摘要
研究菠萝皮色素浸提工艺,旨在促进菠萝皮的综合利用。通过单因素和正交试验确定有机溶剂浸提菠萝皮干粉和鲜皮2条工艺;通过对比,选择干粉色素浸提工艺并采用响应面进一步优化工艺参数,确定最终优化工艺为浸提溶剂75%乙醇,料液比1:60(g/mL),温度70℃,破碎度过10目,浸提级数2级,1级2h,2级0.5h。采用此工艺得到的菠萝皮油溶性色素粗品色价E1%1cm415nm=9.031,其总类胡萝卜素含量为3.149mg/g;水溶性色素粗品色价E1%1cm280nm=7.413,其总黄酮含量为2.451mg/g;黄酮粗品总黄酮含量为245.966mg/g。
In order to achieve the comprehensive utilization of pineapple peel,the extraction process of pigment from pineapple peel was studied.By single factor and orthogonal tests,2 organic solvent extraction process route of both fresh and dry pineapple peel were determined.By contrast,the process route of dry pineapple peel was chosen and its process parameters were further optimized using the response surface method,the ultimate optimal process was：75 % ethanol as extraction solvent,solid and liquid ratio 1：60（g/mL）,extraction temperature 70 ℃,degrees of fragmentation：through 10 meshes,the number of extraction cycles：2,extraction time of cycle 1：2 h,cycle 2：0.5 h.The products got by applying this process were as follow：oil-soluble pigment from pineapple peel,colour value：E1 %1 cm415 nm=9.031,its total content of carotenoids：3.149 mg/g;water-soluble pigment from pineapple peel,colour value：E1 %1 cm280 nm =7.413,its total content of flavonoids 2.451 mg/g;flavone from pineapple peel,its total content of flavonoids：245.966 mg /g.
