I was just coming here to post and report my findings! LOL!
Through research (including the above articles), I discovered that the best method for scalding is the the stove top. HOWEVER, if a stove top is unavailable, microwaving is an option.
Since microwaving destroys immunilogical properties and possibly some of the nutrition in ebm, it's best to do so only if absolutely neccessary. This wouldn't be a good method to use if, for example, the baby is exclusively fed expressed breastmilk. But, in the case of a WOHM, this might be an option as microwaved breastmilk is still more sound nutrition than formula. That being said, microwaved ebm MUST be treated in the same manor as formula (meaning don't refeed milk left in bottle, don't leave out of the fridge, ect) for food safety reasons. Also, there should be extra care to assure all bottles, pump parts that touch the milk, rings, nipples, and (of course!) hands, are throughly cleaned before handling the milk.
If you think about it, this really does make sense because of the way microwave cooking works! Other types of cooking are much more gentle to the molecules in the food.
