ABSTRACT
The effects of pineapple shell extract (PSE) on browning in banana, potato, mushroom and
apple puree and slices compared to citric acid solution (pH 3.8) (PH) and distilled water (DW) were
investigated by measuring the changes of color and browning values. The browning value of banana
puree treated with PSE and PH were not significantly different. They had lower browning values than
that treated with DW after storage for 1 hour (p≤0.05). The browning values of banana puree treated
with PSE, PH and DW were 2.95, 3.04 and 4.27, respectively. The browning value of potato puree
treated with PSE was lower than that treated with PH and DW. Mushroom and apple puree treated
with PSE had higher browning values than that treated with PH and DW. On the contrary, banana
slices treated with PSE had a lower browning value than that treated with PH and DW during storage
for 2 hours. The browning values of banana slice treated with PSE, PH and DW were 2.00, 3.10 and
5.80, respectively (p≤0.05). Potato, mushroom and apple slices treated with PSE had browning
values similar to that treated with PH and DW. Therefore, the increase of browning in banana treated
with PSE seemed to be less than that of potato, mushroom and apple during storage.
