Presentation Transcript

  1. Food Chemistry and Biochenmistry of Foods Dr. F. Vahabzadeh

  2. 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

  3. Water activity/sorption isotherms/hygroscopic and non-hygroscopic foods Langmuir theory and equation/BET equation/sorption hysteresis Carbohydrates/photosynthesis

  4. 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

  5. Fermentation process/Energy generation in biological systems(bioenergetics)/Glycolysis and citric acid cycle/ Electron-transport chain/Oxidative reactions/Mechanism of ATP formation

  6. 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)
