Description

Cigarette paper capable of adjusting pH value of smoke and preparation method thereof
Technical Field
The invention relates to the field of cigarette auxiliary materials, in particular to cigarette paper for adjusting the pH value of smoke and a preparation method thereof.
Background
The organic acid plays an important role in the tobacco growth process and has important influence on the quality of cigarettes, and although the content of the organic acid is low, the organic acid has far greater influence on the sensory quality of the cigarettes than polybasic acid and higher fatty acid. Organic acids have a considerable influence on the smoking comfort of cigarettes, such as neutralization of smoke, reduction of irritation, and influence on the aroma and taste of cigarettes. The cigarette smoke mainly refers to cigarette mainstream smoke, the acidity and alkalinity of the cigarette smoke are indexes reflecting the quality of cigarettes, and chemical compositions and chemical balance in the cigarette smoke can be comprehensively reflected. The pH value of the smoke can represent the acid-base equilibrium state of organic and inorganic components when the cigarette is burnt, and can reflect the smoke intensity, the irritation and the sensory quality of cigarette smoking. Therefore, the pH value of the smoke can be adjusted to have important influence on the acid-base balance of the smoke, the aroma quality, the main stream smoke components and the smoking quality.
The organic acid includes volatile organic acids and non-volatile organic acids. Volatile organic acid can be directly volatilized into smoke in the smoking process of the cigarette, and obvious influence is generated on taste and aroma. The non-volatile organic acid can adjust the pH value of the smoke, so that the taste is mellow, the smoke concentration is enhanced, and the tobacco fragrance is indirectly influenced. When the acid substances are directly added on the cigarette paper in the prior art, the organic acid reacts with calcium carbonate in the cigarette paper to cause great fluctuation of air permeability of the cigarette paper, and in addition, stronger acidity also causes certain corrosion to papermaking equipment. These reasons also limit the large scale application of organic acids to cigarette paper.
