A method for the iodine-catalyzed conjugation of soybean oil was developed, and the conjugated product was analyzed by UV, IR, and 1H NMR. The results indicated that the optimal conditions for conjugation included a temperature of 180?C, a catalyst loading of 0.5 wt.% and a reaction time of 3 h, at which the concentration of conjugated linoleic acid was 1.51 mol L-1, with 92 % conversion, the CLNA reached 0.225 mol L-1 when the temperature was 130?C, a catalyst loading of 0.5 wt.%, and a reaction time of 3 h with a conversion rate of 99.9 %. The reaction predominantly produced trans-trans, trans-cis and cis-trans isomers. It was also revealed that the conjugation of linolenic acid was much faster than that of linoleic acid. The method possessed the advantages of a short procedure, a high conversion rate, and no methyl esterification of the raw material, and it was an environmentally friendly technology that does not use solvents.

Cows were fed whole flaxseed or calcium salts of soybean oil as a fat source. Cows fed flaxseed had lower (P < 0.01) milk yield and higher (P < 0.01) percentages of fat and protein than cows fed calcium salts. Feeding whole flaxseed and calcium salts of soybean oil increased, respectively, the concentrations of alpha-linolenic acid and conjugated linoleic acid in milk.

Rate Of Decline

Some photoreactions of photosynthetic materials (corn chloroplasts, spinach chloroplasts and subchloroplast particles rich in System II) are examined at 77°K. The fluorescence yield of chlorophyll is observed to decrease reversibly upon irradiation at 77°K. The presence of ferricyanide in the chloroplast preparations increases the rate of decline of fluorescence yield while the presence of benzylviologen and phenazine methosulfate inhibits the decline of fluorescence yield. Extracts of Ricinus communis leaf (castor bean) also inhibits the decline of fluorescence yield. Data is given showing the effect of linolenic acid, extracts of Ricinus leaf, ferricyanide, benzylviologen and phenazine methosulfate on the ratio of fluorescence intensities at 725 and 700 nm.
