Preparation method of fruit concentrate Maillard reaction product, and application of product in tobacco perfuming

The invention relates to a preparation method of a fruit concentrate Maillard reaction product, and an application of the product in tobacco perfuming. The preparation method comprises the following steps: mixing a fruit concentrate or the fruit concentrate containing reducing monosaccharide with amino acids and a reaction solvent, using an aqueous solution of sodium hydroxide to adjust the pH value of a reaction system to 6-9, heating to 80-100DEG C within 20-90min, continuously reacting for 0.5-1.5h, and cooling to obtain the corresponding reaction product. The Maillard reaction product generated after reacting the fruit concentrate with the amino acids is rich in the natural perfume of fruits, can be naturally coordinates with the original perfume of tobacco, and is safe and reliable. The above reactive perfume prepared in the invention is used to process cut tobacco under certain conditions, and is added to tobacco according to different proportions, so the smoking quality of the the prepared cut tobacco is substantially improved. The fruit concentrate Maillard reaction product can improve the fullness and the softness of the smoke of cigarette, improves the smoking smell comfortableness, and highlights the delicate perfume style of the cigarette.

Method for manufacturing reconstituted tobacco suited to flue-cured tobacco flavor from sun-cured tobacco

The invention provides a method for manufacturing reconstituted tobacco suited to flue-cured tobacco flavor from sun-cured tobacco. The method for manufacturing reconstituted tobacco suited to flue-cured tobacco flavor from sun-cured tobacco comprises the steps as follows: a water extracting solution of a sun-cured tobacco material and a water extracting solution of flue-cured tobacco stems are mixed and concentrated to form a coating solution, and slices are prepared from water extraction filter residues of the sun-cured tobacco material and water extraction filter residues of the flue-cured tobacco stems through mixing with a papermaking method, and are then coated with the coating solution; a special complex enzyme preparation and aids are added during water extraction, concentration and pulping respectively. Excessive macromolecular substances such as protein, pectin, starch and the like in the sun-cured tobacco material are degraded through a special enzyme group, and a large number of small-molecule substances and precursors of flavoring substances are produced; meanwhile, the extraction efficiency is improved, and offensive odor and irritation produced by the reconstituted tobacco after combustion are reduced; various aroma producing and aroma increasing reactions are performed in the concentration process, and accordingly, the aroma quality of the reconstituted tobacco is improved, and the satisfaction and the coordination of smoke are increased.
