compares
the amount of oil extracted from bran treated by various methods of stabilization after 10 days. The results show that chemical stabilization, steaming, hot air drying and refrigeration successfully controls the lipase activity. The continuous horizontal line in Fig. 6(a) represents the total amount of oil
present in the bran. The dotted line shows the amount of oil
extracted from fresh bran (untreated—zero days). This shows
that 78% of oil present in rice bran is extractable in one extraction
step.
