For smokeless tobacco products containing the above-mentioned microcapsules or micro-smoke tablets, at the initial stage of the consumption process, the content of microcapsules or micro-smoke tablets in the product is still relatively large, and the contact area with the mouth or saliva is also relatively large. Therefore, the initial

Abstract

The invention belongs to the field of tobacco, and discloses a tobacco extractive particle and a preparation method thereof. The tobacco extractive particle comprises at least two substrate layers with different tobacco extractive contents, wherein the substrate layers are wrapped layer by layer, the surfaces of the substrate layers are wrapped by coating layers, and the substrate layers internally contain excipients; and the tobacco extractive contents of the substrate layers from, the inside to the outside, of the tobacco extractive particle are gradually decreased. Tobacco extractives employ water and ethanol as extractants, and through low-temperature ultrasonic extraction by use of two-step method, the extraction amounts of effective components are ensured. The preparation method of the tobacco extractive particle comprises an extruding-rolling granulation method and a fluidized bed granulation method. The prepared particle has a multilayer structure, is uniform in structure and guarantees the mouthfeel and local flavor of a novel tobacco product with the tobacco extractive particle added thereto.

Description

technical field [0001] The invention belongs to the field of tobacco, and more specifically relates to a tobacco extract particle and a preparation method thereof. Background technique [0002] Tobacco extract has been widely used in the research or production of smokeless tobacco products as a very important way. In traditional methods, tobacco extracts are generally directly added to traditional tobacco and smokeless tobacco products in the form of paste or powder. Because traditional tobacco products participate in the burning process of cigarettes, the way of direct addition makes them have basically the same or better effect than the basic raw material tobacco leaves. However, in smokeless tobacco products, due to changes in consumers’ intake of nicotine and other substances in the product, if tobacco extracts are directly added to the product, nicotine and other substances will be released quickly and continuously in the consumer’s mouth. The time is short and the t...
