Problems solved by technology

Tobacco is a special consumer product. Smokers mainly obtain physical and psychological satisfaction by smoking the smoke produced by burning tobacco. Therefore, the sensory characteristics of tobacco are the product quality that consumers especially value. There is no such thing in the prior art. Research on improving the sensory properties of tobacco products with laminarin

Abstract

The invention discloses a method for extracting and separating laminarin with low molecular weight and application thereof in cigarette products. The laminarin with the low molecular weight organic acid is extracted by adopting an organic acid method. After kelps are smashed, the laminarin with the low molecular weight organic acid is obtained through organic acid extraction, ultra-filtration, concentration and ethanol fractional precipitation and separation, the molecular weight of the laminarin is less than 10000 Dalton, and solid powder is light brown. The method for extracting and separating the laminarin with the low molecular weight is simple and suitable for industrialization production, the obtained laminarin with the low molecular weight serves as a cigarette ingredient to be applied to cigarettes, smoking quality is improved remarkably, miscellaneous gases are removed effectively, fragrance is improved and embellished to be fine and smooth, smoke is soft, smoke quality is improved obviously, stimulation to nasal cavity, throat and the like is reduced, and the laminarin has positive effect.

Description

Technical field [0001] The invention involves deep processing technology of the kelp. It is specifically for low -molecularly measured polysaccharide extraction methods and its application in tobacco. It belongs to the field of food and biotechnology. Background technique [0002] Laminaria Japonica, known as Kunbu, is a marine plant with high consumption and medicinal value, contains a variety of active substances that are beneficial to the human body, including active polysaccharides, trace minerals, vitamins, etc., which have antioxidant and anti -anti -anti -resistanceRadiation, blood lipids, blood sugar, regulating immune function and other health functions.In addition, kelp is rich in resources and low prices in my country, so it is a potential food resources.At present, kelp polysaccharides have been developed and applied to functional food, medicine, biology, materials and other aspects.For example, Yantai Destin Sumin Ocean Biotechnology Co., Ltd. (China Patent Applicati...
