Rice germ in dog food
Before processing, rice grains are made up of four parts: the hard outer hull, the inner seed coat or pericarp, the starchy endosperm (which goes on to make white rice) and the embryo or germ. The germ is a fairly insubstantial part of the whole grain, comprising only about 2% of the whole, but it is this tiny bud that would grow into a new rice plant, using the endosperm as its food source.
Despite it's small size, the germ contains a very large proportion of the rice grain's vitamins and is very rich in several B vitamins, particularly thiamine.
Rice bran is made up of the pericarp and the germ.
