| Abstract: | The physical and chemical changes of guava were measured after being hydro-cooled (cooling time of 1/8, 1/4 and 1/2) and stored at 5,10 and 15 C for 6 weeks. The results showed that hydro-cooled fruit were significantly better in quality than the control. Hydro-cooled fruit showed less changes of colour (from green to yellow), were brighter, had lower incident of browning and less weight loss. Soluble solids concentration and pH value of fruits were maintained. The different levels of cooling time show significant effects on browning scores of the fruits. Cooling time at 1/8 showed lower incidence of chilling injuries compared to 1/2 cooling time. Chilling injuries were also significantly higher at storage temperature of 5C and increased with increasing duration of storage. The most suitable storage for guava was at 10C. At this temperature, hydro-cooled guava showed better visual appearances up to 4 weeks of storage compared to 1 week at 5 and 15C. In conclusion, this study showed that pre-cooling (by hydro-cooling) and cold storage temperature could maintain the quality and extend the shelf life of guava. |
