The main objectives in food industry

Essentiality of water in life

Hydrogen bonds and other weak interactions in biomolecules

molecules (biological systems)/long-range hydrophobic

interactions

Biological systems perform various kinds of work

Thermodynamics and biochemists

Page 4: Food Chemistry and Biochenmistry of Foods Dr. F. Vahabzadeh.

Water activity/sorption isotherms/hygroscopic and non-

hygroscopic foods

Langmuir theory and equation/BET equation/sorption hysteresis

Carbohydrates/photosynthesis

Page 5: Food Chemistry and Biochenmistry of Foods Dr. F. Vahabzadeh.

Proteins

Enzymes and enzymatic reactions/(kinetics of enzyme-catalyzed

reaction)

The kinetics of the reactions leading to deterioration of foods/loss

of food quality and nutritional value as a function of the reaction

conditions changes in the foods and the external environment

Enzymatic browning/non-enzymatic browning/Black tea

manufacture

Page 6: Food Chemistry and Biochenmistry of Foods Dr. F. Vahabzadeh.

Fermentation process/Energy generation in biological

systems(bioenergetics)/Glycolysis and citric acid cycle/

Electron-transport chain/Oxidative reactions/Mechanism of ATP

formation

Page 7: Food Chemistry and Biochenmistry of Foods Dr. F. Vahabzadeh.

Lipids/fats and oils

Theories of triacylglycerol distribution pattern

Lipid auto-oxidation/Mechanism/Kinetics/pro-oxidant and

anti-oxidant

Lipase enzymes/Hydrolytic reactions of lipids/formation of

mono-and di-acylglycerols Transesterification reaction of

triacylglycerol/ biodiesle formation (enzymatic and non-

enzymatic)
