Embodiment 1

[0019] ⑴Water extraction

[0020] Take Sichuan yellow ginger tubers (old ginger, purchased from the market, without any treatment, the water content is 58.9%) 10Kg, without peeling and washing, cut into 1-2mm thin slices, and put them into a beater for beating.

[0021] Filter the slurry after beating with a 400 sieve to obtain filtrate A1 and filter residue B1.

[0022] ⑵ Filtrate A to ginger paste powder C1

[0023] Send the filtrate A into a three-effect energy-saving concentrator to concentrate to a clear paste with a relative density of 1.16-1.18 (measured at 60-65°C), and let it cool. The concentration temperature is 50-60°C, and the vacuum degree is -0.01 - -0.06Mpa.

[0024] The concentrated clear paste is spray-dried. Spray drying drying temperature 85-90 ℃, drying time 90 minutes.

[0025] After drying, pulverize with a pulverizer to obtain 0.10 Kg ginger paste powder C1, and the pulverizer screen is 60 mesh.

[0026] (3) Filter residue B1 to filter residue B2 ...

Abstract

Relating to processing of an agricultural product, the invention discloses a method for extraction of effective components in ginger. The method comprises the steps of: (1) water extraction: taking a tuber of Sichuan small turmeric, cutting it into 1-2mm slices, putting the slices into a beater to undergo beating, filtering the beaten slurry with a 400 sieve to obtain a filtrate A1 and a filter residue B1; (2) preparation of the filtrate A into ginger paste powder C1: sending the filtrate A into a triple-action energy-saving concentrator to concentrate it into a clear paste to perform spray drying, and then conducting smashing to obtain the ginger paste powder C1; (3) preparation of the filter residue B1 into filter residue B2; (4) preparation of the filtrate A2 into ginger essential oil D1: subjecting the filtrate A2 to reduced pressure distillation to remove ethanol, thus obtaining the ginger essential oil D1; and (5) preparation of the filter residue B2 into ginger starch and ginger powder. Compared with the prior art, the method provided in the invention has a high extraction rate to the effective components in ginger.

Description

technical field [0001] The invention relates to an extraction of agricultural products, in particular to an extraction method of active ingredients in ginger. Background technique [0002] Ginger is an edible and medicinal plant. It is planted in many parts of the country. The ginger harvested before and after "Bailu" is used to be called "new ginger" and "young ginger"; the ginger of the next year is called "old ginger", which is better for medicinal purposes. There are small species of ginger, large species of ginger, mountain ginger (wild ginger) and other varieties. It is better to use small species of ginger for medicinal purposes. It is customary to call small species of ginger "little yellow ginger". , fragrant, fine fiber. Dazhong ginger has a greyish-yellow iron-colored complexion when cut, thicker fibers, less pungent and fragrant than small species of ginger, and poor medicinal efficacy. There is also a kind of ginger that is between Dazhong ginger and Xiaozhon...
