Can You Vacuum Seal Meal Prep Containers? The Ultimate Guide

Hey there! As a home improvement expert who also loves meal prepping healthy foods, I‘m excited to share everything I‘ve learned about vacuum sealing meal prep containers. This thorough guide will equip you with the knowledge to keep your homemade meals fresh and delicious for way longer.

Why Vacuum Sealing is a Game-Changer for Meal Prep

Vacuum sealing is hands down the best way to preserve your meal prepped foods. Let me explain the science behind why it works so well:

It Slows Bacteria Growth

Bacteria needs air to grow. By removing the air from your containers, vacuum sealing creates an anaerobic environment that puts bacteria into hibernation mode, stopping it from multiplying. This keeps your food safer for longer.

It Prevents Freezer Burn

You know that awful dry, leathery texture freezer burn causes? By eliminating air exposure, vacuum sealing protects your foods from this quality-destroying ice crystal formation during freezing.

It Reduces Oxidation

Oxidation is the chemical reaction that causes fading, rancidity, and nutrient loss. Vacuum sealing lowers oxidation by removing the oxygen which fuels this deterioration process.

It Stops Moisture Loss

Air absorbs liquid from your food, leading to dryness and textural changes. Vacuum sealing locks in moisture content so foods stay juicier.

According to food preservation experts, vacuum sealing can extend refrigerated shelf life by 2-3x and freezer life by 3-6x compared to conventional storage methods.

That means the meals you prep on Sunday could still taste great by the end of the following week! Let‘s look at how to vacuum seal for maximum freshness.

Foods I Recommend Vacuum Sealing

While most foods can be vacuum sealed, some hold up better than others based on my experience:

Great Choices

• Raw and cooked meats
• Poultry
• Fish fillets
• Soups, stews, and chili
• Sauces, dips, and salsa
• Cooked rice and pasta
• Hard cheeses
• Baked goods like muffins and cookies

Moderate Choices

• Berries like strawberries, blueberries and raspberries
• Soft fruits like peaches, plums and apricots
• Lettuce and other delicate greens

*For these, seal gently on low pressure to avoid crushing.

Avoid Sealing

• Broccoli, cauliflower, cabbage, brussels sprouts
• Leafy greens like kale, chard, herbs
• Fresh potatoes and root veggies
• Soft berries like blackberries

*These break down more quickly, even when sealed.

I recommend chilling all cooked foods to 40°F or below before sealing. Raw meats should already be fully chilled.

Avoid sealing anything with high liquid content, like soups, before they‘re thoroughly cooled – this can ruin the seal.

Now let‘s talk about the best containers for meal prep vacuum sealing.

Meal Prep Containers I Recommend for Vacuum Sealing

The right containers make all the difference. Look for these features when shopping for meal prep containers to vacuum seal:

Rigid Plastic Construction

Flexible plastics can warp or cave in when vacuum sealed. Rigid plastic tubs made of PET, polypropylene, or Tritan maintain their shape.

BPA-Free Materials

BPA (Bisphenol A) can leach into foods, especially acidic and fatty items. Choose BPA-free containers – I prefer glass or titanium-reinforced plastic.

Lids with One-Way Valve/Vent

The lid needs a one-way valve so air can evacuate from the container interior when vacuum sealing.

Secure Sealing Edges

Smooth, flat rims create an airtight barricade when sealed. Avoid cheap containers with warped, uneven edges.

Stackable and Clippable

Square shaped containers with lids that snap together or interlock make efficient use of freezer space.

Microwave and Freezer Safe

Ensure containers and lids are microwave reheatable and able to withstand freezing temperatures without cracking.

Reusable and Durable

Look for commercial-grade, thick plastic that can withstand repeated uses and washings without warping, cracking, or leaking.

I personally love Oxo Good Grips Smart Seal Containers. The BPA-free plastic is thick and sturdy, the one-way valve lid design seals perfectly every time, and the rectangular shape with interlocking lids helps me tetris-stack them in my freezer. They‘re worth the investment for long-term use.

