Problems solved by technology

[0006] Judging from the current patents and literature reports, the utilization of chestnut bracts still remains at the level of development of some single products, and comprehensive utilization in the true sense has not yet been formed. Now every chestnut harvest season, a large amount of chestnut bracts are thrown away. The wilderness causes pollution and waste. Therefore, it is of great significance to establish a clean, efficient and pollution-free ecological industrial chain of chestnut bract resources to maximize the utilization of chestnut bract resources, which is beneficial to the country and the people.

Embodiment Construction

[0027] Example 1 of this program.

[0028] 1. Put the crushed chestnut bract dry powder and deionized water with a pH value of 8 into the tank at a solid-to-liquid ratio (by weight) of 1:10, stir and extract for 20 minutes, set the temperature in the tank to 55°C, and start The microwave generator outside the tank radiates microwaves with a power density of 50W / g to the stirred material in the tank for about 2 to 6 minutes, so that the material can be heated up to 55°C rapidly (the precise time of radiation is automatically regulated by the intelligent monitor according to the measured temperature), After heat preservation and leaching for 10 minutes, the material is taken out of the tank for solid-liquid separation.

[0029] 2. Put the filter residue after the first water extraction into the tank again, add new PH8 deionized water according to the solid-to-liquid ratio of 1:8, set the temperature in the tank to 60°C, repeat the above microwave radiation and heat preservation ...

Abstract

The invention relates to a co-production method of polyphenols, pigments, tannin, procyanidins and wood powder through Chinese chestnut buds. Chinese chestnut buds are smashed into 30-80 meshes, Chinese chestnut bud powder and alkaline deionized water are added into a tank, subjected to microwave radiation and stirred and extracted for three times, a water extract solution is separated through various films, polyphenols, pigments, tannin, procyanidins and wood powder are obtained after concentration and drying, and filter residues are dried into wood powder. By means of the scheme, comprehensive utilization of waste Chinese chestnut bud resources can be achieved, and the method belongs to the clean and efficient pollution-free ecological mode industry.

Description

technical field [0001] The invention belongs to the field of biochemical technology, and relates to the comprehensive utilization technology of natural biomass resources, in particular to a method for co-producing polyphenols, pigments, tannins, proanthocyanidins and wood powder by using discarded chestnut bract resources (including millet husks and millet clothes) new method. Background technique [0002] Chestnut is the fruit of the economic tree of the family Fagaceae, Millet. It is delicious and rich in nutrients and trace elements beneficial to the human body. It is one of the nuts that people love. my country's chestnut resources rank first in the world, with an annual output of more than 1 million tons, accounting for more than 75% of the world's total output. The chestnut bract is the thorny shell of the chestnut, the chestnut shell is the inner hard shell of the chestnut, and the chestnut coat is the seed of the chestnut kernel. The three kinds of skins together acc...
