Shredded wheat  Shredded wheat is a breakfast cereal made from whole wheat formed into pillow-shaped biscuits. It is commonly available in three sizes: bite-sized (¾×1 in), miniature (nearly half the size of the bite-sized pieces), and original. Both smaller sizes are available in a frosted variety, which has one side coated with sugar and usually gelatin. Some manufacturers have produced "filled" versions of the bite-size cereal containing a raisin at the center, or apricot, blueberry, raspberry, cherry, cranberry or golden syrup filling. In the United States, shredded wheat is most heavily advertised and marketed by Post Foods, which acquired the product in 1993 through its parent company, Kraft Foods, buying it from its long-time producer Nabisco. Kellogg's sells eight varieties of miniature, or bite-sized, shredded wheat cereal. Natural and organic manufacturer Barbara's Bakery makes an all-natural version of shredded wheat. In the United Kingdom, the Shredded Wheat brand is owned by Cereal Partners, a Nestlé/General Mills company, although there are many generic versions and variants by different names. It was first made in the United States in 1893, while UK production began in 1926. Henry Perky invented shredded wheat cereal in Denver, Colorado, in 1890, as well as founding the Cereal Machine Company. In 1895, Perky received United States Patent Number 548,086, dated 15 October 1895. The biscuits proved more popular than the machines, so Perky moved East and opened his first bakery in Boston, Massachusetts and then in Worcester, Massachusetts in 1895, retaining the name of The Cereal Machine Company, and adding the name of the Shredded Wheat Company. Inspired by his observation of a dyspeptic diner blending wheat with cream, he developed a method of processing wheat into strips that were formed into pillow-like biscuits. The wheat is first cooked in water until its moisture content reaches about 50%. It is then "tempered", allowing moisture to diffuse evenly into the grain. The grain then passes through a set of rollers with grooves in one side, yielding a web of shredded wheat strands. Many webs are stacked together, and this moist stack of strands is crimped at regular intervals to produce individual pieces of cereal with the strands attached at each end. These then go into an oven, where they are baked until their moisture content is reduced to 5%. Perky first sold his shredded wheat cereal to vegetarian restaurants in 1892, distributing it from a factory in Niagara Falls, New York.
