Problems solved by technology

[0004] Because fresh Polygonatum has astringent and throat-stinging sensations, in order to solve its unpleasant taste in food, nine steaming and nine-drying methods and honey soaking methods are generally used to remove the astringent and throat-stinging sensations, but this method is complicated to operate and has limited effects

Embodiment 1

[0037] In September 2013, fresh Rhizoma Polygonatum was excavated from Xupu, Huaihua City, Hunan Province, and processed according to the following steps to obtain Deastringent Rhizoma Rhizoma Polygonatum Tablets.

[0038] (1) Sorting: remove moth-eaten, moldy and degenerated parts, soil, sand, and other plant materials and other impurities.

[0039] (2) Cleaning: First, rinse with tap water to remove the sediment on the surface, then use a brush to repeatedly scrub the surface of Polygonatum, paying special attention to scrubbing the sunken areas until the sediment and muddy smell are completely washed away.

[0040] (3) Slicing: Drain the washed Polygonatum a little, cut it into slices of Polygonatum with a thickness of about 2-4mm with a knife on a clean chopping board or with a slicer.

[0041] (4) Hardening: Put the cut Polygonatum slices in a clean plastic bucket, and prepare 0.5% CaCl with distilled water 2 Soaking in the solution requires the solution to cover all the...

Abstract

The invention discloses an astringency removal method for polygonatum sibiricum and polygonatum sibiricum slices obtained by the method. The method comprises the following steps: (1) hardening: soaking polygonatum sibiricum crude slices into a CaCl2 solution with the mass concentration of 0.1-1.0% for 5-60 minutes; (2) protecting the color: soaking the hardened polygonatum sibiricum slices into a mixed solution of NaHSO3 with the mass concentration of 0.02-0.50% and citric acid with the mass percent of 0.02-0.50% for 5-60 minutes; and (3) removing astringency: putting the color-protected polygonatum sibiricum slices into a beta-cyclodextrine solution with the mass concentration of 0.1-1.0%, and carrying out astringency removal for 0.2-3.0 hours. The main activity of the polygonatum sibiricum slices prepared by the method can be maintained to be more than 98%; the polygonatum sibiricum slices have no astringency and throat irritating feeling, and have the unique flavor of the polygonatum sibiricum; the polygonatum sibiricum slices can be directly processed into foods and can also be used as manufacturing raw materials of other foods; the polygonatum sibiricum slices have high medical and health-care functions.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for removing the astringency of Polygonatum and obtained Polygonatum Tablets. Background technique [0002] Polygonatum Polygonatum, also known as Tiger Ginger and Chicken Head Ginseng, is the rhizome of Polygonatum Polygonatum, Polygonatum Polygonatum or Polygonatum Polyflora of Liliaceae, and belongs to the homologous plant of medicine and food. my country's Hebei, Inner Mongolia, Shaanxi, Yunnan, Guizhou, Guangxi, Hunan, Anhui and Zhejiang are rich in Polygonatum resources. Polygonatum is rich in nutrients, and its rhizome contains niacin, mucilage, quinones, polysaccharides A, B, and C of Polygonatum (all composed of glucose, mannose, and galacturonic acid), Polygonatum oligosaccharides A, B, and C ( Both are composed of glucose and fructose), and also contain 11 kinds of amino acids such as lysine. Polygonatum polysaccharide is the main bioactive component...
