Abstract

The invention provides a method for preparing an apricot extract for cigarette by immobilized saccharomycetes. The method comprises the following steps: (1) juicing fresh apricot; (2) preparing a saccharomycetes bacterial suspension; (3) immobilizing saccharomycetes with sodium alginate-CaCl2; (4) performing fermenting reaction on the immobilized saccharomycetes and the apricot juice; (5) filtering fermentation liquor, thereby acquiring clear fermentation liquor, and then performing alcohol precipitation and vacuum concentration, thereby acquiring the apricot extract. According to the invention, the apricot is taken as a raw material and the immobilized saccharomycetes are utilized to ferment the apricot juice, so that the high-quality apricot extract for cigarette can be acquired. The extract in cigarette has the functions of enriching cigarette flavor, inducing cigarette fragrance, increasing fruity sweet and fragrance, enhancing smoke saliva-generating feel, softening and fining smoke, relieving throat irritation, and the like.

Description

technical field [0001] The invention relates to the field of tobacco additives, in particular to a method for preparing tobacco apricot extract by using immobilized yeast. Background technique [0002] Flavoring is a key link in the cigarette process, and it is one of the effective means to improve the determinant of product style and improve the quality of cigarette aroma. At present, flavors and fragrances for tobacco are mainly prepared through extraction and chemical synthesis of natural animals and plants. Due to limited natural plant resources and harsh conditions for chemical synthesis. With the development of biotechnology, in recent years, the use of microbial fermentation to prepare tobacco flavor raw materials provides an economical and efficient way for the production of tobacco flavor raw materials, and develops some new types of tobacco flavor raw materials that cannot be produced by traditional methods. [0003] Microbial immobilization technology is a biote...
