Abstract
The purpose of food packaging is undergoing significant transformations to meet the
evolving demands of the market. Factors such as food safety, consumer preference for
healthier options, the need for high-quality products, extended shelf life, convenience,
transparent packaging, and sustainable materials have led to the emergence of
innovative packaging technologies, including active packaging. This study focused on
the development of an active packaging system using chitosan, known for its effective
barrier properties against moisture and gas permeation. Firstly, stable microemulsions
containing clove oil were formulated, with an average particle size of 142.2±2 µm, and
characterized for thermal stability and pH changes. Secondly, these microemulsions
were incorporated into chitosan matrices to create the chitosan-based active packaging
system. To address the perishability and post-harvest losses of tomatoes, the developed
active packaging system was applied to tomatoes through various treatments involving
active coatings and sprays.
