Problems solved by technology

But it cannot be eaten directly among the people, and only a small part is used as feed, alginate, beverage and raw material in the pharmaceutical industry. Most of the sargassum has not been well utilized, and its development and utilization value is low

Abstract

A process for extracting edible fibres from sargassum includes such steps as washing, cutting, immersing, extracting by sodium carbonate, filter, neutralizing, filtrate, adding calcium chloride to obtain gel, bleaching with sodium hypochlorite, activating, dewatering, baking, pulverizing to obtain soluble edible fibres, treating the filtered dregs with acid or alkali, bleaching, dewatering, baking, pulverizing to obtain insoluble edible fibres, and proportionally mixing soluble with insoluble edible fibres (4:1).

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 sargassum. Background technique [0002] Dietary fiber has many important physiological functions for human health, which has been confirmed by a large number of research facts and epidemiological findings at home and abroad, and has been confirmed by modern medicine and nutrition as the "seventh nutrient" alongside the traditional six major nutrients. ". However, due to the dietary fiber extracted from different raw materials, its composition is very different, and its physiological function is also very different. At present, the raw materials used to extract dietary fiber at home and abroad mainly come from land plants such as cereals, beans, bagasse and vegetables. Its functional index is low and its physiological activity is poor. [0003] Sargassum is mainly produced in coastal areas such as Guangd...
