Özet

In this study, synbiotic kefir types were produced by the addition of probiotic bacteria and prebiotics to cow and goat milk. Commercial DVS kefir cultures, Lactobacillus acidophilus LA-5, Bifidobacterium bifidum BB-11 as probiotic cultures and inulin as prebiotic for the production of the kefir samples. The effect of the different probiotics and prebiotic on some characteristics of kefir made from cow and goat milk was investigated. Titratable acidity, tyrosine content, volatile components and sensory properties of samples were examined on the 1st, 7th, 14th and 21st day of storage. According to the results, titratable acidity and tyrosine amount in kefir increased during the storage period. There was a gradual increase in the acetaldehyde value of kefir made from cow milk during the storage period, whereas there were no regular changes obtained in the kefir produced from goat milk. However, the diacetyl content varied in all the synbiotic products during storage. The total acceptability results showed that the synbiotic kefir made from cow milk was more preferred to the one made from goat milk.
