Abstract

This investigation was carried out on green garlic cv. Balady, which is appropriate for exporting at immature stages during the seasons of 2024 and 2025. The purpose of this investigation was to study the effect of smart packaging treatments (Smart-film: Life-Span packaging, Lifepack®, and smart packaging modified) and modified atmosphere package (MAP) (active MAP at 3%O2+5%CO2 and passive MAP), as well as unpacking as a control. To maintain the quality and storability of green garlic for 20 days of cold storage at 0°C and 90-95% relative humidity. The results showed that all packaging material treatments outperformed the unpacked control regarding preserving green garlic quality and extending its storage time. Furthermore, active MAP at 3%O2+5%CO2 gave the best treatment, which reduced weight loss, maintaining a significantly higher L* value, pyruvic acid and titratable acidity (TA) content. Additionally, it maintained an excellent appearance for twenty days of storage without any exterior leaf development or discoloration, whereas the smart packaging modified gave a good appearance during the same period.
