The application of low temperatures in food is one of the most widespread and oldest conservation systems in the world.
There are three types of food preservation by cold depending on the storage temperature: refrigeration, freezing and deep-freezing. In this article, we will focus on conservation by refrigeration, allowing performed by domestic refrigerators or coolers if you need to keep food away from home.
What is refrigeration?
Cooling is a method of preserving food which preserves for a certain time (days or weeks) by applying temperatures between 0 and 5 degrees Celsius.
Why the cooling efficiency in the food preservation is?
Basically the activity of microorganisms and enzymes of the food itself are slow on low tempetratura, with the consequent delay in the degradation of food components.
Consequently, food last longer and at the same time pathogens will be inhibited in their growth, so it will allow maintaining the security of food. Importantly, no cooling prevents degradation of food but this phenomenon is delayed.
How long can be kept refrigerated foods?
Depending on the type of food, retention days at temperatures between 0 and 5 degrees vary. Generally we can distinguish between the following types of food:
- Fresh fish: 2 days.
- Raw meat: 3 days.
- Meat and fish cooked 3 days.
- Open Milk: 4 days.
- Desserts: 4 days.
- Cooked vegetables: 4 days.
- Raw vegetables: 5 days.
- Eggs: 2-3 weeks.
What happens to pathogens?
Pathogens are microorganisms that are unable to multiply quickly in food below 5 ° C, so the food storage below these temperatures will ensure its preservation for several days according to the table above.
However, with the passage of days, microorganisms of alteration they will deteriorate the food making the signs of the disturbance will be therefore safety signs as when food is altered will not be consumed and they avoid high levels of pathogens.
What to do in case you need to keep food away from home for a few hours or days?
The most important thing is not to break the cold chain, ie, prevent food are at temperatures below 5 degrees, so that the use of coolers high quality as the Igloo coolers ensure the conservation of the ice during the time necessary for the consumption of food is safe. Refrigerators used to camping, to go to the beach, for sports or go hiking and always keep your food chilled.
Away from home, always use igloo coolers!
