Physico-Chemical Characteristics of Rosa Canina L. Seeds and Determining Their Potential Use

This study investigated the physico-chemical properties of Rosa canina L. seeds, revealing their potential as a high-value ingredient for health products. The seeds were found to have significant nutritional content, including carbohydrates (79.2 g/100 g), soluble dietary fiber (71.6 g/100 g), protein (7.67 g/100 g), and fats (6.23 g/100 g), with linoleic acid (53.19%) being the most dominant fatty acid. They also contained high levels of calcium (3851 mg/kg), potassium (2732 mg/kg), phosphorus (991 mg/kg), and vitamin C (1783 μg/g). The seeds exhibited antioxidant properties, with phenolic compounds (2633 μg/g) and carotenoids (3.13 μg/g) contributing to this activity, as measured by FRAP (191 μmol TE/g) and DPPH (229 μmol TE/g) methods. These findings suggest that rosehip seeds, a by-product of the food processing industry, could be utilized in nutraceuticals, pharmaceuticals, and cosmeceuticals.
