Armazenamento refrigerado sob atmosfera modificada de pedúnculos de cajueiro-an?o-precoce dos clones CCP-76, end-157, end-183 e end-189

摘要

Apples or false fruits from early dwarf cashew clones CCP-76, END-157, END-183 and END-189 were stored for 25 days under refrigeration associated to modified atmosphere with the aim of evaluating the effect of the conditions presently adopted (5oC and 85-90% RH) for conservation, storage and commercialization of fresh cashew apples. The cashew apples were evaluated every 5 days for the following characteristics: weight loss, pulp firmness, color (anthocyannins), acidity, pH, soluble solids, vitamin C and phenolic contents. With the use of refrigeration and modified atmosphere it was possible to attain postharvest storage life of 10 days for clone END 189, 15 days for clone END 157 and up to 25 days for clones CCP 76 and END 183. It was found that 5oC was not an adequate temperature to store cashew apples with deeper color (END 157 and END 189) than the control (CCP 76), as it caused loss of anthocyannins starting from the 10th day of storage. Weight loss was significantly reduced by the use of modified atmosphere, favoring the appearance of the cashew apples for market, independently of the clone.
