Description
Technical Field
The invention relates to the technical field of dropping pills for cigarettes, in particular to a water-soluble dropping pill prepared from a porous material and a preparation method thereof.
Background
Adding a moistening and fragrant dropping pill into a filter stick of a cigarette becomes a common means for improving the taste of the cigarette for each large cigarette brand, and the traditional moistening and fragrant dropping pill is mostly oil-soluble, namely oil-soluble essence and spice are taken as inner layer materials of the dropping pill, and oil solvents such as olive oil, caprylic capric glyceride and the like are taken as diluting solvents of the essence and spice. For example, Chinese patent CN201810269876.4 discloses an essence containing coffee molecules, a dropping pill for tobacco and a preparation method of the dropping pill for tobacco. The coffee essence comprises the following components in parts by mass: 5-12 parts of coffee extract; 1-5 parts of auxiliary spice; 1-5 parts of a softening agent; 5-15 parts of a solvent. The solvent is a mixture of edible blend oil and caprylic/capric glyceride. Chinese patent CN201810269647.2 discloses an essence containing Dendranthema indicum essential oil, a dropping pill for tobacco and a method for preparing the dropping pill for tobacco. The essence containing the Dendranthema indicum essential oil is prepared from the following raw materials in parts by weight: 0.8-1.5 parts of Dendranthema indicum essential oil, 1.2-2.0 parts of linalool, 0.2-0.8 part of geraniol, 1.2-1.8 parts of benzyl alcohol, 0.2-0.6 part of alantolactone, 1.5-2.5 parts of linalyl acetate, 0.5-0.8 part of ethyl ionone and 89.5-95.5 parts of solvent, and the obtained product is taken as the essence of the dropping pill for cigarettes to prepare the dropping pill for cigarettes containing the essence of Dendranthema indicum essential oil. The solvent is edible blend oil or caprylic capric glyceride.
The oil solvent used by the oil-soluble dripping pill has certain inherent smell and is difficult to coordinate with the smoke fragrance; in addition, most of the essence and flavor for cigarettes are water-soluble substances, and the solubility of the essence and flavor in an oil-soluble solvent is poor, so that the application of most of the water-soluble essence and flavor in oil-soluble dropping pills is limited. On the other hand, the oily solvent is easy to pollute cigarette filter stick tows after seeping out, and may permeate into the filter stick wrapping paper, so that the appearance of the cigarette is influenced, and the smoking experience of consumers is reduced. Therefore, development of water-soluble dropping pills becomes an important direction for research of cigarette enterprises, water is used as a solvent of essence and spice, smoke and cigarette fragrance are not affected, overflowed water can moisten smoke and reduce irritation after the dropping pills are pinched broken, and smoking quality of cigarettes can be improved.
At present, there are many researches on water-soluble dripping pills, for example, chinese patent CN201410059720.5 discloses a three-layer water capsule for cigarettes and a preparation method thereof. The capsule takes water-soluble essence as an inner layer, and water is used as a solvent to dilute the essence; the middle layer is sodium alginate complex to wrap water and essence, and the third layer is waxy material to prevent water from permeating into the capsule. Chinese patent CN201711263263.1 discloses a dropping pill for tobacco and a preparation method thereof. Comprises calcium chloride, calcium lactate and water-based essence, which are gradually mixed and frozen, and then are respectively dipped in forming liquid and shaping liquid to obtain the dropping pill for cigarettes. The water-soluble dropping pill disclosed by the prior art adopts cross-linked and solidified sodium alginate as a coating layer, and an aqueous solution containing water-soluble essence is directly coated in the coating layer; in the later period of crushing the dripping pills, the aroma of the cigarettes is gradually thin due to the continuous and quick release of the essence components, the aroma release amount cannot be maintained in a stable state, and the requirement of a consumer on the stable, slow and long-time stable release of the aroma of the cigarettes in the cigarette smoking process cannot be met.
