Method for producing flaxseed gum and flaxseed kernels

Abstract

The invention relates to a method for producing flaxseed gum and flaxseed kernels, which is characterized by comprising the following steps of: 1, cleaning and removing impurities; 2, polishing and degumming and separating the gum from the flaxseed kernels: putting clean flaxseeds into a sand roller polishing machine for polishing the flaxseed gum on the surface layer of the flaxseeds into gum powder, sucking the gum powder through a screen net of the sand roller polishing machine by an air suction duct, collecting to obtain the flaxseed gum powder, collecting flaxseed grains of the sand roller polishing machine; 3, grinding, twisting and shelling the flaxseed grains; 4, separating shells from kernels to obtain the flaxseed kernels: conveying a shelled flaxseed shell / kernel mixture to a shell / kernel separating machine to respectively obtain flaxseed shells, flaxseed kernels and unshelled flaxseed grains; and 5, degreasing the gum powder to obtain the flaxseed gum: screening the flaxseed gum powder, degreasing the screened gum powder by adopting an organic solvent, and drying to obtain the flaxseed gum. According to the method, the flaxseed gum and complete flaxseed kernels and flaxseed shells can be simultaneously obtained.

Description

technical field [0001] The invention relates to a method for producing linseed gum and linseed kernels, belonging to the technical field of storage and processing of agricultural products. Background technique [0002] Flaxseed is an oil rich in a variety of functional substances, such as the well-known linseed oil with high α-linolenic acid and health functions, natural plant gum linseed gum, and lignans that have been proven to have anti-cancer functions Wait. Therefore, a lot of research work has been carried out around the development of biologically active or functional products, and a number of processing technologies that can be put into industrial applications have been formed, such as cold pressing oil production and refining technology, linseed gum production technology, etc. Through the understanding of the existing linseed processing industrialization technology, it is found that there are still imperfections in the existing linseed processing, especially in the...

Problems solved by technology

In terms of flaxseed gum production technology, the existing technologies put into industrial production can be mainly classified into two types. One is the technology of producing flaxseed gum with blister gel represented by patent ZL00133515.4, which mainly uses flaxseed as raw material. Hot water leaching, separation, concentration / dehydration, drying to obtain linseed gum, the linseed gum produced by water foam glue has high viscosity because of its high purity, but an indisputable fact is that the production consumption is particularly high. The oil needs to be dried and pressed, and the quality of the pressed linseed oil is poor, and it is generally reflected that the linseed oil squeezed out in this way has a bitter and pasty taste; the other is the dry extraction of linseed oil represented by patents ZL99107952.3 and ZL99121012.3 Seed gum technology, after extracting flaxseed oil, separate the flaxseed skin from the cake, or separate the flaxseed skin after crushing the flaxseed, and then crush the flaxseed skin to a certain fineness to obtain the flaxseed gum. The consumption of linseed gum produced by this technology is very low, and it is easy to realize, but the product linseed gum contains a large amount of cellulose in the skin, so the viscosity of the product is not high
