The cross-linking of proteins results in a change in the specific structure of a protein. These structural changes result in different behavior of the protein in food. This research focused on the cross-linking of the milk protein α lactalbumin … the enzyme peroxidase. Theoretically, this protein can form cross-links at multiple places which result in the formation of many different new protein structures. Each of these protein structures having their own behavior. Directing of the cross-linking reaction was the main theme of the research to decrease the number of protein structures formed. The specific site of cross-linking was an important part of the research. Cross-linked α lactalbumin shows a decreased formation of foam in comparison to the starting protein. Therefore the cross-linked α lactalbumin can be used as an anti-foam in foods.
