Abstract

The invention aims to provide a preparation method and application of an iris extract for fermented cigarette. The preparation method comprises the following steps: slicing and grinding the iris root,with the assistance of ultrasonic waves; adding a composite biological and performing biotransformation fermentation; performing microwave spray drying of the fermentation broth to obtain an iris fermentation product; putting the iris fermentation product into a microfiltration bag; performing soxhlet reflux extraction using an ethanol solution; and performing liquid-liquid extraction and purification using ethyl acetate, and microwave spray drying to obtain the iris extract for fermented cigarette. In the iris extract for fermented cigarette, few impurities are contained, abundant types of aroma are supplied, the flavonoid and other active substances have high purity, the aroma quality is improved, and the defects of obvious characteristic aroma and relatively great irrigation of the iris extract without biotransformation extraction are overcome; the process operation is simple, the process conditions are mild, and the filtrate is directly obtained without the time-consuming suctionfiltration; the temperature is kept relatively low during the process, and thus the aroma components and other active components in iris are maintained relatively well; when applied to traditional cigarette and novel cigarette products, the iris extract has the functions of improving the aroma quality, enriching the aroma, enhancing the aged cigarette flavor and improving the smoke and mouthfeel.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to a preparation method and application of fermented tobacco iris extract. Background technique [0002] Flavoring is a key link in the cigarette process, which can improve product style characteristics and improve the sensory quality of cigarettes. At present, tobacco flavors are mainly divided into natural flavors and chemically synthesized flavors that are directly extracted from tobacco or other plants by various separation methods. Natural tobacco flavors are popular due to their naturalness, but their preparation methods and processes still have defects such as low extraction rate, high production cost, low purity, more impurities, greater irritation, and characteristic aromas that cover tobacco aromas. [0003] Iris is a perennial herb distributed in central and southern China. Iris root is the rhizome of Iris tectorum Maxim., which is bitter, sweet, cold in natur...
