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

The invention relates to a preparation method of a modified fruit concentrate Maillard reaction product, and an application of the product in tobacco perfuming. The preparation method comprises the following steps: mixing a modified fruit concentrate containing a modifier with amino acids and a reaction solvent, adjusting the pH value of a reaction system by an aqueous solution of sodium hydroxide to 6-11, heating to 80-130DEG C within 20-50min, continuously reacting for 0.5-3.5h, and cooling to obtain the corresponding reaction product. The modifier is a tobacco extract product and plant extract paste. The reaction product is rich in the natural perfume of fruits and natural plants, and the natural perfume is naturally coordinated with the original perfume of tobacco to form a safe and reliable novel cigarette perfume. The reactive perfume prepared in the invention is added to tobacco according to different proportions, and the tobacco is processed under certain conditions, so the smoking quality of prepared cut tobacco is obviously improved. The modified fruit concentrate Maillard reaction product enables the perfume of cigarette to be rich, mellow and full, and substantially concentrates the perfume of cigarette.
