What other fields of study are related to food science and how are they related to it? Food Technology- is the use of the information generated by food science in selection, preservation, processing and packaging and distribution as it effects the consumption of safe, nutritious and wholesome food. Food science is a broad discipline which contains within it many specialisations such as Food Microbiology is the study of the microbial ecology related to foods, the effect of environment on food spoilage and food manufacture, the physical, chemical and biological destruction of microorganisms in foods.

Grade 12 Agricultural Science Notes Animal nutrition 1. Bile contains bile acids, also known as bile salts, that cause large fat globules to break down into microscopic globules. Fats are usually stored under the skin, and around some organs. What are the 6 classes of nutrients? The wall of the villi is only one cell thick — decreasing diffusion distance.
Eating foods with high sugar and carbohydrate content. Herbivores, such as gorillas, cows, hares, and many snails, eat mainly autotrophs plants and algae. Balanced Diet.

The ileum is a site of both digestion and absorption. In Life Orientation and Naturals Sciences you would have discussed healthy diets and the correct nutrition for humans. They are harder to break down, however, so are used as a long term energy store. In general, animals fit into one of three dietary categories.

As a branch of Applied Chemistry the food chemistry deals with the chemical examination and analysis of food and food components, and studies the chemical aspects of food technology. The essential aim of food chemistry is the control and the guarantee of a high and unloaded from foreign substances quality of our food, to which the consumer as the legislature imposes high quality requirements. For the assessment and analysis of food, the whole range of chemical and physical methods, as well as special examination procedure is ready. Chemistry of Food I Lecture notes.
