Describe the process of bringing a food from its original source to the consumer. Part Two
The Food Supply in the United States • Begins with the PRODUCERS • Farms, ranches, fisheries • Large Producers are usually more efficient and help meet global food needs, but, they may stress the land and require more fertilizers and pesticides, raising costs and potential health concerns. Long distance shipping can further raise costs and decreasing food quality. • Small farms tend to stay local and are usually good for the environment as a result of less transporting.
The Food Supply in the United States • Continues to the PROCESSORS • Various processes can change the characteristics of the food and extend the life of the quality of the food.
Food Processors Make it Happen! Soak, pulverize, treat with acid and package corn Clean and Package Dry and Ground and package More steps
How Do Processors Preserve Shelf Life? • Shelf Life is the amount of time a food maintains quality. • A Shelf Stable food does not need refrigeration • Methods to Extend Shelf Life include: • Canning – sealing in airtight metal or glass and then heating to destroy harmful microorganisms • Freezing – slows the growth of harmful microorganisms • Curing – adding salt, spices, sugar and or sodium nitrate to slow the growth of harmful microorganisms • Drying – removing the moisture needed for the growth of harmful microorganisms • Freeze Drying – freezing first and then drying to retain flavor, texture and nutrients better • Controlled Atmosphere Storage – packaged with a specific mixture of nitrogen, oxygen, and carbon dioxide
Processors Can Also Use Additives • Some food additives occur naturally • Some food additives are chemical combinations created in a lab • Over 3000 are in use • Monitored by the FDA – Food and Drug Administration • Have specific uses
Additives are used to: • Add Flavor – growing and processing conditions can cause loss of or inconsistent flavors • Improving Nutrition • Increasing Shelf Life – delaying spoilage • Maintaining texture – which can be lost during processing • Helping foods age to create new foods

The Processors are also in charge of Packaging • Packaging needs to preserve quality, shape and appearance of the product. Stay tuned
