| English abstract | The present experiment was aimed at determining the respiratory rate and ethylene production of fresh cut radish and whole radish during cold storage. The rates were evaluated during the first 4 hours after processing and daily, during 10 days at 5°C (± 1°C) and 90% (± 5%) RH. Radishes not processed presented lower respiratory rate (40.61mL CO2 kg-1 h-1) if compared to shredded radishes (93.90mL CO2 kg-1 h-1) 4 hours after processing. Whole and fresh cut radishes showed the highest respiratory rate in the 2nd day of storage with 99.27 and 170.32mL CO2 kg-1 h-1, respectively. On the 10th day of storage, fresh cut radishes showed respiratory rate 149% higher than whole radishes. The minimal processing operations, mainly the cut, enhanced the respiratory rate |
| Portuguese abstract | O presente experimento visou a determinar a taxa respiratória e a produção de etileno de raízes de rabanete minimamente processadas em comparação ao produto não-processado, durante armazenamento refrigerado. As taxas foram determinadas durante as 4 primeiras horas após o processamento e diariamente, por 10 dias de armazenamento a 5°C (± 1°C) e 90% (± 5%) UR. Raízes de rabanete inteiras apresentaram taxa respiratória de 40,61mL CO2 kg-1 h-1, enquanto que as raízes em retalhos apresentaram até 93,90mL CO2 kg-1 h-1 após 4 horas do processamento. As raízes de rabanete inteiras e as minimamente processadas apresentaram pico respiratório no 2° dia de armazenamento, com 99,27 e 170,32mL CO2 kg-1 h-1, respectivamente. No 10° dia de armazenamento, as raízes de rabanete minimamente processadas apresentaram taxa de respiração 149% superior à verificada nas raízes inteiras. As operações de processamento mínimo, principalmente o corte, elevaram a taxa respiratória das raízes de rabanete |
