Powdered milk has a far longer [[shelf life]] than liquid milk and does not need to be [[refrigeration|refrigerated]], due to its low moisture content. ==History== Powdered milk was first made in [[1802]] by Russian doctor [[Osip Krichevsky]]. It is found abundantly in many developing countries because of reduced transport and storage costs (reduced bulk and weight, no refrigerated vehicles). As with other dry foods, it is considered nonperishable and is favored by [[Survivalism|survivalists]], [[hiking|hikers]] and others needing of nonperishable, easy to prepare food. ==Processing== Powdered milk is typically made by [[spray drying]] nonfat [[skim milk]]. Whole milk powder can also be manufactured in a similar fashion. [[Pasteurization|Pasteurized]] milk is first concentrated in an [[evaporator]] to about 50% milk solids. The resulting concentrated milk is sprayed into a heated chamber where the water almost instantly evaporates, leaving fine particles of powdered milk solids. Alternatively, the milk can be dried by [[drum drying]]. Milk is applied as a thin film to the surface of a heated drum, and the dried milk solids are then scraped off. Powdered milk made this way tends to have a cooked flavor, due to [[caramelization]] caused by greater heat exposure. Another process is [[freeze drying]], which preserves many nutrients in milk, compared to drum drying. [http://nl.wikipedia.org/wiki/Vriesdrogen_%28conservering%29] The drying method and the heat treatment of the milk as it is processed alters the properties of the milk powder (for example, solubility in cold water, flavor, [[bulk density]]). ==Uses== Powdered milk is frequently used in baking, in recipes where adding liquid milk would render the product too thin to be used. It is also a common in [[World Food Programme|UN food aid]] supplies, [[fallout shelters]], warehouses and wherever fresh milk is not a viable option. Powdered milk is also used in [[Western blot]]s as a blocking agent to prevent nonspecific protein interactions.{{Fact|date=April 2007}} Reconstituting 1 cup of milk from powdered milk requires 1 cup of potable water and 1/3 cup of powdered milk. Powdered milk is also widely used in various sweets such as the famous Indian milk sweet balls known as ''gulab jamuns''. ==Controversy== Compared to fresh milk, powdered milk (and [[powdered eggs]]) are stated to be exceptionally high in oxysterols (oxidized cholesterol).<ref>[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=2678267&query_hl=2&itool=pubmed_docsum Atherogenic effect of oxidized products of cholest...[Prog Food Nutr Sci. 1989&#93; - PubMed Result<!-- Bot generated title -->]</ref> The [[free radical]]s have been stated to have [[atherogenic]] ("causing [[atherosclerosis]]")<ref>[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=2678267&query_hl=2&itool=pubmed_docsum Atherogenic effect of oxidized products of cholest...[Prog Food Nutr Sci. 1989&#93; - PubMed Result<!-- Bot generated title -->]</ref>.

He should not be confused with [[Powdered Toast Man]], a character from the animated [[The Ren and Stimpy Show|Ren and Stimpy Show]] on television. *Due to its resemblance to [[cocaine]], powdered milk is sometimes used in the movie industry as a prop in lieu of actual cocaine. *Powdered milk was also used on TV to create the piles of dust which were all that remained of (most of) the original [[Red Dwarf]] crew. ==References== <references/> ==See also== *[[Baked milk]] *[[Condensed milk]] *[[Evaporated milk]] *[[Scalded milk]] *[[Coconut milk powder]] [[Category:Granular materials]] [[Category:Milk]] [[Category:Dried foods]] [[Category:Dairy products]] [[de:Milchpulver]] [[es:Leche en polvo]] [[eo:Laktopulvoro]] [[fr:Lait en poudre]] [[id:Susu bubuk]] [[it:Latte in polvere]] [[lt:Pieno milteliai]] [[nl:Melkpoeder]] [[ja:粉ミルク]] [[pl:Mleko w proszku]] [[pt:Leite em pó]] [[ru:Сухое молоко]] [[simple:Milk powder]] [[sv:Mjölkpulver]] [[zh-yue:奶粉]] [[zh:奶粉]]
