Bakery products are consumed all over the world. Fat is an
important ingredient in bakery products and its major functions
are to tenderise the product and soften the texture, add moistness
and richness, increase keeping quality, add flavour, and to assist in
leavening when used as creaming agents or when used to give flakiness
to puff pastry, pie, dough, and similar products. However, fat has a disadvantage of getting oxidised rapidly
upon exposure to air, moisture, and sunlight, giving rise to an
unacceptable flavour.
