摘要
采用碱法浸提工艺从破壁酵母中提取碱不溶性β-葡聚糖,通过正交实验得出其最佳提取条件为:碱处理温度75℃,碱处理时间15min,碱液浓度0.75mol/L。不同脱水和干燥条件的对比实验表明,脱水和干燥条件对产品色泽的影响显著。产品最终含水率越低,产品色泽越白;溶剂和水分蒸发得越快,产品颜色越白。
The technology for extracting the alkali-insoluble β-glucans from yeast hy alkali method was studied. The result indicated that the extraction with 0.75 mol/L NaOH at 75 ℃ for 15 min is better. The results also indicated that, for the luster of product, the dehydration and the dry condition are the main factors. The more quickly the solvent and water evaporate ,the better the luster of product is.
