I am aware Most ( ALL ? ) are not made by GOD for exposing to environment above the ambient temps -- + 55 DEG MAX !!
and heating DAMAGES the food value & each repeated heating would cause big damage
As in India we being in Tropical areas -High Temp & High Humidity supports Microb development causing attack on all foods hence what ever we eat we heat ,heat & heat to keep it safe ..Typically Indian Housewife would be Boiling Milk 3 to 4 times as same is progressively consumed ,and in between it is refrigerated..What a loss of Food value ! & Waste of energy !
I plan to widely circulate this info so that only correct process is followed that 1) preserves food value 2) avoids energy wastage ...but such communication must have good data on LAB observations covering Protein Damage --is such data available ?
