Incredible Because: It toppled the Italian lemon industry and is used in the production of high fructose corn syrup
Industrial-scale citric acid production began in 1890 based on the Italian citrus fruit industry. But a mere 27 years later (in 1917,) the American food chemist James Currie discovered that certain strains of the mold Aspergillus niger could be efficient citric acid producers, and Pfizer began industrial-level production using this technique two years later, followed by Citrique Belge in 1929. This caused the toppling of the Italian citrus industry. Aspergillus niger is also used in the production of high fructose corn syrup (HFCS). In the United States, HFCS is typically used as a sugar substitute and is ubiquitous in processed foods and beverages, including soft drinks, yogurt, cookies, salad dressing and tomato soup.
