| Summary: | The fruit and vegetable markets create challenges regarding the storage of perishable foods and exhibits the need to identify and evaluate the proper conservation treatments for products on the shelf, reducing to the minimum proportion the losses after harvest and maximizing its shelf life. The objective of this study is to evaluate the behavior of the coatings on Badea (Passiflora Quadrangularis) with wax and Cassava (Manihot Esculenta) using food grade paraffin, determining the physiological changes that can alter the quality of the product under controlled storage conditions. For Badea, Passiflora quadrangularis, after 12 days of storage, an average weight loss of 18.63 gr was registered, with the commercially available coatings (KMnO4 packed in perforated PE bags with: a loss of 1.11 g/100g, a weight of 1307.11 ± 177.00 g, juice yield and aryl: 15.01 ± 1.86 %, y pulpa 69.29 ± 4.82 %, average pH value: 3.91 ± 0.12, soluble solids of 10.78, acidity of 0.80 ± 0.10 g/100g. With Cassava, the registered weight was 565.40 ± 323.50 g, length: 23.58 cm ± 6.18, and diameter of 60.53 mm. The applied treatment was paraffin presenting a 76.68% ± 7.55 yield and a 16.20% ± 1.2 humidity loss. The breathing rate of the Cassava without paraffin treatment, was 100.57 mg CO2 8°C. The conservation treatments are effective, keeping the quality of the products protected, and controlling the loss of weight by transpiration. /Kg*h and with paraffin was 116.82 mg CO2/Kg*h, at8°C. The conservation treatments are effective, keeping the quality of the products protected, and controlling the loss of weight by transpiration.
