Show WHAT MAKES YELLOW BUTTER Real Source and Nature of Natural Color Found by Dairy Department of Missouri College. Everybody likes yellow milk and butter, but-ter, but sometimes the color is absent. This absence Is especially noticeable In butter. Chemists Investigated the cause of .this variation In eglor as long ago as 1830, but It remained for the dairy department of the University of Missouri college of agriculture to determine de-termine the real source and nature of the naturul color of dairy products. Three years of Investigation rjot only showed the cause of the naturul color but' made clear the nature and source of the yellow color thut Is found in the body fat of cattle. The color In the tallow Is exactly the same as thut found In butter. Cows that give yellow yel-low butter have yellow body fat, while those which give a whiter butter have whiter body fat The coloring matter In both cases Is carotin, so-called since It was first found In carrots. The yellow color in milk and butter Is not made by the animal an-imal but comes from the feed. This coloring substance Is found In all green leaves, which accounts for the yellow butter In summer. By continued feeding feed-ing pf feeds free from coloring matter it was possible, In the experiments con-1 ducted by the Missouri college of agriculture, agri-culture, to obtain white butter from a Jersey cow. As a result of the work a list of feeds that will give yellow butter but-ter and those that will not Is available. |
