Study Type		In Vitro
Model		2450 MHz (CW) exposure to milk and analysis of protein changes
Details		Whole and skim milk samples were heated with 2450 MHz (CW) in a conventional microwave oven to determine if exposure could isomerize and racemize amino acids in milk proteins, specifically in infant formulae causing toxicity or affecting nutritional value. Both microwaves and non-MW heating induced less than 0.25% additional racemization as compared to control samples. The authors conclude no significant effect of microwaves on milk protein changes.
Findings		No Effects (even at thermal levels)
Status		Completed With Publication

Comments		In contrast to this report, Lubec et al. (Lancet (1989) 2:1392-1393) reported MW exposure to milk did significantly racemize L-proline to D-proline and converted trans-hydroxyproline to cis-hydroxyproline.
