Vitamin C, provitamin A carotenoids, and other carotenoids in high-pressurized orange juice during refrigerated storage.
Vitamin C, provitamin A carotenoids, and other carotenoids were measured in freshly squeezed juices from oranges (Citrus sinensis L. var. Valencia late) that were subjected to high-pressure (HP) treatment. Also, the stability of these compounds was studied during refrigerated storage at 4 degrees C. HP treatment is an alternative to heat preservation methods for foods; therefore, it is essentia...
متن کاملStability 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 کاملThe Effects of Thermal and Non-thermal Processing on Vitamin C, Carotenoids, Phenolic Compounds and Total Antioxidant Capacity in Orange Juice
The abundance of fresh drinks based on fruit juices, especially citrus juices, and minimally processed products allow consumers to ingest a wide variety of antioxidants in the diet, such as vitamin C, carotenoids, flavonoids and other phenolic compounds. Pulsed electric fields (PEF) and high hydrostatic pressure (HHP) are emerging technologies in the field of food preservation. They have the po...
متن کاملDetermination of minimum inhibitory concentration of the ethanolic extract of orange peel and the effects on the growth inhibition of Huso huso filet bacteria during refrigerated storage
Using natural extracts, as a source of anti-microbial, to improve the quality of fish is increasing. In this study, the ethanolic extract of orange (Citrus sinensis L.) was used due to having this property. Agar dilution method was employed in order to determine the minimum inhibitory concentration (MIC) of the ethanolic extract of orange peel on Pseudomonas aeruginosa, E. coli and Aeromonas hy...
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...
