Title: What is Food Biotechnology?
1What is Food Biotechnology?
- Food biotechnology is the evolution of
traditional agricultural techniques such as
crossbreeding and fermentation. - It is an extension of the type of food
development that has provided nectarines,
tangerines and similar advancements. -
2Technically Speaking...
- Food biotechnology employs the tools of modern
genetics to enhance beneficial traits of plants,
animals and microorganisms for food production.
It involves adding or extracting select genes to
achieve desired traits. -

6There must be more to it than that, Doc
translation
transcription
- DNA makes RNA makes PROTEIN
- 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.
7And how do they do that?
8Other types of biotechnology
- Clonal propagation
- Random mutagenisis and selection (directed
evolution) - Metabolic redirection
- Use of xenophiles
9Food Biotechnology Applications
- Biotechnology methods are currently used to
improve many foods. - Food biotechnology has had a profound positive
impact on farming and food security. - At least twelve industrialized and four
developing countries currently use some form of
food biotechnology.

14The Colbert Report
- Many people get their information from (fake)
news.
15- Taste and Quality
- Delayed ripening allows fruits and vegetables to
remain fresh longer - Flavorsavar.
- Increased solids give foods superior taste
- and less water to remove for sauces.
16- Nutrition
- Some oils are lower in saturated fat and higher
in oleic acid, making them more stable for frying
without further processing. - Some foods have lower levels of saturated fat.
17J. Amer. Dietetic Assoc.,2006106285-293
18- Health
- Some foods have enhanced nutritional profiles.
- Biotechnology allows for the production of foods
to help protect against diseases. - Enhanced foods will soon offer higher levels of
antioxidant vitamins to reduce risk of cancer.

19How Nutrients Regulate Genes
20- WellGen, Inc.
- is the first biotechnology company using
nutrigenomics to discover and develop proprietary
products that treat and prevent disease -
- Nutrigenomics addresses
- the role of diet in gene expression
21Consumers Support Food 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. - Source Wirthlin Worldwide, October 1999
22Environmental Impact of Agricultural
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.)
23Economic Impact of Agricultural 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.
24Combating Hunger
- Food biotechnology allows more food to be
produced on less land. - Economic benefits will allow food biotechnology
to contribute to combating global hunger.
25Combating Hunger
- Food biotechnology allows more food to be
produced on less land. - Economic benefits will allow food biotechnology
to contribute to combating global hunger.
26Food Biotechnology Is Safe
FDA USDA AMA IFT FAO/WHO ADA
- Food biotechnology is one of the most extensively
reviewed agricultural advancements to date. - Studies to date have shown no evidence of any
harmful effects.
27What is the FDAs approval 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.
28FDAs 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?
29Potential 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

31U.S. Labeling Policy for Food 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.
32Consumers Support Labeling Policy
- More than two-thirds of consumers support the FDA
labeling policy - Source Wirthlin Worldwide, October 1999
33What Does the Future Hold?
- Food biotechnology has the
- potential to
- 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.
34So whats the bottom line, Doc?
- It depends on the use.
- It depends on the market.
- It depends on how you vote.
