Características físicas e químicas do maracujá-amarelo tratado com cera e armazenado em condição ambiente

Abstract

This study aimed to assess the main physical and chemical characteristics of yellow passion fruits ( Passiflora edulis Sims. f. flavicarpa), treated with wax and stored at room temperature for a period of twelve days. The following treatments were applied on ripe fruits: 1- Wax at 0% (only distilled water); 2- wax at 50% + Distilled water at 50% ; 3- Wax at 100% (undiluted). After treatment, the fruits were placed in plastic boxes (55x35x30 cm), and stored in natural environment (20+ 10 RH). Cumulative mass loss and time evaluation (%), LD/TD relationship, peel thickness (mm), juice yield, peel and seed ( %), peel and seed relationship, total soluble solids (Brix) and total acidity (citric acid %) were performed every three days (0; 3; 6; 9; 12). Completely randomized design was used, in a factorial diagram 3x5 (wax x storage time), with four repetitions in a four fruit plot. The use of wax benefits fruit quality, reducing mass loss, without affecting yield and the fruit's juice composition. (English) [ABSTRACT FROM AUTHOR]
