Peanut butter is a nutrient-rich food containing high levels of protein, several vitamins, and dietary minerals.

[citation needed] A businessman from St. Louis named George Bayle produced and sold peanut butter in the form of a snack food in 1894.

[6] John Harvey Kellogg, known for his line of prepared breakfast cereals, was an advocate of using plant foods as a healthier dietary choice than meat.

[6][7][8] Kellogg's Western Health Reform Institute served peanut butter to patients because they needed a food that contained a large amount of protein that could be eaten without chewing.

[5][6] At first, peanut butter was a food for wealthy people, as it became popular initially as a product served at expensive health care institutes.

[14][13] In 1922, chemist Joseph L. Rosefield invented a process for making smooth peanut butter that kept the oil from separating by using partially hydrogenated oil; Rosefield licensed his invention to the company that created Peter Pan peanut butter in 1928.

[14] Under the Skippy brand, Rosefield developed a new method of churning creamy peanut butter, giving it a smoother consistency.

[5] In 1955, Procter & Gamble launched a peanut butter named Jif, which was sweeter than other brands due to the use of sugar and molasses in its recipe.

[5] In South Africa, the first peanut butter was produced in 1926 by Alderton Limited in Potgietersrus (now Mokopane),[15] The product proved so popular that Tiger Brands (then Tiger Oats Company) took over the manufacture under the brand name Black Cat, which it still produces.

Butter is a dairy product usually made from cow's milk and processed into a solid that can be spread on food.

The moisture of the unshelled peanuts is controlled to avoid excessive frangibility of the shells and kernels, reducing the dust in the plant.

[25] There are suction fans in the metal cylinder that can pull a large volume of air through,[27] so the peanuts can be cooled more efficiently.

While the skins are removed, the kernels are brought through a one-minute hot water bath and placed on a swinging pad with canvas on top.

[25] At this point, salt, sugar, and vegetable oil stabilizer may be added to the fine grind; this adds flavor and allows the peanut butter to stay as a homogeneous mixture.

The peanut butter jars are then packaged into cartons and distributed to retailers, where they are stored at room temperature and sold to consumers.

[34] In a 100 gram amount, smooth peanut butter supplies 597 calories and is composed of 51% fat, 22% protein, 22% carbohydrates (including 5% dietary fiber), and 1% water (table).

Also high in content are the dietary minerals manganese, magnesium, phosphorus, zinc, copper, and sodium (added as salt during manufacturing).

Peanut butter is a moderate source (10–19% DV) of thiamin, riboflavin, iron, and potassium (table).

The creamy or crunchy, fatty, salty taste pairs very well with complementary soft and sweet ingredients like fruit preserves, bananas, apples, and honey.

The groove in the celery stick is filled with peanut butter and raisins arranged in a row along the top are "ants".

A single pack contains 500 calories, can be stored unrefrigerated for two years, and requires no cooking or preparation.

[42] Peanut butter inside a hollow chew toy is a method to occupy a dog with a flavored treat.
