turmeric extract powder

Lycopene extraction and separation methods mainly include organic solvent extraction, enzyme reaction method, microorganism fermentation, synthetic method, supercritical CO2 extraction, microwave method, etc. The solvent stesweet stevia extraction method is one of the most traditional (extraction), but the traditional leaching method exists leaching time is long, the intensity of labor, raw materials and processing energy consumption big, shortcomings and so on heat sensitive components easily damaged. Chemical synthesis of lycopene contains a variety of isomer and impurities, banned use in health care products, market share has decreased; Natural extraction is limited by the raw material, and is difficult to further reduce the cost and production significantly influenced by season. Therefore, development of microbial fermentation production method presents obvious advantages in recent years.
Lycopene is widely naringenin price distributed in nature. At present, people gradually realized the synthetic pigment, the harm of human body from the natural plant extracting lycopene method become more common.
Organic solvent extraction
Principle: lycopene is one kind has 11 carbon carbon fatty hydrocarbons unsaturated double bond, it is not soluble in water, soluble in methanol, ethanol, soluble in ether, petroleum ether, hexane and acetone, soluble in chloroform, carbon disulfide, benzene and other organic solvents. According to the nature, can use lipotropy sexual organic solvent extracting lycopene from tomato.
Technological process: mash tomatoes - > to turmeric extract powder drying, crushing, organic solvent extraction to extract and filter, the filtrate to concentrate, crude products Extraction of pH, extraction temperature, extraction time is the most important factor affecting the effects of extraction. Less organic solvent extraction equipment, simple technology, convenient operation, but due to also contain other elements in the tomato, and organic solvents have trace residues. Merely by solvent extraction, the product purity is not high, generally around the lycopene content of 5% to 15%, and often does not produce lycopene crystals, but an oily substance, the tomato red oil dementholized resin.
Supercritical carbon dioxide extraction
Principle: the material under high pressure, liquid phase and gas phase difference is narrowing, reaches a certain temperature and pressure, loss of merged into one phase, the state becomes critical point, the temperature and pressure at this time is called the critical temperature and critical pressure respectively, when the temperature and pressure exceeds the critical point, the nature of the fluid between liquid and gas, called a supercritical fluid. Supercritical fluid has the characteristics of gas and liquid duality, both with gas is quite high permeability and low viscosity, and close to the liquid density and excellent dissolving capacity for material things. It can extract useful elements from the raw material, so as to realize the separation of need, especially suitable for heat-sensitive ingredients such as lycopene.
Technological process: fresh red tomato raw material to pumpkin seed extract beating to press filter, vacuum drying, crushing, sieving to weighing, extraction tank, seal to control the suitable working parameters, static, dynamic extraction separation and step-down to lycopene, which is obtained by separation column, product quality testing.
