| Passion fruit juice, pure and sucrose sweetened (1:1, w:v), was frozen and stored for 8 months in freezers. The effect of storage time and sucrose addition on physicochemical properties of the juices was evaluated, in the fresh juice, and then every two months in the stored samples. Concentration of soluble solids, organic acids, total and reducing sugars and ascorbic acid, as well as pH were not affected by storage time. Initially sucrose addition modified the juice color, but not during storage time, while the natural juice became more yellow during storage. β -carotene content decreased as a function of storage time, 51.3 % in the pure juice and 29.7 % in the sweetened juice. |

| The aim of this study was to evaluate and compare the percentage content of fatty acids (FA) of 54 rainbow trout fresh and frozen fillets. Frozen fillets were stored at -15ºC for 45 and 90 days. Saturated (SFA), monounsaturated (MUFA), polyunsaturated (PUFA), omega-6 (n-6) and omega-3 (n-3) fatty acids were determined by gas chromatograph coupled to mass spectrometry. The results indicated that during frozen storage, SFA and MUFA content increased by 32.63 and 9.25%, respectively, while PUFA content decreased by 25.3%, n-6 by 12.4% and n-3 by 32.55%. These changes were more significant (P ≤ 0.05) during the first 45 d of storage. It was concluded that the frozen storage had a negative impact on meat quality of rainbow trout due to the reduction of PUFA,... |
