<p dir="ltr">This study explores the use of hand warmers to enhance hermetic storage. Hand warmers work similarly to conventional oxygen scavengers by consuming oxygen through oxidation. This research aimed to determine how effective hand warmers are in accelerating oxygen reduction and insect mortality in hermetic storage, hence preserving grain quality. The experiments conducted in hermetic containers showed that hand warmers rapidly reduce oxygen levels, achieving insect-lethal conditions much faster than conventional oxygen absorbers like Oxy-Sorb. Our results show that hand warmers brought oxygen levels down to below 5% within 24-48 h and kept them low for an extended period up to 240 h. This quick oxygen depletion led to high insect mortality, reduced oviposition, and inhibited progeny development. Additionally, hand warmers did not negatively impact seed moisture content or germination rates, demonstrating their effectiveness in maintaining grain quality during storage.</p>
