Probiotics defined as additional microorganisms were added to goat milk powder, which not only improves the intestinal flora balance but also promotes human and animal health. The objectives of this study were to improve and guarantee high probiotics viable count and accordance with consumer's acceptance.
The reading selected the number of colony between 30 and 300, then calculated the viable count per gram of goat milk tablet (cfu/g). The items of sensory evaluation included: appearance, flavour, colour, texture and taste. The score test was composed of 5 trained assessors, scored combination of different formulations (full marks of 100 points) and recorded the results.
Analysis of the results showed that sucrose, inulin and mannitol were selected as the main effective parameters on both viable count and sensory evaluation. Furthermore optimization of the formulation of probiotic goat milk tablets was to maximise the probiotics viable count to achieve 9.5·108 cfu/g and its scores of sensory evaluation to get 94 points.
Future probiotics products will be combined with a variety of probiotics, which can display their respective advantages and characteristics. Thus the products will not only be in accordance with the requirements of human health and trend of social development, but also will quickly become a favorite among consumers.
益生菌作为额外添加的微生物被添加到羊奶粉中，其不仅能改善肠道菌群平衡，还能促进人和动物的健康。本研究的目的是提高并保证益生菌的高活菌数，同时符合消费者的接受度。
选取菌落数在30至300之间的样本，然后计算每克羊奶奶片的活菌数（cfu/g）。感官评价项目包括：外观、风味、颜色、质地和口感。评分测试由5名经过培训的评估员组成，对不同配方进行评分（满分100分）并记录结果。
结果分析表明，蔗糖、菊粉和甘露醇是对活菌数和感官评价都有主要影响的有效参数。此外，益生菌羊奶奶片配方的优化是使益生菌活菌数最大化，达到9.5·108 cfu/g，其感官评价得分达到94分。
未来的益生菌产品将与多种益生菌组合，能够发挥各自的优势和特点。这样的产品不仅符合人类健康需求和社会发展趋势，还将迅速成为消费者的宠儿。