Step-By-Step Guide to Vacuum Sealing Your Containers

Vacuum sealing meal prep containers only takes a few minutes once you get the hang of it. Follow these simple steps:

1. Prep Food for Sealing

• Cook, cool, and portion your meals out into the containers. Chill fully.

• Leave 1 inch of headspace between the food and the lid. This gives the vacuum pressure room to work.

• Make sure container rims are clean before sealing to prevent messes.

2. Secure Lids

• Place lids on containers, snapping or locking the edges into place if possible. Lids should fit snugly.

• Check that the one-way valve on the lid is clear of food debris before sealing.

3. Vacuum Seal

• Put the filled container in your vacuum sealer machine. Follow the product instructions.

• Run the vacuum cycle. This removes air through the one-way valve to seal the container. Takes just 1-3 minutes.

• You‘ll know it‘s properly sealed when the lid adheres tightly to the base with no air pockets.

4. Label and Freeze

• Label each container with contents and freeze-by date before freezing.

• Arrange stacked containers efficiently in your freezer. Use oldest first based on dates.

For fridge storage, keep containers on the bottom shelf below 40°F. Avoid opening the fridge more than necessary to limit temperature fluctuations.

And that‘s all there is to it! Now let‘s go over thawing and reheating your vacuum-packed meals.

Thawing and Reheating Vacuum Sealed Foods

To safely thaw and reheat your frozen vacuum-sealed meals:

• Thaw in the fridge overnight before reheating. Never thaw foods at room temperature.

• Open container and remove lid fully before reheating. Do not microwave sealed containers.

• Microwave thawed food on medium heat until hot, at least 165°F. You can also use the stove.

• Reheat frozen soups/stews still sealed in boilable bags, but carefully open hot bags to avoid steam.

• Avoid air exposure after opening by eating thawed foods within 3-5 days. Don‘t refreeze thawed items.

Pro tip: Pop containers in the fridge the night before to thaw, then just microwave and eat when you‘re ready!

How Long Does Vacuum Sealed Meal Prep Last?

Wondering how long your meal prep will stay fresh when vacuum sealed? Here are the general guidelines I go by:

Fridge Storage

Most foods will remain good quality for 2-3 weeks sealed in the fridge. Just be sure to store containers on the bottom shelf at 40°F or below.

Freezer Storage

In the freezer at 0°F, vacuum sealed foods can last:

• Raw meat, poultry, fish: 6-12 months
• Soups, stews, sauces: 6-12 months
• Cooked rice, pasta: 1-2 years
• Baked goods: 1-2 years
• Hard cheeses: 2-3 years

Always label containers with contents and freeze-by date, and use oldest meals first when reheating.

I like to freeze two weeks worth of meals at a time, pulling out the next week‘s containers to thaw in the fridge as I‘m finishing up the previous week. This rotation system helps reduce waste!

Troubleshooting Vacuum Sealed Meal Containers

Even with proper sealing methods, problems can pop up. Here‘s how I troubleshoot common vacuum seal issues:

Warped or Leaking Lids

Cheap plastic can become misshapen over time, resulting in a broken seal. Look for thicker, better quality containers. Glass and titanium-lined plastic tend to hold their structure with repeated uses.

Food Spoilage

If you notice off-colors, odors, or slime inside a sealed container, toss it. Vacuum sealing slows but doesn‘t prevent spoilage fully. Stick to recommended fridge/freezer times.

Freezer Burn

If you notice ice crystals or dehydration in frozen items, there may have been too much air left inside before sealing. Try leaving less headspace when filling containers.

Crushed Food

Some vacuum sealers have high pressure settings. Use lower settings for delicate items like berries to avoid crushing. Leave a bit more headspace as well.

Difficulty Sealing Lids

Make sure to fully snap lids into place before vacuum sealing. Clean any food debris off rims. Double check the valve is unobstructed so air can release.
