摘要
菠萝皮中提取果胶,在前期开展了一系列单因素试验,初步明确了各因素对果胶提取过程的影响趋势。在此基础上,为进一步优化提取工艺,采用L_(9)(3^(4))正交试验设计,系统研究料液比、提取时间、提取温度和pH值这四个关键因素对菠萝皮中果胶得率的具体影响。实验最终结果显示,最佳工艺条件为:离子交换树脂用量设定为5%,料液比为1∶30(g∶mL),浸提温度控制在85℃,浸提液pH值为2.5,浸提时间为2.5 h。在该条件下,果胶得率可达9.92%。与传统的酸提法相比,此工艺下的果胶得率明显更优,这表明离子交换法在菠萝皮果胶提取方面具有显著优势和广阔的应用前景。
Extracting pectin from pineapple peel,a series of single factor experiments were conducted in the early stage to preliminarily clarify the influence trends of various factors on the pectin extraction process.On this basis,in order to further optimize the extraction process,an L_(9)(3^(4))orthogonal experimental design was adopted to systematically study the specific effects of four key factors,namely solid-liquid ratio,extraction time,extraction temperature and pH value,on the yield of pectin in pineapple peel.The final experimental results showed that the optimal process conditions were as follows:ion exchange resin dosage was set at 5%,solid-liquid ratio was 1∶30(g∶mL),extraction temperature was controlled at 85℃,extraction solution pH value of 2.5,and extraction time was 2.5 h.Under these conditions,the yield of pectin can reach 9.92%.Compared with the traditional acid extraction method,the yield of pectin under this process was significantly better,indicating that the ion exchange method had significant advantages and broad application prospects in the extraction of pineapple peel pectin.
