摘要: [目的]以酸奶为基础,优化真空冷冻干燥程序,筛选不同种类的果胶和淀粉,制作一款质量和感官俱佳的冻干酸奶块。[方法]采用真空冷冻干燥技术,以冻干酸奶块的外观、感官评价结果为参考标准,通过优化冻干程序,对比添加不同种类的果胶和淀粉对冻干酸奶块的影响,确定最佳生产工艺。[结果]采用较小的升温间隔和较低的终点温度可制得高品质的冻干酸奶块。果胶和淀粉的种类对产品也有较大影响,在本研究的最佳生产条件下,制得冻干酸奶块的蛋白质含量为15.5 g/100 g,脂肪含量为11.4 g/100 g,水分含量为1.4 g/100 g,乳酸菌活菌数为8×108 CFU/g。[结论]本研究为冻干酸奶块的工艺优化及工业生产提供理论支持和参考。

Abstract: [Objective] Based on yogurt,optimized the vacuum freeze-drying process and screened different types of pectin and starch,and made a freeze-dried yogurt block with excellent quality and sensory. [Method] Vacuum freeze-drying technology was adopted. Taking the appearance and sensory evaluation results of freeze-dried yogurt blocks as reference standards. By optimizing the freeze-drying process and comparing the effects of adding different types of pectin and starch on freeze-dried yogurt blocks,the optimal production process was determined. [Result] High-quality freeze-dried yogurt blocks could be produced by using smaller heating intervals and lower terminal temperatures. The types of pectin and starch also had a significant impact on the product. Under the optimal production conditions in this study,the protein content of the freeze-dried yogurt blocks produced was 15.5 g/100 g,the fat content wass 11.4 g/100 g,the moisture content was 1.4 g/100 g,and the viable count of lactic acid bacteria was 8×108 CFU/g. [Conclusion] This study developed a freeze-dried yogurt block with excellent sensory quality,providing a reference for the process optimization and industrial production of freeze-dried yogurt blocks.
