Abstract
The invention discloses a method for increasing the yield of a color value of capsanthin. The method comprises the following steps of: extracting hot pepper particles, concentrating, obtaining capsanthin crude extract after removing a residual solvent, and obtaining the capsanthin by removing the pungency of the capsanthin crude extract; and extracting the hot pepper particles by adopting an extracting solvent to which a natural antioxidant is added in the extraction process. According to the method, the antioxidant is added to the extracting solvent so that on the one hand, the antioxidant consumes dissolved oxygen in the solvent so as to reduce the impact of the dissolved oxygen on the capsanthin, and on the other hand, the antioxidant can be fully in contact with the hot pepper particles in the extraction process so as to fully take effect, thereby the yield of the color value of the capsanthin can be effectively increased. The method is simple in technology and convenient to operate, has the obvious effect on the increasing of the yield of the color value of capsanthin and can realize the industrial production.
