FOOD BIOTECHNOLOGY AND FOOD SAFETY.pptx

slide describes different aspects of food biotehnology.

1. PERSPECTIVES OF FOOD BIOTECNOLOGY

2. Contents… Introduction How it function Consumer benefits of food biotechnology How nutrients regulate genes Consumer support Impacts of Agricultural Biotechnology Types of biotechnology Applications of food biotechnology Conclusion

3. What is Food Biotechnology ??? Food biotechnology is the evolution of traditional agricultural techniques such as cross breeding and fermentation.

4. Generally in biotechnology ..... transcription translation 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 .

5. 2. How it functions .....

6. Food Biotechnology …………… Biotechnology methods are currently used to improve many foods Food biotechnology has a preferred positive impact on farming and food security. At least 12 industrialized and four developing countries currently using some form of food biotechnology.

7. 3. Consumer benefits of food biotechnology Taste and quality - Delayed ripening allows fruits and vegetables to remain fresh longer. - Increased solid give food superior taste and less water content.

8. Nutrition - Some oils 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.

9. 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.

10. 4. How nutrients regulate genes Nutrients Gene impact Disease potential Folic Acid DNA methylation Cancer Fatty Acids Bind to transcription factors Obesity Vitamin – D m-RNA Stability Kidney Diseases Flavones Increase mRNA synthesis Cancer T henflavions Decrease mRNA synthesis Artheritis Wellgen , is the first Biotech company using nutrigenomics to discover and develop proprietary products that treat and prevent diseases

11. 5. Consumers Support Nearly two-thirds believe that biotech will benefit their family in the next five years. More than half world choose products modified to taste better or fresher. Two-third would likely to buy produce protected against insect damage.

12. 6. Environmental impact of Agricultural Biotechnology Healthier Plants results in higher yields. Insect protected crops reduce the need for pesticides. Biotechnology helps protect water (less pesticide runoff , less erosion)

13. Economic impact of Agricultural biotechnology Food Biotechnology, results in higher plant yields, increasing farmer’s efficiency. Farmer‘s production costs are reduced. Debilitating plant diseases and insect pests are often preventable.

14. 7. Other types of biotechnology Clonal propagation Random mutagenesis and selection (directed evolution) Metabolic redirection Use of “xenophiles ”.

15. 8. Food 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 using some form of food biotechnology.

16. 9. Conclusion Food Biotech has the potential to : - Reduce levels of natural toxins in plants. - Provide simpler and faster way to locate pathogens, toxins and contaminants. - keep products fresh longer. - identify ways to eliminate allergens from many foods. - increase food supply to support growing world population and decrease agricultural space.
