The plate looks promising as it goes in the microwave, only to come out altered. Edges become hard, textures are altered, and moisture appears to evaporate completely. It has been assumed that the problem arises from the food being cooked; however, the real cause of this effect lies in how heat is transferred.
A study conducted and published in Food Research International reveals that high-temperature re-heating makes moisture disappear faster from the surface of the food. Heat does not get transferred evenly in some cases, leading to some areas becoming dry even as the rest remains cold. Such an inconsistency in the transfer of heat makes food difficult to consume.
You can preserve its structure by controlling the heat
The modification of methods of heat delivery may be extremely effective in improving the result. Research proves that low-powered microwaving leads to a more gentle energy distribution, which results in reduced moisture evaporation without causing any structural damage. The steaming technique can be another effective method for restoring the quality of food since it provides a simultaneous heating and moisture supply to the product.
IMG Research on reheating starch-containing products demonstrates that a more moderate regulation of air and moisture flow prevents moisture loss and preserves the texture. Thus, one can conclude that the process of reheating is not only associated with the attainment of a certain temperature but with the heat-moisture balance as well.
Safety without compromise?
Heating must guarantee that there is no health hazard posed by the food, since failure to reach proper internal temperature may result in survival of disease-causing microorganisms. The importance of reaching the proper internal temperature becomes more evident in cases of foods such as rice and protein-based meals. Nonetheless, it is worth noting that one does not need to use strong heat to get to safety levels.
Heat evenness can accomplish that goal and still ensure that quality is maintained.
