Abstract
Three types of film lid (OPP/LLDPE, PET and LDPE) were used to seal rigid trays containing fresh-cut mangosteen to examine the influence of the films on the gas composition of the headspace and the quality of the product during storage. LDPE film, which has the highest OTR and CTR (2,795 and 10,500 cm3/m2 day, respectively) (analyzed by the Department of Science Service), showed the highest O 2 , C 2 H 4 , ethanol and acetaldehyde accumulation and lowest residual CO 2 in the package. Furthermore, firmness and weight losses were higher than those of OPP/LLDPE and PET films. Film type did not affect the microbial growth of fresh-cut mangosteen during storage. Overall visual quality (OVQ) was influenced by type of films. Samples packed in PP trays sealed with OPP/ LLDPE and PET films maintained higher sensory quality than those packaged in LDPE film under the same storage conditions.
