People in ancient times use ice and snow to preserve their food and keep it cold to last long. This phenomenon has gradually built and extravagantly improved with the inventions of technology. Over time, it becomes a need of every house, industry, and commercial units with small to large scale manufacturing. Therefore, it is now considered a must-do task in the food processing, handling, and transportation industry.
Let’s have a look at why freezing is so important
Food items and products require proper temperature and environmental conditions to preserve and stay safe for a long time. Preserving food items requires some technology and operations to perform it better and let you store food products of your choice.
The freezing process will delay the spoilage of food products and keep your food products safe by preventing the rapid growth of microorganisms and by slowing down the enzyme activity that causes food to spoil. With freezing technologies and procedures, the water in the food freezes and becomes ice crystals, making it unavailable to those microorganisms that need it for their growth. However, most of these microorganisms, except parasites, remain alive within food products while its freezing process, that’s why food products must be handled safely both before freezing and once defrosted.
Rapidly freezing the food products improves the quality of the food. The faster the food freezes, the smaller the crystals of ice forms. These small crystals are meant to do less damage to cell walls of food products. On the contrary, the slow freezing process is meant to produce large ice crystals which then punch the cell membranes of food products.
As a consequence, when foods with large ice crystals are defrosted, there is more dripping and loss of liquid from those products. Small crystals are unstable and over time grow to form larger crystals. This is more challenging and more significant in the freeze-thaw cycle in frost-free freezers. Whereas, in the defrosting period, the food thaws comparatively low or in beginning, allowing ice crystals to grow and becoming more dangerous for cells when they refreeze.
Another thing that disturbs the freezing cycle is the opening of the freezer door, allowing the heat to enter the freezer and repetition of this freezing thaw cycle. Therefore, choosing the right type of freezer according to your requirements and food products enables this process to carry out smoothly and result in fewer problems and requires economical solutions.
These all make freezing so important in today’s era. Food products couldn’t go a long way without preserving through the freezing process and their quality, essence, flavour, and colour may vanish if you don’t do so. You just have to choose wisely which option is better for you and matches your requirements.
