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 tobacco protein and tobacco polysaccharide gelation, including the following steps:

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

[0022] Step 2: Preparation of the tobacco polysaccharide-rich phase: Put the tobacco stem 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 a crude tobacco polysaccharide extract. A certain c...

Embodiment 1

[0026] Step 1: Preparation of the tobacco protein-enriched phase: Put the burley tobacco fragments into the extraction tank with the extraction solvent of water, add 3 parts urea, 8 parts sodium chloride, 38 parts ammonium sulfate, 51 parts sodium sulfate, The numbers are parts by weight. At a temperature of 55° C. and a stirring speed of 100 r / min for 1.5 hours, a crude tobacco protein extract was obtained. D3520 macroporous adsorption resin is used to adsorb tobacco protein, and 85% ethanol aqueous solution is used for elution, and it is concentrated into a certain concentration of tobacco protein enriched phase.

[0027] Step 2: Preparation of the tobacco polysaccharide enriched phase: Put the tobacco stem material into the extraction tank with the extraction solvent of water, and stir for 1.5h at a temperature of 60°C and a stirring speed of 100r / min for solid-liquid separation to obtain tobacco Crude polysaccharide extract. A 90% ethanol aqueous solution is added to the cr...

[0031] Step 1: Preparation of tobacco protein-enriched phase: Put the burley tobacco fragments into the extraction tank with water as the extraction solvent, and add the parts by weight to become: 5 parts urea, 7 parts sodium chloride, 45 parts ammonium sulfate, 43 Parts of sodium sulfate. At a temperature of 50°C and a stirring speed of 100r / min for 1.5h, a crude tobacco protein extract was obtained. D3520 macroporous adsorption resin is used to adsorb tobacco protein, and 85% ethanol aqueous solution is used for elution, and it is concentrated into a certain concentration of tobacco protein enriched phase.

[0032] Step 2: Preparation of the tobacco polysaccharide enriched phase: Put the tobacco stem raw materials into the extraction tank with the extraction solvent of water, and stir for 1.5h at a temperature of 65°C and a stirring speed of 100r / min for solid-liquid separation to obtain tobacco Crude polysaccharide extract. A 95% ethanol aqueous solution was added to the cru...

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 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 impurities and give the product a unique style, but during the production process, it is formulated, coated, dried, etc. During the process and the storage and transportation of later products, aroma substances are often destroyed, and heat-sensitive substances or volatile substances will suffer a lot of loss. In recent years, microcapsule packaging has been used to control the release of flavors and fragrances during the process. Microcapsule packaging generally uses materials such as gelatin and gum arabic ...
