Advances in freezing technology and distribution systems have led to an increase in the amount of high quality frozen seafood on the market. As demand for frozen fish and shellfish has grown, so has the vocabulary to describe these products. Here’s a sampling of the frozen lexicon.

FAS (Frozen At Sea).

FAS products may be frozen whole for later thawing and reprocessing on a factory ship or at a plant ashore, or they can be landed, filleted and frozen aboard the same vessel. Ground fish like pollock and cod are often filleted and frozen at sea. FAS products offer a quality advantage because they are frozen quickly after harvest.

IQF (Individually Quick-Frozen).

Pieces of finfish or shellfish fast-frozen as single units, then glazed, bagged and boxed. The “quick” in IQF can refer to cryogenic methods that employ liquid nitrogen or carbon dioxide, or to blast freezing. It simply means the product was frozen in a matter of minutes or hours, not days. Products marked IQF that have been frozen in a storage freezer are incorrectly labeled, as they have been frozen too slowly and thus do not qualify as IQF.

Products frequently sold in IQF form include small, dressed whole fish like whiting, herring or smelt; peeled or shell-on shrimp, crab clusters and legs; whole fish like salmon, which are normally blast frozen, glazed and individually bagged; and scallops for retail sale.

Refreshed.

Seafood that has been frozen, often in blocks, then thawed (or “slacked out”) for resale. If handled properly, the quality of this product is high, though it should be labeled “refreshed” or “previously frozen” to avoid confusion or deception. Fillets labeled “fresh” that appear dry may have been previously frozen.

Twice-frozen (also known as double-frozen).

Fish or shellfish that has been frozen at sea, then thawed for reprocessing ashore and frozen a second time after processing. Microwave heating may be used to partially thaw a frozen shrimp or fish block, permitting separation of individual units still in a frozen state. Fish or shrimp blocks are often “tempered” in this manner, heated until their temperature is just below freezing, at which point portions are chipped off, then battered, breaded and immediately refrozen.

Refrozen, or “double-frozen,” products like these should offer only minimal quality loss if handled properly.

Glazed.

IQF products that have been sprayed with cold water or dipped into icy water, which freezes instantly into a protective film that eliminates air pockets and reduces the likelihood of freezer burn or rancidity. Glaze should be uniform and completely cover the product. Cracks in the glaze (not simply hairline fractures) or “holidays” where the glaze is missing entirely may indicate improper glazing and the necessity to re-glaze. Re-glazing is customary and necessary during prolonged storage when the original glaze has diminished.

Beware, however, of excessive glazing and improper weight claims based on glazed weights.

The question of whether a scallop with the roe on tastes better than a scallop with the roe off, is simply a matter of preference. Every palate is different and thus accustomed to certain flavors and tastes. However, for those who appreciate the finer things in life – the delicacies, if you will – a scallop with the roe on is much tastier than one served with the roe off. For starters, when you eat a scallop with the roe on you can be sure that it was brought to shore alive and therefore the product is likely much fresher than one that is served without the roe.

Seafood Terminology You Need to Know

Knowing the lingo can help you ask the right questions and make smart product decisions.

What do you call music played on a fishing boat? Doesn’t matter, as long as it’s catchy. Don’t groan. Catchwords and other terminology in the seafood business is no joke. Knowing the vocabulary and how the words apply to foodservice can make you a better buyer and help you describe menu items.

Everyone knows fish ends up on a plate or is used as an ingredient. Few people know how seafood gets from the boat to the table. In some cases there are misconceptions about the way seafood is caught, processed and packaged. Understanding words and phrases from four categories—fishing terms, product terms, industry terms and health/safety terms—can lead you to ask the right questions or provide the right answers about seafood.

One of the main advantages of this method of preparing frozen food is that the freezing process takes only a few minutes. The exact time depends on the type of IQF freezer and the product. The short freezing prevents formation of large ice crystals in the product’s cells, which destroys the membrane structures at the molecular level.[2] [3] This makes the product keep its shape, colour, smell and taste after defrost, at a far greater extent.

