Pre-cooked flours are fast dissolving or instant cereal-based preparations that, when rehydrated (with water or milk), provide a soup, mush, cream or dough. They are widely used as cereal-based baby foods (for children above four months) and, in many countries, they are used as ingredients in regional recipes. They are easy to store, to transport and to prepare and are balanced nutritionally.
Clextral twin-screw extrusion systems are ideal for processing perfectly formulated instant flours with all the required features: protein solubility, sensitivity of amylases to starches, bioavailability of minerals, etc.
A recipe for growth
Various cereals can be used to process pre-cooked flours: rice, corn, wheat, barley, oats, tapioca, manioc, etc. Local cereals or root vegetables can also be used. Recipes can include other ingredients such as milk powder, sugars, minerals and vitamins, as well as salt and flavours. For children, rice flour is often used in pre-cooked flours because it is easily digested, well balanced and low in allergens.
For adults, pre-cooked flours often use soy because of their high protein content or corn to make regional dishes: arepas in Colombia, Venezuela and Central America; gorditas in Mexico; and mingau in Brazil. These products can be served in soups or porridges, and vegetables, cheese and other ingredients can be added to prepare more elaborate dishes.
