油菜蜂花粉酵母发酵破壁工艺研究

The broken-wall crafts for rape bee pollen using yeast fermentation

采用干性酵母对油菜蜂花粉进行破壁,通过单因素和正交实验得到最佳的破壁条件为干性酵母添加量1%、花粉:水=1:1(g:mL)、发酵时间3d、发酵温度32℃。此条件下,花粉破壁率达到52.30%,破壁花粉营养成分分析表明可溶性糖2.74%、游离氨基酸5.10%、总黄酮1.45%、Vc156.24μg/g。破壁花粉呈淡黄色,具有浓厚的醇香味和淡淡的酸味。

The rape beepollen wall was broken by yeast fermentation was studied in this paper.The best broken-wall conditions were attained by single factor and orthogonal experiment.The result indicated that when the yeast addition was 1%,the beepollen-water ratio was 1：1,at 32 ℃ for 3 d,the breakage rate was 52.30%,and the results of nutrient components showed that the yield of soluble sugar,free amino acids,flavones and vitamin C were 2.74%,5.10%,1.45% and 156.24 μg/g,respectively,which showed strong mellow taste and light acidity.
