Butterfat

Butterfat or milkfat is the fatty portion of milk. Milk and cream are often sold according to the amount of butterfat they contain.

Composition

The fatty acids of butterfat are typically composed as follows (by mass fraction):

Fatty acids vs triglycerides

As shown above, the composition of fats in milk is usually discussed in terms of the fatty acids. Fatty acids do not occur as such in milk (and rarely in any food). Instead, they are incorporated into compounds called triglycerides.

Peanut butter

Peanut butter, popular in many countries, is a food paste made primarily from ground dry roasted peanuts. Some varieties contain added salt, seed oils, emulsifiers, and sugar, whereas "natural" types of peanut butter consist solely of ground peanuts. It is mainly used as a sandwich spread, sometimes in combination with other spreads such as jam, honey, chocolate (in various forms), vegetables or cheese. The United States is a leading exporter of peanut butter and consumes $800 million worth annually. Nuts are also prepared comparably as nut butters.

History

Peanut butter dates back to the Aztecs and the Incas.

Canadian Marcellus Gilmore Edson (February 7, 1849 – March 6, 1940) of Montreal, Quebec was the first to patent peanut butter, in 1884. Peanut flour already existed. His cooled product had "a consistency like that of butter, lard, or ointment" according to his patent application. He included the mixing of sugar into the paste so as to harden its consistency.

Edson, a chemist (pharmacist), developed the idea of peanut paste as a delicious and nutritious staple for people who could hardly chew on solid food, a not uncommon state back in those days. Peanut paste was initially sold for six cents per pound.

David Sanborn

David Sanborn (born July 30, 1945) is an American alto saxophonist. Though Sanborn has worked in many genres, his solo recordings typically blend jazz with instrumental pop and R&B. He released his first solo album Taking Off in 1975, but has been playing the saxophone since before he was in high school. Sanborn has also worked extensively as a session musician, notably on David Bowie's Young Americans (1975).

One of the most commercially successful American saxophonists to earn prominence since the 1980s, Sanborn is described by critic Scott Yannow as "the most influential saxophonist on pop, R&B, and crossover players of the past 20 years." Sanborn is often identified with radio-friendly smooth jazz. However, Sanborn has expressed a disinclination for both the genre itself and his association with it.

In his three-and-a-half-decade career, Sanborn has released 24 albums, won six Grammy Awards and has had eight gold albums and one platinum album. He continues to be one of the most highly active musicians of his genre, with over 150 tour dates in 2010.
