Embodiment 1

[0035] The preparation method of high resistant starch instant whole lotus root powder specifically comprises the following steps:

[0036] 1) Cleaning: Select white fresh lotus root with no rot and deterioration, no serious rust spots in the hole, and complete joints, and use a soft brush to clean the dirt and other dirt on the surface in running water;

[0037] 2) Peeling: After cleaning the lotus root, first use a stainless steel knife to remove the joints, and then use a stainless steel knife to peel the skin. The peeling should be clean, thorough, smooth, remove mechanical damage and spots, etc., and then rinse with clean water;

[0038] 3) Slicing: Slice the peeled lotus root obtained in step 2) manually with a knife, and the thickness of the slice is about 0.5cm;

[0039] 4) Color protection: Immediately put the lotus root slices into the color protection solution (0.30wt% phytic acid + 0.25wt% citric acid + 0.25wt% ascorbic acid) after slicing, and the treatment time i...

Abstract

The invention belongs to the technical field of food and particularly discloses instant whole lotus root powder containing highly-resistant starch and a preparation method of the instant whole lotus root powder containing the highly-resistant starch. The preparation method includes subjecting fresh lotus roots taken as a raw material to washing, peeling, slicing, color protection, pulping and cryogenic grinding so as to obtain fresh lotus root pulp; subjecting the fresh lotus root pulp to limited-enzyme hydrolysis-drum drying, crosslinking adsorption, complexing, vacuum drying, grinding, blending, extruding granulation, sieving and packaging so as to obtain the instant whole lotus root powder containing the highly-resistant starch. The instant whole lotus root powder containing highly-resistant starch and the preparation method have the advantages that since embedded crosslinking, complexing, enzymatic debranching treatment and drum drying are combined to be applied to a whole lotus root powder production process, reconstituability of the whole lotus root powder can be improved, liquidity and solubility of the whole lotus root powder can be increased, resistant starch content in the whole lotus root powder can be increased, and the whole lotus root powder can have a certain effect on intestinal microecological balance regulation and gastrointestinal function improvement; powder granules produced by extruding granulation are uniform, loose and porous and can swell and gelatinize within short time, and accordingly the whole lotus root powder is excellent in instant solubility and wettability.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a high-resistant starch instant whole lotus root powder and a preparation method thereof. Background technique [0002] Lotus root, also known as lotus root, is the hypertrophic rhizome of lotus, an aquatic plant of Nymphaeaceae. It is mainly distributed in some southern provinces such as Fujian, Zhejiang, Guangdong, and Hunan. It is an important aquatic vegetable in my country.
