An Extensive Guide to Commercial Vacuum Sealing Fish

Oct 25, 2023

The art of preserving fish has been a part of human history for centuries, from salting to smoking and canning. However, as technology advances, we find more efficient and safer ways to extend the shelf life of our catch. One such method that has gained popularity over the years is vacuum sealing. But, what is vacuum sealing? This comprehensive guide will discuss everything you need to know about commercial vacuum sealing fish.


Understanding Vacuum Sealing


Vacuum sealing is a method of packaging that removes air from the package prior to sealing. This technique involves placing items in a plastic film package, removing air from inside, and sealing the package. The intent is to extend the shelf

life of foods by creating an airless environment to inhibit the growth of bacteria, fungi, and other spoilage organisms.


Why Vacuum Seal Fish?

There are several reasons why vacuum sealing is an excellent method for preserving fish:


  • Extends Shelf Life: Vacuum sealing can extend the shelf life of fish by up to two years if done correctly. The absence of air slows down the oxidation process, which leads to spoilage.
  • Preserves Quality: Vacuum sealing not only keeps fish fresh but also maintains its texture and flavor.
  • Prevents Freezer Burn: Freezer burn occurs when air comes into contact with the surface of frozen food, resulting in discoloration and a change in texture and flavor. Vacuum sealing removes air, hence preventing freezer burn.
  • Saves Money: By extending the shelf life of fish, vacuum sealing reduces waste resulting from spoiled fish. This can translate into significant savings for commercial fisheries.


Commercial Vacuum Sealing Fish: The Process

Now that we have a basic understanding of vacuum sealing and its benefits, let's delve into the process of vacuum sealing fish in a commercial setting.


Preparing the Fish

The first step in vacuum sealing fish is the preparation. This includes cleaning the fish and cutting it into the desired portions. Depending on how you plan to serve the fish, you can either freeze the whole fish or cut it into portions.


Pre-Freezing

Most fish contain high levels of moisture, which can make vacuum sealing challenging. It's therefore recommended to pre-freeze the fish before sealing. Place the prepared fish on a baking tray, wrap it with plastic wrap, and pop it in the freezer for about one to two hours.


Vacuum Sealing

After pre-freezing, the fish is ready to be vacuum sealed. Weigh out serving size portions and place the individual portions in vacuum sealing bags. Ensure the area where the seal will be is completely dry to prevent failure of the seal.


Labeling

Once the fish is sealed, it's crucial to label each package. The label should include the type of fish, the date it was frozen, and any other relevant information.


Storing

Finally, the vacuum-sealed fish should be stored in the freezer until it's ready to be used. Properly vacuum-sealed fish can last in the freezer for up to two years.


Thawing Vacuum Sealed Fish

Thawing vacuum-sealed fish correctly is critical to maintain its quality. The best method is to thaw the fish slowly in the refrigerator. This allows the fish to reabsorb some of the excess moisture, resulting in a better texture and flavor once cooked. Quick thawing methods can cause the fish to lose moisture, leading to a drier, tougher texture.


Enhancing the Vacuum Sealing Process with Technology

Henkelman's commercial grade vacuum sealers are a game-changer for fish processors. These vacuum sealers come equipped with advanced features such as soft air, liquid control, and gas flush technology. Soft air ensures a smooth and gradual return of air into the chamber, preventing damage to the product and the packaging. Liquid control is perfect for vacuum sealing wet products like fish, as it prevents moisture from reaching the seal bar. Gas flush technology replaces the oxygen in the bag with an inert gas like nitrogen, further extending the shelf life of the fish.


Conclusion

Vacuum sealing is a valuable tool for commercial fisheries. It extends the shelf life of fish, preserves its quality, prevents freezer burn, and saves money by reducing waste. However, to get the most out of vacuum sealing, it's crucial to follow the correct process, from pre-freezing to storing. Further, investing in advanced vacuum sealing technology, like Henkelman's vacuum sealers, can enhance the process and offer additional benefits. So whether you're a commercial fishery looking to extend the shelf life of your catch, or a restaurant seeking to offer the freshest fish to your customers, vacuum sealing could be the solution you've been looking for.

