Abstract

The invention discloses a preparation method of sweet potato water extract, which comprises the steps of washing and peeling, crushing and beating, decompression filtering, starch removal and decompression concentration. The starch is removed by centrifugation and enzyme treatment, and it can be concentrated to a certain concentration under vacuum conditions; the sweet potato water extract prepared by the present invention is evenly sprayed on the shredded tobacco in the cigarette feeding process, highlighting the "roasted sweet" aroma of cigarettes, and then The smoking quality and sensory comfort are improved, the cigarette aroma is significantly improved, the aftertaste is improved, and the irritation and miscellaneous gas are also greatly reduced. The product of the invention has low cost, simple process and high safety, and is worthy of popularization and application in the whole industry.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction and application, and in particular relates to a water extract of sweet potato, its preparation method and its application in cigarettes. Background technique [0002] With the rapid development of my country's economy, consumers have higher and higher requirements for the inherent quality of cigarettes. However, compared with well-known foreign brands, domestic cigarette products have certain gaps in smoking quality and sensory comfort, such as weak aroma, strong dryness, insufficient sweetness, and poor comfort. Therefore, it is an inevitable trend in the development of domestic cigarettes to increase the aroma of cigarettes, reduce dryness, and improve comfort. [0003] Sweet potato is rich in nutrition and balanced, and its nutritional value is not lower than that of rice and noodles. According to research reports at home and abroad, sweet potato V C , V E , V B1 and V ...
