Abstract

This research is to determine an appropriate equipment for efficiently waxing pummelo. A laboratory – scale waxing machine with adjustable capacity was built. Experiment was conducted with 2 variable factors ( ic. Wax-application method and storage time ) and three investigated parameters ( ie. consumer’s acceptance, weight loss and firmness of pummelo ). Experiment using conventional chemical spray nozzle ( CCSN ), conventional paint nozzle ( CPN ) and hand showed that the wax application was 1.9, 1.6 and 1.6 cc/fruit, respectively. Weight loss of pummelo manually waxed (≅3% ) was greater than that of CPN ( 2.7% ) and that of CCSN ( 2.5% ). Flesh firmness and consumer acceptance are not significantly different amongst the three wax application methods ( Prob. < 0.5 ), but storage time decreased the firmness significantly ( Prob. < 0.5 ). The waxed pummelo could be stored at least 8 weeks at 25oC room temperature.
