Abstract:   (13491 Views)
The influence of stabilizers on the stability of UHT(Ultra High Temperature) dairy cream was studied. Dairy cream, at 30% fat, with and without stabilizers, was ultra-high temperature sterilized (1400C/4s) with 2-stage homogenization pressure at 150/20 bar. The stabilizers added to the cream were carrageenan (0.01%w/w & 0.03% w/w), trisodium citrate(0.1% w/w & 0.2% w/w), and a commercial stabilizer (0.2% w/w). UHT cream samples were stored at 20-25 0C for 8 weeks. The Stability of cream was weekly determined by centrifugation of samples at 180 * g (1058 rpm) for 5 min., and by measuring the volume of the serum phase separeted during centrifugation. As a result, stabilizer addition led to a significant reduction(p<0.05)in serum separation during storage time. In addition, increasing the amount of stabilizer significantly correlated with the stability of the UHT cream.
