Embodiment 1

[0049] A preparation method of anti-glycation black tea extract, comprising the following steps:

[0050] (1) Withering: pick the fresh leaves of Yunnan big-leaf tea of ​​Yunkang No. 43, and spread the fresh leaves of Yunnan big-leaf tea on a bamboo mat with a thickness of 2 cm, a temperature of 25°C, and a time of spreading 8h, the bamboo mat is placed in a cool place to obtain the withered tea leaves;

[0051] (2) Kneading: the tea leaves after withering are carried out without pressurized rolling, the load per barrel is 35kg, the rotating speed of the kneading machine is 52 rpm, kneading in two times, once kneading for 30 minutes, spray the fermentation liquid, the fermentation The mass ratio of liquid to withered tea leaves is 1:50, and then kneaded for 15 minutes for the second time to obtain kneaded tea leaves;

[0052] (3) Fermentation: Spread the rolled tea leaves on a bamboo mat, cover them with pure cotton cloth, and carry out fermentation. The thickness of the spre...

Embodiment 2

[0059] A preparation method of anti-glycation black tea extract, comprising the following steps:

[0060] (1) Withering: pick the fresh leaves of Yunnan big-leaf tea of ​​Yunkang No. 43, and spread the fresh leaves of Yunnan big-leaf tea on a bamboo mat with a thickness of 2 cm, a temperature of 25°C, and a time of spreading 8h, the bamboo mat is placed in a cool place to obtain the withered tea leaves;

[0061] (2) Decaffeination: Place 1 part by weight of withered tea leaves in a tea dipping basket, immerse the tea dipping basket in 25 parts by weight of a 96°C caffeine removal solution for 30 seconds, then lift the tea dipping basket out , soaking in 25 parts by weight of water at 25°C for 30 seconds, bringing out the tea dipping basket, taking out the tea leaves, dehydrating the tea leaves at 3000 rpm for 6 minutes, to obtain decaffeinated tea leaves;

[0062] (3) Kneading: the decaffeinated tea leaves are kneaded without pressurization, the load per barrel is 35kg, the k...

Embodiment 3

[0073] A preparation method of anti-glycation black tea extract, comprising the following steps:

[0074] (1) Withering: pick the fresh leaves of Yunnan big-leaf tea of ​​Yunkang No. 43, and spread the fresh leaves of Yunnan big-leaf tea on a bamboo mat with a thickness of 2 cm, a temperature of 25°C, and a time of spreading 8h, the bamboo mat is placed in a cool place to obtain the withered tea leaves;

[0075] (2) freezing treatment: freezing the withered tealeaves at -8°C for 90 minutes, then thawing them at 25°C for 2 hours to obtain frozen-treated tealeaves;

[0076] (3) Decaffeination: Place 1 part by weight of frozen tea leaves in a tea dipping basket, immerse the tea dipping basket in 25 parts by weight of a 96°C caffeine removal solution for 30 seconds, and then take out the tea dipping basket , soaking in 25 parts by weight of water at 25°C for 30 seconds, bringing out the tea dipping basket, taking out the tea leaves, dehydrating the tea leaves at 3000 rpm for 6 mi...

Abstract

The invention discloses an anti-glycation black tea extract and a preparation method thereof. The preparation method comprises the following steps: (1) withering; (2) rolling; (3) fermenting; (4) drying; and (5) extracting. By adopting the anti-glycation black tea extract and the preparation method thereof, the anti-glycation black tea extract has rich nutrient substances and rich fragrance, has remarkable anti-glycation effect and anti-oxidation effect, and has a wide application group since caffeine is removed, and can be used for preparing health-protecting foods or used as cosmetic raw materials.

Description

technical field [0001] The invention relates to the technical field of product processing, in particular to an anti-glycation black tea extract and a preparation method thereof. Background technique [0002] French chemist Maillard L.C.Maillard discovered in 1912 that when glycine and glucose were mixed and heated, a brown substance would form, so the saccharification reaction is also called the Maillard reaction. Glycation in the human body is similar to the above-mentioned Maillard reaction, and the saccharification reaction in the human body will accompany the person's life. If the metabolism of the human body slows down and the accumulation of sugar (glucose, fructose, galactose, etc.) in the body is too much, it will be with the body Through non-enzymatic glycosylation reactions, advanced glycation end products (Advanced glycation end end products, AGEs) are finally generated. AGEs are a kind of protein, and its generation and accumulation are inevitable with age. The ...
