Description
The present invention relates to the production method of a kind of kudzuvine root starch (pueraria starch), especially a kind of industrialized preparing process of kudzuvine root starch.
Pueraria lobota, formal name used at school Pueraria Lobata, the long-term vine of pulse family.Kudzuvine root starch has refrigerant refrigerant effect, and is among the people as a kind of food consumption.The root of kudzu vine also is the food of the dietotherapeutic of Ministry of Health's approval.In addition, also can be kudzuvine root starch as foodstuff additive, make that noodles containing root of kudzuvine, Pueraria lobota bread, arrowroot vermicelli, Pueraria lobota freeze, Pueraria lobota ice-creams etc., very popular.
Long ago, folks of china just has family workshop type to produce the method for kudzuvine root starch.The main component of the root of kudzu vine is starch and Mierocrystalline cellulose, also contains Flavonoid substances etc.The artificial culture root of kudzu vine is based on starch, and content can reach (dry weight) more than 70%, and the wild root of kudzu vine has two kinds: a kind of Chai Ge of being called, and based on Mierocrystalline cellulose, starch content only is 15%～20% (dry weight); Another kind is called Pachyrhizua angulatus, and starch content can reach 20%～60% (dry weight).In addition, the general silt in root of kudzu vine surface is more, therefore original family workshop type production technique is exactly after the root of kudzu vine is cleaned, pulverizes, to clean repeatedly with clear water, and starch is come out from the Pueraria lobota slag, remaining mainly is root of kudzu vine fiber, the amylum marantae solution of wash water is through long-time precipitation, and then washing removes silt, repeated precipitation again, sun drying is finished product then.A lot of peasant's familys are to make to produce kudzuvine root starch in this way in the Hunan, and its production efficiency is low, and tooling cost is very high, the kudzuvine root starch rate of recovery very low [less than 50% (dry measure) of pueraria starch content].
Other has some bigger producers, can process 20 tons～30 tons kudzuvine root starch as 1 year, also is the aforementioned production method of continuing to use basically, only adopts bigger factory building and settling tank.Chinese patent application 93104516 (publication number: be to adopt this traditional family workshop type production technique to make kudzuvine root starch fully CN1093877A).Pueraria starch is in different content differences in season, and general is the duration that adds of kudzuvine root starch in the March in November to next year, and root of kudzu vine prematurity or starch do not form as yet in a large number before this; After this, surpass the root of kudzu vine ripening stage, kudzuvine root starch is consumed to utilize gradually is converted into sugar.Therefore, pueraria starch to add the duration shorter, the output that improves kudzuvine root starch is a big bottleneck of restriction pueraria starch processing development.And traditional kudzuvine root starch factory, even maximum traditional kudzuvine root starch factory, its annual production is at most less than 50 tons.And traditional workshop-based production method is because the main technologies such as cleanings, precipitation that adopt, and much starch are stayed in the root of kudzu vine slag or discarded with silt, cause its rate of recovery can only reach about 50% even lower, have greatly wasted root of kudzu vine resource.Its production cost per ton also very high (13000 yuan/ton～14000 yuan/ton).
The kudzuvine root starch preparation technology that Chinese patent application 99118769 (publication number CN1247714A) is announced, adopt centrifuging process that the scum silica frost in the Pueraria lobota slag is removed, but the Mierocrystalline cellulose that proportion is bigger etc. can not be removed well, and therefore the kudzuvine root starch cellulose of preparation is higher, and mouthfeel is more coarse.In addition, the dry employing of the kudzuvine root starch of traditional production method Exposure to Sunlight, its efficient is low, the time is long, and loses the quality that a part of nutritive ingredient (as flavones isoreactivity composition) influences the kudzuvine root starch product.
