Method for preparing slices reconstituted from tea, and application in tobacco product

Abstract

A preparation method of tea reconstituted sheet and its application in tobacco products. The preparation method uses tea or the mixture of tea and tobacco as raw material, and after water extraction, catalytic degradation, mixing and pulping, it is copied into a base sheet, and then concentrated The final tea extract is applied to the substrate, and the substrate is rolled, cut and dried to obtain a tea reconstituted sheet. It can be used alone or mixed with shredded tobacco to make tobacco products, which can completely or partially replace tobacco leaves, change the style characteristics of tobacco products, make the smoke delicate, soft and smooth, prolong the fragrance, and reduce the sharp and stinging throat , Rough, pungent and other uncomfortable feelings, significantly improving the consistency and stability of the aroma of burning smoke. At the same time, it can significantly reduce the contents of tar, nicotine and carbon monoxide released from cigarette smoke.

Description

technical field

[0001] The invention relates to a preparation method of tea reconstituted sheet and its application in tobacco products. Background technique

[0002] Reconstituted tobacco leaves (also known as tobacco flakes) are made from tobacco leaves, tobacco stems, and waste tobacco (broken tobacco leaves, tobacco powder) through solvent extraction, separation, recombination, rolling (or papermaking after pulping) and other technologies. manufactured tobacco products. At present, the production process of reconstituted tobacco leaves at home and abroad mainly adopts improved papermaking method, rolling method or thick pulp method. Among them, the papermaking reconstituted tobacco has the advantages of low density, high filling value, good flexibility and processing resistance, high filament rate, fast burning speed, low tar release, and strong product plasticity. Its physical and chemical indicators can be manually adjusted and other good formula characteristics, and...

Embodiment 1

[0014] Example 1: Preparation method and application of tea reconstituted flakes with 70% spreading rate

[0015] After the oolong tea (such as: Tieguanyin) tea stems are pretreated, water extraction is carried out with a three-stage single-pot batch extraction method, wherein the first-stage extraction temperature is 50°C, and the extraction is 5 minutes; the second-stage extraction temperature is 65°C, and the extraction is 10 minutes. Minutes; the temperature of the three-stage extraction is 80°C, and the extraction takes 20 minutes, and the ratio of solid to liquid during the above three-stage extraction is 1:9. Separation of tea stalk residue and tea extract, concentrated tea extract for later use, tea stalk residue mixed with Tieguanyin, Dahongpao and other tea powder and leaves, adding pectinase, α-amylase, cellulase, etc. to catalyze Enzyme, adding stone alkali (mainly containing inorganic substances such as sodium carbonate and potassium carbonate), heating again, imp...

Embodiment 2

[0018] Example 2: Preparation method and application of tea reconstituted flakes with 120% spreading rate

[0019] After the green tea (such as: Maojian) tea stems are pretreated, water extraction is carried out with a three-stage single-pot batch extraction method, wherein the first-stage extraction temperature is 55°C, and the extraction is 8 minutes; the second-stage extraction temperature is 70°C, and the extraction is 15 minutes. Minutes; the temperature of the three-stage extraction is 85°C, the extraction is 20 minutes, and the ratio of solid to liquid during the above three-stage extraction is 1:10. Separate the tea stem residue and tea extract, concentrate the tea extract for later use, mix the tea stem residue with Tieguanyin, Maojian and other tea powder and broken leaves, add pectinase, α-amylase, cellulase, etc. to catalyze Enzyme, adding stone alkali (mainly containing inorganic substances such as sodium carbonate and potassium carbonate), heating again, impregna...
