食品物性学复习题（Review of physical properties of foods） 1. what is food property science? What is the content of the study? A subject that studies the physical properties of food and its raw materials The main research contents are the mechanics of food and food raw materials, official studies, thermal and electrical characteristics, etc. 2. what are the factors that determine the quality of the food? Visual induction, chemical induction, textural properties of foods, nutritional value 3 what are the micro morphological structure of food? Crystalline, liquid, gaseous, transition states: glassy and liquid crystalline states 4 Classification of non Newton fluids, characteristics, brief answer 1) the relation between time and time is divided into two kinds: Irrespective of time, it includes pseudoplastic fluid, dilatant fluid, and plastic fluid. The change in apparent viscosity is independent of the time applied to shear stress Relating to time, including thixotropic fluids and thixotropic fluids, characterized by changes in apparent viscosity with time Non Newton fluid has nothing to do with time can be divided into plastic fluid and non plastic fluid. The limit of the shear stress is defined as the value of the yield stress. The plastic fluid can be divided into Bingham fluid and Bingham fluid. The yield stress of more than 0 sigma of Bingham fluid flow characteristics, flow law. Non Bingham meets Newton Newton does not meet the fluid flow rule. Non plastic fluid to pseudoplastic fluid and dilatant fluid. Pseudoplastic fluid in non Newtonian fluid flow equation, when 0n1, the viscosity decreases with increasing shear stress. Dilatant fluid in non Newtonian fluid flow state equation, 1n infinity, its viscosity with shear the stress increases. 5, commonly used viscosity representation method? Relative viscosity; specific viscosity; specific viscosity; viscosity; Logarithmic Viscosity; intrinsic viscosity Short answer. All the requirements, I think the name of the Greek alphab
