Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products.

1. FoodTechnology Course
Lecture 1: Introduction to FoodTechnology

2. COURSE DESCRIPTION
The course introduce students to the
principles and technology in the food
industry. The course covers the
scientific methods of food processing
including the methods of thermal
processing, fermentation, dehydration
chilling and freezing and the use of
food additives. Also the course
examines the quality and legislation
aspects of food. The practical part of this
course comprises applications of some
processing methods on local foods.

3. COURSE OUTCOME
At the End of this course the student will :
Have comprehensive understanding of chemical, physical and
nutritional properties of major food constituents
Have deep understanding of the principles and recent trends in
food preservation, food processing techniques and able to process
some finished goods.
Choose the right method and equipment for the processing of the
various foods with the highest sensory, nutritional, and sanitary
quality for the longest possible time.
identify food safety hazards and develop a food safety program
such as HACCP.

Who is Food Technologist?

10. IMPORTANCE OF FOOD TECHNOLOGY
Extend shelf life of food – Preservation
Make better taste of Food
Ensure safe food and healthier food

11. ESSENTIAL COMPONENTS OF FOOD
Carbohydrates
Protein
Fats
Vitamins
Minerals
Water

12. FOOD PRESERVATION TECHNIQUES
Pasteurization
Fermentation
Drying
Salting
Curing
Canning/Aseptic Food
Irradiation and more

13. PASTEURIZATION
The heating of milk
and other liquids
which reduces the
number of disease
producing bacteria.

14. FERMENTATION
The use of special
bacteria, molds or yeasts
to prevent spoilage by
converting the elements
of food to
stable elements that act
as preservatives.

15. DRYING
Extraction of moisture
by sun, air, heat or
vacuum to inhibit the
growth of molds,
bacteria and yeasts

16. SALTING
The addition of salt
or a brine solution
to
foods to decrease
the activity of molds,
bacteria and yeasts.

17. CURING
The addition of a
chemical compound
(sodium nitrate or
sodium nitrite) to food
to slow the growth of
bacteria.

18. CANNING/ASEPTIC
PACKAGING
The packing of food
in a container,
sealing the container
and heating it to
sterilize the food.
