what is the promble for heat, cold microorganisms
Microorganisms have different heat resistance levels due to variations in their genetic makeup. Some microorganisms have developed heat-resistant structures or proteins that protect them from high temperatures. Additionally, certain microorganisms may produce spores or biofilms that provide protection during exposure to heat.
starch grains first soften, then absorbs water and swells in the presence of moist heat
Moist-heat cooking is cooking the food in a moist environment. Ways to do this is by boiling, steaming, and braising. This helps to tenderize the food more than through dry heat cooking.
Moist = clouds = heat retention Desert = no clouds = heat loss = cooler
WELL! moist heat is used by heating with steam and the steam can not be formed below 100oC so it is not possible to kill microorganism by moist heat below hundred degree
Moist heat cooking methods for chicken noodle soup include simmering and boiling. Those are really the only moist heat cooking method to use for such a dish.
to heat and moist the air.
Moist heat can lead to caramelization of sugars, which changes their color and flavor. It can also cause sugars to dissolve and become sticky or syrupy. In some cases, prolonged exposure to moist heat can cause sugars to ferment.
The suitable condition for microorganisms to grow is has some air,has nutrient,suitable acidity,water and suitable temperature.
Pyrogens that are destroyed by heat.
Dry heat is a type of heat that is transferred without moisture present, such as in an oven or sauna, whereas moist heat involves the presence of water or steam, like in steaming or boiling. Dry heat tends to cook food faster and form a crust, while moist heat is better for retaining moisture in food.
