Abstract

Abstract: Textural properties and water holding capacities(WHC)of myosin-collagenous protein and myosin-gelatin mixed gels were studied.The results showed that the values of the hardness,springiness and WHC of myosin-collagenous protein and myosin-gelatin mixed gels were higher than those of pure myosin.The values of the hardness and WHC of myosin-collagenous protein mixed gel were lowest at pH6.5,whilst the value of the springiness was highest.The hardness and WHC of the myosin-collagenous protein mixed gel increased with the ionic strength,whilst the springiness was the opposite.The springiness of myosin-collagenous protein mixed gel could be improved by adding KCl,and the WHC could be improved by adding SPP and TPP.The values of hardness and springiness of myosin-gelatin mixed gel were highest at pH6.5,whilst the value of the WHC was highest at pH6.0.The hardness and springiness of the myosin-gelatin mixed gel increased with the decrease of ionic strength,but the WHC was the opposite.

Key words: myosin, collagenous protein, gelatin, textural properties, water holding capacity
