Burley tobacco extract for heat-not-burn cigarettes and preparation method thereof

Abstract

The invention provides a burley tobacco extract applied to a heated-non-combustible cigarette and an application of the burley tobacco extract. With a composite biological material of burley tobacco stems and bagasse as an immobilized carrier, biological preparations, including a microbial aroma-producing strain and enzyme, are adsorbed; burley tobacco powder is incubated, hydrolyzed and fermented; and in combination with a continuous counter-current ultrasonic solvent extracting technology, the burley tobacco extract is prepared, and the burley tobacco extract can be combined with propylene glycol; intrinsic intense fragrance of natural tobacco is reserved; characteristic smell of burley tobacco is relieved and irritation is reduced; the burley tobacco has natural composite fragrance of fresh fruity aroma, smell of caramel, smell of being roasted and the like; the preparation method of gentle in process conditions, high in extracting rate and high in production efficiency; the burleytobacco extract is applied to a novel heated-non-combustible cigarette material; the burley tobacco extract is coordinate with cigarette fragrance and uniform in style, and the burley tobacco extractcan increase smoke concentration, enhance feeling of being satisfied and enrich cigarette aroma; and irritant smell of burley tobacco is obviously reduced, and taste is improved.

Description

technical field [0001] The invention relates to the field of smokeless cigarettes, in particular to a Burley tobacco extract used for heat-not-burn cigarettes and a preparation method thereof. Background technique [0002] Tobacco additives are additives to improve the physical and chemical properties of tobacco, including flavor essences, humectants, combustion enhancers, anti-mold agents and adsorbents. Compared with traditional combustion cigarettes, heat-not-burn cigarettes generally have a heating temperature below 500°C, usually 300°C, and have different effects on the aroma substances in cigarettes and the mechanism of producing aroma, which is often different from the sensory effect of cigarette smoking. It is larger and needs to be added with flavoring to make up for the lack of smoke. Due to its naturalness, safety and natural compound aroma, natural flavors are more catering to consumers' health needs, but they still have low extraction efficiency, many solvent r...
