| dc.description.abstract | The effects of different concentrations of Aloe vera gel (50%, 75% and 100%) and honey
(25%, 50% and 100%) on physico-chemical changes in fresh cut pineapple stored at 40C
were assessed in this research work. Pineapples were washed and cut into 2cm pieces.
Then the pineapple pieces were coated by different concentration of Aloe vera and honey
by dipping for 2 minutes and stored at 4ºC for 12 days. The amount of juice leakage,
firmness, pH, total soluble solids, vitamin C content, color and microbial load were
observed during storage. Sensory testing was carried out to assess their acceptability. A
significant variation was observed in weight loss, vitamin C, color, flavor and textural
properties in all treated samples compared to control during entire storage period studied
(12 days). Treatment with 100% Aloe vera gel was found most effective to prevent
physico-chemical changes and to increase the shelf-life of fresh cut pineapple among the
treatments. In addition, at the end of storage period, the highest amount of vitamin C
(27.35 mg/100g) was resulted in sample coated with 100% Aloe vera. The results
obtained in this study showed that Aloe vera gel could be used as effective coating
material to prevent the physico-chemical and microbial changes in fresh cut pineapple
during storage at refrigerated condition. | en_US |
