Problems solved by technology

[0005] It can be found that the above examples of edible fungus processing and production, or focus on the flavor and shape of edible fungus products for deep processing, or extract and utilize a single nutrient in edible fungi, lack the retention and regulation of nutrients in the process of edible fungi processing
However, the existing processing technology of pilose antler mushroom is simpler, ignoring the utilization of its characteristic nutrients

Abstract

The invention discloses a preparation method of lyophyllum decastes nutritional ingredient powder, and belongs to the field of development and utilization of edible mushroom resources. The preparationmethod comprises the following steps of by taking lyophyllum decastes as a raw material, performing cleaning, performing cutting, performing combined treatment of vacuum microwave and vacuum freeze drying to obtain dried lyophyllum decastes slices which adopt a loose porous structure and of which the moisture content is 3-5%, and performing vibration type low-temperature superfine grinding to obtain the lyophyllum decastes nutritional ingredient powder with the particle size of 1600-5000 meshes. According to the method, the microstructure of the lyophyllum decastes slices is remarkably improved in the drying process, so that smaller-particle-size powder is obtained through superfine grinding, the dissolution rate of nutrient substances is increased, the total protein retention rate of theprepared lyophyllum decastes nutritional ingredient powder reaches 73-87%, the total sugar retention rate reaches 90-99%, the total phenol retention rate reaches 71-89%, and the nutritional ingredient retention rate is increased to the maximum extent. The nutritional ingredient powder as low as the nanoscale is high in plasticity, so that development of various product forms is facilitated.

Description

technical field [0001] The invention relates to the field of development and utilization of edible fungus resources, in particular to a preparation method of pilose antler mushroom nutritional ingredient powder. [0002] technical background [0003] Antler mushroom scientifically known as Lyophyllum decastes, contains high protein, low fat, a variety of trace elements, rich in ergosterol and essential amino acids needed by the human body. It has physiological functions such as enhancing the immune regulation of the body and relieving chronic diseases. It is a precious medicinal and edible fungus. Studies have proved that the polysaccharides in the fruiting bodies of pilose antler mushrooms have anti-tumor, anti-oxidation, and hypoglycemic and lipid-lowering effects. At present, the consumption of antler mushrooms is mainly fresh food, and researches pay more attention to its cultivation technology and biological characteristics, and the development rate of related processed...
