Aluminiumsfolie - Denne siden opp?

[medlem-68510]

Litt merkelig spørsmål fra meg denne julekvelden, men hvilken side av aluminiumsfolien skal være mot maten? Den er jo blank på den ene siden, og matt på den andre

[perpyro]

Den blanke siden skal ned mot maten for å reflektere varmen innover mot maten.

Mange takk. Jeg tenke det samme =)

Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is nearly impossible to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the shiny side's reflective properties keep heat out when wrapped on the exterior and keep heat in when facing exterior, the actual difference is imperceptible without instrumentation. The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.
