Abstract :
Showing the occurrence of glass/rubber transition in bovine serum albumin (a globular protein) at
low moisture levels and the occurrence of Maillard crosslinking in gelatin in previous works, the importance
of the state of glass or rubber of BSA on the rate and extent of polymerisation, protein solubility, colour and
SDS PAGE patterns in the presence and absence of ascorbic acid, diketogulonic acid and dehydroascorbic
acid was investigated. BSA on storage with Ascorbic acid and its degradation products at low moisture
contents (8.3% and 19.1%) at a relatively low temperature (40?C) can undergo chemical changes resulting in
marked increase in molecular weight, solubility decrease and formation of browning colour. The glassy state
data established the occurrence of chemical changes (Maillard
