Wood - Wood - Properties of wood: Sensory characteristics include colour, lustre, odour, taste, texture, grain, figure, weight, and hardness of wood. These supplementary macroscopic characteristics are helpful in describing a piece of wood for identification or other purposes. Colour covers a wide rangeyellow, green, red, brown, black, and nearly pure white woods exist, but most woods are physical properties of food materialsThermal Property of Food - an overview | ScienceDirect TopicsKnowledge of thermal properties of food products is needed in design of cooling, freezing processes, and equipment, as well as cooling load calculations. Data on thermal properties of some foods are given in Table 15.3. Thermal conductivity of ice (k=2.24 W/m K) is around four times that of water (k=0.56 W/m K). Consequently, thermal conductivity of frozen foods will be three to four times Texture Analysis | Why Measure Texture?Texture analysis is the mechanical testing of food, cosmetics, pharmaceuticals, adhesives and other consumer products in order to measure their physical properties. Because of its adaptability, texture analysis has become commonplace in many industries to measure a specific or range of characteristics or properties relating to the way a physical properties of food materials
