Abstract

A method for refining capsicum oleoresins uses a capsicum oleoresin with a low capsaicinoid content. The method includes selecting 6% to 9% of potassium hydroxide as a saponifying agent, and subjecting the mixture to saponifying processing at a temperature between 40 DEG C and 55 DEG C for 4 hours to 5 hours; preparing hexyl hydride and 85% to 95% of ethanol into a mixed solvent, subjecting saponifying matter to multiple extraction, concentrating the extracted capsicum oleoresin under the vacuum and warming condition, respectively recycling the hexyl hydride and the ethanol, dissolving the capsicum oleoresin through ethanol, subjecting the capsicum oleoresin to secondary extraction, stirring the extracted capsicum oleoresin evenly, separating a pigment phase and a capsaicin phase, separately heating the concentrated capsaicin phase and the pigment phase, and respectively recycling the ethanol and ethyl acetate. The method for refining capsicum oleoresin increases the content of capsaicin in the capsicum oleoresin, reduces the residual amount of capsochrome in the capsicum oleoresin, enables the color to be light, improves the product quality, expands the applied range, increases the additional value of products and, enhances the market competitiveness.

Description

technical field [0001] The invention relates to a method for extracting high-concentration capsaicinoids from capsicum as a raw material. Background technique [0002] Capsicum oleoresin is a by-product, and capsicum oleoresin is a natural food additive. It is widely used in many fields such as food and medicine. The market for capsicum oleoresin with high capsaicin content is scarce. Prior art does not well solve key technologies such as saponification and separation in the extraction process, and the content of capsaicinoids in the obtained capsicum oleoresin is relatively low, generally around 1% to 10%, so that capsicum with lower capsaicinoids content The fields of application of oleoresin are very limited. Contents of the invention [0003] The purpose of this invention is to provide a kind of capsicum oleoresin with lower capsaicinoid content as raw material, at first select suitable saponification agent and saponification condition to carry out sufficient sapo...
