Description

Preparation method of elderberry tablet candy and elderberry extract
Technical Field
The invention relates to the technical field of functional food processing, in particular to a preparation method of an elderberry tablet candy and an elderberry extract.
Background
Anthocyanins, also called anthocyanidins, are water-soluble flavonoid compounds which can change color with the acid and alkali of cellular fluid and are one of the main pigments forming the color of petals and fruits. The anthocyanin is a secondary metabolite of plants, and researches show that the anthocyanin has an oxidation resistance effect which is fifty times higher than that of vitamin E and twenty times higher than that of vitamin C, is a natural antioxidant and has extremely high bioavailability. In addition, anthocyanin also has various biological activities of resisting fatigue, aging and tumor, preventing cardiovascular and cerebrovascular diseases and the like, and is widely applied to industries such as functional food, cosmetics, pharmacy and the like at present.
The elderberry is the berry of elderberry of Caprifoliaceae, is bitter, pungent and mild in flavor, is red or blue-violet black oval or nearly round, is rich in polyphenol substances and phytochemicals, can resist viruses, bacteria, nasal mucositis, diuresis, sweating promotion and the like, and the anthocyanin in the elderberry has the functions of helping to regulate immune response and enhancing human body resistance. The anthocyanin in the elderberry is mainly an anthocyanin substance taking cyanidin as a main component and an anthocyanin substance taking cyanidin as an aglycone, and is one of the plant sources containing more anthocyanin at present. Johansen isolated 4 anthocyanins from the fruit of sambucus canadensis. Nakatani et al isolated 2 novel acylated anthocyanin compounds from the fruit. At present, researches on anthocyanin at home and abroad are mostly concentrated on crops such as blueberries, purple potatoes, mulberries, black barbary wolfberry fruits and the like, and few reports are made on researches on extraction processes of the anthocyanin of the blackberries.
At present, the common method for extracting the anthocyanin is an organic solvent extraction method, the solvent is alcohol solution such as ethanol or methanol, the extraction rate can be improved by adding a small amount of hydrochloric acid or acetic acid solution, an ultrasonic auxiliary method, a microwave auxiliary method and the like, the method is simple and convenient to operate, and complex instruments and equipment are not needed; however, the use of a large amount of organic solvents during extraction results in increased production cost, easily damaged active ingredients, and poor safety due to environmental pollution caused by certain toxicity of solvents such as methanol.
Generally, mature plant cell walls are composed of cellulose, hemicellulose, pectin, and lignin. The principle of the enzymatic extraction is that hydrolytic enzymes such as cellulase, pectinase, hemicellulase and the like are used for decomposing plant cell walls, destroying cell structures and promoting the diffusion and leaching of functional components, so that the extraction rate is improved. And the enzyme extraction is carried out at a lower temperature, so that the effective components can be well protected from being damaged. The solid state fermentation refers to a fermentation process in which a reaction system is anhydrous or close to anhydrous, the treatment process of the raw materials is relatively simple, and the damage to the nutrient components and the sensory characteristics of the raw materials is small. In the fermentation process, macromolecular fibers, organic acids, pectin and other substances are fermented by microorganisms to form rich amino acids, enzymes, vitamins, mineral substances and secondary metabolites, so that the nutrition is rich and the absorption by a human body is facilitated. At present, no report about the enzymatic extraction of the elderberry anthocyanin and the preparation of the elderberry extract by using a fermentation method exists.
