Abstract

The invention discloses a preparation method for litchi pericarp extract and application of the same in the production of a cigarette. The preparation method comprises the following steps of: refluxing and extracting litchi pericarp powder by using petroleum ether; collecting refluxed and extracted solid residue; and determining proper enzymolytic conditions and subjecting primarily extracted residue of litchi pericarp to enzymolysis and further purification. The prepared litchi pericarp extract can be well matched with scent and taste of the cigarette after being added into the cigarette, and is beneficial to the increase of the scent, improvement of quality, reduction of pungent smell, removal of foreign matters and reduction of release amount of harmful components of the cigarette, and has a certain promotion function on the improvement of the comprehensive quality of the cigarette.

Description

technical field [0001] The invention belongs to the technical field of spices for tobacco, and in particular relates to a preparation method of litchi peel extract and its application in cigarette production. Background technique [0002] Litchi (Litchi chinensis Sonn.) is the fruit of Sapindaceae evergreen plants, known as "Lingnan Fruit King". In 2010, my country's litchi output was about 1.7 million tons, accounting for 63% of the world's total litchi output. The weight of litchi peel accounts for about 16% of the total weight of the fruit. It is rich in flavonoids and water-soluble polysaccharides and other physiologically active substances, and has high medicinal value. [0003] At present, litchi peel is mainly used to extract physiologically active substances. For example, Chinese invention patent (CN200510093663.3) discloses a method for extracting litchi polyphenols from litchi peel. Chinese invention patent (CN200610032402.5) discloses a method for extracting tan...
