What affects the price of food
What affects the Price of Food?

  • Supply & Demand—

    • When there is greater demand, the price is higher

    • When there is greater supply, demand decreases, driving prices lower

    • Seasonal foods are a good example

  • Production & Distribution Costs

    • Rising fuel costs recently caused higher food prices on many items

    • The producers have to pass the costs along to the consumer


How does food get to your table
How Does Food Get To Your Table?

1) Production

  • crops are grown and livestock raised on the farm

  • Product developers work at food companies to research new ideas

    2) Processing

  • Foods go from the farm to a processing plant where they are cleaned, sorted, frozen, and/or packaged

    3) Distribution

  • Food is shipped from the plant to a distributor where food is stored in a warehouse, then sold to retailers

    • Advertising agencies promote foods

    • Retailers sell foods to consumers

      5) Consumers buy foods to serve and enjoy


Technology in our food
Technology in our Food

  • Technological advances in production, processing, storage and transportation have all given us more food options

  • Hydroponics—growing vegetables indoors in nutrient rich solution instead of soil

  • Fish farming—growing fish

    or shellfish in enclosed areas

    of water

  • Greater understanding of genes—

    How certain plants withstand

    weather conditions, etc.

Food processing today
Food Processing Today

  • Includes methods of preparing and handling food for safety, nutrition, convenience and appeal

    Preservation methods to increase shelf life include:

  • Freezing—slows down growth of bacteria that cause spoilage

  • Canning—using high heat to destroy harmful bacteria

  • Drying food—removes moisture bacteria needs to survive

  • Irradiation—passing food through radiant energy, such as an x-ray, to kill harmful bacteria

  • Curing—using salt, sugar, spices, and sodium nitrate or nitrite to preserve foods like ham


When was the last time you ate
When was the last time you ate….

  • Modified cornstarch, disodium phosphate, xanthan gum?

  • Monoglycerides, dextrose, agar, red 40 lake

  • Thiamine mononitrate, lecithin, sodium aluminum phosphate?

  • Maltodextrin, guar gum?

  • Corn syrup, citric acid?

  • Citric Acid, Sodium Citrate, Tocopherol?


Food additives
Food Additives

  • Additives—substances added to foods during processing to make them safer, more appealing or more nutritious. Reasons they are added include:

    • Preserving the shelf life—making it stay good longer

    • Increasing nutritional value—

      • Enrichment--putting back nutrients lost during processing

      • Fortification—adding nutrients that aren’t naturally present

    • Enhancing the flavor or appearance –flavorings and colorings

    • Give special qualities to food—changing the texture, for instance

Keeping your food supply safe
Keeping Your Food Supply Safe

  • The government has agencies like the Food and Drug Administration and the US Department of Health

  • The food industry provides information about food safety to consumers and gives consumer hotlines for problems and/or recalls


The world s food supply
The World’s Food Supply

  • With all this food, why are people still hungry?

    • Climate or geography makes it hard to grow foods in certain areas

    • Lack of transportation keeps people from getting food

    • Lack of fuel means you can’t cook the food you have

    • Natural disasters, like floods or storms may disrupt farming and/or transportation

    • Wars and political conflicts might prevent transportation of foods
