INFLUENCE OF WATER CONTENT ON THE STABILITY OF MYOGLOBIN TO HEAT TREATMENT
ABSTRACT The effect of heat treatment on a model protein, sperm whale myoglobin, at various water contents has been investigated at neutral pH. Samples ranging from solid preparations of 3% water content to dilute solutions of 99.6% water content have been examined. Differential scanning calorimetry...
