Abstract
The invention relates to a technology for extracting dietary fiber from kelp, comprising the following steps: washing, drying and crushing a kelp raw material, carrying out enzymolysis on a kelp powder with compound enzyme, treating the kelp powder with hydrochloric acid, extracting the kelp powder which has undergone enzymatic treatment and acid treatment by the use of sodium carbonate, filtering to obtain a filtrate and filter residue, neutralizing the filtrate, adding calcium chloride gel, treating the filter residue with sodium hydroxide and hydrochloric acid, merging the gel and the filter residue, bleaching with sodium hypochlorite, activating, dehydrating, drying and crushing so as to obtain the dietary fiber. According to the invention, soluble dietary fiber and insoluble dietary fiber of kelp are simultaneously utilized, outlet problem of leftovers obtained during processing of kelp is solved, and physiological function and use value of kelp are enhanced by changing a processing method of kelp.
Description
Technical field
One's duty invention relates to a kind of production technology extracting dietary fiber, particularly relates to the production technology that a kind of technique extracts kelp dietary fiber.
Background technology
dietary fiber is the compound mixture of a class polymer, is the class important foodstuffs nutrient needed for human digestive process.Much research shows, dietary fiber is in colon cancer, and hypercholesterolemia, has positive role in coronary heart disease and other multiple chronic disease controls.And the quality of physiological function of diet fiber, except having certain relation with processing method, depend on the source of raw material to a great extent, the beans of current use, cereal, the dietary fiber that the land based vegetation such as bagasse and vegetables raw material extracts, its its functional attributes is low and physiologically active is poor.Sea-tangle is a kind of large ocean economic algae of China, and its output accounts for the half of world wide production.The sodium alginate that kelp Rich contains, marine alga carbohydrate gum, marine alga starch, sweet mellow wine, cellulose, hemicellulose, biotin and mineral matter etc. are the quality raw materials extracting dietary fiber of high activity.
Summary of the invention
The object of the invention is to provide a kind of technique to extract dietary fiber in sea-tangle.Processing step is as follows:
Sea-tangle raw material is through cleaning, crushed after being dried, with HCl treatment after Kelp Powder complex enzyme zymohydrolysis, the Kelp Powder sodium carbonate after enzyme and acid treatment extracts, filter after be divided into filtrate and filter residue, in filtrate and after add calcium chloride gel, filter residue NaOH and HCl treatment, merge solidifying body and filter residue sodium hypochlorite bleaching, then activated, dehydration, dry, pulverize and obtain dietary fiber.
Specific embodiments
Cleaned by sea-tangle raw material, after drying, pulverize for subsequent use, Kelp Powder with complex enzyme zymohydrolysis after one hour, then adds the 0.1mol/L HCL solution normal temperature process 2 hours of 12 times amount.Clean through acid-treated Kelp Powder, drain moisture, filter after adding suitable quantity of water dilution after extracting with sodium dioxide, be divided into filtrate and filter residue.Filtrate regulates pH to neutral with watery hydrochloric acid, adds the calcium chloride solution of 7 times amount, stirs, gel 20 minutes, filters and cleans gel.Filter residue first boils with the sodium hydroxide solution of 5 times amount and processes half an hour, filter alkali lye, clean, squeeze and to anhydrate point, merge the sodium chloride solution that solidifying body and filter residue add 30 times, bleaching 30 minutes under alkalescence, elimination bleaching liquid, be washed till colloid without chlorine flavor, pulverize after 50 degree of vacuum drying, obtain sea-tangle dietary fiber of high activity.
Claims (5)