Not all plastic is bad??!! Why do vacuum bags play an important role in reducing food waste. According to data from the United States Department of Agriculture (USDA), an unsettling 40% of food produced annually ends up in the trash. This equates to approximately 36 million tons of food, with a staggering monetary value of $162 billion per year. The majority of this waste is due to spoilage, often within the retail and household sectors. Further, the implications of food waste extend beyond mere economic repercussions. Spoiled food releases methane, a greenhouse gas more potent than carbon monoxide. The resources wasted in the process - water for cultivation, fuel for transportation - exacerbate the environmental impact. Therefore, it is in everyone's best interest to pinpoint effective strategies to minimize food waste. One such strategy lies in the choice of packaging. Packaging: The Silent Hero in Food Preservation Contrary to popular belief, food packaging plays a significant role in combating food waste. Plastic packaging, for instance, contributes substantially to the reduction of food spoilage by providing a physical shield against environmental factors that speed up spoilage. This barrier prolongs the shelf life of food products. Innovations in packaging, such as oxygen-scavenging additives, can further increase shelf life by actively removing oxygen from the packaged environment. This is particularly important given that food now travels much further before consumption. The right packaging not only protects the food during transport but also provides instructions for correct storage and handling, thereby preserving its contents once in the consumer's hands. Intelligent Packaging: A Key to Reducing Food Waste Intelligent packaging design has the potential to reduce spoilage by anticipating common packaging failures. The best packaging companies can predict the causes of these failures and implement design modifications to safeguard the contents. With the right engineering, it's possible to analyze package damage trends and devise solutions to address these specific issues. The Paradox of Packaging While we often associate packaging with environmental pollution, the paradox is that efficient and responsible use of packaging technology could significantly reduce our food waste. For instance, vacuum packaging that prevents oxidation can ensure that meat stays fresh on shelves for eight to fourteen days, compared to the usual two to four. Not only does this cut down on waste, but it also appeals to consumers. According to Mintel's 'Transparent Food Packaging' report, roughly 40% of US shoppers would opt for a product among competitors if they could clearly see its contents. The Vacuum Packaging Solution Vacuum packaging technology, such as that used by Sainsbury's supermarket has shown noticeable benefits. This packaging extends the shelf life of dairy and meat products, which can now be kept in refrigerators for a longer time, thus reducing waste. While vacuum packaging does contribute to carbon emissions, it importantly reduces the waste of the food product produced. For each ton of waste, the equivalent of 3.5 tons of carbon dioxide are released without any product having been put to good use. Conversely, a ton of packaging results in emissions of 1-2 tons. The Challenges of Vacuum Packaging Like any solution, vacuum packaging is not without its drawbacks. One of the key issues is that it is not as easily recycled as other types of packaging. However, considering the rapidly growing global population, estimated to approach 10 billion by approximately 2050, it's urgent that we find ways to feed these numbers. Reducing the amount of food, we waste is a critical part of this, and vacuum packaging is a step in the right direction. The Future of Food Packaging With the ongoing advancements in packaging technology, it's reasonable to believe that we can overcome the current challenges of vacuum packaging, making it a sustainable solution for the future. The aim is to strike a balance between the environmental impact of packaging and its effectiveness in reducing food waste. Conclusion: Fresh Foods Fresh, Reduce Waste and Over Production of Food In conclusion, vacuum bags play an essential role in keeping our foods fresh, reducing waste, and consequently curbing overproduction of food. By keeping food shelf-stable for two to four times longer in the fridge and for months in the freezer, vacuum bags significantly cut down on food waste. This, in turn, leads to reduced food purchasing and lower overall food production. While there are challenges to overcome, particularly in terms of recycling, the benefits of vacuum packaging technology are making a significant difference in our fight against food waste.
