ABOUT THE COURSE:
Food science is an essential field that integrates the study of food, its properties, and its impact on human health and the environment. This course, "Food Science and Technology," is designed to provide comprehensive knowledge on various aspects of food science, including its structure, chemical processes, and nutritional significance. Understanding these principles is crucial for ensuring food quality, safety, and sustainability in today's rapidly evolving food industry. The course will cover topics such as the relationship between food production, environmental sustainability, and public health; the physical and chemical structures of food components; and the key chemical reactions and processes that occur during food preparation, preservation, and storage. Additionally, students will learn about sensory evaluation, the role of macronutrients and micronutrients in human health, and the microorganisms associated with foods.
This course will delve into the importance of food additives and contaminants, food preservation techniques, and the principles of food formulation and processing. Furthermore, it will explore the application of AI-ML and impact of Industry 4.0 technologies on food manufacturing and the application of a circular economy in the food industry to reduce waste and improve resource efficiency. By providing detailed information on these topics, the course aims to create a knowledgeable workforce equipped to tackle the challenges of the modern food industry, contributing to academia, research, and development. The course materials will also be beneficial for preparing for competitive examinations like GATE, NET, and ARS.
