Abstract
The aim of the present study was to assess the effect of storage period and temperature on the nutritional quality of orange jam during storage for 30 days at 25 °C and 35 °C. For that purpose, special attention was paid to total sugars (TS), hydroxymethylfurfural (HMF), free amino acids (FAA), ascorbic acid (AA) and carotenoids. It was observed that storage conditions of jam led to statistically significant alterations for all monitored parameters. The decrease rates at the end of storage under 25 °C and 35 °C, respectively, were 12.5% and 15% for TS, 50% and 59.5% for FAA, 23.5% and 29% for AA and 3% and 19% for carotenoids ; likewise, the increasing were of 144% and 169% for HMF. The practical implications of this work are that the derived knowledge could be very useful to optimize storage conditions in order to improve the quality of this product.
期刊介绍：
The Journal of Food Science and Technology (JFST) is the official publication of the Association of Food Scientists and Technologists of India (AFSTI). This monthly publishes peer-reviewed research papers and reviews in all branches of science, technology, packaging and engineering of foods and food products. Special emphasis is given to fundamental and applied research findings that have potential for enhancing product quality, extend shelf life of fresh and processed food products and improve process efficiency. Critical reviews on new perspectives in food handling and processing, innovative and emerging technologies and trends and future research in food products and food industry byproducts are also welcome. The journal also publishes book reviews relevant to all aspects of food science, technology and engineering.
