Problems solved by technology

However, after harvesting, due to the tender tissue, high water content, and strong breathing, it is easy to lose its original color, aroma, and taste, and it will open umbrellas, brown, and taste, which seriously affects its product quality and shelf life.
The traditional preservation of Flammulina velutipes uses sodium metabisulfite for color protection and potassium sorbate for antisepsis. Although it has a good effect, it has toxic side effects and carcinogenic effects on human health.
In addition as V C Used for color protection and inhibition of browning, the effect is poor and unstable

Abstract

The invention discloses a compound biological preservative for golden mushrooms and an application method thereof, belonging to the field of edible mushroom preservative. The compound biological preservation for golden mushrooms is a hydrosolvent, comprising the components of: 0.001%-0.01% by weight of L-cysteine, 0.01%-0.05% by weight of nisin, 0.01%-0.15% by weight of calcium chloride, and 1%-9% by weight of bamboo fungus extract. When the compound biological preservative for golden mushrooms is applied, precooled golden mushrooms are immersed or sprayed with the compound biological preservative, then the golden mushrooms are blown dry by an air cooler or aired, and finally the golden mushrooms are sealed in a freshness protection package and stored at a temperature between 0 degree and 5 degrees. The compound biological preservative has long preservation time, excellent quality control and no toxic and side effects to a human body, and the application method has simple operation, low cost, safety and environment protection.

Description

technical field [0001] The invention relates to the field of edible fungus antistaling agents, in particular to a compound biological antistaling agent of Flammulina velutipes and a fresh-keeping method thereof. Background technique [0002] Flammulina velutipes is widely distributed in nature, and is famous in the world for its rich nutrition and delicious taste. However, after harvesting, due to the soft tissue, high water content, and strong breathing, it is easy to lose its original color, aroma, and taste, and open umbrellas, browning, and odors, etc., seriously affect its product quality and shelf life. The traditional preservation of Flammulina velutipes uses sodium metabisulfite to protect color and potassium sorbate to preserve it. Although it has a good effect, it has toxic side effects and carcinogenic effects on human health. In addition as V C It is used for color protection and inhibition of browning, but the effect is poor and unstable. Therefore, it is of ...
