STUDY ON ACCELERATED SHELF-LIFE TESTING OF UHT COW MILK
Real time shelf-life determination of UHT milk can be very time consuming and
expensive. New procedures must be developed to predict or estimate shelf-lifes of a foodÂ product without running a full length storage trial. The aim of this study was to gain aÂ deeper know-ledge concerning the general and accepted way of performing acceleratedÂ storage tests on diary product with oxidation as the delimiting quality failure parameter.Â The best oxidative indicator was the total hexanal content. The measurement method ofÂ hexanal by using GAS Chromatography (GC) together with Q10 predictive method was theÂ procedure for indirect determination of shelf-life of UHT milk. The shelf-life was estimatedÂ to be 217 days when is styored at 25 oC, 81 days at 35 oC and 35 days at 45 oC.
