| Abstract: | REFERENCE to the above chart shows that there are scarcely any two samples that have the same chemical and physical characteristics. Such information shows that there is a very definite need for developing standards for cod liver oil intended for industrial use. Establishing standards for cod oil would have a twofold effect. It would cause the cod oil producer so to control production conditions that he could supply the trade with cod oil of uniform quality which complied with the established standards. This in turn would provide the tanner with a standardized cod oil which would be of material assistance in the manufacture of uniform leather. This would particularly apply in the manufacture of chamois leather which involves a chemical rection between collagen, the leather forming substance of the skin, and the fatty acids of an easily oxidizable oil such as cod oil. Thus it is evident that there is a definite need for developing standards for cod oil. It is also obvious that the adoption and use of such standards by the trade would serve to stabilize the cod oil industry which is now controlled by empirical procedures. |
