Embodiment 1

[0040] Take 20g starch, add 40mL, 0.1mol / L, acetic acid buffer solution with a pH value of 3.5, stir evenly at 50°C, prepare starch milk, add 0.2g glucoamylase, and stir at 50°C for enzymolysis for 20 After 1 hour, add 1 ml of sodium hydroxide with a concentration of 4% to terminate the reaction, centrifuge to obtain a slurry-like porous starch, add 1 g of alum to the slurry-like porous starch, and then process it in a 900-watt microwave oven for 1 minute to pulverize the solidified porous starch. After a 60-mesh sieve, the desired modified starch granules are obtained. The particles were determined to be superior to activated carbon in terms of adsorption properties. The measurement results are shown in Table 1.

Embodiment 2

[0044] Take 20g of starch, add 50mL, 0.3mol / L, acetic acid buffer solution with pH value of 4.0, stir evenly at 40°C, prepare starch milk, add 0.4g of glucoamylase, and stir at 40°C for enzymolysis After 20 hours, add 1.5mL of 3% sodium hydroxide to terminate the reaction, centrifuge to obtain a slurry-like porous starch, add 1g of alum to the slurry-like porous starch, and then treat it in a 900-watt microwave oven for 1 minute to pulverize the solidified porous starch , after passing through a 60-mesh sieve, the desired modified starch granules are obtained.

Embodiment 3

[0046] Take 20g of starch, add 60mL of 0.5mol / L acetic acid buffer solution with a pH value of 5.0, stir evenly at 55°C, and prepare starch milk with a certain concentration, add 0.5g of glucoamylase, and stir at a constant temperature at 55°C After 24 hours of enzymatic hydrolysis, add 1.0ml of 5% sodium hydroxide to terminate the reaction, centrifuge to obtain slurry-like porous starch, add 1g of alum to the slurry-like porous starch, and then treat it in a 900-watt microwave oven for 1 minute, pulverize and solidify the starch. The porous starch is passed through a 60-mesh sieve to obtain the desired modified starch granules.

Abstract

The invention discloses modified starch granules, the preparation method and the application thereof. The preparation method comprises the following steps: stirring starch and acetic buffer solution uniformly, adding saccharifying enzyme for enzymolysis reaction, adding sodium hydroxide solution to stop the reaction, centrifugally separating to obtain paste-shape porous starch, microwave drying, pulverizing and sieving to obtain the desired modified starch granule. The modified starch granule is superior to active carbon in adsorption performance, and can be added into the filter core of a cigarette filter to prepare a binary or ternary filter, which can effectively reduce the delivery amount of tar and carbon monoxide in the smoke, improve the cigarette sense quality, effectively improve the cigarette sense comfort and improve the centralization degree of the cigarette smoke. The modified starch granule has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of cigarette material preparation, and in particular relates to a modified starch granule used for cigarette filters. At the same time, the invention also relates to the preparation method and application of the particle. 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 Immediately after contact with the filter fiber tow, it is stuck and cannot be returned to the air stream. Therefore, the effect of cigarette filter on reducing harmful components such as tar and nicotine is the most significant and effective. [0003]...
