Embodiment 1

[0033] Take 20g of cornstarch, add 50ml of acid buffer solution with a concentration of 0.1mol / L and a pH value of 5.0, and stir evenly at 50°C to prepare a mixed starch milk. 0.2 g of glucoamylase was added, and after 20 hours of enzymolysis with constant temperature and stirring at 50° C. and pH value of 5.0, 1 ml of 4% sodium hydroxide solution was added to terminate the reaction. Centrifuged to obtain slurry-like porous starch. After drying the slurry porous starch at 50°C, the macroporous cornstarch YSQ with a pore diameter in the range of 0.5um to 1.5um can be prepared. Take another 20g of cornstarch, add 0.2g of α-amylase to liquefy and pre-hydrolyze, then add 0.2g of cyclodextrin glucosyltransferase to ferment, and after the fermentation product is dried, microbes with a pore size in the range of 6A° to 6.5A° can be obtained. Hole Cornstarch HH. Mix the prepared YSQ and HH in a weight ratio of 0.5:1, spray 5 grams of water per kilogram of starch to moisten it, dry it...

Embodiment 2

[0035] Repeat Example 1 with the following difference: the YSQ and HH prepared are mixed in a weight ratio of 1:1. Pass through a 50 mesh sieve.

Embodiment 3

[0037] Repeat Example 1 with the following difference: the YSQ and HH prepared are mixed in a weight ratio of 1.5:1. Pass through a 60 mesh sieve.

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

technical field [0001] 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 [0002] 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 on reducing harmful components in cigarette smoke is the most significant and effecti...
