摘要: Abstract This chapter covers the process-induced formation of d -amino acids and cross-linked amino (CLAAs) in food. The industrial processing food feed proteins often includes treatment heated alkaline or acidic solutions. Such treatments lead to two major chemical changes: CLAAs, such as lysinoalanine, lanthionine, histidinoalanine, racemization free protein-bound l into their -isomers. Both represent undesired contaminants particularly because they diminish digestibility nutritional quality may exert toxic properties.
