Problems solved by technology

[0002] As a kind of tobacco product, reconstituted tobacco leaves often need to add a certain amount of flavors and fragrances and tobacco extracts in the production process to improve the aroma characteristics of the product, cover up the miscellaneous gas and endow the product with a unique style, but the preparation, coating, drying, etc. During the storage and transportation of the process and later products, the fragrance substances are often destroyed, and a large amount of heat-sensitive substances or volatile substances will be lost.

preparation example Construction

[0020] A preparation method and application of microcapsules based on gelatinization of tobacco protein and tobacco polysaccharide, comprising the following steps:

[0021] Step 1: Preparation of tobacco protein-enriched phase: put tobacco leaf raw materials into an extraction tank whose extraction solvent is water, add protein co-solvent, control a certain temperature, stir and extract for a period of time, and perform solid-liquid separation to obtain crude tobacco protein Extraction. Tobacco protein is adsorbed by macroporous adsorption resin, eluted by ethanol aqueous solution, and concentrated into a certain concentration of tobacco protein rich phase.

[0022] Step 2: Preparation of Tobacco Polysaccharide-enriched Phase: Put the tobacco stem raw material into an extraction tank with water as the extraction solvent, control a certain temperature, stir and extract for a period of time, and perform solid-liquid separation to obtain crude tobacco polysaccharide extract. A c...

Embodiment 1

[0026] Step 1: Preparation of tobacco protein-enriched phase: put Burley tobacco fragments into an extraction tank whose extraction solvent is water, add 3 parts of urea, 8 parts of sodium chloride, 38 parts of ammonium sulfate, and 51 parts of sodium sulfate. The numbers are parts by weight. Stirring at a temperature of 55° C. and a stirring speed of 100 r / min for 1.5 h to obtain crude tobacco protein extract. Tobacco protein is adsorbed by D3520 macroporous adsorption resin, eluted with 85% ethanol aqueous solution, and concentrated into a certain concentration of tobacco protein enriched phase.

[0027] Step 2: Preparation of the tobacco polysaccharide-rich phase: put the tobacco stem raw material into an extraction tank whose extraction solvent is water, stir at a temperature of 60°C and a stirring speed of 100r / min for 1.5h, and perform solid-liquid separation to obtain tobacco Crude polysaccharide extract. Adding 90% ethanol aqueous solution to the crude tobacco polysa...

[0031] Step 1: Preparation of tobacco protein-enriched phase: Burley tobacco fragments are put into an extraction tank in which the extraction solvent is water, and the parts by weight are added to form: 5 parts of urea, 7 parts of sodium chloride, 45 parts of ammonium sulfate, 43 parts of Parts Sodium Sulfate. Stirring at a temperature of 50° C. and a stirring speed of 100 r / min for 1.5 h to obtain crude tobacco protein extract. Tobacco protein is adsorbed by D3520 macroporous adsorption resin, eluted with 85% ethanol aqueous solution, and concentrated into a certain concentration of tobacco protein enriched phase.

[0032] Step 2: Preparation of the tobacco polysaccharide-rich phase: put the tobacco stem raw material into an extraction tank whose extraction solvent is water, stir at a temperature of 65°C and a stirring speed of 100r / min for 1.5h, and perform solid-liquid separation to obtain tobacco Crude polysaccharide extract. Adding 95% ethanol aqueous solution to the t...

Abstract

The invention provides a microcapsule preparation method based on tobacco protein and tobacco polysaccharide gelatinization as well as application. A tobacco protein and tobacco polysaccharide microcapsule is prepared by taking natural proteins and polysaccharides in tobacco as an embedding wall material of tobacco extract. The microcapsule is applied to reconstituted tobacco by means of a paper-making process, so that the sensory quality of the reconstituted tobacco can be improved, and the problem that loss of volatile components in production and storage processes is severe is solved.

Description

technical field [0001] The invention relates to a preparation method and application of microcapsules based on tobacco protein and tobacco polysaccharide gelation, and belongs to the technical field of tobacco manufacturing. Background technique [0002] As a kind of tobacco product, reconstituted tobacco leaves often need to add a certain amount of flavors and fragrances and tobacco extracts in the production process to improve the aroma characteristics of the product, cover up the miscellaneous gas and endow the product with a unique style, but the preparation, coating, drying, etc. During the storage and transportation of the process and later products, the fragrance substances are often destroyed, and a large amount of heat-sensitive substances or volatile substances will be lost. In recent years, microcapsule encapsulation has been used to control the release of flavors and fragrances during the process. Gelatin, gum arabic and other substances are generally used as wal...
