Mildew-proof and aroma-increasing water immersion fermentation method for modulating tobacco leaves

Abstract

The invention relates to the technical field of tobacco leaf fermentation, in particular to a mildew-proof and aroma-increasing water immersion fermentation method for modulating tobacco leaves, which comprises the following steps of: screening tobacco leaves, separating tobacco leaf wastes from preferable tobacco leaves, putting the preferable tobacco leaves into a shed, shading and withering, pulling a plastic film, fully drying in the sun, yellowing, fixing color and taking off a shelf; cleaning and soaking the color-fixed dry tobacco leaves in water added with food mildew preventive DHA in proportion, taking out the tobacco leaves, preparing tobacco leaf waste into a tobacco extracting solution, spraying the tobacco extracting solution onto the tobacco leaves, spraying optimized bacillus on the tobacco leaves, and stacking the tobacco leaves on a plastic film on which the artemisia abrotanoides and perilla frutescens are paved in a layered manner with tobacco stems of the tobacco leaves facing outwards and the tobacco leaves facing inwards for fermentation. By the adoption of the method, after full soaking fermentation, the tobacco leaves do not mildew, green leaves are few, pesticide residues do not exist, components of the tobacco leaves are decomposed and converted through microorganisms, and a primary product of the tobacco which is better in color and luster, thicker in mellowness and better in taste is prepared.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf fermentation, in particular to a mildew-proof and perfume-increasing fermentation method for preparing dry tobacco. Background technique [0002] Compared with flue-cured tobacco, air-cured tobacco has unique tobacco leaf quality, which can meet the diverse needs of cigarette brands for raw materials. Traditional air-dried tobacco is prepared in the external environment, under natural conditions such as light and heat, to coordinate the water loss rate and color change of the tobacco leaves, so as to decompose and transform the chemical components in the tobacco leaves. [0003] There are many types of sun-dried tobacco in my country, and the modulation techniques vary according to the local climate. The curing process of sun-dried tobacco includes methods such as direct drying, direct drying, and combination of drying and drying. Each region adapts to local conditions, and the processing met...
