In
this study, cow and buffalo milk with different fat contents were used for the
production of kefir drinks with kefir grain or kefir culture, and the protein
and tyrosine contents of kefir drinks were determined during 21 days of storage
at 4°C. The protein content of samples decreased during storage (P<0.05). Protein
contents of kefir samples ranged from 3.44 to 4.80% (P<0.05) at the
beginning and from 3.31 to 4.71% at the last day of storage. Tyrosine content
of kefir samples increased for the first 14 days of storage, and it decreased
at the end of storage except for the kefir produced with cow milk (P<0.05). Tyrosine
contents of samples produced with starter culture were higher than those with
kefir grains, and the use of cow milk had a significant effect on the tyrosine
content of kefir samples (P<0.05). At the end of storage, the highest
tyrosine content (15.80 µg/g) was determined in kefir from cow milk with a 0.5%
fat content and starter culture, and the lowest (8.04 µg/g) was determined in kefir
from buffalo milk with a 3% fat content and kefir grain (P<0.05).
