Abstract

The invention discloses a cigarette filter stick additive capable of reducing phenol content in main stream smoke, a preparing method and application thereof. The cigarette filter stick additive is a capsule formed by alginate encapsulating propylene glycol alginate. The preparing method comprises the steps of dropwise adding a solution containing propylene glycol alginate and sodium alga acid into a solution containing calcium ions, conducting static settlement and solid-liquid separation, and drying the materials to obtain the cigarette filter additive capable of reducing the phenol content in the main stream smoke. The cigarette filter stick additive is good in chemical stability and is safe for human body, and the addition of the additive in the cigarette filter stick can effectively reduce the phenol content in the main stream smoke; in addition, the preparing technological process and operation of the filter stick additive are simple, thus meeting industrialized production.

Description

technical field [0001] The invention relates to a cigarette filter rod additive, in particular to a cigarette filter rod additive capable of reducing phenol content in mainstream smoke, a preparation method thereof and application in cigarettes, belonging to the field of cigarette manufacturing. Background technique [0002] Cigarette combustion is a complex reaction. As one of the main components in smoke, there are 40 kinds of phenolic compounds, the most important of which include phenol and catechol. The phenolic compounds in cigarette smoke mainly come from the polyphenols in tobacco leaves. Cleavage of phenolic compounds (chlorogenic acid and rutin), there is evidence that the presence of phenolic substances can significantly increase the carcinogenic activity of polycyclic aromatic hydrocarbons, especially phenol, o, m, hydroquinone, o, m, p Cresols are the most harmful phenols. Among them, catechol in the smoke condensate can assist in promoting cancer, and some phen...
