2
Relate technological advances to their impact on food production and availability Compare the potential positive impacts of genetically modified foods Explain how science and technology have led to improved nutrition Assess the usefulness of technology in meal preparation
3
Analogs Aseptic Packages Clone Enrichment Ergonomics Food Science Formed Products Fortification Functional Foods Genetic Engineering Manufactured Food MAP Packaging Retort Pouches Science Technology
4
Science – the study of the physical world at all levels Technology – the practical application of scientific knowledge Food Science – scientific study of food and its preparation
5
Food production – › It is quicker and more efficient now to produce food with newer equipment. Tracters, GPS, fertilizers, pesticides, irrigation, immunizations Food processing – › New food choices › Packaging › Transportation
6
Manufactured food – a product developed as a substitute for another food. › Analogs – foods made to imitate actual foods › Formed Products – foods made from an inexpensive source and processed to imitate a more expensive food › Egg Substitutes – made from egg white and other ingredients
7
Modified atmosphere packaging (MAP)– mixture of carbon dioxide, oxygen, and nitrogen is inserted into the package before sealing to slow bacterial growth Aseptic packages – consist of layers of plastic, paperboard, and aluminum foil Retort pouches – flexible packages also made of aluminum foil and plastic film
8
Transportation and packaging combine to bring you food from around the world We can eat fresh food from different parts of the world that we would normally not be able to eat in certain climates
9
Genes are removed from one organism, such as a plant, animal, or microorganism, and transferred to another one
10
Larger food supply Improved nutrition Greater resistance to spoilage Reduced use of pesticides New and better varieties of food
11
Possible health problems, such as allergic reactions Potential threat to the environment and food supply Creation of super weeds that resist herbicides Inability of developing countries to buy the very expensive seeds
12
Clone – genetic copy of an organism Could prevent hunger as populations increase Could destroy the biodiversity of an animal
13
Enrichment – restores nutrients that were lost in processing to near original levels Fortification – adds a nutrient that is not normally found in a food
14
Functional Foods – provide health benefits beyond basic nutrition. › Natural whole foods – grapes, broccoli, salmon, garlic, oats › Enhanced foods – a cereal with added fiber › New food products – scientists continue to develop new foods with particular health benefits. Example – margarine that lowers cholesterol. › Food created by science – scientists create foods with special functions – tomato that lowers risk of cancer
15
Research has found 40 nutrients and hundreds of chemical compounds, all essential to good health
16
Ergonomics – study of ways to make space and equipment easier and more comfortable to use
17
Cooking Techniques – recipe is a chemical formula Appliances – food processers, mixers, stoves, refrigerators..... Personal Computers – shop, plan, and prepare meals. Get recipes and shop for the best deals
