Problems solved by technology

At the same time, these fresh-keeping techniques may cover up the color and flavor of the morel itself, that is, the flavor is poorly acceptable, such as potassium sorbate as a bacteriostatic agent or preservative, which has a bad smell, and the use of edible oil may affect the color.
At present, domestic academic circles have few studies on the preservation of morels among edible fungi. Some master thesis mentioned that the polysaccharide extract of Dictyophora spinosa mycelium can be directly used as a fresh-keeping agent for morels. This method may cause Bring in other odors

Embodiment 1

[0035] Embodiment 1: the preparation of hickory chick antistaling agent and its fresh-keeping effect test 1

[0036] A, the preparation of hickory chick preservative

[0037] The morel preservative is composed of the following ingredients according to a certain mass percentage: first dissolve 0.15% morel polysaccharide in water, stir to dissolve, then add 0.13% morel chitosan, 0.12% ascorbic acid, 0.1% Acetic acid, 0.15% sodium chloride, and water as the rest, stirred to dissolve, and left at room temperature for later use.

[0038] Wherein, hickory chick polysaccharide is prepared according to the following steps:

[0039] (1) passing through 100 mesh after the freeze-dried hickory chick fruiting body tissue is purified, obtain hickory chick powder;

[0040] (2) Add 30 times the volume of water to the hickory chick powder described in step (1), place it in an ultrasonic extractor for ultrasonic extraction, the temperature is a constant temperature of 60°C, the ultrasonic po...

Embodiment 2

[0053] Embodiment 2: the preparation of hickory chick antistaling agent and its fresh-keeping effect test 2

[0054] A, the preparation of hickory chick preservative

[0055] The morel preservative is composed of the following ingredients according to a certain mass percentage: first dissolve 0.2% morel polysaccharide in water, stir to dissolve, then add 0.15% morel chitosan, 0.14% ascorbic acid, and 0.12% lemon Acid, 0.17% sodium chloride, and the rest in water, stir to dissolve, and place at room temperature for later use. Wherein, hickory chick polysaccharide and hickory chick chitosan originate from the product that the preparation method of hickory chick polysaccharide and hickory chick chitosan in embodiment 1 obtains.

[0056] b. Fresh-keeping effect test 2 of Morchella preservative

[0057] Select individual complete fresh Morchella fruiting bodies, wash them, drain them, soak them in preservatives for 10 minutes, take them out and drain them, put them on a plate and...

Embodiment 3

[0059] Embodiment 3: the using method of hickory chick antistaling agent and its fresh-keeping effect test 3

[0060] a. How to use morel preservative

[0061] (1) Dehumidification of Morchella: Wash the freshly harvested Morchella fruiting body intact, bright in color and free from diseases and insect pests, drain it naturally and place it in a refrigerator. Keep the indoor temperature at 25°C to remove water vapor in the air. And continuously feed dry air, the pressure of the dry air is 1KPa, and process for 30min;

[0062] (2) Morchella decompression and pre-cooling treatment: the refrigerating chamber is vacuumized to keep the pressure in the refrigerating chamber at 0.5KPa, and the temperature in the refrigerating chamber is reduced to 1°C within 20min; After 5h, slowly adjust the pressure of the refrigerator to atmospheric pressure, and take out the hickory chick;

[0063] (3) Soak the morel mushrooms pretreated in step (2) in the antistaling agent for 7 minutes, take ...

Abstract

The invention discloses a fresh keeping agent for morchella and an application thereof and belongs to the field of fresh keeping of edible mushrooms. The fresh keeping agent includes morchella polysaccharide extract, morchella chitosan, ascorbic acid, a pH regulator, sodium chloride, and the balanced being water. The application includes the steps of: cleaning fresh morchella fruiting bodies and performing dehumidification; performing pressure-reduced pre-freezing treatment; soaking the morchella in the fresh keeping agent for 7-10 min, draining the morchella, placing the morchella on a plate and sealing the plate, and sealedly storing the morchella at 3-5 DEG C away from light. The fresh keeping agent is safe and high-effective and has no toxic and side effects on human body, can effectively prolong the fresh keeping time of fresh morchella and maintain the flavor and color of the morchella, is easy to carry out and has good fresh keeping effects.

Description

technical field [0001] The invention relates to the fresh-keeping field of edible fungi, in particular to a fresh-keeping agent using morel polysaccharide and morel chitosan as natural fresh-keeping components and an application thereof. Background technique [0002] Morchella, also known as delicious morel, is commonly known as goat sparrow, corn fungus, etc. Belongs to Ascomycotina, Panmycota, Panmycetes, Morchellaceae, Morchella genus.
