متن کاملDiacetyl Test as a Quality Control Tool in Processing Frozen Concentrated Orange Juice
One subjective and two objective methods were used to determine the color of reconsti tuted frozen concentrated orange juice. The USDA color scores for 21 samples ranged from 32 to 37 points when this subjective method was used. Two objective methods were used: (a) the Hunter Color and Color Difference Meter to ob tain tristimulus color values and (b) the Bausch and Lomb Spectronic 505 recordin...
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...
متن کاملEffect of varied storage temperatures on microorganisms in frozen concentrated orange juice.
Extensive studies on the effects of conditions that may be encountered in commercial handling on quality of frozen foods have been under way at the Western Utilization Research and Development Division of the U. S. Department of Agriculture during recent years. The commodities investigated have included frozen concentrated orange juice. Chemical and physical changes in this commodity under vari...
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...
