Food technology is a wide area of study because there are so many things that people do with food. Your correspondence studies might include courses on how to cook or how to mass-produce food, such as in fast food restaurants or factories. Other courses might deal with nutrition, how food is grown and harvested, and even foods that are "made" in a factory with synthetic ingredients. The coursework will vary in terms of its focus, but many courses fit into the broad spectrum of food technology.
Food technology courses taken through correspondence courses can lead to several diplomas or certificates -- or maybe none at all. A degree in food technology usually certifies you to work somewhere in the production of food, but other degree options could include cooking or nutrition degrees. Some programs do not offer diplomas and are designed to give you information in a specific area that you can then apply to your job search.
Many schools and programs offer correspondence courses in food technology. Major online schools, such as the University of Phoenix, Minnesota School of Business, American University and Study Nation, offer food technology courses via correspondence. So do local schools with food technology programs. These local schools may be trade schools or community colleges that have online or correspondence options. Online and distance learning schools also offer correspondence courses taken via email, blog posts and websites.
Food technology correspondence courses can lead to several different career options. You can become a cook or chef, working in a kitchen or restaurant. Degrees from University of Phoenix, National American University or any culinary college can facilitate this career. You can manage an eating establishment, become a produce buyer or work with a nutritional program designing menus. You could also create a specific type of food or food idea to mass-produce in a factory. However, you will need a food production degree for these types of jobs. National American University, Minnesota School of Business, Study Nation and hundreds of other schools offer this type of degree.
