The EU method based on this variant therefore suggests neutralization of the hydrolysates, which can be readily automated, or the partial removal of the hydrochloric acid by distillation. 1). Toran et al. (1996) also suggest oxidation for the determination of cystine and methionine in infant formulas. 17 Slump and Bos (1985) describe an interference of the oxidation of methionine, if chloride levels from salts far in excess of 1% occur in for example supplementary feeds or concentrates. This causes the performic acid to be partially degraded, while forming chlorine, so that only cysteic acid but not methionine sulphone is formed completely.
Carisano (1993), who employed microwave hydrolysis with lithium hydroxide under temperature control, was able to hydrolyse meat and fish completely in less then 60 min, obtaining results similar to those with barium hydroxide (110°C, 12 h). He derivatized tryptophan with o-phthaldialdehyde (OPA) prior to HPLC, whereas Algeria et al. (1996) converted with phenylisothiocyanate (PITC). An expert group of the EU Commission, DG XII, has been working for 4 years on comparative studies with a view to establishing a harmonized system of feedstuff analysis in the EU.
