Abstract

The objectives were (1) to produce soy oil conjugated linoleic acid (CLA) triacylglycerides in large quantities with solar light photoisomerization, utilizing iodine as a photosensitizer, (2) to study the temperature variation in the photoisomerized oil during various hours of the day, and (3) to study the variations in solar light intensity during various hours of the day. A 0.5% iodine containing soy oil in glass box with a glass lid was photoisomerized, under natural solar light for 0, 11, and 27 days, and CLA isomers were determined with gas chromatography with flame ionization detector. After 27 days of solar light photoisomerization, the cis-9, trans-11 CLA; other cis, trans CLA; trans-10, cis-12 CLA; trans, trans CLA, and total CLA were found to be 0.62 ± 0.05%, 1.04 ± 0.09%, 0.54 ± 0.11%, 6.16 ± 0.68%, and 8.37 ± 0.90%, respectively. The concentration of CLA isomers between 0 and 11 days was significantly different (p < .05), and the concentration of CLA isomers between 0 and 27 days was also significantly different (p < .05). There is no significant difference (p > .05) in CLA concentration between 11 and 27 days treatment. The CLA was not found in control soy oil samples. The CLA isomers were measured with GDFID in 45 min instead of 120min. The temperature of the edible oil in glass boxes ranged from 26 °C (8 a.m.) to 56 °C (1 p.m.). The light intensity ranged from 4,146 lux (7 p.m.) to 95,490 lux (12 p.m.). Glass lid on the glass box affected light transmission to a small but statistically significant extent (p < .05). The CLA isomers could be energy efficiently and inexpensively produced in soy oil by solar light photoisomerization, at low temperature and without needing expensive reactor vessels or catalysts
