Thesis Title
Prevention of Plasmin-induced Hydrolysis of Caseins

Read article at Massey Research Online:

Bovine plasmin is a proteolytic enzyme that is naturally present in milk and is responsible for proteolysis (the breakdown of proteins into smaller polypeptides or amino acids), age-gelation and bitterness in various milk products. Mr Bhatt''sresearch aimed to understand and control the plasmin-induced hydrolysis (water dissolution) of caseins (proteins) in milk products. He explored specific casein modifications and developed a mechanistic understanding that has enabled the development of technologies for the prevention of both enzyme activation and action. This ground-breaking research has led to the recommendation that targeted lactosylation at industrially relevant levels can be used to extend the shelf life of UHT milk products. A new understanding of the mechanisms of casein micelle dissociation was developed and can be used to understand the mystery of Age Gelation in UHT milk.
