Abstract

The invention discloses an edible biological preservative for morchella and application thereof and relates to the technical field of preservation of edible fungi. The formula of the preservative specifically comprises 100 ml of 0.75% chitosan, 30 ml of 0.03% natamycin, 20 ml of 1.5% sodium chloride and 850 ml of purified water, wherein the pH value is regulated to 6.0. In addition, the inventionprovides a morchella preservation method. The preservation method specially comprises the steps of conducting precooling processing on morchella under reduced pressure, soaking the processed morchellawith the preservative, then spraying a radix angelicae volatile oil solution, executing air-drying, executing sealing, storing the morchella in a preservation bag at the constant temperature of 4 DEGC and executing selling. The preservative and the preservation method can effectively prolong the preservation time of morchella.

Description

technical field [0001] The invention relates to the technical field of preservation of edible fungi, in particular to a method for extending the shelf life of hickory chick by using a food preservation agent without toxic and side effects. Background technique [0002] Morchella has become the most famous and precious edible and medicinal fungus in Ascomycetes because of its rich nutrition, anti-tumor, lowering blood fat, improving immunity and unique flavor. The fruiting body tissue of fresh Morchella is relatively brittle and tender, with high water content, and it is easily infected by microorganisms after slight mechanical damage, resulting in spoilage and deterioration of the fruiting body. After being harvested at room temperature for 1d to 2d, the water in the fruiting bodies will be lost in large quantities, browning and even fruiting bodies will rot, resulting in a decrease or even loss of its commodity value. Once morel mushroom products are backlogged because the...
