Preparation method of clove extract for base oil of flavor capsule

Abstract

The present invention provides a preparation method of a clove extract for base oil of a flavor capsule. The preparation method of the clove extract includes: soaking clove buds in 30-95% ethanol solution; heating the solution to reflux at a temperature of 30 to 60 DEG C, and then cooling and filtering the solution; collecting the filtrate and concentrating the filtrate under vacuum for removing the extraction solvent to obtain a clove extractum; adding octyl and decyl glycerate and Span 60, and treating the mixture by ultrasound at a frequency of 20 to 40 kHz under 30 to 60 DEG C for 0.5 to 2hours; and performing filtration to remove impurities and insolubles, and collecting the filtrate so as to obtain the clove extract. The invention provides a simple extraction method, and the obtained clove extract can be directly added into the base oil of the flavor capsule and used to prepare flavor capsules for cigarettes, and the forming stability of the clove extract is good. The flavor capsule can be added into filter tips to make cigarettes. A smoke panel test shows that the aroma of clove is strong and the aroma is rich and pure.

Description

technical field [0001] The invention relates to the field of flavors and fragrances for tobacco, in particular to a preparation method of clove extract used for popcorn base oil. Background technique [0002] The traditional method of adding flavors may produce new harmful substances while losing aroma substances due to the participation of flavors and fragrances in combustion. Popping beads is a special process for flavoring cigarette auxiliary materials and a major innovation in the tobacco industry. The method of popping beads and flavoring improves the safety of cigarette products and greatly enriches the types of flavoring materials. Today, the research and development of explosive pearl cigarettes has become an innovative means for major tobacco companies to innovate categories, improve category structure, and meet diversified market needs. [0003] The essence used in the base oil of the popcorn is basically a synthetic flavor, which plays an important role in enhanc...

Problems solved by technology

There are some small molecular substances with special aroma components in synthetic flavors. Although these substances can enhance the aroma, due to the relatively strong penetrating power of these small molecular substances, it will cause instability such as shaking, eccentricity, and excessive gaps during the online molding process of popping beads. state, thus affecting the bead forming

[0004] At present, the clove extract used for popping pearls is generally extracted by direct heating with oily solvents. This method not only makes it difficult to reveal the aroma of the raw materials, but also tends to produce peculiar smells after the solvent is heated, and the aroma of cloves is also easy to be distorted after being matured in oily solvents.
