Problems solved by technology

[0002] Boletus is a kind of wild edible fungus with rich nutrition, unique flavor, delicious taste and crisp texture. The forms of export or domestic products are mainly salted boletus and dried boletus. With the development of technology, quick-frozen boletus gradually replaces salted boletus and becomes the mainstream product. However, due to the production of quick-frozen boletus The process and quick-freezing parameters are different, and the quality of quick-frozen boletus varies. At present, the main problem in the production process and quick-freezing parameters is that when quick-freezing, excessive ice crystals are formed in the intercellular space of the boletus tissue, and the water in the cells leaks out, resulting in When thawing, the juice loss is more, the color changes greatly, and the original characteristics of the boletus are lost, which affects the quality of the product.
