Külmutamisega

Külmutamisega is the Estonian term for freezing, specifically in the context of preserving food. It is a common and effective method for extending the shelf life of various food products by slowing down the activity of enzymes and microorganisms that cause spoilage.

The process involves rapidly lowering the temperature of the food to below its freezing point, typically to around -18 degrees Celsius (0 degrees Fahrenheit) or colder. This halts the growth of bacteria, yeasts, and molds, and also significantly reduces the rate of chemical reactions that degrade flavor and texture.

Different foods require slightly different approaches to freezing for optimal results. For example, blanching vegetables before freezing helps to preserve their color, texture, and nutritional value. Fruits are often frozen whole or in slices, sometimes with the addition of sugar or syrup to prevent oxidation and maintain quality. Meats, poultry, and fish are best frozen in airtight packaging to prevent freezer burn, which is dehydration caused by exposure to cold air.

When thawing frozen food, it is generally recommended to do so slowly in the refrigerator. This helps to maintain the food's structure and safety, as rapid thawing can lead to the growth of bacteria. Proper freezing and thawing techniques are crucial for ensuring the quality and safety of preserved foods. Külmutamisega is a widely used practice in Estonian households and the food industry alike.
