production scale of edible fungi has been continuously expanded, the cultivation technology has been greatly improved, and the output has continued to increase. With the improvement of people's consumption level and the pursuit of natural flavor, the proportion of fresh mushrooms is increasing year by year. However, fresh mushrooms still have vigorous physiological activities during storage and transportation after picking. Due to the soft tissue, high water content, and high respiratory intensity, spoilage bacteria and other microorganisms are easy to breed during storage, and the mushroom b...
