Coating based on breadfruit starch (Artocarpus altilis) for fruit conservation: influence of glycerol, sorbitol, and mannitol as plasticizers

Abstract Polysaccharide-based coatings are an alternative to synthetic coatings for fruit conservation. In this study, we aim to evaluate the physical and chemical characteristics of breadfruit starch for coating using glycerol, sorbitol, and mannitol as plasticizers.

Sumario:Abstract Polysaccharide-based coatings are an alternative to synthetic coatings for fruit conservation. In this study, we aim to evaluate the physical and chemical characteristics of breadfruit starch for coating using glycerol, sorbitol, and mannitol as plasticizers. We applied coatings composed of 7% starch and 2% plasticizers to cherry tomatoes, and evaluated the storage during 12 days at a temperature of 18 °C. The breadfruit starch had an amylose content of 27.17%, granular size of 0.85-0.87, a gelatinization temperature of 75.10 °C, characteristics of standard starch type B and low syneresis. Coatings composed of glycerol and sorbitol showed a reduction in mass loss and delayed ripening. Glycerol and sorbitol are recommended for preparing coatings based on breadfruit starch for post-harvest storage of tomatoes.
