How it’s done

How can the Micvac method help reducing food waste?

Micvac is the antidote of food waste in several ways. A portion cooked meal is less likely to be thrown away. And Micvac’s unique keeping qualities with extended shelf life, reduces waste all through the logistic chain; during transportation, storage in warehouse, in the store and finally in the fridge in the home of the consumer.

How do microwaves heat food?

The microwaves set the water molecules in motion very rapidly. The motion creates friction heat which warms up the food.

How is the vacuum created?

As the food passes through the microwave tunnel the food is heated up. At a certain temperature it starts to generate steam. The steam increases the pressure in the package and opens the valve. The air inside the package escapes through the valve. After the process the head space consists of only steam which condensates and thus causes the vacuum.

Can I heat up the food again if I didn't have the time to eat it?

Yes, if the food gets chilled again after heating and kept cold the food can be reheated again. The initial shelf life and quality will be reduced.

How do I know when the food is ready when reheating in the microwave?

When the food is warm enough to eat, the valve will make a whistling sound.

If I don't have the time to eat the food right away, how long does it stay warm in the package?

If you don’t open the package, the meal will stay warm up to 20 minutes.

If my microwave is old, how will that affect the heating of my meal?

Warming your meal will take a little bit longer but you will still hear the whistling sound when the food is warm enough.


How can I know if a Micvac plastic container is okay to use in the microwave oven?

The Micvac container and film/valve are designed for microwave heating. If you want to make sure your other plastic containers, packages and wraps are microwave-safe as well, check the item or its packaging label and follow given instructions.

How can Micvac packaging help to reduce food waste?

An extended shelf life is one of the most important parameters to avoid food waste. The longer it last on the shelves (preferably without preservatives), consumers have more time to purchase and consume the food and there is no need to through anything away.

Is the package really safe to use in the microwave?

Yes, it’s safe! All materials are thoroughly tested and Micvac can provide DoC and/or Normpack certificates for all materials.

Is the packaging recyclable?

The tray is fully recyclable.

How should the package be recycled?

The tray and the film/valve should be sorted as plastic at recycling stations.

Food safety & Quality

Does food cooked with the Micvac method contain acrylamide?

No. The Micvac method does not reach the high temperatures required to produce acrylamide.

Does microwave-cooked food lose nutrients?

Microwaving is a gentle cooking method which ensures the nutrients are preserved at a high level. When you cook food in a microwave, the water in the ingredients boils. It’s a bit like steaming. Because heating is rapid, vitamins are retained better than in traditional cooking.

How can I be sure that a Micvac product is safe?

When the food is pasteurised, the package is sealed airtight – a guarantee that no recontamination can take place. The vacuum is a visible proof of this – as long as it remains unbroken and stored in a specified cold condition, the food is safe.

Is food cooked or heated in a microwave oven carcinogenic?

No. Food cooked or heated in a microwave oven is not carcinogenic. All that happens in a microwave oven is that the water in the food boils, nothing else.

Is the package safe to use for food?

All materials in Micvac packaging are approved in accordance with international food packaging criteria, ensuring that no harmful substances are released during cooking or reheating.

How can the food get as long shelf life without any preservatives?

The food inside the package is cooked and pasteurised, and under vacuum, which ensures a safe product with a long shelf life, without the need for preservatives, as well as a good, preserved quality.

What does it mean that the food is pasteurised?

Pasteurisation is a process in which packaged foods are treated in a temperature high enough to kill bacteria and microorganisms and extend shelf life.
