| Abstract | ||
| Growth association relationship between yeast as probiotioc organism and lactic acid bacteria in fermented milks for their probiotic functions enrichment was investigated. The survival and growth of yeast and lactic acid bacteria were monitored over 3-weeks storage period. Specific counts, pH and sensory properties were determined to evaluate the possible contribution of yeasts towards the products. The yeast Saccharomyces cerevisiae was able to survive in yoghurt and in the other products containing Lactobacillus acidophilus and/or Bifidobacterium bifidum. Yeast grew well also in milk as a pure culture while its growth was sharply decreased with increasing the storage period. The inclusion of yeast in fermented milk products stimulated growth of both lactic acid bacteria and yeast-maximum counts, exceeding 9.8 and 6.6 log/ml respectively. pH values were slightly increased upon inclusion of yeast with yoghurt starters and conversely they were slightly decreased in the products containing L. acidophi/us and/or B. bifidum. Growth as:..ociation between yeast and lactic acid bacteria contributed much for obtaining fermented milk products with good sensory qualities. | ||
