title: [Influence of various thermal processes and microwaves on the amino acid composition of food products: implications on their nutritional value].
abstract: The cinetic study of free amino nitrogen and total soluble nitrogen of hard wheat semolina, when comparatively treated by thermal processings (convection and microwaves) shows a decrease conditioned by time and strength of heating. Aminograms show the same decrease, which is however different for each amino acid. After thermal treatment, appear ninhydrin-reactive substances, to be identified. In short, micro-wave heating seems to have the same effect as conventional heating, on free amino acids of these cereal products.
