Depending on their area of specialization, Food Scientists may develop ways to process, preserve, package, or store food, according to industry and government specifications and regulations.,4,Food Processing,Food processing,is the set of methods and techniques used to transform raw ingredients into food for consumption.,Examples of food processing methods include:,Chopping,Mixing,Homogenizing,Cooking,Pastuerizing,Emulsifying,Spray-drying,5,Food Processing,From Farm,To Table,?,Whey protein, a by-product,of cheese manufacturing, is,used in energy bars and drinks!,6,Food Preservation,Food preservation,is the process of treating and handling food in such a way as to stop or greatly slow down spoilage to prevent foodborne illness and extend its shelf-life.,Food processing methods that are used to preserve foods include:,Refrigeration and freezing,Canning,Irradiation,Dehydration,Freeze-drying,Pickling,Pasteurizing,Fermentation,7,Food Preservation,How a food is processed can affect its appearance, odor, flavor, and texture.,Over the years many food preservation methods have been improved to increase the shelf-life of foods while minimizing changes to the quality and nutritional content.,IQF or Individual Quick Freezing,has improved the quality,of frozen fruits and vegetables,8,Food Preservation,Many food preservation methods have also been used to create foods for astronauts and for the armed forces. These foods must remain safe to eat over a long shelf-life.,It is reported that M & Ms were developed when Forrest Mars, Sr. saw soldiers eating candy coated chocolate. The chocolate pellets that the soldiers were eating were coated in sugar to increase their shelf-life in hot climates and prevent the chocolate from sticking to the soldiers fingers!,Bags of Space Station,food and utensils on a tray.,9,Food Preservation,So, how does food preservation work?,All of the food preservation processes work by slowing down the activity and growth of disease causing bacteria, or by killing the bacteria all together. They also slow down or stop the action of enzymes which can degrade the quality of the food.,Temperature,Water Activity,pH,10,Food Preservation,How a food is packaged also influences its shelf-life.,It is also important that foods are handled properly by the consumer at home.,Check “Use By” or expiration dates.,Follow storage or preparation instructions.,11,Careers in Food Processing,Job Titles:,Process Engineer,Engineer,Employers:,Food processors,Ingredient manufacturers/suppliers,Academia (Higher Education),Contract research laboratories/development firms,Self-employed/Consultant,Responsibilities:,Process design,Bench-top process development,Testing,Plant scale-up,Commercialization,Troubleshooting,12,Careers in Product Development,Job Titles:,Product Development Scientist,Scientist,Employers:,Food processors,Ingredient manufacturers/suppliers,Academia (Higher Education),Contract research laboratories/development firms,Self-employed/Consultant,Responsibilities:,Bench-top development,Testing,Plant scale-up,Commercialization,Troubleshooting,13,Want to learn more?,Visit:,Find a Food Scientist:,A database of IFT members whoare willing to,provide more information about the field of food,science to you,14,Questions?,15,Activity,Got Milk?,16,Headquarters,525 W.
