Problems solved by technology

[0005] At present, there is a ginger powder called "Fenfenxiang" on the market, which is made by ultrafine grinding, grinding and drying technology. Although this method is simple, the particle size of the obtained ginger powder is relatively large, and its particle size is uneven; secondly , the temperature is not easy to control during the production process, resulting in the loss of active ingredients in ginger; in addition, it is easy to stick to the wall of the pulverizer during the production process, resulting in waste of ginger powder

Embodiment 1

[0033] The preparation of embodiment 1 superfine ginger powder

[0034] Include the following steps:

[0035] (1) fresh ginger 60kg cleaned with water is cut into thick ginger slices of 3mm, for preventing ginger from browning, blast drying at 40°C to moisture content is 6% immediately after sectioning, obtains 3kg dried ginger slices;

[0036] (2) Coarse grinding: Grinding the dried ginger slices into 120 mesh ginger coarse particles with a particle size of 20 DEG C with an RT silent grinding grinder (Beijing Tianyuan Huanya Machinery Grinding Co., Ltd.);

[0037] (3) Ultrafine pulverization: 220g of ginger coarse particles and the air after cooling and drying are jointly injected into the ultrafine pulverizer, and 200g of particle size is made of 1600 mesh ultrafine ginger powder by adopting high-speed airflow pulverization, and the process parameters are after freeze-drying The pressure of air injected into the ultrafine pulverizer is 1.0MPa, the working pressure of the su...

Embodiment 2

[0040] Embodiment 2 ginger powder solubility test

[0041] Test materials: Weigh dried ginger, and then use FDV liquid nitrogen cooling pulverizer (produced by Beijing Tianyuan Huanya Machinery Pulverization Equipment Co., Ltd.) to prepare ginger powder with a particle size of 50, 120, 200 and 400 mesh. The 1600 purpose superfine ginger powder of embodiment 1 gained.

[0042] Experimental method: Accurately weigh 5g each of ginger powder with a particle size of 50, 120, 200, 400 mesh and the 1600 mesh ultrafine ginger powder obtained in Example 1, then place in 100ml water to prepare ginger powder milk, and take 20ml of 5% ginger powder The powdered milk was stirred and heated at 80°C, and the solubility was measured under the conditions of 10, 20, 30, 40, 50, and 60 min, respectively. Calculate its solubility according to the following formula:

[0043]

[0044] A - Amount of Ginger Powder Dissolved

[0045] W - weight of ginger sample

[0046] Results (such as figur...

Embodiment 3

[0047] Embodiment 3 Ginger powder protein solubility comparative test

[0048] According to the principle of combining Coomassie brilliant blue G250 with protein established by Bradford in 1976, a method for rapid and sensitive quantitative determination of protein was established. Weigh each 10g of the 50, 120, 200, 400, 1600 mesh ginger powder obtained in Examples 1 and 2, place them in 40ml water, shake and extract at 45°C, and measure the conditions of 10, 20, 30, 60, 90min at different times lower solubility.

[0049]

[0050] S-Ginger Powder Dissolved Protein Content

[0051] C-Protein content in raw materials of ginger powder

[0052] Results (such as image 3 ) shown. The protein solubility of ultrafine ginger powder is higher than that of ordinary ginger powder, which shows that the ultrafine grinding of ginger is beneficial to improve the dissolution rate of protein.

Abstract

The invention discloses an ultramicro ginger powder processing method; the ultramicro ginger powder refers to the ginger powder with 700mesh to 2000mesh of grain size. The production method comprises the steps: raw material selection, slicing, drying, coarse grinding, ultramicro grinding, sterilization, packaging, etc. The method changes the traditional ginger grinding and processing technologies, injects the coarse ginger particles after coarse grinding into an air flow ultramicro grinding machine to prepare ultramicro powder by pressure or impulsion. The method solves the problems of the resource waste and poor solubility in the traditional ginger grinding processes; after the ultramicro grinding, the ginger powder has the advantages of high release speed of effective components, large release amount, convenient and fast use method, even distribution, etc., and is suitable to be promoted and applied in food, feed, cosmetics, health care and other industries.

Description

technical field [0001] The invention belongs to the field of agricultural product processing, and in particular relates to a superfine ginger powder and a production method thereof. Background technique [0002] Ginger (Zingiber officinale Roscoe) contains a large number of active ingredients with flavor substances and health effects, such as gingerol, zingerone, shogaol, gingerol, multivitamins, protease, cellulose, etc. Therefore, regular consumption of ginger has the functions of attracting food, detoxifying, promoting the development of digestive tract and enzyme system, anti-oxidation, and anti-aging. Because ginger has edible and medicinal value and has a wide range of applications, the demand for ginger is also increasing year by year. However, due to the low yield of biologically active components such as gingerol and zingiberone, and the high cellulose content, it is difficult to pulverize, and these problems restrict the utilization of ginger resources. [0003] ...
