Description

Method for preparing cigar flavor from cigar wastes, flavor and application

Technical Field

The invention relates to the technical field of essence for cigars, in particular to a method for preparing spice for cigars from cigar wastes and application of the spice.

Background

Cigars are a special type of tobacco product, the traditional concept of which is a smoking cigarette that is entirely rolled up from tobacco leaves. With the improvement of economic level and the improvement of living standard of people, the demand of cigars in China is continuously increased. But the shortage of high-quality cigar raw materials and the limited access to high-quality cigar raw materials such as cuba, dominica and the like in China limit the development space of domestic cigar products and industries. A great deal of crushed leaves and tobacco powder are generated in the processes of threshing and cigar rolling, namely, the crushed leaves and the tobacco powder are waste and are generally discarded and cannot be reasonably utilized. The cigar broken leaves and the tobacco powder still contain the components of high-quality raw materials, and have important effect on improving the cigar quality. Therefore, the invention aims to prepare the waste cigar tobacco leaves into the cigar flavor, improve the comprehensive utilization rate of high-quality raw materials, extract the unique flavor components of the cigar tobacco leaves and develop a series of flavors with cigar flavor notes for compensating the problems of insufficient flavor of the domestic cigar tobacco leaves and the like.

Disclosure of Invention

The invention aims to solve the problems and provides a method for preparing a cigar flavor from cigar wastes, which can improve the utilization rate of high-quality cigar raw materials, can be used for flavoring cigar products and can improve the cigar quality.

The purpose of the invention is realized by the following technical scheme:

the method for preparing the cigar flavor from the cigar wastes comprises the following steps:

the cigar waste is subjected to a solvent extraction method to obtain a cigar extract, the cigar extract is subjected to reduced pressure concentration to obtain a cigar tobacco extract, the extract is subjected to alcohol precipitation and freezing dewaxing, then filtration is carried out, and the filtrate is collected to obtain the cigar tobacco extract, namely the cigar tobacco flavor.

In a further scheme, the cigar waste comprises cigar broken leaves, tobacco powder and tobacco stems.

In a further scheme, the solvent extraction method uses 30-95% ethanol/water solution as an extraction solvent.

The further scheme is that the material-liquid ratio of the solvent extraction method is 1: 5-1: 15, and the solvent extraction method is used for condensing reflux extraction at room temperature to 90 ℃.

The further scheme is that ethanol precipitation is to add ethanol/water solution with the ethanol volume content of more than or equal to 95% into the extract, the dosage of the ethanol/water solution is 5-15 times of the mass of the extract, the temperature of freezing and dewaxing is-20 ℃, and freezing is carried out for 24-48 hours.

The further scheme is that the reduced pressure concentration conditions are that the water bath temperature is 40-50 ℃, and the vacuum degree is 0.8-1.0 MPa.

The cigar flavor is prepared by the method.

The cigar flavor prepared by the invention can be applied to manual cigars, machine-made cigars and cigar type cigarettes, and is used according to 0.10-5.0% of the weight of tobacco leaves.

The solvent extraction method can extract volatile and nonvolatile components in cigar waste, wherein the volatile and nonvolatile components also comprise macromolecular components such as cellulose, hemicellulose, pectin and protein, and the macromolecular components are difficult to dissolve in ethanol solution, especially high-concentration ethanol solution, and the macromolecular components are removed by adopting an alcohol precipitation method. The reduced pressure concentration can remove the organic solvent, prepare the extract, and facilitate the subsequent alcohol precipitation and freezing wax removal. The surface of the plant leaf has a waxy structure, and the plant leaf is easy to dissolve and extract under the conditions of organic solvent and heating extraction. The scorching sense generated during burning of the wax component influences sensory evaluation, and the wax can be effectively separated out by low-temperature freezing and can be removed by filtering under the low-temperature condition.

The ethanol used in the invention refers to a solution prepared by ethanol and water according to a volume ratio under the condition of indicating the content of the ethanol, for example, 70% ethanol refers to a solution prepared by ethanol water according to a volume ratio of 70%: 30% of ethanol and water.

The invention has the beneficial effects that:

1. the method of the invention can improve the utilization rate of the high-quality cigar raw material and reduce the cost of the raw material.

2. The spice is sprayed on the domestic cigar tobacco leaves, and the cigar tobacco leaves are rolled into cigar finished products, and through sensory evaluation, the fragrance and the nut fragrance of the sun-cured tobacco can be increased, the sweetness is increased, the fragrance is enriched, the layering sense is improved, and the smoke is fine and mellow.

3. The cigar flavor prepared by the invention can be used for the product development of cigarettes, cigar tobacco products and novel tobacco products.
