Abstract
Edible active packaging is an innovative solution that extends the shelf life of products, protect it from contamination, and prevent oxidation, without contributing to additional packaging waste. Here this study explores the potential of utilizing cascara extract, a coffee by-product rich in polyphenols and polysaccharides, as a sustainable material for preserving roasted hazelnuts. Gelatin and glycerol are investigated as additives to enhance film properties. Optimal formulations were exhibited promising barrier performance, antioxidant activity and low surface energy. Based on Response Surface Methodology (RSM), the formulation consisted of 5.1 % w/v gelatin as the primary film-forming agent, 89.2 % w/v cascara extract as an active component, 5.7 % w/v glycerol as a plasticizer, showed the highest oxygen barrier property. Accelerated shelf-life testing (ASLT) at 35 and 45 °C indicated selected cascara coating potentially doubling hazelnut shelf life. The cascara edible coating had a brown film appearance which can be acceptable for dark coloured food products in future application. Despite deviations in color, cascara offers potential for sustainable packaging, opening avenues for innovative solutions.
期刊介绍:
Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
