How Seafood Factory Freezes Freshness at -18°C

Oct 27, 2025

Imagine pulling a salmon fillet from your freezer and having it taste as if it were just caught hours ago. At Seafood Factory, this isn’t wishful thinking – it’s our everyday promise. We freeze our seafood at -18°C (0°F) to lock in peak freshness, flavor, and nutrients. In this article, we’ll reveal why freezing at -18°C is the magic number for preserving seafood, how our advanced flash-freezing techniques work, and what it means for you in terms of quality, safety, and convenience.

Why -18°C is the Magic Number for Freshness

Freezing = Nature’s Pause Button: Freezing seafood to -18°C or below effectively hits pause on spoilage. Harmful bacteria can’t grow at this temperature, and even parasites are destroyed. That’s why -18°C is the gold standard for long-term food storage – it keeps your seafood safe to eat indefinitely. In fact, food safety authorities recommend 0°F (-18°C) as the ideal freezer setting to maintain quality and safety.

Locks in Flavor and Nutrition: By rapidly bringing seafood down to -18°C, we preserve its just-caught quality. The cold halts enzymatic activity that would otherwise degrade texture, taste, and color. Vitamins, proteins, and omega-3s remain intact. Frozen seafood, when handled properly, is just as nutritious as fresh, so you get all the health benefits of fish without compromise.

Extended Shelf Life: At refrigerator temperature, fresh fish might last only a couple of days. But at -18°C, that same fish can maintain top quality for months. Whether it’s hearty wild-caught fish or delicate shellfish, freezing immediately after harvest means you can enjoy ocean-fresh flavor well beyond the catch date. Our customers love the flexibility of having premium seafood on hand whenever inspiration strikes – no rush, no waste.

Flash Freezing at Peak Freshness

To truly freeze “freshness” in time, speed is key. Seafood Factory uses flash-freezing technology to rapidly chill seafood to -18°C right when it’s at its prime. This quick freeze prevents the formation of large ice crystals inside the fish:

  • Faster Freezing, Better Texture: When fish is frozen slowly, water inside forms big ice crystals that can damage cells, leading to mushy texture. Our flash-freeze process (often in industrial blast freezers well below -18°C) takes mere minutes, so only tiny ice crystals form. The result? Once thawed, your seafood has the same firm, flaky texture as it had fresh.
  • Flavor Sealed In: Rapid freezing locks in natural juices and brininess. A raw salmon portion or shrimps flash-frozen at peak freshness will cook up tender, moist, and full of flavor. There’s no time for flavor compounds to break down – everything is preserved just as nature intended.
  • IQF – Individually Quick Frozen: We freeze each piece of seafood individually (a method known as IQF). Fillets, shrimp, and scallops don’t clump together in a solid block. This means you can easily grab exactly the number of pieces you need without having to thaw the whole batch. From single-serving fish fillets to bulk bags of calamari, every item remains separate and easy to handle.

Thanks to flash freezing, our seafood arrives to you in pristine condition. There’s no “freeze burn” or off flavors – just ocean-fresh taste ready to be unleashed in your kitchen.

Quality and Safety Benefits You Can Trust

  • Peak Freshness, Anytime: Because we freeze our catch at its freshest, you get to enjoy seasonal delicacies year-round. Craving wild snapper or succulent shrimp out of season? With Seafood Factory’s frozen selection, you can have it any month of the year. The fish you thaw today will taste as vibrant as the day it was caught.
  • Consistent Premium Quality: Every portion is frozen at the same high standard, which means no surprises. Unlike “fresh” fish that can vary day by day, our frozen seafood delivers reliable excellence each time. For example, our smoked fish and ready-to-cook meals are preserved at peak quality, so your favorite recipes come out perfect each try.
  • Food Safety and Peace of Mind: Freezing at -18°C not only keeps bacteria at bay, it also makes seafood safer for raw or lightly cooked dishes. Love sushi, poké or ceviche? Our frozen fish is sashimi-grade because the deep freeze eliminates parasites. You can indulge confidently, knowing your seafood passed through a kill-step for pathogens. Plus, with vacuum-sealed packaging (more on that next), there’s no risk of contamination during storage.
  • Less Waste & More Value: Buying frozen helps you reduce waste and save money. Use only what you need and keep the rest frozen for next time. No more tossing out fish that spoiled after two days in the fridge. Stock up on family packs or bulk deals and enjoy them at your own pace. Our portion-controlled packs make meal planning easy – whether cooking for one or a whole family, you decide how much to defrost.

Our Process: From Ocean to Freezer to Your Door

At Seafood Factory, we take numerous steps to ensure that frozen doesn’t mean “lower quality” – it means better control over quality:

  • Flash-Frozen at Sea or Soon After Catch: We work closely with our suppliers to flash-freeze seafood at peak freshness. Many of our wild-caught fish are frozen on the boat or immediately upon landing on shore. This immediate icing and freezing “pause time,” effectively preserving just-caught freshness until you’re ready to enjoy it.
  • Vacuum-Sealed Packaging: All Seafood Factory products come in airtight, vacuum-sealed packs. This locks out air and moisture, preventing freezer burn and oxidation. The color, texture, and taste are guarded inside that package. When you open a pack of our frozen sea fruits (like mussels or calamari), you’ll smell the ocean brine, not “freezer smell,” thanks to this extra level of protection.
  • Strict Cold Chain Delivery: We maintain -18°C throughout the journey from our facility to your home. Our storage freezers, refrigerated trucks, and insulated delivery boxes ensure your order stays deeply frozen solid until it arrives. You’ll receive your seafood as cold as if you just pulled it from your own freezer. This unbroken cold chain means no thaw-refreeze cycles, which can degrade quality. It’s a straight line of frostiness from us to you!
  • Quality Checks and Standards: Our factory (Seacook) is equipped with state-of-the-art technology and adheres to international food safety standards (HACCP, ISO 22000). Every batch of seafood is inspected for quality before and after freezing. We take pride in being Egypt’s premium seafood supplier, so if it’s not top-notch, it doesn’t leave our facility. When you see the Seafood Factory label, you know you’re getting seafood that meets rigorous standards for freshness and safety.
