Abstract

The invention discloses a process method for converting soybean hulls into dietary fiber, which solves the problem that existing soybean hulls transform dietary fiber into excessively high process temperature, and the obtained product has deep color, coarse particles, is not easy to bleach, has peculiar smell, and has poor taste , The problem of low fiber production. The technical scheme comprises that soybean hulls are coarsely ground with 2N edible HCl for acid hydrolysis, then washed with water until neutral, and then centrifugally dehydrated to obtain acid-lysis dehydrated particles; then the acid-lysis dehydrated particles are subjected to alkaline hydrolysis with 2N edible KOH, and then After washing with water to neutrality, centrifugal dehydration is carried out to obtain alkali hydrolysis dehydrated particles; finally, the alkali hydrolysis dehydrated particles are dried with hot air and then ground to fineness. The invention has the advantages of simple process, low production cost, good decolorization effect, no peculiar smell, good taste, good degradation effect, easy crushing and high fiber content.

Description

technical field

[0001] The invention relates to the field of food processing, in particular to a process for converting soybean hulls into dietary fiber. Background technique

[0002] Residue after soybean processing - soybean hulls are rich in fiber, pigments and other plant compounds, especially cheap and abundant high-quality dietary fiber resources. This type of dietary fiber can prevent constipation, detoxify and prevent cancer, and promote intestinal health, etc. It has multiple functions, and it has strong oil-holding, water-holding and volume-enhancing properties. It can be used in pastries, biscuits, puffed foods and various health drinks. It is an ideal natural additive and flour quality improver. Add it to Food can also improve water retention and shape retention of food, improve freeze-thaw characteristics, etc. The further processing of soybean hulls into dietary fiber is a subject that technical personnel are actively studying at present.
