Problems solved by technology

[0006] At present, the scale of industrial cultivation of Flammulina velutipes is expanding day by day, and the resulting waste of mushroom feet brings new processing difficulties; and the mushroom feet of Flammulina velutipes contain multiple effective active ingredients, which are directly burned, which will pollute the environment and cause waste of resources
In addition, there are many reports on the single extraction of a certain component from the feet of Flammulina velutipes, but there is a lack of comprehensive utilization technology for compound extraction or continuous extraction of multiple components from the feet of Flammulina velutipes

Abstract

The invention discloses a method for continuously extracting polysaccharides, protein and dietary fiber from the feet of Flammulina velutipes. The waste of the feet of Flammulina velutipes is used as raw materials, and the steps of extracting polysaccharides with water, extracting protein with alkali and extracting dietary fiber with alkali are carried out successively. Multiple active ingredients of polysaccharide, protein and dietary fiber can be obtained by continuous extraction from mushroom feet. The extraction process involved in the present invention is simple and low in cost, avoids the environmental pollution problem caused by direct combustion, realizes the recycling and utilization of resources, and has great application and development prospects; the polysaccharide, protein and dietary Fiber can be used in food, medicine, functional health care and other aspects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for continuously extracting polysaccharide, protein and dietary fiber from the feet of Flammulina velutipes. Background technique [0002] Flammulina velutipes is rich in protein and also contains VB 1 , VB 2 , Vc and other vitamins, and rich in calcium, phosphorus, iron and other minerals, the nutrition is very rich. Flammulina velutipes also contains 18 kinds of amino acids, and the total amount of amino acids per 100g of fresh mushrooms reaches 20.9mg, which contains 8 kinds of amino acids necessary for the human body, accounting for 42.29-51.17% of the total amino acid content. Among the essential amino acids, arginine and lysine The acid content is high, and the content of lysine and arginine per 100g of dry product reaches 1.024g and 1.231g, which is higher than that of common mushrooms. [0003] Flammulina velutipes polysaccharide is the mos...
