Embodiment 1

[0022] A preparation method of pearl yellow konjac powder, comprising the steps of:

[0023] (1) After sorting, cleaning, and peeling the raw materials, slice and protect the color; the color protection is: add the slices to water, then add sulfurous acid, and soak for 30-40min; the amount of sulfurous acid added is: 2.5g sulfurous acid: 1kg konjac slices;

[0024] (2) Wash the color-protected slices with decolorization treatment for 30-90 minutes; the decolorization treatment is to add 5% hydrogen peroxide of the mass of the slices, soak for 1 hour at a temperature of 40° C., and a pH value of 9-10. After soaking, Wash twice with water, then soak in water, add decolorized activated carbon to the water for adsorption, filter and separate, and obtain decolorized slices;

[0025] (3) After washing the decolorized slices with ethanol, grind them into a slurry; add a dilution aid during the grinding process; the amount of the dilution aid is 1 kg of slices: 250 ml of the dilution...

Abstract

The invention discloses a preparation method of an amorphophallus bulbifer refined powder, and belongs to the field of konjak starch processing. The preparation method of the amorphophallus bulbifer refined powder includes the steps: (1), after being sorted, washed and peeled, a raw material is sliced and then subjected to color protection; (2), after color protection, obtained slices are washed with water and then subjected to decolorizing treatment for 30-90 min; (3), decolorized slices are washed with ethanol and then are grinded to form a pulp; and (4), the pulp is washed with water and precipitated, ethanol is used for removing impurities, washing is conducted again, microwave vacuum drying and sieving are conducted, and the amorphophallus bulbifer refined powder is obtained. According to the preparation method of the amorphophallus bulbifer refined powder, hydrogen peroxide and decolorizing activated carbon are utilized for carrying out comprehensive decolorizing twice, and thusthe whiteness of the amorphophallus bulbifer refined powder can be effectively increased; during pulp preparation, a dilution additive is additionally adopted, an anionic surfactant serves as the dilution additive, thus, the amorphophallus bulbifer refined powder (starch) can be effectively prevented from expanding, meanwhile, brownness is effectively prevented, decolorizing is further conducted,and the whiteness is increased by about 10%, so that significant progress is made; and the dilution additive is safe and reliable.

Description

technical field [0001] The invention relates to the field of konjac starch processing, in particular to a preparation method of bulbil yellow konjac powder. Background technique [0002] Konjac has two functions of medicine and food, and has preventive and auxiliary therapeutic effects on cardiovascular, digestive tract and other diseases. The main component of konjac flour is polymer polysaccharide, which is polymerized by glucomannose β-1,4 glycosidic bonds. It is a high-quality fluid fiber. During the planting process of flower konjac and white konjac, pests and diseases are prone to occur, which affects the yield. Amorphophallus konjac is a large-scale konjac with strong stems and large leaf area. The surface diameter of the whole leaf can reach about 1.5 meters after stretching, and the plant height can reach 2 meters. Annual tubers weigh 4-6 kg. Generally, the output per hectare is 30 tons, and the high one can reach more than 60 tons. The content of glucomannan in...
