✦ Synopsis

Rice polish" is a comparatively new cereal substitute, being the waste which comes from the rice in the polishing process whereby the outer layers of the grain, containing: phosphorus, are removed. Formerly this rice polish was sold by the ton for stock food, but Miss Rona K. Armstrong, of the United States Department of Agriculture, visiting New Orleans, discovered it and had it placed on the market for making conservation bread in proportions of one-fourth rice polish to three-fourths wheat flour. The Flour and Grain World describes methods of cleaning and polishing rice whereby this product is obtained. Rough rice from the thrashing machine is first separated from thrash, the hulls or chaff removed by rapidly revolving millstones, and the outer skin of the grain then removed by pounding in huge mortars, which gives a mixture of clean rice, fine chaff, and flour. The rice is then polished by friction against moose hide or sheepskin, tanned and worked to a high degree of softness, where the outer layers of the grain are moved, yielding rice polish, which is said to contain the most nutritive portions of the grain.
