Abstract:
... Thermal stabilities of lycopene and β-carotene in tomato pulp and pink grapefruit juice were studied at 80, 95 and 110 °C. Lycopene and β-carotene degradations in both products followed to first-order reaction kinetics, but biphasic curves were obtained for β-carotene degradation. Stabilities of both pigments are highly affected by processing temperatures. For example, t₁/₂ values for lycopene deg ...

Abstract:
... Detecting food adulteration has always been an important task for food safety, especially when grapefruit is the adulterant as components in the juice have undesired interactions with many medicines. In this study we employed a handheld Raman device to detect adulteration of orange juices with grapefruit juices. Fresh fruits of orange and grapefruit were purchased from five different sources and f ...

In contrast, observational studies on regular consumption of 100% fruit juice provide conflicting results, with most indicating a neutral impact on BW and body mass index, while others suggest positive or even inverse associations. The lack of agreement may be due to c ...
