Transcript and Presenter's Notes

Title: Additives may be...........


1
Additives
  • Additives may be...........
  • Natural - beetroot juice as a red colouring
  • Chemical made by scientists such as aspartame
  • Synthetic-have the same chemical structure as a
    natural additive but made in a laboratory.

2
E numbers
  • The E number indicates that an additive has
    passed the European Community Safety Standards.
  • The E number is a code used instead of a long
    chemical name so for example pentasodium
    triphosphate is known as E451.

3
Colours
  • Colours
  • E100s such as drinks icings

4
Preservatives
  • Preservatives
  • E200s which extends shelf life, in sausages and
    canned meats

5
Emulsifiers and stabilisers
  • Emsulsifiers and stabilisers
  • E400s such as lecithin which lets oil and water
    mix such as in an ice cream. Stabilisers stop
    ingredients separating such as in sauces.

6
Antioxidants
  • Antioxidants
  • E300s prevent oxidation of fats and slow down the
    enzymic browning of fruit and vegetables.

7
Gelling agents
  • Are used to set jams and change the consistency
    of some sweets.

8
Flavour enhancers
  • Flavour enhancers
  • E600s make natural flavours stronger often used
    in soups and snacks.

9
flavourings
  • Which include herbs and spices such as parsley,
    cinnamon and vanilla are natural flavourings
  • Flavourings which do not have an E number. They
    are shown as flavouring such as strawberry
    flavouring in a cold dessert.

10
Sweetners
  • These have fewer calories than natural sugar.
    Some are intense sweetners such as aspartame.
    Used in fizzy drinks.

11
Thickners
  • Used to thicken liquids

12
Anti-caking agents
  • Used to prevent dry ingredients sticking together

13
Hyperactivity
  • Some consumers do not eat food with chemical and
    synthetic additives as a life choice.
    Hyperactivity in children has been linked to food
    colouring. Such as tartrazine.
