Abstract

The invention discloses a method for extracting and separating capsaicin and capsanthin, which comprises the following steps: carrying out carbon dioxide supercritical extraction on capsicum skin powder to obtain capsicum oleoresin, and carrying out molecular distillation to separate the capsicum oleoresin to obtain capsaicin and capsanthin. The method has the advantages of simple operation, shortextraction time, high product yield, high product purity, and substantial saving of the production cost; and no organic solvent is used, so that the pollution to the environment in the production process is reduced, new impurities and toxic substances are not brought in, the pure natural quality of the product is ensured, and the method is suitable for industrial mass production.

Description

technical field [0001] The invention relates to the extraction and separation technology of capsaicin and capsanthin, in particular to a method for extracting and separating capsaicin and capsanthin. Background technique [0002] Capsaicin is also known as capsaicin. In nature, it exists in Capsicum annuum (Capsicum annuum) and its variants. It is precipitated from petroleum ether as monoclinic, rectangular flakes, with a melting point of 64-68°C. The boiling point is 210-220°C (1.33Pa). The maximum ultraviolet absorption is at 227nm, 281nm (ε7000; 2500). It is an extremely pungent vanillyl amide alkaloid. Capsaicin is a white crystalline powder and is the active ingredient of capsicum, a plant in the genus Capsicum. [0003] Capsanthin, also known as capsanthin, is a natural colorant extracted from peppers. The main coloring components are capsanthin and capsanthin, which belong to carotenoids, accounting for 50% to 60% of the total. In addition, it also contains a cer...
