摘要: Food materials are nonequilibrium systems and show time-dependent characteristics. Various changes in food structure may occur processing storage. Structural relaxation times important measures of rates the Deborah number be used as a parameter to establish relationships with real-time properties. solids often amorphous undergo structural transformations such collapse phenomena Common examples stickiness caking powders. composition also related component crystallization. Crystallization occurs commonly sugar-containing retrogradation starch is well-known defect starch-containing common cause bread staling.
