A food scientist’s job is to study, create, and evaluate various ingredients and foods, ensuring that they are healthy for consumption by humans. To develop new technology and methods of food manufacturing, distribution, and packaging, they use their knowledge of life and physical sciences. Regulatory elements are often applied, ensuring that the final product meets the quality and safety requirements as specified by that country’s food laws and regulations. To specify specific nutritional details for product labels, they use analytical techniques; study new ways to keep food fresh and healthy for a longer duration; focus on manufacturing methodologies to minimize time and expense while retaining nutrients and quality; ensure that the food is nutritious and that there is no chance of contamination.
