AVALIAÇÃO FÍSICO-QUÍMICA E MICROBIOLÓGICA DE GOIABA (Psidium guajava) REVESTIDA COM COBERTURA COMESTÍVEL À BASE DE O-CARBOXIMETILQUITOSANA E ÓLEO ESSENCIAL DE ORÉGANO (Origanum vulgare)

Abstract: A goiaba (Psidium guajava) é um fruto tropical climatérico, caracterizado por altas taxas de respiração e vida útil reduzida após a colheita. A senescência do fruto é rápida (ocorre em até quatro dias) e ocasiona perda de atributos de qualidade física, sensorial e nutricional, além de comprometer o prazo de transporte e armazenamento. Dessa forma, o desenvolvimento de técnicas que aumentem sua vida pós-colheita é uma necessidade. Os objetivos deste trabalho foram o recobrimento de goiabas com coberturas comest… Show more

“…Uncoated guavas and coated guavas based on cassava starch and chitosan showed pH values between 3.85 and 4.10, with small significant differences between treatments over storage time (de Aquino et al, 2015), as occurred in the present study. Coatings based on O-carboxymethyl chitosan and oregano EO in guavas showed greater pH variations (between 4.1 and 4.7) (Tavares et al, 2018).…”

“…Attributes such as color, aroma, and flavor are influenced by the acidity and pH; for instance, decreasing the pH can prevent the oxidative darkening of the fruit's tissues (Tavares et al, 2018).…”
