| heal.abstract | The extent of proteolysis and lipolysis in full fat (cheesemilk 6.1% fat) and low fat (cheesemilk 2.1% fat) Kefalograviera cheeses made from non-refrigerated and refrigerated 3-4 degreesC, 4 d) ewe's milk was evaluated. Nitrogen soluble in 5% phosphotungstic acid as % of total nitrogen (PTA-SN) and acid degree value (meq/100 g fat) was determined in cheese samples of 40-, 90- and 180-d-old cheese. In several cases, low fat cheeses exhibited statistically lower (p<0.05) values of PTA-SN than the respective full fat ones. Acid degree values did not differ (p > 0.05) among cheeses. In 90- old cheeses (matured cheeses) urea-PAGE, RP-HPLC analysis (profiles) of water-soluble extracts, and determination of individual free fatty acids by GC were performed. It appeared that in low fat cheeses a) there was a lower degradation of alpha (s1)- and beta- caseins, b) the sum of individual free fatty acids was lower, while this sum per cheese fat was higher, and c) several peaks of the later part of the RP-HPLC trace were higher than that in full fat cheeses. Cheeses from non-refrigerated milk, full fat and low fat, showed no significant differences in the parameters examined as compared to the respective cheeses from refrigerated milk. | en |
