摘　　要： 以菠萝皮渣为原料,通过正交实验研究乳酸发酵菠萝皮渣制备膳食纤维的最佳工艺。结果表明,乳酸发酵菠萝皮渣制备膳食纤维的最佳工艺条件是:料液比1∶18g/mL,接种量15%,发酵温度37℃,发酵时间28h;得到的菠萝皮渣膳食纤维中总膳食纤维含量为80·56%,灰分4·83%,总糖含量0·16g/100g,可溶性膳食纤维(DF)的含量为10·06%,持水性和溶胀性也分别达到了8·95g/g和7·26mL/g,属高活性膳食纤维,适合于添加到多种食品中。 The lactic acid fermentation conditions for production of dietary fiber from pineapple peel were studied by the orthogonal experiment. It was showed that the optimum fermentation conditions were：solid-liquid ratio 1∶18g/mL, lactic acid bacteria inoculums ratio 15%,fermentation temperature 37℃ and fermentation time 28h. Total diet fiber content,ash,total sugar content of the products was 80.56%,4.83% and 0.16g/100g respectedly,soluble dietary fiber（DF）content was 10.06%,water-holding capacity and swelling capacity were 8.95g/g and 7.26mL/g. It belongs to a highly active dietary fiber,suitable for adding to the variety of foods.
