Notes:
A lithium acetate-dimethyl sulfoxide ninhydrin reagent was shown to be useful for reaction of amino groups in a series of structurally diverse food proteins and flours of variable lysine content. The proteins were bovine serum albumin, casein, hemoglobin, lactalbumin, lysozyme, soybean protein, soybean trypsin inhibitor, trypsin, and wheat gluten. The flours were barley, high lysine corn, high protein rice, lima bean, nonfat dry milk, rice, soy, and wheat. The ninhydrin-reactive lysine content of these proteins varied from 63-109% of the theoretical values. This variation needs to be taken into account in possible applications of the ninhydrin reaction to food proteins.
