Refrigeration used to preserve foods dates back to prehistoric times. At the time, people used snow and ice to store hunting products. Slow freezing was risky; it was not until the 20 th century that the commercialization of frozen foods began with the discovery of a rapid freezing method: the deep freezing. In order to reach a negative core temperature for preservation, there are 2 options: freezing or deep freezing.

Freezing is a technique which involves a slow decrease up to 24h in temperature. The water contained in products is transformed into large ice crystals. This technique is used by private individuals who keep their food stored in the freezer. Disadvantages : The edges of the crystals can end up perforating the food cell wall.

Parts of the water and the most volatile aromas can evaporate. Disorganization of structural tissues can lead to enzymatic and non-enzymatic reactions which alter texture and flavours of the food products. Also they tend to dry out. With this process, the water contained in the cells is finely crystallized. The killing of cells and the proliferation of microorganisms are limited. The cells become dormant as result of the low-temperature. Thus the products treated retain their freshness, textures and flavours keeping their essential nutrients and vitamins.

To ensure optimum efficiency, deep-freezing equipment must be adapted according to the frozen food. It is therefore necessary to observe the freezing capacity given on the data sheet of the deep freezing unit deep-freezer , blast chiller for trays or trolleys , deep-freezing tunnel. Hengel offers deep freezing equipment for food industry professionals and other sectors such as medical on request.

Deep freezing, can cause serious food poisoning if the process is not performed correctly, it is therefore necessary to take numerous precautions to avoid this and to preserve the original quality of the products. Remember to check the temperature and maintain your storage equipment. HYGIENE It is better to deep freeze a fresh product rather than a product that has already started to spoil in order to preserve its qualities. Basic hygiene rules still need to be adhered to even though we are working with low temperatures for although there are fewer microorganism or they become dormant some can survive at low temperatures.

It is therefore essential to:. The shelf life of frozen foods varies from 1 to 24 months according to different food products. It is therefore essential to label them so as not to exceed the recommended expiry date. Defrosting allows, by gradual warming, a frozen product to return to its original state.

During the rise in temperature, microorganisms will wake up and multiply. Depending on the products, it is recommended:. Never refreeze or deep freeze again a product that has been defrosted or put into thawing cycle. Skip to main content. Stay : Stay. Press Press review Press files and releases. Commercial support Documentations. Assembly instructions. Electrical diagrams. Spare parts. Exploded view. What is the difference between these two techniques?

Freezing Freezing is a technique which involves a slow decrease up to 24h in temperature. Re-freezing a product which has been defrosted causes proliferation of bacteria. If they are pathogenic, they can cause food poisoning!

A category that appeared to be headed for a deep freeze is beginning to thaw, thanks to creative manufacturers who are introducing products that appeal to consumers looking for healthy, convenient frozen food products. Frozen food cases —once dominated by products such TV dinners, icy treats and inexpensive pot pies—are seeing an influx of creative products with healthier profiles. Those items, experts say, are attracting consumers who had abandoned or never frequently visited the frozen food aisle.

Refrigeration is a necessary expense for most perishable food and beverage products. Fortunately, technology is providing remedies to the cost squeeze. In industrial freezing, mechanical refrigeration using ammonia is the go-to option, although the risk of ammonia leaks that can harm workers and destroy products is a constant concern. The danger can be minimized with a cascade system that draws much less energy and can attain much lower temperatures, giving companies the option to increase throughput in the same footprint. High electricity costs in Europe have helped make cascade systems mainstream. Relatively low energy prices in North America have slowed deployment.

Deep Frozen vs. Fresh Fish

Fruit and vegetables are tasty and healthy — but they are a delicate matter. And for this reason you should not leave to chance the careful temperature control and gentle product handling in the chilling or freezing processing lines of these sensitive foodstuffs. After all: energy efficiency and environmentally friendly refrigerants enjoy absolute top priority with us. It is especially deep-frozen food that makes it easy as pie to eat healthily and with great variety — without great specialist knowledge, sophisticated nutritional plans, or calendars of the season. In addition, frozen foods make it easier for the growing number of us with allergies and food intolerances to adjust our diet to personal needs. Nutrition scientists can heartily recommend frozen foods. Countless studies have for many years proven that properly frozen vegetables are not only equivalent to their fresh counterparts with respect to vitamin content: it has indeed been evidenced that frozen vegetables in any case are superior to those foods that have been stored for days in refrigerators or that have been in transit for long periods. Deep-frozen foods also represent hygienically flawless products for the consumer, since microorganisms such as bacteria need above-zero temperatures to grow and proliferate. As a rule, we rush through the supermarket to get home on time. No wonder that convenience foods such as deep-frozen products are gaining in popularity.
