Productive technology for extrating diet fiber from sea-tangle

Abstract

A process for extracting edible fibres from kelp includes such steps as washing, drying and pulverizing raw kelp, enzymolyzing, treating with hydrochloric acid, extracting by sodium carbonate, filter, neutralizing the filtrate, adding calcium chloride to obtain gel, treating the dregs with sodium hydroxide and hdyrochloric acid, mixing the said gel with the treated dregs, bleaching with sodium hypochlorite, activating, dewatering, baking and pulverizing.

Description

Technical field

[0001] The invention relates to a production process for extracting dietary fiber, in particular to a production process for extracting dietary fiber from kelp. Background technique

[0002] Dietary fiber is a complex mixture of polymers and is an important food nutrient required for human digestion. Many studies have shown that dietary fiber plays a positive role in the prevention and treatment of colon cancer, hypercholesterolemia, coronary heart disease and other chronic diseases. The physiological function of dietary fiber is not only related to the processing method, but also depends to a large extent on the source of raw materials. The dietary fiber extracted from land plants such as cereals, beans, bagasse and vegetables is currently used. Low functional index and poor physiological activity.

[0003] Kelp is a large marine economic algae in my country, and its output accounts for about half of the world's annual output. Kelp is rich in sodium algin...
