Method for preparing black fungus puffed ultramicro powder

Abstract

The invention discloses a method for preparing a black fungus puffed ultramicro powder. The method includes selecting black fungus sporophores to serve as a raw material, puffing black funguses by an instantaneous alternating temperature and pressure difference of a puffing tank of a puffing device, maintaining a valve between the puffing tank of the puffing device and a vacuum tank to be in an opening state all the time, subjecting the black funguses in the puffing tank to a vacuum drying, and subjecting the puffed black funguses to a coarse grinding and a superfine grinding to obtain the black fungus puffed ultramicro powder. According to the method, a high pressure gas serves as a carrier, by means of a puffing wall breaking process, a black fungus organization structure is subjected to a cytoclasis to release whole nutritional ingredients and medicinal effect ingredients which are easy to digest and use by human bodies, and problems that the black funguses are hard and not suitable for being chewed, digested and used are solved. Besides, when the black fungus puffed ultramicro powder can be mixed with foods of flours, cakes and the like, the black fungus puffed ultramicro powder has flavor and nutrition of the black funguses, and smoothing taste is increased. The method is low in production cost and suitable for industrialization production, and products are used for foods, health care foods, medicines and raw material extraction.

Description

technical field [0001] The invention relates to a method for preparing black fungus puffed superfine powder, which belongs to the technical field of agricultural product processing. Background technique [0002] Black fungus is one of the earliest artificially cultivated commercial fungi among edible fungus varieties in my country. Mainly distributed in Heilongjiang, Jilin, Fujian, Hubei, Guangdong, Guangxi, Shandong, Jiangsu, Sichuan, Guizhou, Yunnan and other places. According to statistics from the China Edible Fungi Association, the total output of black fungus in China in 2011 has exceeded 2.7 million tons, and the output has increased very rapidly. At present, my country's black fungus production and consumption rank first in the world. [0003] Black fungus [Auricularia auricular (L.ex Hook.) Underw] also known as black cabbage, light fungus, cloud ear, mycological classification belongs to Basidiomycetes, Auricularia, Agaricaceae. It is a precious colloidal fungus...

Problems solved by technology

[0007] 1. Dried and compressed black fungus is picked and dried in the sun or directly sold on the market after drying or compressed into blocks. This method is simply dehydration, prolongs the storage period, reduces volume, facilitates transportation, and does not break the cell wall wall, the absorption rate for direct consumption is still low

[0008] 2. Extract black fungus polysaccharides. Use dried fungus, crush them, pass through a 40-mesh sieve, soak in several times of water, keep warm, stir, then filter, precipitate, and dry to obtain black fungus polysaccharides. Although this method increases the dissolution of black fungus polysaccharides , but the process is longer and the cost is higher

[0009] The convenient variation of the ultrafine pulverization product in terms of physical properties and microstructure, as well as the convenience of extraction efficiency, solubility, adsorption, drug efficacy and bioavailability will all be improved. When the black fungus is refined to the micron and nanometer level, the functional components It will be easier to absorb quickly. At present, there have been a few reports on the research of black fungus ultrafine grinding. black fungus superfine powder, and compared the changes of black fungus amino acid and vitamin content after superfine powder pulverization, showing that the total amount of black fungus amino acids increased significantly after superfine pulverization, and compared the particle size, microstructure, rehydration and other properties of the pulverized sample, the results showed that the mechanical Combined with the black fungus superfine powder prepared by the vacuum freeze-drying method, the properties of the black fungus superfine powder prepared by the mechanical method are obviously better than those of the black fungus superfine powder prepared by the mechanical method. Great damage, the cell wall is not completely broken, and the functional ingredients cannot be fully released
