Food processing comprises various forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods. Track Chemistry of Food and Bio-processed Materials Chemistry of Food is the study of chemical processes and interactions of all biological and non-biological components of foods. Examples of biological substances are meat, poultry, lettuce, beer, and milk. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins , minerals, enzymes, food additives, flavours, and colours.
This discipline also includes how products get modified under certain food processing techniques and methods either to enhance or to prevent them from happening. Dairy technology is a branch of engineering that is concern with the processing of milk and its products. Dairy technology study involves processing, storage, packaging , distribution and transportation of dairy products by entailing the science of bacteriology, nutrition and biochemistry.
Track Food Microbiology Food microbiology is the scientific study of microorganisms that is used both in food and for the food production. This includes those microorganisms that contaminate food, as well as those which are used in its production; for example production of yoghurt, cheese, beer and wine. It is the study of the microorganisms that inhibit, create, or contaminate food, including the study of microorganisms causing food spoilage , pathogens that may cause disease especially if food is improperly cooked or stored; they are used to produce fermented foods such as cheese, yogurt, bread, beer, and wine, and those with other useful roles such as manufacturing of probiotics.
Track Food Choice and Consumer Behaviour Individuals make food decisions everyday based on past experience, perceptual differences, habitual intake and responses to environmental cues. Sensory science measures and evaluates the characteristics of foods that make them appealing to consumers.
This allows food companies to design foods that appeal to various market sectors, including children.
Methods from sensory science can also be used to understand biological variation that predisposes individuals to either consume or avoid foods that have potential to impact health and wellness. Track Food Nutrition and Dietetics Nutrition is the science that deals with the interaction of nutrients and other materials in food in relation to maintenance, growth, reproduction, health and disease of an organism.
It consists of food intake, absorption, assimilation, biosynthesis, catabolism, and excretion. The active management of food intake and nutrition are both key to good well-beings. Smart nutrition and food choices can help avoid disease. Eating the right foods can help your body deal with more successfully with an on-going illness.
Understanding good nutrition and disbursing attention to what you eat can help you maintain or improve your health.

Track Food Biotechnology Food Biotechnology is concentrated on evolving developments and solicitations of modern genetics, enzymatic, metabolic and systems-based biochemical processes in food and food-related biological systems. The objective is to aid produce and improve foods, food ingredients, and functional foods at the processing stage and beyond agricultural production, genetically modified plants are used to develop taste, shell life, nutrition and quality of food, genetically modified food is manufactured using biotechnological tools.
Track Food Preservation Food preservation is well-known as the science which deals with the process of prevention of spoilage of food thus permitting it to be stored in a fit condition for future use. Preservation safeguards that the quality, edibility and the nutritive value of the food remains undamaged. Preservation implicates avoiding the growth of bacteria, fungi and other microorganisms as well as retarding oxidation of fats to reduce rancidity.
The procedure also guarantees that there is no discolouration or aging and also involves sealing to prevent re-entry of microbes. Basically food preservation ensures that food remains in a state where it is not contaminated by pathogenic organisms or chemicals and does not lose optimum qualities of colour, texture, flavour and nutritive value.
Track Food Innovation and Management The notion of food innovation has been incorporated around food companies with growing regularity in recent years. Innovation experts generally split innovation into two high level categories: Disruptive and Incremental Innovation. Track Food Safety and Hygiene Food safety refers to controlling the presence of those hazards whether chronic or acute, that may make food harmful to the health of the consumer. Food safety is about producing, handling, storing and preparing food in such a way as to preclude infection and contamination in the food production chain, and to help ensure that food quality and goodness are sustained to stimulate good health.
Food hygiene is the conditions and measures necessary to certify the safety of food from production to consumption. Lack of adequate food hygiene can lead to foodborne diseases and can cause the death of the consumer. The objective of food hygiene is to make and deliver safe food and consequently contribute to a healthy and productive society.
Track Food Packaging The goal of food packaging is to safeguard the packed products and preserve their freshness. Food packaging is a synchronized system of formulating food for transport, distribution, storage, retailing, and finally to fulfil the desires of consumer at an appropriate cost. Thus the ideal packaging can diminish the large amount of food waste. Food packaging maintains food nutrition , swift and constant distribution of food among the value chain and decreases post-harvest losses.
Track Food Toxicology. Food toxicology deals with how natural or synthetic poisons and toxicants in various food products cause harmful, detrimental, or adverse side effects in living organisms. Food Toxicology shields with various aspects of food safety and toxicology, including the study of the nature, properties, effects, and detection of toxic substances in food and their disease manifestations in humans.
It will also include other phases of consumer product safety. Radioactive components, heavy metals, or the packaging materials used in food processing are examples of such substances. A food toxicologist studies toxicants in food, the health effects of high nutrient intakes, and the connection between toxicants and nutrients.
Track Food-borne Diseases Foodborne illness or foodborne disease or food poisoning is any illness resulting from the food spoilage of contaminated food, pathogenic bacteria, viruses, or parasites that contaminate food. Foodborne illnesses are infections or irascibilities of the gastrointestinal GI tract triggered by food or beverages that contain destructive bacteria, parasites, viruses, or chemicals.
The GI tract is a sequence of hollow organs joined in a long, twisting tube from the mouth to the anus. Common symptoms of foodborne illnesses are vomiting, diarrhoea, abdominal pain, fever, and chills. Track Advancement in Food Technology As the financial prudence of many countries are increasing, the customers have started using processed food more than the staples. As a matter of fact world-wide food processing technology business has extended to multi trillion dollars.
It was reported that around, 16 million people work in the food industry. Recent improvements in food processing and technology are not only important to meet the increasing productivity demands but to adopt erudite automation, control and monitoring methods and techniques. Track Management of Food Waste Food waste or food loss is food that is thrown away or lost uneaten.
The reasons of food waste or loss are several and occur at the stages of producing, processing, retailing and consuming. In the most recent years, food waste has become a multifaceted phenomenon attracting the attention of scientists, consumers and activists alike. Track Food and Agricultural Immunology Food and Agricultural Immunology present original immunological research with food, agricultural, environmental and veterinary applications.
It discusses an understanding of the interactions at the interface of the food and immune systems including studies on development of diagnostic systems - all types of ligand based assays, such as antibody and aptmer.
Nutraceuticals are those products apart from nutrition they are also used as medicine. A nutraceutical product may be defined as a constituent, which has physiological benefit and also provides protection against chronic disease. Nutraceuticals may be used to progress health, delay the aging process, preclude chronic diseases, increase life expectancy, or support the structure or function of the body.
