Preparation method for coffee and natural plant powder composite particles and application of coffee and natural plant powder composite particles to cigarette filters

Abstract

The invention discloses a preparation method for coffee and natural plant powder composite particles and application of the coffee and natural plant powder composite particles to a cigarette filter. The preparation method includes: uniformly mixing coffee powder, sweetening natural plant powder and porous corn starch according to a certain proportion, moistening the mixture with deionized water containing reducing sugar, and then performing wet granulation, microwave setting, microwave drying and sieving to obtain high-strength natural products, namely power composite porous starch crystalline particles. The particles are loaded in the cigarette filter to prepare a binary or ternary composite filter, so that content of harmful ingredients such as tar and CO in smoke can be lowered, cancerogens of benzo[a]pyrene, phenol and the like are reduced, and content of unique coffee volatile fatty acids in the smoke can be increased. Cigarette sense organ smoke panel tests show that by adding the coffee and natural plant powder composite particles in the filter, aroma of the cigarette smoke can be enhanced, aroma quality and harmony are improved, offensive odor and irritation are reduced, sweet feeling is added, and inherent quality of a cigarette is improved integrally.

Description

technical field [0001] The invention relates to the technical field of cigarette material preparation, in particular to a method for preparing composite particles of coffee and natural plant powder and its application in cigarette filters. Background technique [0002] The widespread prevalence of tobacco is a global problem with serious consequences for public health, so smoking and health issues are important issues worldwide. At present, there are more than 1 billion smokers in the world, among which there are about 350 million smokers in China, accounting for 35% of the global total. The World Health Organization Framework Convention on Tobacco Control (WHO FCTC) calls for the promotion of tobacco control measures based on consideration of current and relevant scientific, technical and economic issues. Due to the large number of smoking consumers, a comprehensive smoking ban cannot be realized temporarily. Reducing the harm of cigarette smoke to the human body has becom...

Problems solved by technology

However, these methods have defects such as low yield of porous starch granules, poor strength, and potential safety hazards in the chemical binders used, which seriously restrict their application in cigarettes.

CN103054181A discloses a filter rod material of coffee or cocoa powder composite particles and its preparation method, but this method has a method of directly adding coffee or cocoa by crushing, the technology is simple and relatively rough, the aroma of coffee is easy to lose, and it is difficult to ensure the stability of aroma

CN103271443A discloses a preparation method of coffee starch composite granules and its application in cigarette filters. Compared with the aforementioned patents, it has a greater improvement in maintaining the aroma of coffee granules, but its granule preparation process uses coffee and kudzu root directly crushed Granulated by traditional methods, the combination of coffee and starch is relatively simple, and the granules lack micropores to absorb harmful substances in smoke, so the interception effect on harmful substances in smoke is not strong; in addition, although the prepared coffee granules have coffee aroma, they cannot Effectively remove some of the dryness and astringency in the aroma of coffee, so that sometimes there is a little numbness on the tongue during the process of making cigarettes and smoking
