The type of potato that is used in the manufacture of a food product is of extreme importance. Manufacturers need to know that the products they make are of a uniform and consistent quality.
Colour
Freshly peeled pr cut potatoes will start to discolour if exposed to air. This is due to the enzymic browning of the potato. Potatoes should be prepare as required or kept in cold water for short periods to prevent browning, If frozen products are to be produced, e.g. chips,the potato pieces need to be blanched in boiling water.
Functional Properties

Potatoes may be added to soups,stews and casseroles got thicken the mixture. Potato starch is used industrially to thicken instant dessert mixes and canned soups and in the manufacture of extruded snack.

Storage
Potatoes should be stored in dark,cool and dry conditions to prevent them sprouting,becoming mouldy and changing colour.
