Summary

Preferential breakdown of beta-casein was recorded when ewe milk inoculated with Pseudomonas fluorescens INIA 724 was held for 6 days at 4 (24.12%) or 8 deg C (29.07%). Alpha-casein was more rapidly degraded at 4 (17.47%) and 8 deg C (23.33%) than beta-casein in control milk not inoculated with P. fluorescens. The area of a peak with a retention time corresponding to that of glycomacropeptide showed after 4 days a 15.6-fold increase at 4 deg C and a 39.3-fold increase at 8 deg C. Coagulation times of milk held for 4 days at refrigeration temperatures were shorter, and coagulum firmness higher, than those of the respective control milk.
