Oxidized Flavor in Milk. VIII. The Effect of the Degree of Saturation of Fat in the Ration of the Cow upon the Iodine Number of the Butter Fat and the Susceptibility of the Milk to Metal-Induced Oxidized Flavor

摘要: Summary 1. The feeding of 1 pound per day cocoanut oil in the daily ration a dairy cow decreased slightly iodine number resulting butter fat and reduced intensity oxidized flavor developed by copper. 2. either expeller, crude, or refined soybean increased greatly susceptibility milk to metal-induced flavor. 3. difference lecithin content different types oils produced no noticeable change on development 4. hydrogenated fat. This is believed be due desaturation this cow. 5. In rations low does not appear correlated with developed. Apparently other factors are more importance. 6. these experiments range has been from 23 as an average for supplement 48 expeller oil. 7. Under conditions experiments, approximately three weeks were required before had reached period maximum change.
