5-CONCLUSION

4. 1-INTRODUCTION:
Food is a vital element for every human.the need for something
to eat, breathe and drink is the main requirement to survive.
The human body is made out of cells,wich needs nutrients to
function. food provide energy that’s necessary for the body to do all
the activities: walking, talking…..

5. any substance
containing nutrients , such
as carbohydrates, proteins,
and fats, that can be ingested by
a living organism
and metabolized into energy and
body tissue
Food is an edible substance that
comes from animals or plants and
can be assimilated by an organism
to produce energy , stimulate
growth and maintain life.

6. FOOD INTAKE
35kcal/kg/day

7. • Biotechnolgy =
• bios (life)+ techno (tools) + logos (study of)
The study of tools from living things.
• It’s any technological application that use biological
systems,living organisms(or parts of living organisms)to
make, modify, impove plants or animals for benificial
use.

9. Available definations of biotechnology:
• Biotechnology is the application of biological organisms systems
or process to manufacturing and servise industries.(British
biotechnologists)
• Biotecnhology is integraed use of biochemestry,microbiology and
engineering sciences in order to achieve technological application
of microbes, cultured cells and parts there of (European
federation of biotechnologists)
• Biotechnology is the controlled use of biological agents, such as
microbes or cellular components.(U.S.Nationel science
foundation)

10. BIOTECHNOLOGYAPPLICATIONS:
Medical and pharmaceutical biotechnology:
Antibiotics
Vaccines
Humain hormones
(insulin)
Tissue engineering
Stem cells
Cancer therapies

11. Environemental biotechnology:
• Biofuel, biodiesel , biogas
Use bacteria and some plants to clean up
environmental wastes

12. 4-FOOD BIOTECHNOLOGY:
• Food biotechnology is the application of technologies
to make or modify animals, plants, and
microorganisms, which have desired production,
marketing, or nutrition related properties to obtein
food.

13. FOOD BIOTECHNOLOGYAPPLICATIONS:
• Plant agriculture:
• Increased production
• Cross breeding
• Herbicide or pesticide resistant plants
• The use soil bacteria « Bacillusthurigiensis»as an insecticide

15. Animal agriculture:
Reproduction, selection andbreeding,
animal health,
Feedingand nutrition,
Growth and production.

16. Food processing:
• The use of bacteries:
• Saccharomyces cerviceae to make bread
• Lactobacillus to produce yogort
• Fangi to produce chees

17. Food processing:
Extended shelf life
Efficient food processing
Better nutrients composition

18. TransgenicsGMO
• Transgenic are genetically modified organisms with
DNA from another source inserted into their genome
Genes from other species/organisms. Organisms that
have transgenes are called genetically modified
organisms. As their genome is modified .to obteined
caeactred desired.

19. Transgenic animals: agriculture use
• chicken
• Salmon
• Beef

20. Industries and medicinal use

• Cancer
• Infertility
• Affect immune system, kidnyes ,digestif
system, liver
• higher blood sugar
• Accelerate aging
