Kinetic deterioration and shelf life in Rose hip pulp during frozen storage
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.

Importancia y propiedades físico química de la Rosa mosqueta (R. canina, R. rubiginosa): una revisión
Consumers increasingly demand products in their diets that not only provide the nutrients required for a healthy life, they are also preferably those that can complement with beneficial health properties. In recent decades it has been recognized rosehip, Rosa and Rosa canina the rubiginosa as fruits contain many nutraceutical properties. This paper reviews the research papers carried the Rosehip from the point of view of their importance of their consumption and their health benefits; describing the chemical, physical and biochemical characteristics such as content of phenolic compounds, fatty acids, linoleic acid, mineral; and other important also from an industrial point of view, such as antioxidants, pigments, among other compounds. According to the information collected, the Rosehip is a source of micronutrients including vitamin C and lycopene, also delivering a good nutritional value; by the above it should be considered a functional food. Although a species that grows wild on forest soils; still less fruit and herb its importance in the consumer must be considered.
