Summary: | In the present research it was determined the cooling time of yellow Bell pepper 'Zarco HS' submitted to forced air cooling, using different types of packaging, as well its postharvest conservation under refrigeration at 5,1 ± 0,2°C and 98,6 ± 0,3% RH during a period of 30 days under. The temperature was measured by thermocouples in the chamber, the evaporator, fruit and packs for a total of 48 thermocouples. The analysis of mass loss, humidity content, and firmness index were realized. It was possible to conclude that the forced air cooling process it's a feasible technology for postharvest conservation of yellow bell pepper 'Zarco HS' reducing the temperature of 7/8 cooling time to the maximum of 56 minutes. Key words: Capsicum annum L., temperature, conservation, postharvest. No presente trabalho, determinou-se o tempo de resfriamento de pimentao amarelo 'Zarco HS' submetido ao resfriamento rapido com ar forcado, usando diferentes tipos de embalagens, bem como sua conservacao pos-colheita por um periodo de 30 dias sob refrigeracao a 5,1 ± 0,2°C e UR de 98,6 ± 0,3%. A temperatura foi medida atraves de termopares na camara, no evaporador, nos frutos e nas embalagens, num total de 48 termopares. Foram realizadas as analises: perda de massa, teor de umidade e indice de firmeza. O trabalho permitiu concluir que o resfriamento rapido com ar forcado mostrou-se adequado quando aplicado como uma tecnologia de conservacao pos-colheita para pimentao amarelo 'Zarco HS', com uma reducao da temperatura de 7/8 do tempo de resfriamento em no maximo 56 minutos. Palavras-chave: Capsicum annum L., temperatura, conservacao, pos-colheita. |
