Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of extraction and preparation of Phyllanthus emblica, and particularly relates to a preparation method of Phyllanthus emblica extract for improving the quality of heat-not-burn cigarettes. BACKGROUND

[0002] Phyllanthus emblica, also known as Amolak, Amba, Dianolive and Oil Phyllanthus, is a plant of Phyllanthus in Euphorbiaceae. Because the fruit is sour at first and sweet after a while, it is named Phyllanthus emblica. Phyllanthus emblica is listed in the list of dual-purpose plants of food and medicine in China. Phyllanthus emblica fruit can be eaten fresh or processed into food. In Sichuan, Guangdong and Yunnan of China, Phyllanthus emblica tea is drunk to effectively relieve indigestion. Phyllanthus emblica fruit is rich in 17 kinds of amino acids, vitamins, polyphenols, flavonoids and sugar components, and also contains many organic acid components such as gallic acid, mucilage acid, malic acid and chlorogenic acid. The main effects of organic acids on cigarettes are to increase the acidity of smoke, improve the concentration of smoke, make smoke mellow, increase the sweet and smooth feeling and improve comfort, and they play an important role in the functional components of tobacco flavor.

[0003] There are related patents about the development of Phyllanthus emblica extract as tobacco flavor materials. For example, CN201910320895.X discloses a method for enriching Phyllanthus emblica tannin fraction, and CN202010795966.4 discloses a Phyllanthus emblica targeted refined product and a preparation method. Both of them use macroporous adsorption resin to enrich tannin components in Phyllanthus emblica. However, since Phyllanthus emblica extract itself contains many macromolecular substances such as polysaccharides, starch and pectin, the use of macroporous adsorption resin for separation will easily produce flocculent substances, affecting the separation effect. Direct addition and application in cigarettes will produce burning odor and a certain degree of mouth astringency, resulting in poor sensory evaluation of cigarettes. Moreover, there are relatively few related patents about the use of Phyllanthus emblica extract in heat-not-burn cigarettes. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a preparation method of Phyllanthus emblica extract for improving the quality of heat-not-burn cigarettes, which can improve the purity of Phyllanthus emblica extract.
