The possibility of bacterial growth actually increases as food cools after cooking because the drop in temperature allows bacteria to thrive. But you can keep your food above the safe temperature of 140ËF by using a heat source like a chafing dish, warming tray, or slow cooker.
A pure culture of bacteria is suspended in a liquid and quick-frozen (often with liquid nitrogen) at temperatures between -50Â°C and -95Â°C. Sensitive microorganisms require the presence of glycerol (end concentration 15-20 %), which acts as an antifreeze, or extra protein (skimmed milk powder) to protect them.
