Abstract: | Abstract Rice bran extract (RBE) was fractionated by using ultrafiltration techniques. The obtained retentate (R) inhibited the browning of potato puree to a similar extent as RBE and more than it's permeate. The R that was incubated at pH 4.0, 5.0, and 6.0 inhibited the browning of potato puree more than R that was incubated at pH 7.0 or 8.0. Potato puree that was treated with heated R at 80°C for 10 min had a browning value similar to that of puree treated with unheated R and lower than those treated with heated R at 40 or 60°C for 10 min. |
