Summary
This 2024 applied sciences study examined how packaging material selection—particularly novel biodegradable films enriched with natural plant extracts—influences the preservation of health-related bioactive compounds in frozen raspberries across three production systems. The research quantified changes in polyphenols, anthocyanins, and antioxidant activity over 12 months of frozen storage, suggesting that packaging type and natural additives may play a modulating role in nutrient retention during post-harvest storage. The findings contribute evidence to support selection of packaging solutions that better preserve nutritional quality in frozen berry products.
UK applicability
Findings are relevant to UK horticulture and berry production, where frozen storage and export are economically significant; however, applicability depends on whether the study conditions (temperature regime, storage duration) reflect UK cold-chain practices and on whether the identified packaging solutions are compatible with UK regulatory frameworks for food contact materials.
Key measures
Polyphenol content, anthocyanin concentration, antioxidant capacity (measured over 12-month frozen storage period)
Outcomes reported
The study measured changes in polyphenols, anthocyanins, and antioxidant capacity in frozen raspberries stored for 12 months across three production systems (conventional, organic, wild-harvested) using different packaging materials, including novel biodegradable films with plant extract additives.
