(1) technical field
The present invention relates to a kind of improvement of multiple-purpose project of seaweed chemical, specifically is to utilize to carry the sea-tangle waste is produced behind the glue sea-tangle meals with fiber and production method thereof.
(2) background technology
At early eighties, China was having report aspect the physiological function of dietary fiber, but furtherd investigate and large-scale production always.Successively report is arranged: utilize wheat bran, soybean, beet, mushroom, bagasse and Pericarpium Kaki etc. to extract the research of dietary fiber, and in subrange, obtained large-scale production.At present, the research overwhelming majority of China's dietary fiber rests on the terrestrial plant aspect, and in marine field, especially marine alga tang resource is researched and developed dietary fiber of high activity, in the still initiative research work of China.
The annual production of China's algin has at present reached more than 10000 tons, leaps to the second place of the world.Kelp processing waste accounts for 1/3rd of total output, enormous amount.Obviously, comprehensive utilization sea-tangle resource is developed the new active substance in the sea-tangle, widens the range of application of sea-tangle resource, is to solve a low important channel of laminaria culture benefit.The discarded object of sea-tangle processing is promptly put forward the kelp residue of discarding behind the glue by sea-tangle, and its main component is: include the cellulosic total fiber element 70% of water-soluble cellulose and water-insoluble, protein 8%, algal polysaccharides 5%, other composition 17%.These active components are extracted separation and purification, and carry out the physiological function activity test, it is further laid the foundation for basic material and the product that is developed to medicine, food, fine chemistry industry and feed.
Dietary fiber (Dietary Fiber is called for short DF) means the general name that is difficult to by the high molecular polysaccharide material of enzymic digestion in human body.Dietary fiber has different physiological roles and effect, is to maintain one of requisite nutritional factors of the healthy institute of human body, and also be the desirable functional health raw-food material of a class, so dietary fiber has obtained to use widely in world's food industry.The application of dietary fiber in bakery product is more extensive, and the biggest market of west dietary fiber food surely belongs to.Select the kind of dietary fiber to consider from the following aspects: one, physiologically active is good, can keep the fragrance and the local flavor of food; Two, certain expansion character is arranged, have good water-retaining property and oil absorption; Three, human body is had no adverse effects; Four, raw material sources are abundant, and production cost is low.The dietary fiber of generally selecting for use at present is a wheat bran fiber, and its mouthfeel, fragrance behind food prepared therefrom is all better, but the wheat bran color is darker, and water-soluble fibre content is high not enough, and process some cake has certain influence.Dietary fiber has a lot of important physical functions to health, and this is confirmed by domestic and international a large amount of research and epidemiology survey results, and is thought and traditional six big nutrients " the 7th nutrient " arranged side by side by modern medicine and nutrition.Though dietary fiber can not be digested and assimilated in human body, have multiple special function and physiological action, people healthy played a part very important.
So far, there is no both at home and abroad, extract dietary fiber the relevant kelp residue after carrying glue, and be used to produce the report of health food.Along with improving constantly of living standards of the people, meticulous food variety increases gradually, meat and vegetarian diet be disequilibrium gradually, the intake of dietary fiber reduces just day by day that (average content of food fiber is 3% in the vegetables, people reach 16～24g/ people d ingestion standard of WHO regulation far away by edible vegetable), the ciril disease that the meals imbalance causes (obesity, hypertension, diabetes etc.) has occurred, and this situation seems serious especially in the relatively advanced coastal cities of economy.Therefore, fully develop huge dietary fiber resource in the kelp processing waste, it is turned waste into wealth, and provide quality raw materials for food industry, this is for the diet structure of improving people, improve the whole people's the general level of the health, improve the aquatic products functional food at home and abroad the competitiveness on the market extremely important realistic meaning is arranged.
