利用传统酸牛乳酒(Kefir)的发酵剂—开菲尔粒(Kefir Grains)制作的发酵剂,对榛子乳与牛乳的混合原料进行发酵,采用L16(45)正交试验设计筛选制备开菲尔榛子乳的最佳发酵条件。结果表明:当榛子乳与鲜牛乳混合比例8∶2,接种量为3%,发酵温度25℃,加糖量10%,发酵时间14 h时,所得的产品的酸度为83°T,乙醇体积分数为0.26%,风味柔和,口感独特。 相似文献

研究开菲尔粒在榛子乳中的发酵特性,为研制开菲尔粒榛子乳奠定基础。将驯化好的开菲尔粒接种到原料榛子乳培养基中,研究开菲尔粒在不同榛子乳培养基浓度、开菲尔粒接种量、乳糖量、发酵时间及温度下的发酵特性。结果显示:将驯化好的开菲尔粒按5%的接种量接种到榛子乳(1︰7,2%的乳糖)培养基中,23℃恒温发酵18 h,发酵效果良好。 相似文献

Four Lactobacilli were isolated from both commercial cowmilk yoghurt ("Fan" yoghurt) and "wara", a West African soft cheese. They were identified
as Lactobacillus acidophilus ("Fan" yoghurt), L. plantarum, L. brevis and unidentified Lactobacillus spp. ("wara"). L. acidophilus and L. plantarum were chosen as starter organisms for the production of a yoghurt-like product from cowpea milk. There was a decrease in the
final pH and an increase in the titratable acidity of the cowpea milk samples at the end of the fermentation period. The crude
protein, total ash, calcium, potassium and phosphorus values increased in the fermented cowpea milk, while a decrease was
obtained for the lipid, moisture and crude fibre contents. A decreasing trend was noted in the phytic acid and trypsin inhibitor
of the cowpea flour when processed into milk, followed by a further reduction at the end of fermentation. Consumer acceptability
of the cowpea yoghurt varied, with preference being given to the banana and strawberry flavoured samples.
