the freeze-drying process. Continued viability of rehydrated cells during incubation at 37 C for 3 hours was dependent on the composition of the suspending medium. The number of viable organisms decreased greatly when suspended and incubated in water. Several salts were effective in maintaining higher viable cell counts. Maximum recovery of viable cells of one dried preparation rehydrated in ma...
متن کاملStorage Stability of Orange Juice Concentrate Packaged Aseptically
Orange juice concentrates were packaged aseptically by a “Dole” aseptic canning machine using 6 oz metal cans. The final juice products (ll”, 34’, 44’, 58” Brix) were stored between -18” and 36°C and tested periodically for nonenzymatic browning, ascorbic acid destruction, furfural and sensory changes. Nonenzymatic browning, the main deterioration phenomena in these products, was satisfactorily...
متن کاملCharacterisation of frozen orange juice by ultrasound and wavelet analysis
Ultrasound technology was used to analyse the freezing behaviour of orange juice. The ultrasonic properties of orange juice, specifically velocity and attenuation coefficient, were characterised as the temperature was decreased from 20 to −50 ◦C. The results were compared with NMR free induction decay data and correlated with the amount of unfrozen water present in the frozen sample. The veloci...

متن کاملEffect of freezing, irradiation, and frozen storage on survival of Salmonella in concentrated orange juice.
Six strains of Salmonella (Anatum F4317, Dublin 15480, Enteritidis 13076, Enteritidis WY15159, Stanley H0588, and Typhimurium 14028) were individually inoculated into orange juice concentrate (OJC) and frozen to -20 degrees C. The frozen samples were treated with 0 (nonirradiated), 0.5, 1.0, or 2.0 kGy of gamma radiation and held frozen for 1 h, and the surviving bacterial population was assess...
