Food technologists study the chemical, physical and microbiological makeup of the food and are involved in its processing, preservation, packaging and storage in safe, wholesome and nutritious form. Food technologists are mainly required in food industries, mills, distilleries, packaging industry and hotels. They are employed as professionals in quality assurance, food production, analytical and research laboratories and new product development.
