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.

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. Onion peel color and hue angles were lower in the extra-large bulb than in the small bulb.
