What happens when you vacuum seal food?
Vacuum seal food retains moisture for a prolonged time, enabling you to enjoy its freshness even after it has been stored.
Ultimately, vacuum sealing slows the spoiling process by decreasing ambient oxygen. It also produces an anaerobic environment, which inhibits the development of aerobic bacteria or fungus and prevents the evaporation of volatile components. Other packaging and food processing techniques, such as sous vide cooking, can be used in conjunction with vacuum sealing.
Furthermore, if you’re thinking of freezing your food, vacuum sealing is a fantastic way to prevent it from dehydration and freezer burn. While vacuum seal food is not exactly cheap, they will pay for themselves very quickly.
How long will vacuum-sealed food last?
Vacuum sealing dehydrated food in a high-quality vacuum seal food bags or vacuum sealer rolls from LAVA will make them last for a considerable amount of time. In fact, If you are dehydrating food yourself, vacuum sealing will give them a shelf life of 1-2 years, depending on the food type and the temperature of your storage area.
On the other hand, vacuum-sealed frozen food has an average shelf life of 2-3 years, but it has a 6-12 months shelf life when kept in other methods.
Meanwhile, most vacuum-sealed meals may be stored in the refrigerator for 1-2 weeks, which is significantly longer than the normal 1-3 days.
For raw foods like cheese, a vacuum sealer keeps them fresher for about 4 to 8 months.
Fruits and berries in the fridge last less than a week, but with a vacuum sealer, you can double their shelf life, keeping them fresh for up to two weeks.
Lastly, for cooked meals, you can keep them tasting good for about two weeks with a vacuum sealer.
Is it reasonable to vacuum seal your food?
Other than prolonging the shelf life of your food, vacuum sealers can also offer the following benefits:
- Effortless food organization: Vacuum sealing allows for more efficient and structured packing. Vacuum-sealed food takes up less space in your refrigerator or freezer and will enable you to see all its contents. In return, it will be easier for you and your kids to find the food you want to eat.
- Lesser food waste: Vacuum Seal food leftovers from dinner straight away. This saves you from having to throw out the food and provides you with another quick meal in the future. Freeze the leftovers, and they will last for months, preventing you from eating the same dinner three nights in a row.
- Safer food: Keeping your ingredients in vacuum-sealed bags also prevents cross-contamination, dehydration, and mould growth. Mould and germs require oxygen to develop; therefore, taking it away from the pouch prevents them from growing. You’ll also notice that food stays fresher longer, with less discolouration, texture, or odour changes.
- Retaining the flavour quality: Since vacuum seal food keeps the moisture in meals, it will help keep the taste and flavour. Therefore, you will not have to worry about eating stale or bland food.
Guidelines to properly vacuum seal your food:
- Avoid touching food with your hands. To handle the meal, use clean forks, tongs, or other utensils.
- You should first vacuum seal food and then store the goods in the refrigerator or freezer. Dry foods such as crackers and almonds can be kept at room temperature.
- Low-acid vacuum-packaged meals should be frozen and consumed shortly after heating. Never cook a low-acid vacuum-packed meal and then leave it at room temperature in the vacuum packaging.
- Keep your utensils, cutting boards, and countertops clean.
- Check the sealed food within 24 hours to ensure that it is still sealed. If the bag becomes unsealed, reseal it in a new, clean vacuum seal bag.
- Make sure that food is not cross-contaminated.
- Perishable food that has been vacuum-packed should not be left out of the refrigerator for more than 2 hours at temperatures above 40 degrees.
Should you start vacuum sealing your food?
A food vacuum packer machine is essentially a device that is roughly the size of two boxes of aluminium foil side by side. Its primary function is to suction the air out of the bag to vacuum seal food you’re attempting to conserve.
Furthermore, it is well worth the investment for individuals who buy and cook things in large quantities, such as meats, vegetables, fruits, bread, and even cheese. As explained earlier, vacuum sealers can help extend the shelf life of many items by up to 4-6 times.
Furthermore, buying a food Cryovac machine will help you save a lot of money, time, and counter space. Most importantly, they will prevent your vacuum sealed food from contributing to food waste.
