Comparative analysis of antioxidant properties and biochemical composition of wild berries: Raspberry, cranberry and blueberry

The use of natural antioxidants is an effective measure for the prevention and comprehensive treatment of chronic diseases. A comparative analysis of the antioxidant properties and chemical composition of three types of wild berries (raspberries, blueberries, and cranberries) has demonstrated their biological value as natural sources of polyphenolic compounds, anthocyanins, and vitamins capable of suppressing oxidative stress. Blueberries leads in anthocyanin concentration (487 mg/100 g), cranberries – in proanthocyanidin levels (418 mg/100 g) and vitamin C (up to 76.8 mg/100 g), and raspberries – in folate content (200 ?g/100 g). Research has revealed that the composition of biologically active compounds depends on the berry variety, its degree of ripeness, and processing methods. Freezing preserves the maximum amount of nutrients and has no significant effect on antioxidant activity; heat treatment significantly reduces the antioxidant content. It should be noted that the body's absorption of most polyphenols is low, but this deficiency is partially offset by the interaction of the components and the high efficiency of the metabolized forms. The data obtained indicate potential for using these berries in the creation of functional and dietary foods and nutraceuticals, and also highlight the need for further research into encapsulation technologies to improve the delivery and availability of antioxidants, as well as a more in-depth understanding of the metabolism of biologically active compounds.
