Stability of Unpasteurized and Refrigerated Orange Juice
The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12C for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for ...
متن کاملStability and sensory shelf life of orange juice pasteurized by continuous ohmic heating.
Electrical heating of food products provides rapid and uniform heating, resulting in less thermal damage to the product. The objective of this research was to examine the effects of ohmic heating on the stability of orange juice with comparison to conventional pasteurization. During storage at 4 degrees C, degradation curves of ascorbic acid followed a linear decrease pattern in both ohmic-heat...
متن کاملShelf-life study of an orange juice-milk based beverage after PEF and thermal processing.
The effect of thermal and pulsed electric field (PEF) processing on the shelf life of an orange juice-milk beverage (OJMB) was studied. The intensities of the treatments were selected to produce similar inactivation of pectin methyl esterase (PME), an enzyme responsible for the jellification and loss of fresh juice cloudiness. Physical properties (pH, degrees Brix, and color), microbial populat...
متن کاملOutbreak of Salmonella serotype Hartford infections associated with unpasteurized orange juice.

متن کاملSeville (sour) orange juice: synephrine content and cardiovascular effects in normotensive adults.
The Seville orange extract Citrus aurantium contains m-synephrine (phenylephrine) and octopamine; it causes cardiac disturbances in animals and is used by humans for weight loss. Juice from the orange (Seville orange juice [SOJ]) is used to "knock out" intestinal cytochrome P450 (CYP) 3A4 in bioavailability studies. The purpose of this study was to determine synephrine and octopamine concentrat...
