- 1.What is Food Biotechnology?
- Food biotechnology is theevolutionoftraditionalagricultural
techniques such as crossbreeding andfermentation .
- It is anextensionof the type of food development that has
providednectarines ,tangerinesand similaradvancements .
2. Technically Speaking...
- Food biotechnology employs the tools ofmoderngenetics toenhance
beneficialtraits of plants, animals and microorganisms for food
production.It involves adding or extracting select genes to achieve
desired traits.
3. 4. 5. The musical stylings ofDr. Karl Winters 6. There must
be more to it than that, Doc
- Must be a protein already in existence
- A Selectable Marker is required to identify the clone.
- The selectable marker is usually antibiotic resistance, which
does not make YOU antibiotic resistant.

types of biotechnology
- Random mutagenisis and selection (directed evolution)
9. Food Biotechnology Applications
- Biotechnology methods are currently used toimprovemany
foods.
- Food biotechnology has had aprofound positive impacton farming
and food security.
- At least twelve industrialized and four developing countries
currently use some form of food biotechnology.

-
- Delayed ripening allows fruits and vegetables to
remainfreshlonger
-
- Increased solids give foodssuperior taste
-
- and less water to remove for sauces.

-
- Some oils are lower in saturated fat and higher in oleic acid,
making them more stable for fryingwithout further processing .
-
- Some foods have lower levels of saturated fat.

- Some foods haveenhanced nutritional profiles .
-
- Biotechnology allows for the production of foods to helpprotect
against diseases .
-
- Enhancedfoods will soon offer higher levels of antioxidant
vitamins toreduce risk of cancer.Now being commercialized at
Rutgers! (black tea extract).

21. Consumers SupportFood Biotechnology
- Nearly two-thirds believe food biotechnology will benefit their
family in the next five years.
- More than half would choose products modified to taste better
or fresher.
- Two-thirds would likely buy produce protected against insect
damage.

22. Environmental Impact ofAgricultural Biotechnology
- Healthier plants result in higher yields.
- Insect-protected crops reduce the need for insecticides.
- Biotechnology helps protect water(less pesticide run off, less
erosion.)
23. Economic Impact ofAgricultural Biotechnology
- Food biotechnology results in higher plant yields, increasing
farmers efficiency.
- Farmer production costs are reduced.
- Debilitating plant diseases and insect pests are often
preventable.
24. Combating Hunger
- Food biotechnology allows more food to be produced on less
land.
- Economic benefits will allow food biotechnology to contribute
to combating global hunger.
25. Combating Hunger
- Food biotechnology allows more food to be produced on less
land.
- Economic benefits will allow food biotechnology to contribute
to combating global hunger.
26. Food BiotechnologyIs Safe
- Food biotechnology is one of the most extensively reviewed
agricultural advancements to date.
- Studies to date have shown no evidence of any harmful
effects.
FDA USDA AMA IFT FAO/ WHO ADA 27. What is the FDAsapproval
procedure ?
- Regulate the product, not the process.
- Regulate the ingredient, not its method of manufacture.
- Substances that are not GRAS or exempt will be regulated as
additives.
- Encourages informal consultation.
28. FDAs basic paradigm
- Is the gene coming from the donor well characterized?
- Is the vector (plasmid) well characterized?
- Is the recipient of the gene well characterized?
29. Potential Problems with GE Foods
- Antibiotic resistance (significance needs to be
determined)
- Introduction of new proteins into foods (FDA seeks
comments)
- Plants used to make nonfood substances.
- Special concerns with animal feeds.
- Unintended pleotropic effects
- Increases of known toxins, decreases in nutrients
- Activation of dormant pathways, allergens
30. 31. U.S. Labeling Policy forFood Biotechnology
- FDA safety standards are consistent for all foods.
-
- Must label the presence of common allergens not normally found
in certain foods
-
- Must demonstrate scientifically that allergens are not present
in modified food.
-
- If nutritional content or composition has been changed, product
must be labeled accordingly.
32. Consumers SupportLabeling Policy
- More than two-thirds of consumers support the FDA labeling
policy

33. What Does the Future Hold?
- Food biotechnology has the
- Reduce levels of natural toxins in plants
- Provide simpler and faster ways to locate pathogens, toxins and
contaminants
- Keep products fresher longer
- Identify ways to eliminate allergens from many foods
- Increase food supply to support growing world population and
decreasing agricultural space.
34. So whats the bottom line, Doc?
- It depends on the market.
- It depends on how you vote.
