Abstract

The invention discloses a fresh keeping agent for needle mushrooms and a preparation method of the fresh keeping agent, and belongs to the technical field of fresh keeping of fruits and vegetables. The fresh keeping agent for the needle mushrooms, disclosed by the invention, comprises the following raw materials in parts by weight: 5-10 parts of chitosan, 5-10 parts of ascorbic acid, 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 fresh keeping agent for the needle mushrooms. The preparation method comprises the steps of mixing the raw materials, performing ultrasonic dispersion and subpackaging finished products. After the fresh keeping agent is diluted, precooled needle mushrooms are directly soaked in the diluted fresh keeping agent, and after the soaked needle mushrooms are naturally aired, the aired needle mushrooms can be encapsulated for preservation. The fresh keeping cost is low, the fresh keeping time is long, the fresh keeping shelf time of the needle mushrooms can be prolonged to 30 days, the quality of the needle mushrooms is controlled good, the freshness and the nutrient components of the needle mushrooms are sufficiently guaranteed, the fresh keeping agent does not have any toxic and side effects on human bodies, the fresh keeping agent is safe and environmental-friendly, and requirements of people for the diversification of the needle mushrooms are met.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping agent for Flammulina velutipes and a preparation method thereof. Background technique [0002] The scientific name of Flammulina velutipes is Enoki Mushroom, also known as Flammulina velutiper (Fr. ) Sing. Because of its slender stipe, like golden needle dish, so claim Flammulina velutipes; Belong to Agaricaceae Flammulina genus Flammulina genus, is a kind of algae lichen class. Flammulina velutipes is rich in a large amount of amino acids, protein, vitamin B1 and vitamin B2 etc., It has a high medicinal and dietary effect, can lower cholesterol, relieve fatigue, inhibit cancer cells, and improve immunity, and is deeply loved by people. [0003] After being harvested, Flammulina velutipes tends to lose its original color, aroma, and taste due to its tender tissue, high water content, and strong breathing. The traditional preservati...
