Pleurotus eryngii slice drying processing method and application thereof

Abstract

The invention belongs to the technical field of fungus processing, and discloses a pleurotus eryngii slice drying processing method and an application thereof. The pleurotus eryngii slice drying processing method comprises the following steps of: slicing pleurotus eryngii, immersing pleurotus eryngii slices in a steeping liquor, drying the immersed pleurotus eryngii slices at a high temperature, and then drying the pleurotus eryngii slices at a low temperature to obtain the dry pleurotus eryngii slices. Due to the adoption of the method, the original nutrients of the pleurotus eryngii can be well protected, the loss of the nutrients can be avoided in the drying process, a good color protection effect can be realized, the obtained dry pleurotus eryngii slices are good in color, the rehydrate rate is high, and the comprehensive quality is good. The method is economical and simple, the requirement on production equipment is low, the maintenance cost is low, and for the method, the industrialization and the mass production are easy to implement.

Description

technical field [0001] The invention belongs to the technical field of fungus treatment and processing, and in particular relates to a drying processing method and application of pleurotus eryngii slices. Background technique [0002] Pleurotus eryngii Quel, also known as Pleurotus eryngii, alias oyster mushroom, snow velvet or scallop mushroom, belongs to Fungiphylum, Basidiomycetes, Agaricaceae, Pleurotaceae, and Pleurotus genus. It is successfully developed and cultivated in recent years. A new species of rare edible fungus that integrates edible, medicinal and therapeutic uses. Pleurotus eryngii mushroom has thick meat, crisp texture, fresh and tender taste, fragrant taste, pleasant almond fragrance and abalone-like taste. It is a kind of flat mushroom with excellent taste. ". And Pleurotus eryngii is rich in nutrition, containing a lot of protein, sugar and multivitamins. [0003] In the 1950s, Europe was the first to carry out artificial domestication and cultivatio...

Problems solved by technology

[0004] However, the current domestic consumption of Pleurotus eryngii is mainly fresh, supplemented by a small amount of primary processed products and dried products. However, new products of Pleurotus eryngii have a short shelf life, and mildew spots, soft tissues, and surface defects appear after about 7 days of storage at low temperature. Quality deterioration such as melting and sticking

At present, the output of fresh Pleurotus eryngii is large, the production concentration is strong, and the consumption of fresh products is slow, which will easily cause a large number of fresh Pleurotus eryngii to decline in quality and cause economic losses. Breeding of edible fungus pests such as flies

[0005] There are few dried products of Pleurotus eryngii on the market, and there are a small number of dried products of Pleurotus eryngii that have problems in color and quality. Color protection, but the vulcanization treatment will damage the nutritional components of the dry product; some dried Pleurotus eryngii products have problems such as looseness, over-brittleness, and poor rehydration after processing.

In the prior art, there are researches on drying processes such as improving the rehydration rate and color protection of Pleurotus eryngii dry product, but most of them are related technologies such as vacuum drying and vacuum freeze drying. Processes such as vacuum or vacuum freezing can effectively improve the quality of dried Pleurotus eryngii, but they have high requirements for drying equipment, high maintenance costs, and are difficult to industrialize

Moreover, most of the current research on the drying process of Pleurotus eryngii only considers a single basic index such as color or rehydration rate to determine the quality of the dry product, and lacks a processing technology that comprehensively considers nutrition, texture, rehydration and color.

[0006] At the same time, the existing Pleurotus eryngii processing industry chain is monotonous, there are few types of processed products and enterprises, and the utilization of Pleurotus eryngii is not high
