Notes:
Flavor deterioration of salad dressings was investigated to determine the effect of hydrogenation of the oil, additives and storage conditions. Flavor quality tests were developed and correlated with gas chromatographic analyses of volatile compounds in oils separated from the dressings. Hydrogenation of soybean oil with copper and nickel catalysts effectively increased the storage stability of salad dressings at 21°C but not at 32°C. The use of BHA as an antioxidant in the oil or EDTA as a metal inactivator in the starch base as well as nitrogen packaging were effective in prolonging the storage stability of salad dressings made with unhydrogenated soybean oil. Therefore, these additives or nitrogen packaging may provide economic substitutes for hydrogenation of soybean oil used in salad dressings.
