Cereal germ

 ( Cereals ) 

The germ of a cereal is the part that develops into a plant;

it is the seed embryo. Along with bran, germ is often a by-product of the milling

may be used as a source from which vegetable oil is extracted, or used directly as a food ingredient. The germ is retained as an integral part of whole grain foods.

Non-whole grain methods of milling are intended to isolate the endosperm, which is ground into flour, with removal of both the husk (bran) and the germ. Removal of bran produces a flour with a white rather than a brown color and eliminates fiber. The germ is rich in polyunsaturated fats (which have a tendency to oxidize and become rancid on storage) and so germ removal improves the storage qualities of flour.

Some manufacturers prevent rancidity by storing wheat germ in vacuum-sealed glass containers, or by placing an oxygen absorber sachet inside air-tight packaging.

Other uses In molecular biology, wheat germ extract is used to carry out Cell-free system in vitro translation experiments: the plant embryo contains all the macromolecular components necessary for translating mRNA into , but relatively low levels of its own mRNA.

Wheat germ is also useful in biochemistry since it contains lectins that bind strongly to certain glycoproteins; therefore, it can be used to isolate such proteins.
