Thermal stability of invertase in reduced-moisture amorphous matrices in relation to glassy state and trehalose crystallization

The thermal stability of enzyme invertase in reduced-moisture model systems of maltodextrin (MD), polyvinylpyrrolidone (PVP; MW 40,000) and trehalose heated at 90°C was studied. Significant invertase inactivation was observed in heated glassy PVP and MD systems kept well below their glass transition...
