What are the main ingredients in granola cereals?

Granola is an improvement over cereals made from refined grains. The major raw material used to make a granola cereal is rolled oats, either regular whole-rolled or quick-cooking oats.

Nuts pieces, coconut, brown sugar, honey, malt extract dried fruits, dried milk, water and vegetable oil are all mixed with the oats. Spices such as cinnamon and nutmeg can be also added. Mass produced crunchy granola bars are reasonably healthy, high density, high-energy food and some of the best things for hikers to carry when they do hiking.

Sugar content in granola cereals ranges from 22% to 32% of the dry weight of the cereals. When granola bars first arrived on the market they were a mixture of rolled oats, dried fruits, nuts, seeds, honey, some sugar and a variety of oils but they contained both protein and carbhydrates in sufficient quantity to be better for consumer than most candy bar.

Production of most granola bars involves no heat, other than heating the syrup. Some version of granola bars are dipped in a coating after extrusion. Typically this take place as the bars pass through an enrober, where liquid coating – chocolate, yogurt, carob and so on - is poured over them.
