Abstract
Rose hip is of great interest among food manufacturers and consumers because it contains compounds that give it a high antioxidant capacity. To determine the effect of the frozen storage process over the vitamin C content, total phenols, antioxidant capacity, linolenic acid, linoleic acid, and other properties, rose hip pulp was stored at -5°C, -10°C, -15°C and -20°C. Also, the temperature of -18°C was considered in order to verify differences between the predicted and experimental rates at this commercial storage condition. The kinetics were modeled using the Weibull model, and their rates were correlated with the temperature using the log-logistic model. Results showed that vitamin C, total phenols content, antioxidant content, and linoleic decreased while frozen. The degradation of vitamin C in rose hip pulp during frozen storage was lower than the degradation rate of the total phenols and the antioxidant capacity, respectively. Shelf life of frozen rose hip pulp was established to be 329.8 days at -18°C.
