Abstract
This study was made as a trial to discover other natural antioxidant
ch is prepared from commerc~ soybean phosOhohPids This new
zroxida~t can be used instead of synthetic antioxidants which caused
~~gerou5 diseases such as cancer This study was also made to improve
te surface propethes of soybean phosPh0hP~5 and its comP0n~t5 by
s reaction with propylene oxide.
Aver the extraction of soybean oil by hexane or by mechanical way
~speller) extraction of gums (commercial ~hosph0hP~5) from the oil
ere done and the soybean phospll0liP~ was purified and fractionated
~v using column chromat0~aP~ to get P.C., P.E. and PA.
z- The U N., 1 .R. of the volatiles which obtained from roasting of total
soybean phospholiP~5 and its fractionated products at different
:einperatu~s (120, , 160 and 200°C ), were examined
3~ These ~o analysis and using GC instrument are the ways to identi~
the obtained volatiles which consisted of unsat ated compounds such as
aldehydes, ketones, azido etc.
4- No real difference was found in the physical and chemical propeuies
be~een soybean oil extracted by solvent (hexane) or expeller except in
I peroxide value
