Problems solved by technology

[0004] First, for CO and N in the flue gas X o Y The adsorption of harmful gas phase components such as is not ideal;
[0005] Second, it has a greater negative impact on the smoking quality of flue-cured cigarettes;
[0006] Third, the fragile material is not conducive to industrial processing
[0007] Fourth, the color of the material is single, generally black, white and yellow, and the color cannot be changed, so it is difficult to meet the individual needs of cigarette products
However, there is no good solution in the prior art

Embodiment 1

[0044] 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 one hour, 1 ml of sodium hydroxide with a concentration of 4% was added to terminate the reaction, and centrifuged to obtain slurry-like porous starch. Adopt natural food coloring: beta-carotene aqueous solution (concentration 0.01g / kg) to color the pulpy porous starch. Add 1 g of alum to the colored pulpy porous starch, and then treat it in a 900-watt microwave oven for 1 minute to pulverize the solidified porous starch and pass through a 60-mesh sieve to obtain yellow modified starch granules. 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

[0048] 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, 1.5 mL of 3% sodium hydroxide was added to terminate the reaction, and centrifuged to obtain slurry-like porous starch. The pulpy porous starch is colored by using beet red natural food coloring aqueous solution (food coloring concentration less than 0.01g / kg). Add 1g of alum to the colored pulpy porous starch, and then treat it in a 900-watt microwave oven for 1 minute to pulverize the solidified porous starch and pass through a 60-mesh sieve to obtain red modified starch granules.

Embodiment 3

[0050] 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 enzymolysis, 1.0 ml of 5% sodium hydroxide was added to terminate the reaction, and centrifuged to obtain slurry-like porous starch. The slurry-like porous starch is colored by using an aqueous solution of natural food coloring sodium copper chlorophyllin (the food coloring concentration is less than 0.01 g / kg). Add 1g of alum to the colored pulpy porous starch, and then treat it in a 900-watt microwave oven for 1 minute to pulverize the solidified porous starch and pass through a 60-mesh sieve to obtain green modified starch granules.

Abstract

The invention discloses a color modified starch granule, the preparation method and the application thereof. The 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, colorizing, microwave drying, pulverizing and sieving to obtain the desired color modified starch granule. The color 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 color 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 colored 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. ...
