摘要
Extracting a red carotenoid pigment from processing waste which comprises a milky-pink watery mixture containing dissolved and finely divided material from the waste. To this is added a small quantity of a triglyceride oil, such as soybean oil. The oil is dispersed in the watery mixture with the aid of turbulent mixing, after which the dispersion is heated and the oil fraction recovered by centrifugal extraction. The resulting dark-red oil is suitable for incorporation in commercially produced salmon and trout feed to improve the fishes' flesh and skin coloration.
