Frozen foods are a reasonable way to get your daily amount of fruits and vegetables packed in custom frozen food boxes. People who incorporate frozen foods into their routine may have better diet quality. With so many options in the frozen foods gallery, there are plenty of opportunities to find something you like.
Today, the process of freezing food to preserve it in the finest possible conditions is one of the most extended processes, together with food refrigeration, although it is essential to know the key factors that determine acceptable food freezing temperature maintained with the help of custom frozen food packaging.
What Is Freezing Food?
Food freezing is a food preservation strategy based on exposing food to temperatures below freezing point, a point at which the state of matter changes and the properties of the product are modified, turning it into ice and hardening all the water or moisture contained in the food items. Normally this point is between -18ºC and -35ºC, although this will rely on the type of product to be frozen.
The objective of this process is to eliminate all activity of micro-organisms in the food cover with custom freezer food boxes wholesale without significantly altering its nutritional content, and thus its spoilage. In addition, freezing greatly reduces chemical and enzymatic activity, such as oxidation of the food objects.
What Type Of Freezing Is There?
Depending on the tools used and the speed of the procedure, three types of freezing can be determined:
- Slow: This is the most familiar case and is used for household use or large freezing chambers.
- Medium: It is taken out with cold air tunnels at temperatures down to -40ºC.
- Fast: Mainly used in the industrial and experienced field, it consists of short temperature changes achieving thermal stabilization around -18ºC.
Depending on the freezing technique used, you can differentiate:
- By contact: Custom boxes in the USA are mainly used for seafood and fish, the process is achieved by extracting heat from the food thanks to the contact of thermally conductive plates at very low temperatures.
- Cryogenic: This procedure is carried out with cryogenic liquids such as nitrogen, carbon dioxide, freon, etc. This method is also part of deep freezing due to its speed, although it is very expensive.
- By air: This procedure is carried out employing cold air currents that extract the heat from the food until a managed temperature is reached.
Recommendation For Freezing Food
Furthermore, it is essential to know that, for an optimal freezing process, freezers should ideally always be kept below -18ºC. On the other hand, it is also essential not to freeze any hot food, as this would cause the moderate temperature of the freezer to rise and therefore negatively impact the rest of the stored products in custom tuck top boxes. Protection of the food to be frozen is also a crucial factor. Freezing in airtight containers, or airtight bags, or freezing the food under a vacuum can significantly help preservation.
Food That Should Not Be Frozen
It is recommended not to subject these foods to freezing methods because they may lose properties, mainly because of their texture. Although freezing is possible if carried out correctly, their capacity to deteriorate in this process is more significant. These include:
- Vegetables and fruits that will later be ingested raw. Although it is possible to freeze them if they have been processed before consumption.
- Custom printed kraft boxes for foods with high-fat content, such as creams and some sauces, tend to break when frozen.
- Dairy products in known are at risk of shattering.
- High-starch foodstuffs such as pasta, potatoes, and rice.
Benefits Of Frozen Foods
Fruits and vegetables are selected at peak ripeness and often frozen within hours, closing in nutrients and flavor. Normally, frozen foods retain their vitamins and minerals and there is no modification to the carbohydrate, protein, or fat content. In some cases, frozen foods contain more vitamins and minerals compared to fresh because fresh foods lose vitamins and minerals over time while freezing holds nutrients. Frozen foods can be a suitable and affordable method to incorporate healthful foods from every food group, including whole grains, fruits, vegetables, protein, and dairy.
To keep frozen foods safe, follow the cooking methods specified on the custom frozen food boxes. The freezing procedure does not entail a notable loss of vitamins or proteins from the food. However, it is necessary to protect the food with special wrappings that protect the texture of the food from freezer burn.
