Abstract

The invention discloses an Agrocybe aegerita preservative and a preparation method thereof and belongs to the technical field of fruit and vegetable preservation. The Agrocybe aegerita preservative comprises raw materials in parts by weight as follows: 5-10 parts of chitosan, 5-10 parts of sodium alginate, 1-5 parts of tea polyphenol, 3-8 parts of inulin, 5-10 parts of pullulan and 100-120 parts of sterile water. The invention further provides the preparation method of the Agrocybe aegerita preservative. According to the preparation method, the raw materials are mixed, subjected to ultrasonic dispersion and subpackaged. The precooled Agrocybe aegerita is directly soaked in the diluted preservative and can be packaged and stored after being dried in the air naturally; the preservation cost is low, the preservation time is long, the preservation and storage period of the Agrocybe aegerita can be prolonged to 30 days, the quality is controlled well, the freshness and nutrition facts of the Agrocybe aegerita are guaranteed sufficiently, toxic and side effects on a human body are avoided, safety and environmental protection are realized, and diverse requirements for the Agrocybe aegerita are met.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, in particular to a tea tree mushroom fresh-keeping agent and a preparation method thereof. Background technique [0002] Tea Tree Mushroom is rich in nutrition, with a protein content as high as 19.55%. There are 18 kinds of amino acids in the protein, and the total amino acid content is 16.86%. It is a pure natural pollution-free health food that combines high protein, low fat, low sugar, and health care bacteria. The optimized and improved tea tree mushroom has a tender cover and a crisp stalk, a pure and fragrant taste, and an excellent taste. It can be cooked into various delicacies. Its nutritional value exceeds other edible fungi such as shiitake mushrooms, and it belongs to high-grade edible fungi. [0003] After the tea tree mushroom is harvested, due to its tender tissue, high water content, and strong breathing, it is easy to lose its original color, arom...
