  1. Contaminants in food and beverages Contamination in food oil (Edible Oil) Presented by: Pooja S. Dandekar T.Y. B.sc (Chemistry)

  2. Contents • Types of oil • Sunflower oil and its contaminants • Risk factors of contamination (Sunflower oil) • Fish oil and its contaminants • Side effects of the contamination • Benefits of Fish oil • Remedies to reduce contamination (Fish oil)

  3. Types of oil • Oil is a collective term for more or less viscous, generally organic chemical liquid depending on their chemical composition a distinction may be drawn between: • Fatty oil • Essential oil • Mineral oil • Silicone oil Note: Fatty oil is also known as sweet oil.

  4. Sunflower oil and its contaminants • It is vegetable origin. • High quality edible oil. • Obtained from fatty kernels of sunflower Types of Sunflower oil • Cold pressed crude oil (color: Light yellow) • Hot pressed crude oil (color: Brown) • Refined oil (colorless)

  5. Contaminants of sunflower oil • Acid value • 0.9 -1.1 % • Rancidity • Promoted by light, atmospheric oxygen, moisture • Ferrous and rust particles • Sea Water • Unshelled kernels • Packaging • Transport • Cargo handling

  6. Risk factors of contamination (Sunflower oil) • RF temperature • RF moisture • RF Ventilation • RF Gases • RF Contamination behavior • RF Shrinkage / Shortage

  7. Salmon and cod liver oil and their contaminants • 23% consumption rate in 1987 – 99 • Omega 3 – fatty acid present in salmon • Fish farm pesticides • Flame retardants • PBDE (poly brominated diphenyl ether )

  8. Omega 3 fatty acid structure

  9. Side effects of the contamination • Size and shape of a Fish may change • May risk of cancer • Salmon feeding

  10. Benefits of Fish oil • Reduces heart deceases • Lowers the risk of cancer • Chronic deceases such as: • Asthma • Depression • High blood pressure • Rheumatoid Arthritis

  11. Remedies to reduce contamination (Fish oil) • Molecular distillation • Use of air-tight containers for storage.
