Description
Summary:A technologically feasible cottonseed oil-isopropyl
alcohol (IPA) miscella refining process was developed to
and 4% (w/w) acid activated bleaching clay,
and phosphorus content. The water washed and dried oils
determined and improved. These were: 1) homogenization
developed in this study could produce a higher quality
drying; and 6) bleaching. In neutralization, the
excess) by using a Sonolator for 15 times. The refined
from the bottom and top layers were treated with 0.5%
from the cottonseed oil-hexane miscella.
hexane systems showed that the new refining process
layers; 4) desolventization, 5) water washing and
miscella was mixed with 20 Be' caustic solution (50%
necessary to refine cottonseed oil-IPA miscella were
obtained. However, the quality of the bleached oil
of the cottonseed oil-IPA miscella with caustic
oils from both the bottom and top layers were water
produce high quality cottonseed oil. Individual steps
produced from bottom layer was better than that from the
refined oil from the cottonseed oil-IPA miscella than
respectively. Good quality refined and bleached oil was
respectively. The water washing efficiently recovered
solution; 2) centrifugation; 3) separation of miscella
the oil from the top layer miscella and reduced the soap
top layer. Comparative experiments with both IPA and
