margarine: [19] Margarine was invented in 1869 by the French food technologist Hippolyte Mège-Mouries. Its name was based on margaric acid, a term coined by the French biochemist Michel-Eugène Chevreul for a fatty acid which he believed to be one of the constituents of animal fats (the earliest margarine was made from clarified beef fat). He derived it from Greek margarítēs ‘pearl’ (source also of English marguerite [19], and of the names Margaret and Margot), an allusion to the pearly lustre of the acid crystals. The abbreviation marge dates from the 1920s. => marguerite[margarine etymology, margarine origin, 英语词源]
