Robert Mumford Smock (October 21, 1908 – April 22, 1986) was an American scientist and a professor at Cornell University. Known for his research for over two decades in the field of controlled atmosphere, which led to the use of controlled atmosphere rooms in the United States in the 1950s and later throughout the world. The method he developed made it possible to extend the shelf life of fruits, especially apples throughout the year. Biography Smock was born in 1908 in Erie, Pennsylvania, to his father Grant Hibberd Smock, a dentist and his mother Frances Gibson Smock, a housewife the fifth of six brothers and sisters.

Diphenylamine
Diphenylamine is an organic compound with the formula (C6H5)2NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities.P. F. Vogt, J. J. Gerulis, "Amines, Aromatic" in Ullmann’s Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. Diphenylamine dissolves well in many common organic solvents, and is moderately soluble in water. It is used mainly for its antioxidant properties. Diphenylamine is widely used as an industrial antioxidant, dye mordant and reagent and is also employed in agriculture as a fungicide and antihelmintic. Preparation and reactivity Diphenylamine is manufactured by the thermal deamination of aniline over oxide catalysts: : 2 C6H5NH2 → (C6H5)2NH + NH3 It is a weak base, with a ''K''b of 10−14. With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate C6H5)2NH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ethoxyquin
Ethoxyquin (EMQ) is a quinoline-based antioxidant used as a food preservative in certain countries and originally to control scald on pears after harvest (under commercial names such as "Stop-Scald"). It is used as a preservative in some pet foods to slow the development of rancidity of fats. Ethoxyquin is also used in some spices to prevent color loss due to oxidation of the natural carotenoid pigments. Regulation Ethoxyquin was developed by Monsanto in the 1950s. Ethoxyquin was initially registered as a pesticide in 1965 as an antioxidant used as a deterrent of scald in pears through post-harvest indoor application via a drench and/or impregnated wrap.

McIntosh (apple)
The McIntosh ( ), McIntosh Red, or colloquially the Mac, is an apple cultivar, the national apple of Canada. The fruit has red and green skin, a tart flavour, and tender white flesh, which ripens in late September. In the 20th century it was the most popular cultivar in Eastern Canada and New England, and is considered an all-purpose apple, suitable both for cooking and eating raw.

He and his wife cultivated it, and the family started grafting the tree and selling the fruit in 1835. In 1870, it entered commercial production, and became common in northeastern North America after 1900. While still important in production, the fruit's popularity fell in the early 21st century in the face of competition from varieties such as the Gala.
