Abstract

The present invention relates to a method for preparing lobed kudzuvine root starch from lobed kudzuvine root. The method comprises: selecting high-quality lobed kudzuvine root as a raw material, cleaning, and carrying out a water addition and slurry grinding treatment to obtain a lobed kudzuvine root slurry mixture; sequentially adding cellulase and pectinase to the lobed kudzuvine root slurry mixture, and controlling conditions to carry out hydrolysis; carrying out filtering, precipitation and separation on the enzymolysis mixing solution through a filtration cloth, taking the starch precipitate, adding hydrogen peroxide, and controlling conditions to carry out a bleaching treatment; filtering to obtain wet starch; and carrying out low temperature vacuum drying to obtain the lobed kudzuvine root starch finished product. The method has characteristics of rational process, simple operation, short production cycle, no environmental pollution, high starch extraction rate, and high starch whiteness.

Description

technical field [0001] The invention relates to the preparation of starch derived from plants, in particular to a method for preparing kudzu starch from kudzu root. Background technique [0002] We know that Lobed Kudzuvine Root is the tuber of the vine plant Pueraria mirifica. Pueraria lobata is rich in starch and flavonoids (namely daidzin, puerarin, puerarin), and has high food value and medical and health value . my country's Ministry of Health announced in 1988 that it is both edible and medicinal plants, and the planting area has developed rapidly in recent years. [0003] Pueraria lobata is the underground organ of kudzu, which is more developed and is the main storage organ. It is rich in starch, with large and polygonal cells, no intercellular space, and less wood fiber than bast fiber. Pueraria lobata starch is extracted from Pueraria lobata root, which has certain health effects because it contains bioflavonoids. In recent years, kudzu root starch has been used...