Another significant advantage of IQF technology is its ability to separate units of the products during freezing, which produces higher quality product compared to block freezing. This advantage is also important for food sustainability, as the consumer can defrost and use the exact needed quantity. There is a range of IQF technologies, but the main concept is to transport the product into the freezer with the help of a processing line belt or infeed shaker. Inside the freezer, the product travels through the freezing zone and comes out on the other side. Product transportation inside the freezer is by different technologies. Some freezers use transportation belts similar to a conveyor belt. Others use bed plates that hold the product, and an asymmetrical movement makes the plate advance by itself through the freezer.[4]

Natural Appearance

The full control over the cooking temperature in the IF Cooker is important for keeping the high product quality and yield: no excessive curling, right color and bite, preserved taste and flavors. Followed by an efficient chilling below 5°C in the OctoFrost™ IF Chiller, the cooking process is stopped immediately. While the low infeed product temperature is crucial for a high quality IQF seafood product.

Energy Efficiency

The rain-shower and cross-flow systems which are at the heart of the IF Cooker and Chiller help achieve the quickest Read more heat transfer while the recirculation system optimizes water consumption. The water in the OctoFrost™ IF Cooker is heated by means of direct steam injection, which is absorbed completely into the water for maximum energy efficiency. The adjustable fans’ speed of the IQF freezer, translates in even more significant energy savings.

High Yield

Temperature of the shrimp’s surface remains below 80°C, which results in at least 1% yield gain compared to forced convection steam cooking. Compared to traditional steam cookers, the yield gain can reach 9%. The quick and efficient cooking and chilling together with the unique aerodynamics of the OctoFrost™ freezer, result into less snow formation when compared to other technologies, which means minimum dehydration and higher yield for the processor.

Food Safety

The OctoFrost™ equipment has been designed to exceed all international regulations on food safety and hygiene. CIP (Cleaning-In-Place) systems, open and cleanable designs, Aisi 316 stainless steel piping – just a few food safety features of these machines. The OctoFrost equipment guarantees 100% food safety regarding homogeneous cooking. No ‘undercooked’ meat, no grey spots, even with small-sized peeled shrimp (PUD).

Individual Quick Freeze: IQF Seafood Demand

When it comes to sea food, we all expect fresh and high-quality produce. However, this is not often the case. With demand for fresh sea food increasing every day, businesses are facing increasing difficulty in acquiring sea food at the quality expected by the customers.

A lot of customers look to flash freeze their sea food inventory for long periods of time to keep themselves stocked and ready to meet demands. However, this is not very effective as the quality of the sea food reduces greatly with normal methods of refrigeration.

Individual Quick Freezing (IQF) helps maintain the fresh quality of sea food while minimizing drip loss. With Individual Quick Freezing, the cell destruction that is caused during the process of refrigeration is minimized thereby maintaining the flavor and texture of the product, even after defrosting.

Availability of Fresh Seafood

While the demand for fresh sea food increases, businesses are faced with an increasing and ever-growing problem; a shortage of actual fresh sea food. While businesses that are located near the cost usually have the ability to have access to fresh sea food, this is not the case for businesses that are located inland.

So how are seafood businesses that do not have the luxury of being located close to the sea side supposed to manage the demands of their consumers and match their standards?

The answer is IQF. With individual quick freezing it is possible to maintain high quality while also flash freezing the seafood individually. This prevents, clumping, discoloration and drip loss.

How you can implement IQF

When businesses try to make a shift towards IQF, there is often a concern. It involves dealing with a newer and unfamiliar technology. But that shouldn’t be a cause for worry. Technology always helps improves our lives, and embracing newer more advanced methods of food production and preservation will definitely help improve the productivity and efficiency of your business.

Given that this is often uncharted territory, let us help you understand how you can implement IQF to freeze your seafood inventory.
