摘要: 本研究将亚硒酸钠添加在活性乳酸菌发酵剂中,通过活性乳酸菌的生物转化,使活性乳酸菌发酵剂富集有机硒,再用活性乳酸菌发酵剂和鲜乳等加工制成富硒功能性酸乳。L9(33)正交试验表明,最佳工艺条件为:富硒发酵剂接种量9%,加糖量8%,温度41℃,发酵时间5h。该酸乳硒含量达0.45μg/ml,转化硒为0.4157μg/ml,转化率为92.43%。与普通乳酸菌发酵酸乳相比,硒含量提高了约450倍。

Abstract: In this paper, the technology of Se centent of the yoghourt in Se-enriched and activated Lactobacillus was studied. As a result L9(33) orthogonal test indicated that the optimum conditions of technology were confirmed: inoculation rate 9%, 8% sugar added, fermenting temperature 41℃ and fermenting time 5h. In this yoghourt, the content of Se reaches 0.45μg/ml and the content of translating Se is 0.4157μg/ml with translating rate 92.43%. It is about 450 times higher than the content of Se in common yoghourt.
