Technical Field

The invention relates to the technical field of cigarette filter sticks, in particular to a binary composite filter stick containing collagen recombinant particles.

Background

Along with the improvement of living standard, the health consciousness and the environmental protection consciousness of consumers are gradually enhanced, and cigarette consumers pay more and more attention to the smoking safety of cigarettes. Therefore, the development of low-harm cigarette products is receiving extensive attention. In addition to the well-known tar, seven more important harmful components such as carbon monoxide, ammonia, hydrocyanic acid, benzopyrene, phenol, NNK, crotonaldehyde and the like are recognized in the industry. In addition, toxic heavy metals such as arsenic, lead, chromium, cadmium, mercury, nickel and the like in the mainstream smoke can enter a human body in the form of aerosol or metal oxide and the like, and the toxic heavy metals are harmful to the human body after being accumulated to a certain degree. At present, the heavy metal elements are also listed in the list of harmful components in cigarette smoke.

In recent years, around the problems of release and harm of harmful components in cigarette smoke, industry researchers have proposed some harm reduction technologies, wherein an adsorption and interception technology based on cigarette filter sticks is one of research hotspots. By adding various functional materials such as activated carbon, molecular sieve, montmorillonite, zeolite, chitosan, tea polyphenol, Chinese herbal medicine extract, soybean protein polypeptide and the like into the common filter stick, the prepared composite filter stick can selectively absorb harmful ingredients in smoke, so that the safety of cigarettes is improved. For example, patent 201110174733.3 reports a safety cigarette, which can remarkably reduce the toxicity of cigarette smoke and improve the safety of cigarette products by adding short peptide collagen into tobacco shreds during the cigarette manufacturing process. Patent CN103071454A introduces a seaweed active carbon filter additive, and a composite filter prepared by using the active carbon can obviously reduce the release amount of heavy metals such as chromium, nickel, arsenic, cadmium, lead and the like in mainstream smoke and has the special fragrance of seaweed. Patent CN203748660U has designed a compound aluminum bar that contains heavy metal filter segment, and the filter segment contains fibre silk bundle and distributes the mesoporous titanium dioxide composite material granule on the silk bundle, and this kind of novel compound filter rod can reduce cigarette smoke heavy metal release volume under the condition of guaranteeing original taste of cigarette and smoking quality. CN103506092A prepares a load type polyamide-amine dendritic polymer adsorbent, and after the adsorbent is used for a cigarette composite filter stick, only a small amount of the adsorbent needs to be added, so that the adsorbent has a large adsorption capacity and a strong adsorption capacity for heavy metals in smoke. CN102499479A takes silica gel, alumina, molecular sieve or cellulose acetate as a carrier, obtains a complexing adsorbent by loading natural amino acid, and the binary composite filter stick prepared by adding the complexing adsorbent into a cigarette filter stick can effectively reduce the heavy metals of cadmium in the mainstream smoke of cigarettes by 15-40% and arsenic by 5-20%, and does not influence the smoking taste of the cigarettes.

Although the research results of the above patents show a certain harm reduction effect, there are some disadvantages. For example, the active carbon and the mesoporous composite material have no adsorption selectivity to smoke components, and can adsorb cigarette fragrance components while reducing the content of harmful components of cigarettes, so that the smoking taste of the cigarettes is deteriorated; the preparation process of the dendritic functional polymer adsorbent and the amino acid supported complex adsorbent is complicated and the cost is high.

Researches show that the safe natural renewable biological material with better biodegradability is a novel material with great research value, and the research and development of the material for reducing the harm of the cigarettes based on the natural renewable biological material have extremely high market popularization prospect. Collagen is a natural biological macromolecule, widely exists in animal bones and skins, is a common animal biomass resource, is safe and renewable, and has proper price. The molecular structure of the collagen contains a large number of polar groups such as peptide bonds, amino groups, carboxyl groups, hydroxyl groups and the like, and the existence of the groups is helpful for adsorbing and removing harmful ingredients in cigarette smoke. According to the patent 201821820383.7 and the patent 201821819365.7, collagen polypeptide is introduced into a common filter stick, a collagen binary composite particle filter stick and a collagen fragrance injection filter stick are respectively prepared, and based on a special molecular structure and numerous active groups of collagen, the cigarette sensory quality is improved, the tar and CO content is reduced to a certain extent, and the cigarette filter stick has certain application potential. However, the effect of removing harmful components by adsorption is limited only by using collagen polypeptide, and the harmful components can be reduced by recombining collagen polypeptide with other functional materials. So far, no report of a binary composite filter stick which is prepared by recombining collagen with materials such as active carbon, ultramicro plant particles and the like and then adding the recombined materials into diacetate fibers to reduce the release amount of harmful ingredients in cigarette smoke exists at home and abroad.
