The study conducted by Nguyen Tat Thanh University and Can Tho University, Vietnam, reviewed recent developments in the use of biopolymer-based packaging to reduce postharvest losses in Vietnam’s tropical fruits and vegetables. With rising international demand, Vietnam faces challenges in maintaining the quality of fresh produce during long-distance transport due to its perishable nature. Traditional plastic packaging contributes to environmental concerns, prompting interest in biodegradable alternatives.
The review focused on biopolymers as sustainable materials for film and coating applications. These materials help preserve moisture, nutrient content, and sensory quality while extending shelf life. The authors discussed the enhanced effectiveness of combining biopolymers with essential oils, plant extracts, or nanoparticles, which can improve mechanical properties and introduce antimicrobial and antioxidant activities.
The study highlighted the successful use of biopolymers in preserving tropical fruits such as banana, mango, and citrus. It also addressed formulation strategies, critical influencing factors, and the need for compliance with international safety regulations. The findings suggest that biopolymer-based packaging holds promise for reducing postharvest losses and promoting environmentally responsible practices in Vietnam’s fruit and vegetable export sector.
