Abstract

The invention discloses a purple grape skin-dried orange peel composite pigment for cigarette paper, and a preparation method and application thereof. The method comprises the steps of respectively extracting the purple grape skin and the dried orange peel by adopting ethanol water solution with specific pH and concentration to obtain extracting solution, adding the dried orange peel extracting solution into the purple grape skin extracting solution, adjusting the pH of a mixed system to 4.0-5.0, stirring at 35-45 ℃ for 0.5-2 hours to perform directional composite reaction, and finally purifying, concentrating and drying the composite reaction solution by using a macroporous adsorption resin column to obtain the product. The compound pigment prepared by the method not only can endow the cigarette paper with stable and elegant purple red color, but also can synchronously release the grape-dried orange peel compound fruit fragrance with rich and coordinated levels during the burning and smoking of the cigarette, thereby realizing the synergy of color stabilization and fragrance enhancement.

Description

Purple grape skin-dried orange peel composite pigment for cigarette paper and preparation method and application thereof Technical Field The invention belongs to the technical field of cigarette paper additives, and particularly relates to a purple grape skin-dried orange peel composite pigment for cigarette paper, and a preparation method and application thereof. Background In the differentiation and high-end design of cigarette products, the functions of cigarette paper exceed the traditional wrapping roles, and become a key carrier for molding unique visual identification of the products and improving sensory experience. Among them, the development of dyed cigarette paper with elegant color and luster and pleasant smell imparted to smoke by using natural pigments derived from plants has become a clear technical trend. Correspondingly, early technological developments followed the core route of "color retention and noise reduction". The route focuses on obtaining high-color-value and high-purity pigment by optimizing the extraction and purification process, and aims at removing impurities such as sugar, pectin and the like in the raw materials, so as to reduce bad breath possibly generated during combustion from the source. However, such a technical model directed to a single physical and chemical index (color value and purity) has a functional limitation inherent in that various flavor substances which naturally coexist with a dye in a raw material and possibly give a pleasant feeling to smoke are generally removed together as impurities in the process of purifying a dye to the best. The direct result is that the obtained product has single function, can be used as a colorant, and can not synchronously provide coordinated aroma, so that the compound function requirement of the market on the color and aroma integration of cigarette paper is difficult to meet. To break through the above limitations, the art developed a technological path of "color and fragrance homology". The idea aims at a specific single plant raw material (such as purple grape skin), and the pigment is efficiently obtained through a customized extraction and purification strategy, and simultaneously, the characteristic flavor substances of the raw material are purposefully and selectively reserved, so that the important progress of cooperatively obtaining the color and the aroma from the single raw material is realized. However, this single raw material based technical path presents a dual challenge when pursuing higher order product quality. First, in the sensory dimension, the aroma spectrum provided by a single raw material is relatively fixed, for example, the purple grape skin mainly presents fresh fruit aroma, the aroma structure is thinner, and the complexity and coordination of the sensory level and satisfaction can be improved. Secondly, in the dimension of the physical properties, the stability challenges faced by natural pigments, represented by anthocyanins, are more pronounced when such extracts are further required to be applied in cigarette paper systems and are required to meet high standards of long-term storage stability and sensory quality uniformity. Under the specific processing and use scene of the cigarette paper, how to further inhibit or delay the degradation and color change of pigment, ensure the long-term stability of the color as early as possible, and become the technical difficulty that the quality of the product must be improved. To enrich the note, one skilled in the art would readily think of combining extracts from different sources of flavor. However, whether the extracts prepared respectively are simply and physically mixed or different raw materials are placed in the same system for conventional co-extraction, most of the components of the obtained product are only in a physical mixing state, and deep fusion and stable combination of molecular layers cannot be realized. This results in an unsynchronized pyrolytic release of the components during smoking of the cigarette, discrete aroma, poor coordination, and inability to provide additional stabilizing effects to the color through interactions between the components. Therefore, when dealing with the challenges of the "color and fragrance source" technology, such as the thin fragrance structure and the insufficient long-term stability of pigments, the existing combination or co-extraction method does not provide a solution for the effectiveness of the system. The present invention has been made to solve the above problems. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a purple grape skin-dried orange peel composite pigment for cigarette paper, and a preparation method and application thereof. In particular, the invention aims to solve the double technical bottlenecks that the existing color and aroma source technology is limited to single raw material, the aroma structure is thin, and the chemical stabi
