Food Science is the multidisciplinary study of food and the
application of knowledge thus gained to the development of food
products and processes, the preservation and storage of foods, and
the assurance of food safety and quality. Nutrition, nourishment,
or aliment, is the supply of materials - food - required by
organisms and cells to stay alive. In science and human medicine,
nutrition is the science or practice of consuming and utilizing
food. We know that the food we eat is digested and it is absorbed
and utilized by the body. Food helps us in staying healthy. Our
diet should be such that it meets our nutritional requirements and
thus helps us in our health. Although food occupies the first
position in the hierarchy of our needs, ignorance of many basic
facts relating to food and nutrition is still widespread. All of us
eat food every day - but have we ever paused to consider if our
diet is balanced? In fact, do we even know what kinds and amounts
of foods would make our diet balanced and lead us toward good
health? Buying and cooking foodstuffs is a common experience for
all of us. However, when purchasing, do we really know how to
select the food items? Do we know the household ways of finding out
whether the food item is adulterated? If the diet is not balanced,
the result would be malnutrition and nutritional deficiency
diseases. So, we find out the type of diet that should be eaten by
a person who is suffering from a disease - from fever, diarrhea,
and diabetes to hypertension. Activities of food scientists include
the development of new food products, design of processes to
produce these foods, choice of packaging materials, shelf-life
studies, sensory evaluation of products using panels or potential
consumers, as well as microbiological and chemical testing. Food
scientists may study more fundamental phenomena that are directly
linked to the production of food products and its properties. Food
science brings together multiple scientific disciplines. It
incorporates concepts from fields such as microbiology, chemical
engineering, and biochemistry.
