The effects of gibberellic acid (GA3), at various concentrations and application times, on the susceptibility of the rind to injury, the incidence of physiological disorders, and the storage life of Washington Navel oranges were examined over three seasons. Susceptibility of the rind to injury, the incidence of water spot, puffing and creasing, and green mould wastage in stored fruit were reduced by GA3 treatment. Resistance of the rind to puncture increased with increasing GA3 concentration. Early May sprays were more effective than early June sprays in increasing. the resistance of the rind to puncture and decreasing the incidence of puffing and creasing. Split applications were no more effective than single applications at the combined concentrations. There were no undesirable effects on internal fruit quality. Although colour development was delayed by GA3 treatment, with late harvest colour development progressed to a commercially acceptable level while internal fruit quality was still satisfactory.

<p>‘Maha Chanok’<strong> </strong>mango is an economic fruit crop widely cultivated commercially throughout Thailand. By nature, mango fruit has a rather limited storage life after harvest. 1-methylcyclopropene (1-MCP) has been accepted as a commercial substance to improve several fruit qualities. The objective of this research was to study the effects of 1-MCP on the external postharvest qualities and storage life on the ‘Maha Chanok’ mango fruit. The experiment was laid out in a Completely Randomized Design with three replicates, ten fruits per replicate. Mango fruit was fumigated with 1-MCP at three concentrations (1000, 1250, or 1500 nl l<sup>-1</sup>) and three fumigation periods (12, 18, or 24 h), compared with the control fruit. After treating, all treatments were stored under ambient temperature (27 °C, 80%R.H.). The following determinations were made every two days for assessment of fruit weight loss, firmness, chlorophyll content, decay incidence, and storage life. The results showed that fruit treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 24 h had the maximal fruit firmness. For chlorophyll content, the results showed that fruit-treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h could effectively retain the highest chlorophyll contents. Furthermore, both the lowest fruit decay and the longest storage life of 12 days were achieved from the fruit treated with 1000 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h.</p>

Brine Injection

This study was undertaken to determine the impact of the moisture enhancement process on the bacterial contamination and storage life of vacuum-packaged pork loins. Bone-in and boneless pork loins injected with brine (sodium chloride, sodium phosphate, lemon juice) were obtained from a commercial processing facility and stored for 5 weeks in vacuum packaging at 2 and 5°C. At weekly intervals, samples were excised to determine numbers of spoilage bacteria and pathogens. The loins were subjectively evaluated by a sensory panel to quantify appearance and odor acceptability. Moisture-enhanced loins were initially contaminated with a population of psychrotrophic bacteria that was approximately 2 log units higher than that for noninjected boneless loins. This difference was largely due to contamination by larger numbers of pseudomonads in the brine-injected loins. There were no significant differences in the initial numbers of lactic acid bacteria, Enterobacteriaceae, or Brochothrix thermosphacta. Similar trends in spoilage bacterial populations were observed for moisture-enhanced loins with bones, but Enterobacteriaceae counts were also found to be approximately 1 log unit higher for the injected product. Brine-injected loins generally had larger bacterial numbers at each storage time, but there were no consistent injection treatment effects on bacterial growth. Brine injection did not affect color or odor deterioration, and the storage life for vacuum-packaged loins was the same as that for noninjected controls. The incidence of Listeria monocytogenes was 21% for control loins and 27% for moisture-enhanced loins. Although the brine injection process resulted in an increase in bacterial contamination, there was no evidence that this contamination would affect the storage life of vacuum-packaged loins, and further research is necessary to determine the significance of the increased incidence of L. monocytogenes.

Limited shelf life of green mussel restricts its accessibility to wider markets. The study assessed the potential of using organic acids (lactic and citric acids) in enhancing the quality and storage life of chilled mussel. Pretreatments included: 2% lactic acid (LA) and 2% citric acid (CA). Results from sensory analysis concluded that lactic acid (LA) pretreatment had 15 days of acceptability compared to the untreated sample. It had also lower the volatile basic nitrogen (TVB-N), trimethylamine nitrogen (TMA-N), psychrophilic and lactic acid bacteria count of the sample during the storage. The weight loss of the citric acid pretreated sample was higher compared to the lactic acid pretreated mussel. Results from quality assessment indicated that pretreatment using lactic acid can be used to improve the storage life of chilled green mussel for 15 days compared 6 days of untreated samples.
