菊花酸奶的研制

Development of chrysanthemum yoghourt

为了提高酸奶的保健功能,以菊花和奶粉为主要原料研制菊花保健酸奶。采用水提法得到菊花的提取液,从菊花浸提的最佳条件、菊花汁添加量的确定,菊花酸奶的最佳配方3个方面研究了菊花酸奶的制作工艺条件。结果表明,菊花最佳浸提条件为粉碎后过60目筛,浸提温度为100℃,浸提时间1.5 h,料液比1︰40;菊花保健酸奶的最佳配方:菊花汁添加量为20%,接种量4%,加糖量8%(均为质量分数),发酵时间4 h。

In order to improve the health function of yoghourt, chrysanthemum yoghourt was made using chrysanthemum extracting solution and powdered milk as materials. The preparation technology of chrysanthemum yoghourt was studied including the best condition of chrysanthemum extracting with water, the suitable adding dose of chrysanthemum extracting solution and the best prescription of chrysanthemum yoghourt. The results were as follows： chrysanthemum was comminuted and sifted out 60-mesh sieve. The chrysanthemum powder was extracted at 100 0（2 in water for 1.5 h. The ratio of chrysanthemum powder and water was 1：40. The best prescription of chrysanthemum yoghourt was that suitable adding dose of chrysanthemum extracting solution was 20%, inoculums concentration was 4%, the adding dose of sugar was 8% （all mass fractions） and the fermentation time was 4 h.
