Microbiological Determinations of Amino Acids in Foodstuffs. I.

Abstract
Meat meal, lupine meal, bean meal, unpeeled potato, oat meal and barley meal were analyzed for 18 amino acids. Values are expressed as: (1) percentage for ash- and moisture-free material, (2) percentage in crude protein (total N in hydrolysate x 6.25) and (3) amino acid N in percentage of total N in hydrolysate. Analysis of field bean has not been previously carried out and is inferior to soy bean as a potential source of essential amino acids. A comparison of Swedish oat and barley with that of oat and barley grown in U. S. A. shows comparatively good agreement.
