Abstract
[Objective]To optimize ultrasonic-assisted enzymatic extraction of Camellia oleifera seed shells pigment.[Method]Using ultrason-ic-assisted enzymatic method to extract the pigment from Camellia oleifera seed shell, optimization of the extraction conditions by single factor and response surface test were done.[Result]The optimum condition for extraction was that the enzyme dosage was 0.8%,the liquid solid ra-tio was 20:1(g:mL),the ultrasonic time of extraction was 15 min,the ultrasonic power of extraction was 90 W,the ultrasonic temperature of extraction was 60 ℃.The absorbance value of Camellia oleifera seed shell pigment measured under this circumstance was 2.765.The pigment absorbance of Camellia oleifera seed shell was improved 1.8 times and 1.5 times by enzyme-assisted ultrasonic method compared to enzymatic method and ultrasonic extraction method.[Conclusion]The study optimizes ultrasonic-assisted enzymatic extraction condition of Camellia oleif-era seed shells pigment, and provides scientific basis for the further research and development of the natural pigment of Camellia olifera seed shell.关键词
