Qualidade e bioquímica de parede celular de sapoti [Manilkara sapota (L.) Von Royen] submetido ao 1-metilciclopropeno

Abstract

The brazilian market of exotic fruits has shown good perspectives lately* However, many species, although their high market potential, are still low commercialized Ámong those species, sapodilla is highly acceptable by the market consumer, because your appreciable taste. The brazilian sapodilla ore hards are still deprived of postharvest teehnologies, so there are many damages on that stage. With aim to generate technology for quality maintenance and to elongate the postharvest life time of sapodilla, the purpose on this work was to evaluate the effect of 1-metilciclopropeno(1-MCP), as a blocker of èthylèneaetion, on many attributes off rait quality, The fruits* origined from Jaguaruana, Ceará state, Brazil, were treated with1-MCP(0, 100,200,300e 400nLX*1),for 12 hours, storage under modified atmosphere, temperature 25 è 2°C* relative humidity 70 á 5% during 23 days, The frühs ürider treatments had more six days of post harvest life time and the best1-MCP doses were between200 and 400nL-L"1.Thetreatment with 300nL.L"1retardedthe lossof fruit firmnêssès, duê to its inhibitory aetion on thê pêctin mêthylèstêrasê, polygalacturonasean dp-galactosidase enzymes acitivity, resultingin less pectin solubilization and less cellulose, hemicellulose, polyuronideos and neutral sugars degradation.
