To prove the labeling to be correct general properties, additives and sterol were analyzed in 13 kinds of commercial household margarine (7 kinds of soft type in a cup and 8 kinds of carton packaged), manufactured in summer and winter, and the following results were obtained.<BR>1) There was hardly any difference in the amount of oil, water and vitamin A content, and in the melting point between summer and winter products, and between the soft and hard type. There was also no difference in saponification value and iodine value between summer and winter products, but the iodine value was higher in the soft type margarine.<BR>2) Cholesterol was detected in all the samples but the value was very slight and there seemed to be no addition of animal fat in any of the samples. Avena sterol was detected in the sample labeled as containing safflower oil. Synthetic antioxidants and preservatives were not detected in any of the samples, and the labeling was proved to be correct.<BR>3) Compositional ratio and content of sterol varied somewhat between winter and summer products but the difference was small.
