Sustainable Packaging Solutions for Bulk Export of Cumin Seeds to Global Spice Markets

Abstract

The objective of this study was to determine the most effective bulk packaging materials for cumin seeds, ensuring the preservation of quality during export processes. Preserving the quality of spices is of paramount importance, particularly with regard to utilizing effective oxygen and gas barriers to maintain aroma. To address these concerns, multiwall paper bags were tested for their efficacy in prolonging the shelf life of cumin seeds. A selection of four packaging materials, chosen based on sustainability criteria, was exposed to accelerated aging conditions set at 38±1°C and 90±2% relative humidity over a period of six months, and shelf life was evaluated. Export packaging specifications were developed using paper-based sustainable packaging materials to ensure compliance with transport requirements. The results demonstrated that multiwall paper bags lined with aluminium foil successfully inhibited moisture and oxygen ingress, thereby preserving the quality of the product and extending its shelf life. Although fossil-based packaging is better suited for long-distance transport, multilayer paper bags offer unique advantages. They meet essential requirements and are inherently sustainable, allowing producers to support sustainability and a circular economy.
