This invention discloses a tobacco extract, its preparation method, and its application, belonging to the field of tobacco flavoring technology. The preparation method includes: mixing water, propylene glycol, triethylene glycol, and glycerol into a quaternary composite solution, adding tobacco raw materials, glycine, glutamic acid, and alanine, and mixing thoroughly; obtaining a centrifuged clear liquid after extraction, which is then sequentially separated through a ceramic membrane, an ultrafiltration membrane, and a nanofiltration membrane; adding an organic acid to the membrane separation product, which is the tobacco extract. It can be used as a flavor enhancer in traditional cigarettes, significantly improving the richness, aroma, and satisfaction of the smoke; it can also be used directly as a base liquid for atomizing new tobacco products, without the need for adding large amounts of additional atomizing agents, producing sufficient and sustained smoke, with prominent tobacco aroma characteristics, a clean and comfortable aftertaste, and no irritation or sweetness.

The application belongs to the technical field of food processing, and particularly relates to high-purity resistant starch concentrate and a preparation method thereof. Low-purity resistant starch ultrafine powder with a dry basis resistant starch content of 30% to 35% is used as raw material, and after being slurried, the raw material is subjected to double-enzyme hydrolysis of alpha-amylase and saccharifying enzyme to specifically remove digestible starch, dextrin and oligosaccharide in the raw material; then, the enzyme is inactivated, centrifugal separation and multiple water rinsing purification are performed, and high-purity resistant starch wet material with a dry basis resistant starch content of greater than or equal to 90% is obtained; after the wet material is proportionally mixed with water, high-pressure microjet homogenization treatment is performed to fully hydrate and disperse the particles, and finally, stable concentrate with a concentration of greater than or equal to 50% w / v is obtained. The purity of resistant starch is greatly improved, and the efficacy is significantly enhanced. The application uses low-cost low-purity resistant starch with a purity of about 30% as raw material, removes digestible starch, dextrin and oligosaccharide through double-enzyme hydrolysis with precise specificity, and combines physical rinsing and purification, so that the dry basis purity of resistant starch can be stably improved to more than 90%, and the physiological activity per unit weight is stronger.
