Embodiment 1

[0024] An additive for tobacco leaf planting capable of increasing the polysaccharide content is obtained by the following preparation method:

[0025] ① Cleaning: Wash the discarded lychee skin with water to remove the sediment and impurities on the surface of the lychee skin;

[0026] 2. Drying: drying the lychee skin obtained in step 1, and pulverizing it with a ball mill to obtain 80 orders of litchi skin coarse powder;

[0027] ③Low-temperature pulverization: The litchi skin coarse powder obtained in step ② is subjected to low-temperature freezing at 0°C and low-temperature sublimation drying in sequence, then uses liquid nitrogen as the grinding medium, and uses an ultra-low temperature pulverizer for low-temperature pulverization at -80°C;

[0028] ④High-pressure homogenization: Add 5 times the weight of pure water to the material obtained in step ③ and mix evenly, then add it to a high-pressure homogenizer for processing, 10000psi, 20min, centrifuge, 8000r / min, 10min, ...

Embodiment 2

[0030] An additive for tobacco leaf planting capable of increasing the polysaccharide content is obtained by the following preparation method:

[0031] ① Cleaning: Wash the discarded lychee skin with water to remove the sediment and impurities on the surface of the lychee skin;

[0032] 2. Drying: drying the lychee skin obtained in step 1, and pulverizing it with a ball mill to obtain 100 order litchi skin coarse powder;

[0033] ③Low-temperature pulverization: The litchi peel coarse powder obtained in step ② is subjected to low-temperature freezing at -10°C and sublimation drying at low temperature in sequence, and then liquid nitrogen is used as the grinding medium, and low-temperature pulverization is carried out at -100°C with an ultra-low temperature pulverizer;

[0034] ④High-pressure homogenization: Add 6 times the weight of pure water to the material obtained in step ③ and mix evenly, then add it to a high-pressure homogenizer for processing, 15000psi, 15min, centrifug...

Embodiment 3

[0036] An additive for tobacco leaf planting capable of increasing the polysaccharide content is obtained by the following preparation method:

[0037] ① Cleaning: Wash the discarded lychee skin with water to remove the sediment and impurities on the surface of the lychee skin;

[0038] 2. Drying: drying the lychee skin obtained in step 1, and pulverizing it with a ball mill to obtain 100 order litchi skin coarse powder;

[0039] ③Low temperature pulverization: The litchi peel coarse powder obtained in step ② is subjected to low-temperature freezing at -18°C and sublimation drying at low temperature in sequence, then liquid nitrogen is used as the grinding medium, and low-temperature pulverization is carried out at -120°C with an ultra-low temperature pulverizer;

[0040] ④High-pressure homogenization: Add 5 times the weight of pure water to the material obtained in step ③ and mix evenly, then add it to a high-pressure homogenizer for processing, 18000psi, 10min, centrifuge, 1...

Abstract

The invention discloses an additive for increasing the content of polysaccharide in tobacco leaf planting. The additive is prepared by using the following method: (1) cleaning: cleaning waste litchi rind shells with clean water, and removing mud and impurities on the surfaces of litchi rind shells; (2) drying: stoving the litchi rind shells obtained in step (1), and crushing to obtain crude litchi rind shell powder; and (3) lower-temperature crushing: performing lower-temperature freezing, and lower-temperature sublimation drying on the crude litchi rind shell powder obtained in step (2) in sequence, and then performing lower-temperature crushing in an ultralower-temperature grinding at 80-120 DEG C by taking liquid nitrogen as a grinding medium; and (4) high-pressure homogenizing: adding purified water into materials obtained in step (3) for mixing uniformly, putting in a high-pressure homogenizing machine for treating, centrifuging to obtain slag, adding purified water into the slag for high-pressure homogenizing again, centrifuging, combining supernate, and drying to obtain the additive in tobacco leaf planting. The additive can be used for improving every quality index in tobacco leaf planting obviously and meeting planting demands of high-grade tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf planting, in particular to an additive for tobacco leaf planting capable of increasing the polysaccharide content. Background technique [0002] my country is a big tobacco planting country. The tobacco leaves obtained from planting will be graded. According to the quality characteristics of different parts of the tobacco leaves, the color of the same part of the tobacco leaves after modulation reflects the internal quality. According to the maturity of the tobacco leaves, leaf structure, oil content, chroma, Graded by length. After grading, a large amount of low-grade tobacco leaves need to be processed and utilized urgently every year, otherwise it will cause environmental pollution and waste of resources. [0003] Chlorogenic acid is one of the most abundant and important polyphenolic compounds in tobacco. It is a phenylpropanoid compound produced by shikimic acid pathway in the process of...
