Det finns en envis myt kring mikrov\u00e5gsugnar – att de f\u00f6rst\u00f6r n\u00e4ringen i maten. Att v\u00e4rma p\u00e5 annat s\u00e4tt, till exempel p\u00e5 spisen, skulle vara skonsammare. Enligt en unders\u00f6kning som gjorts av Konsumentf\u00f6reningen Stockholm tror en tredjedel av alla svenskar att s\u00e5 \u00e4r fallet.<\/p>\n
F\u00f6r mig, som i botten \u00e4r fysiker, \u00e4r detta helt obegripligt. Vad som h\u00e4nder i ugnen \u00e4r att mikrov\u00e5gorna \u201dboxar till\u201d vattenmolekylerna s\u00e5 att de b\u00f6rjar vibrera, de blir varma. Vid annan uppv\u00e4rmning blir konsekvenserna desamma, molekylerna b\u00f6rjar vibrera.<\/p>\n
Att jag tar upp saken beror p\u00e5 att jag l\u00e4st en artikel p\u00e5 R\u00e5d & R\u00f6n. De ber\u00e4ttar<\/a> att myten sprids vidare genom boken D\u00f6den i grytan, av Mats-Eric Nilsson och Henrik Ennart.<\/p>\n De refererar till en forskningsartikel d\u00e4r forskarna hade mikrat 10 gram k\u00f6tt i fem minuter p\u00e5 500 W, och kommit fram att det inte fanns n\u00e5got vitamin B12 kvar.<\/p>\n Enligt boken skulle detta visa att mikrov\u00e5gsuppv\u00e4rmning p\u00e5verkar n\u00e4ringsinneh\u00e5llet negativt. Det \u00e4r snarare f\u00f6rv\u00e5nansv\u00e4rt att n\u00e5got fanns kvar av ursprungsmaterialet n\u00e4r man v\u00e4rmer en s\u00e5dan liten m\u00e4ngd s\u00e5 l\u00e4nge. Resultatet hade blivit detsamma p\u00e5 en vanlig spis, n\u00e5got som Nilsson och Ennart inte verkar ha funderat \u00f6ver. F\u00f6rs\u00f6ket visar bara att k\u00f6tt f\u00f6rlorar n\u00e4rings\u00e4mnen vid extremt l\u00e5ng uppv\u00e4rmning, olika metoder j\u00e4mf\u00f6rs inte.<\/p>\n Det finns inget som tyder p\u00e5 att mikrov\u00e5gsuppv\u00e4rmning skulle minska halten n\u00e4rings\u00e4mnen i maten, j\u00e4mf\u00f6rt med andra metoder, snarare tv\u00e4rt om. Vid mikrov\u00e5gsuppv\u00e4rmning anv\u00e4nds lite, eller inget, vatten. Det skulle kunna leda till att vattenl\u00f6sliga n\u00e4rings\u00e4mnen, till exempel vitamin B och C, bevaras i h\u00f6gre grad.<\/p>\n Andra bloggar om: Mikrov\u00e5gor<\/a>, Mikrov\u00e5gsugn<\/a>, N\u00e4ring<\/a>, N\u00e4rings\u00e4mnen<\/a>, Vitaminer<\/a>, D\u00f6den i grytan<\/a>, Mats-Eric Nilsson<\/a>, Henrik Ennart<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Det finns en envis myt kring mikrov\u00e5gsugnar – att de f\u00f6rst\u00f6r n\u00e4ringen i maten.
