Problems solved by technology

[0010] However, at present, tea tree flower essence is mainly extracted through ultrasonic-assisted extraction, microwave-assisted extraction, solvent extraction, supercritical CO 2 Extraction, simultaneous distillation and extraction are used to prepare tea tree flower extracts, but there are few studies on the follow-up separation methods of tea tree flowers. Generally, tea tree flower extracts are prepared by conventional methods such as filtration and centrifugation, and further refined tea tree flower essence is still needed. Ability to improve the aroma, smoke and / or mouthfeel properties of, in particular, cigarettes

Abstract

The invention belongs to the field of spices and tobaccos, and relates to a segmented camellia sinensis flower exaction and a preparation method thereof, and application of the exaction in cigarettes. Particularly, the preparation method of the camellia sinensis flower exaction comprises the step of performing molecular distillation on the camellia sinensis flower exaction. The invention further relates to the camellia sinensis flower exaction prepared by the preparation method. The camellia sinensis flower exaction can remarkably improve smoking quality and sensory comfort of the cigarettes, and can improve characteristics of the fragrance, the smoke and / or taste of the cigarettes respectively.

Description

technical field [0001] The invention belongs to the fields of spices and tobacco, and relates to a segmented tea tree flower extract, a preparation method thereof and its application in cigarettes. Background technique [0002] Flavors and fragrances are widely used in tobacco, food, daily chemicals and other fields, and natural flavors are indispensable raw materials for blending flavors due to their complex composition, rich aroma, and long-lasting fragrance. [0003] Tea tree (Camellia sinensis) is a plant of the genus Camellia in the family Theaceae, and its cultivation has a history of thousands of years. Tea tree flowers are very rich in resources as a by-product of the tea production process. In recent years, more and more attention has been paid to the comprehensive utilization of tea tree flowers. [0004] Tea tree flowers are rich in protein, tea polyphenols, tea polysaccharides, tea saponin, flavonoids, amino acids, vitamins, trace elements, superoxide dismutase...
