Effect of Pineapple Juice, Pineapple Shell Extract and Rice Bran Extract on Browning Prevention in Banana [Musa (AAA Group) Gros Michel] Slices and Puree
Abstract:
The effects of pineapple juice (PJ), pineapple shell extract (PSE) and rice bran extract (RBE) on browning in the banana slices and puree compared with citric acid solution (pH 3.8) (PH) and distilled water (DW) were investigated by measuring the color changes of the banana slices and puree. RBE treated banana slices had lower browning value than those treated with PJ, PSE, PH and DW after stored for 3 and 12 hrs (p≤0.05). Their browning values after 12 hrs were 12.05, 17.26, 17.56, 19.54 and 20.59, respectively. The L* values of banana slices treated with RBE were higher while its a* values were lower than those treated with PJ, PSE, PH and DW after stored for 12 hrs. The browning value of RBE treated banana puree (22.63) was lower than those treated with PSE (28.68) and PJ (32.26) after stored for 5 hrs (p≤0.05).The L* values of banana puree treated with RBE were higher whereas its a* values were lower than those treated with PJ, PSE, PH and DW after stored for 6 hrs. In conclusion, RBE could reduce browning in banana slices and puree more effectively than PJ, PSE, PH and DW.
