Technology reduces losses and extends post-harvest life

The short post-harvest life of the tomato poses challenges to the supply and profitability of the production chain. According to NanoFood, this climacteric fruit continues to ripen after harvest, which accelerates senescence and limits preservation to just a few days at room temperature. The vulnerability to water loss, mechanical damage, and microbial infections can lead to a reduction of up to 40% of the world's production, reinforcing the need for technological solutions that extend shelf life and stabilize quality. Coatings based on biopolymers, strengthened by functional nanomaterials, create a semi-permeable barrier capable of reducing respiration, controlling ethylene production, and decreasing dehydration. Cited studies indicate superior performance of these systems, with delayed ripening, lower mass loss, and maintenance of bioactive compounds. Research conducted by the Nanotec group showed similar results in guavas treated with a Tara gum matrix and nanostructure, a ...
