| Abstract |
The objective of the present study was to improve quality of Ras cheese made from pasteurized milk and evaluate possibility of introducing Bifidobacteria in the cheese to be suitable delivery vehicle for probiotic bacteria.
The applied treatments included using yoghurt culture (YC) in the control cheese, whereas L.rhamnosus (R) with YC (YCR), bifidobacteria (B) with YCR (YCRB) and EPS-producing culture (YE) with RB (YERB) were applied in the other treatments and their effects were followed during 90 days of ripening at 15OC.
The attained results revealed that. the maximum improvement was achieved when YERB was used since the resultant 90 days old cheese had the maximum values compared to the other treatments for moisture, fat/DM, SN/TN, Shilovich and formol ripening indices, TVFA, total bacterial count and counts of Streptococci and Lactobacilli with reasonable counts of bifidobacteria. Their count (log cfu/g) was 8.45 in the fresh YERB cheese and increased to 8.86 in the corresponding 90 days old cheese. The hardness of YERB cheese was less with improving most of the other rheological properties. The Sensory evaluation showed that the prementioned cheese with YERB ranked the maximum scores for flavour, body & texture and the general appearance with an over all scores of 90.2 out of l00 points.
