Abstract

The invention provides a preparation method of sargassum fusiforme dietary fiber. The method includes the steps of: drying, enzymolysis, acidolysis, alkaline hydrolysis, centrifugation, gelation, bleaching, drying, activation, alcohol dehydration and drying. The method provided by the invention employs a composite plant hydrolase to assist papain to extract sargassum fusiforme dietary fiber, greatly improves the protein hydrolysis rate of sargassum fusiforme, overcomes the disadvantage of poor one-time protein removal effect in common enzymatic method, effectively destroys cell walls, enhancesthe full permeation of a fiber crystalline area, completely releases part of the protein closely combined to residue, and is conducive to degradation of papain to protein so as to improve the productpurity.

Description

technical field [0001] The invention relates to a preparation method of hijiki highly active dietary fiber, in particular to a preparation method of hijiki dietary fiber. Background technique [0002] Hijiki belongs to the Phaeiophyta Sargassum family, which mainly grows in the warm temperate waters of the western North Pacific Ocean. Hijiki has long been used as medicine in the folk, and it has been included in the Chinese Pharmacopoeia together with the Sargasso plant Artemisia chinensis. Hijiki is rich in polysaccharides, crude fiber, vitamins and minerals, and contains 14 important trace elements necessary for the human body. It also has biologically active functions such as antibacterial, antiviral, anticancer, antioxidative, antimutagenic, anticoagulant, lowering blood pressure, lowering blood fat, and immune regulation. However, there is currently no suitable industrialized food processing technology for hijiki in my country, so most hijiki is mainly exported to Jap...
