Macroporous and microporous hybrid starch granule and preparation method and application thereof

Abstract

The invention discloses a macroporous and microporous hybrid starch granule and a preparation method and an application thereof; wherein, the method comprises the following steps: mixing the macroporous starch with pore diameter ranging from 0.5umm to 1.5umm with microporous starch with pore diameter ranging from 6A degree to 6.5 A degree according to the weight proportion of 0.5-4;1; then wetting, microwave drying, crashing and sifting are carried out on the mixture, thus obtaining the hybrid starch granule; the additive is superior to single modified cornstarch granule (YSQ) or beta- cyclodextrin (HH) in terms of absorption property; dualistic or ternary composite filter prepared by adding the additive to a filter element of a cigarette filter can effectively reduce delivery volume of tar, phenol, hydrocyanic acid and carbon monoxide in smoke gas and improve organoleptic quality of the cigarette, effectively improve sensory comfort of the cigarette, enhance intensity of cigarette aroma, thus enjoying good application prospect.

Description

A kind of macroporous microporous hybrid starch granule and its preparation method and application technical field The invention belongs to the technical field of cigarette additives, and in particular relates to macroporous and microporous hybrid starch granules. At the same time, the invention also relates to the preparation method of the granules and the application in cigarettes. Background technique The advent of filter cigarettes in the 1960s effectively reduced the tar content of cigarette smoke. The contribution of cigarette filters to reducing harmful components such as tar and nicotine in cigarettes lies in the mechanical filtration of particulate matter in the smoke by the filter rod. When the cigarette is smoked, the smoke enters the mouth through the filter, and the particulate matter in the smoke After passing through the fiber filter, it is trapped by the cellulose acetate and cannot be returned to the air stream. Therefore, the effect of cigarette filter ...

AI Technical Summary

Problems solved by technology

Although these microporous filter materials can reduce the particulate phase substances and some volatile gas phase substances in cigarette smoke, there are still the following deficiencies: ① Activated carbon will cause a significant reduction in the smoking quality of flue-cured tobacco cigarettes, and it will affect the smoke in the smoke. Unsatisfactory adsorption of harmful gas phase components such as CO and phenol

②Molecular sieve structure is not easy to control, nor can it maintain cigarette flavor

However, there is no filter material that can meet this requirement simultaneously in the prior art
