Embodiment 1

[0027] A preparation method for immobilized fermented extract of Maryland tobacco leaves, comprising the steps of:

[0028] (1) Pre-treatment of raw materials: Maryland tobacco leaves are pulverized into 40-mesh coarse powder through a pulverizer;

[0029] (2) Activation of microbial strains: add the active solid freeze-dried bacterial powder (food grade, activity 10u / mg) of Saccharomycopsis fibuligera and Enterobacter moriVL4-3 to 10 times the mass In the sterilized 5% glucose solution, place it in a 38°C water bath for activation for 30 minutes to obtain a microbial strain activation solution;

[0030] (3) Preparation of immobilized carrier: wash and dry the immobilized carrier (the tobacco rod of Maryland tobacco) and cut it into small pieces about 1 cm long with scissors, and dry it after autoclaving;

[0031] (4) Immobilization treatment of microbial strains: Weigh the sterilized and dried Maryland tobacco stem fragments in the above step 3) into a 20L barrel, add a cert...

Embodiment 2

[0037] A preparation method for immobilized fermented extract of Maryland tobacco leaves, comprising the steps of:

[0038] (1) Pre-treatment of raw materials: Maryland tobacco leaves are pulverized into 60-mesh coarse powder through a pulverizer;

[0039] (2) Activation of microbial strains: add the active solid freeze-dried bacterial powder (food grade, activity 15u / mg) of Saccharomycopsis fibuligera and Enterobacter moriVL4-3 to 15 times the mass In the sterilized 12% glucose solution, place it in a 45°C water bath for activation for 45 minutes to obtain a microbial strain activation solution;

[0040] (3) Preparation of immobilized carrier: wash and dry the immobilized carrier (the tobacco rod of Maryland tobacco) and cut it into small pieces about 1 cm long with scissors, and dry it after autoclaving;

[0041] (4) Immobilization treatment of microbial strains: Weigh the sterilized and dried Maryland tobacco rod fragments in the above step 3) into a 20L barrel, add a cert...

Embodiment 3

[0047] A preparation method for immobilized fermented extract of Maryland tobacco leaves, comprising the steps of:

[0048] (1) Pre-treatment of raw materials: Maryland tobacco leaves are pulverized to 100 mesh powder by a pulverizer;

[0049] (2) Activation of microbial strains: add the active solid freeze-dried bacterial powder (food grade, activity 20u / mg) of Saccharomycopsis fibuligera and Enterobacter moriVL4-3 to 20 times the mass In the sterilized 20% glucose solution, place it in a 50°C water bath for activation for 60 minutes to obtain a microbial strain activation solution;

[0050] (3) Preparation of immobilized carrier: wash and dry the immobilized carrier (the tobacco rod of Maryland tobacco) and cut it into small pieces about 1 cm long with scissors, and dry it after autoclaving;

[0051] (4) Immobilization treatment of microbial strains: Weigh the sterilized and dried Maryland tobacco rod fragments in the above step 3) into a 20L barrel, add a certain amount (t...

Abstract

The present invention provides a preparation method and application of Maryland tobacco leaves fermented extracts. After the Maryland tobacco leaves are crushed, Maryland tobacco rods are used to immobilize and adsorb microbial strains, and the Maryland tobacco powder is incubated, hydrolyzed and fermented, combined with continuous countercurrent ultrasonic Extraction and preparation of Maryland tobacco leaf extract, the extract has strong natural tobacco aroma, reduced irritation, simple purification and separation steps, mild process conditions, improved extraction rate and production efficiency; adding ingredients to traditional cigarettes and new heat-not-burn cigarettes For incense application, it has natural tobacco aroma, full of strength, strong sense of hair penetration, with fruity and milky sweet aroma, which is in harmony with cigarette smoke and has the same style.

Description

technical field [0001] The invention relates to the field of tobacco additives, in particular to a preparation method and application of a Maryland tobacco leaf fermented extract. 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. The production of low-tar cigarettes needs more flavorings to make up for the lack of flavor. The purpose of tobacco product flavoring is to cover up the irritation and miscellaneous gas of natural tobacco, and to enhance or improve its fragrance. Many aroma substances can be identified from tobacco and smoke. The synthesis and application of these spices with the aroma of tobacco itself are being paid more and more attention. Because of its naturalness, safety and natural compound aroma, natural flavors are more catering to consumers' health needs. Among them, tobacco extracts are m...
