Description

Preparation method of Pu'er tea extract and its application in cigarettes

technical field

The invention relates to a preparation method of Pu'er tea extract and its application in cigarettes. the

Background technique

The tea polyphenols, alkaloids, free amino acids, vitamins, saponins, tea pigments and tea polysaccharides in Puer tea not only have strong antioxidant properties, but also can reduce harmful substances in smoke, and The polyphenols, amino acids and polysaccharides in it can also improve the taste of smoke, and play the role of promoting body fluid and moisturizing. the

The content of tea polyphenols in Pu'er raw tea is 25-28%, which has the sensory characteristics of promoting body fluid and sweetness, strong antioxidant activity and the ability to scavenge free radicals; tea polysaccharide is a kind of protein in tea Acidic polysaccharides or acidic proteoglycans. Tea polysaccharide has many biological functions such as lowering blood sugar, lowering blood fat, enhancing immunity, preventing radiation and anticoagulation, etc. The water-soluble sugar is the main component of the sweetness of tea soup, and it can relieve the bitter and astringent substance tea polyphenols in tea soup. 1. The stimulating effect of caffeine. The higher the sugar content in this part, the more mellow the taste of the tea; the alkaloids in the tea have the pharmacological functions of stimulating the human central nervous system, refreshing the mind, strengthening the heart and diuresis, and detoxification. Appropriate intake have a positive effect on the human body. Adding tea alkaloids to cigarettes can also achieve a refreshing effect when smoking, and alleviate the toxic effect of nicotine (nicotine) on the human body. Amino acids in tea are closely related to the taste and aroma of tea soup, especially the role of theanine, which is an important component of tea aroma and quality, and significantly affects the freshness of tea. Combining many biochemical components in tea leaves with cigarettes, adding them to the filter stick can improve the aroma and taste when smoking, and increase the sweet, mellow, moist and fragrant taste of cigarettes. the

Tea extract is a pure natural cigarette additive. At present, many reports use different extraction methods to make tea aroma substances into extracts to develop cigarette additives, and then make up for cigarette aroma, so as to increase the aroma and quality of cigarette smoke. Taste quality is improved. The various functional ingredients contained in the tea leaves make the tea extracts antibacterial and anti-inflammatory, heat-clearing and detoxifying, recovering sweetness and promoting body fluids, preventing caries and moths, anti-allergic substances and removing tobacco poison, etc. It can be used in cigarettes to play a role Breaks down and relieves the effects of harmful substances such as nicotine and tar. These provide a strong theoretical basis and development prospects for the development of tea tobacco. the
