Food technology is the application of food science to the selection, preservation, processing, packaging, distribution and use of safe foods. Related fields include analytical chemistry, biotechnology, engineering, nutrition, quality control, and food safety management. Basically, the study of how microorganisms interact with food, food microbiology focuses on bacteria, molds, yeasts and viruses. The areas of special importance for product development are food safety and quality.
Food safety is concerned with the prevention of pathogens in food. It's almost impossible to eliminate microorganisms from any food, but many steps can be taken to slow their growth or inactivate them. What food science is doing in the area of food safety is to develop very sensitive and rapid techniques to identify pathogenic microorganisms and the toxins they produce in food, and to develop packaging and processes that inhibit their growth and reduce their survival rate. Not all microorganisms are harmful, but some cause food to deteriorate.
The key to controlling deterioration is to kill as many bacteria as we can without also killing the quality of the food in which they reside. Food microbiology is one of the most important fields of food science when it comes to product development, especially in this era of litigation. When designing a development plan for a new product, it is essential to consider the microbial quality of each component and how that may affect the overall quality of the product, and determine how to process the product so that it has a sufficient shelf life. When it comes to product developers, food engineers develop the concepts that processors use to convert raw materials into safe, durable foods.
In menu development, engineers may not play a direct role, but processors do. The way an ingredient is processed can have a dramatic effect on the flavor, color, safety and shelf life of foods. Consider high-pressure processing (HPP) and its effect on the fresh fruit and vegetable juice industry. HPP is a non-thermal or “cold pasteurization” process developed to allow the production of fruit and vegetable juices without any of the harmful effects of heat treatments, such as changes in flavor, texture or color.
The nutritional profile of juices is not altered by the process, so there is no need to fortify them. Nutritionists often associate heat processing with detrimental effects on the nutritional quality of foods, but not always. Recent work at Cornell University showed that heating tomatoes increases the level of a cancer-fighting phytochemical called lycopene. Winsight is a leading B2B information services company focused on the food and beverage industry, providing information and market intelligence to business leaders from all channels where consumers purchase food and beverages (convenience stores, grocery stores, restaurants and non-commercial food services) through media, events, data products, advisory services and trade shows.
Departmental research areas are internationally recognized for their cutting-edge and industry-relevant research to protect public health, improve food quality, and achieve technological advances in the field of food science. Food science brings together multiple scientific disciplines. It incorporates concepts from fields such as chemistry, physics, physiology, microbiology and biochemistry. Food technology incorporates concepts from chemical engineering, for example.
Through master's programs, you can specialize in microbiology, food chemistry, sensory sciences, dairy product science, biochemistry, or processing. Doctoral programs usually have areas of emphasis, such as fermentation or food chemistry. Graduate programs are research-based and may include topics such as flavor chemistry, packaging methods, food allergens, toxicology, cereal grains, brewing, and international food laws. From researching the components of a given food to listing the nutrients in foods on a label, experts in food science and technology are involved in everything they can think of when it comes to food manufacturing.
The mission of the department is to generate knowledge about food through research and to apply and disseminate knowledge through teaching and dissemination, with the aim of ensuring the availability of safe, nutritious and attractive foods, with minimal environmental impact, for the benefit of all people. Food microbiology is the study of microorganisms that inhabit, create, or contaminate food, including the study of microorganisms that cause food spoilage. The food industry, which originally provided only primary products for final preparation at home, is responding to market demands for more refined, sophisticated and convenient products. In basic terms, Food Science and Technology deals with the study of the compositions of foods and the search for ways to refine them.
The process wasn't called canning then and Appert didn't really know the principle behind which his process worked, but canning has had a big impact on food preservation techniques. Molecular gastronomy is a subdiscipline of food science that seeks to investigate the physical and chemical transformations of ingredients produced in the kitchen. One of the main challenges for product and menu developers is to provide tasty foods that contain fewer calories but that, at the same time, satisfy the customer. To work in the food science and technology industry, you must be able to communicate effectively, pay attention to detail, apply statistics, and work as a team.
Food technologists research, develop and test food products, analyze crops, and apply new methods to improve food quality. Food Science is a practical name used to describe the application of scientific principles to create and maintain a healthy food supply. All foods are biochemicals because, in most cases, foods or their raw ingredients are or were living entities. The ability to perform analysis of food components is developed in conjunction with statistical methods of quality control.
As a Food Science student, be prepared to take food-related courses in fields such as chemistry, microbiology, nutrition science, biology, physics, agricultural science, food safety, product development, sustainable food production, and many others. . .
