Distilled water served as the control, while chitosan acted as the coating agent. By comparing the effects of different antimicrobial agents (natamycin, gallic acid, cinnamaldehyde, tea polyphenols, and lavender essential oil), we explored the feasibility of using chitosan as a carrier and its potential applications. Among the treatments, the chitosan-lavender essential oil group demonstrated exceptional performance in reducing insect pests, decreasing from 5.4 % in the control group to 1.82 % after 12 months of storage. The chitosan-natamycin group exhibited the best results across all other metrics, reducing AFB1 content from 60.33 μg/kg to 4.95 μg/kg compared to the control group. Additionally, seed germination improved from 52.33 % to 80.33 %, and the insect pest rate was comparable to that of the chitosan-lavender essential oil group at 1.83 %.

Onion bulbs were cultivated and stored in a temperature- and humidity-controlled system for five months, with evaluations conducted at monthly intervals. The results showed that onion peel lightness (<em>L</em>∗) and hue angle (<em>h</em><sup>o</sup>) were lower in large-sized bulbs compared to small-sized bulbs but peel chroma (<em>C</em>∗) was higher in large-sized bulbs.
