AI Technical Summary
Prior Art When separating capsicin and other carotenoids from chili oleoresin, conventional saponification methods are usually carried out at high temperatures, resulting in significant losses of these heat-unstable compounds, and lacking effective separation methods under mild conditions.
The low-temperature saponification method was used to treat the pepper oleoresin at ambient temperature of 50°C using propylene glycol and ethanol potassium hydroxide solution. The capsicum oleoresin, β-carotene, β-cryptoxanthin and zeaxanthin were then separated by solvent extraction and crystallization, avoiding the influence of alkali and heat at high temperatures.
The separation of high-purity capsicum eretinol and other carotenoids is achieved, avoiding the degradation of esterides at high temperatures, and improving the separation efficiency and product purity.
