•Biscuit is a term used for a variety of baked, commonly flour-
based food products.
•Biscuit (Europe) = cookie or cracker (North America)
•In the Commonwealth Nations, "cookie" typically refers to
only chocolate chip cookie.
•In the United States and some parts of English Canada,
a "biscuit" is a quick bread, usually unsweetened.

Flavour development in biscuit
• Maillard reaction:
When protein (Gluten) and sugar(carbohydrates) in the biscuit
are heated it becomes brown, and that interaction produces
flavour. It is called Maillard reaction and this is the back bone
of the baking/cooking/roasting/ almost all the
cooking/baking.
• Caramelization or caramel flavour:
Sometimes Caramelization causes browning the same foods in
which the Maillard reaction occurs, but the two processes are
distinct. They are both promoted by heating, but the
Maillard reaction involves amino acids, as discussed above,
whereas caramelization is simply the pyrolysis of certain
sugars.
• Fats, oils, milk and milk products are also responsible for
imparting flavour in biscuits.
• Role:
 Tasteenhancer
 Masking any undesirable odour from theproduct
 It increases palatability and make product acceptable
 Provide identity
 Reduces raw material cost
 Make biscuits of consistent quality
• Selection:
 The flavour should be stable and non reactive with
the other ingredients
 Many flavours are heat susceptible and protection of
flavours needs consideration of baking process.
