Less food waste

Zero waste: Keeping food fresh and getting creative with leftovers.

zero-waste_header.jpg
Print

Huge amounts of food end up in the bin every day. Planning your grocery shopping, storing it properly and adopting a more conscious approach to what you eat can all help to reduce food waste. Even small changes can help to cut waste or even avoid it completely. But nobody's perfect: We don't need to achieve a zero waste lifestyle immediately, we all just need to start. Equipped with a few tricks for keeping fruit, vegetables and other precious produce fresh, and even reviving a few things past their best, you can reduce food waste to a minimum or even eliminate it entirely. Why not start getting creative with your leftovers?

Voedselverspilling tegengaan en voedsel langer vers houden

Door voedsel gekoeld te bewaren, in te leggen of in te maken, kun je de houdbaarheid verlengen en zo voorkomen dat het in de prullenbak belandt.

zero-waste_slider-1_best-before-dates_card-1.jpg

‘Ten minste houdbaar tot’-datum

De 'ten minste houdbaar tot'-datum is een richtlijn, in tegenstelling tot de 'te gebruiken tot'-datum

Alleen omdat yoghurt een paar dagen over datum is, wil dat nog niet zeggen dat de yoghurt niet meer lekker is en dat je 'm niet meer kunt eten. Tot deze datum garandeert de producent simpelweg dat het product, indien correct bewaard, smaak, geur en voedingswaarde behoudt. Gekoelde gemaksproducten, zoals verse pasta of worst moet je niet lang na de houdbaarheidsdatum eten. Ze kunnen bacteriën bevatten die je niet kunt zien, ruiken of proeven, maar waar je wel ziek van kunt worden. Bij twijfel kun je ze het beste weggooien. Dat geldt ook voor bederfelijke etenswaren, waar meestal een 'te gebruiken tot'-datum op vermeld staat. Na deze datum moet je bederfelijke producten weggooien.

Bewaren en koelen

Het fifo-principe en temperatuurzones in je koelkast

Zet verse etenswaren achteraan neer en schuif oudere etenswaren naar voren. Aan de hand van het 'fifo'-principe (first in, first out) kun je makkelijk bijhouden wat vers is en wat niet. Het is bovendien goed om te weten dat een koelkast verschillende temperatuurzones heeft. Boven de groentelade geldt, hoe hoger het plateau, hoe hoger de temperatuur. Bij het laagste plateau, vlak boven de groentelade, is de temperatuur het laagst. De koelkastdeur wordt het meest opgewarmd als de koelkast geopend wordt. Om ervoor te zorgen dat voedsel in de koelkast zo lang mogelijk vers blijft, moet je het dan ook op de juiste plek bewaren. Meer tips vind je onder ‘De beste manier om voedsel te bewaren’.

Invriezen

Waar je op moet letten als je voedsel in je vriezer bewaart

Micro-organismen gedijen niet zo goed bij lage temperaturen. De beste manier om voedsel vers te houden is dan ook invriezen. Ga als volgt te werk om etenswaren efficiënt in te vriezen:
- Vervoer bevroren producten in koeltassen of geïsoleerde koelboxen om te voorkomen dat de koelketen doorbroken wordt.
- Laat bevroren producten in de koelkast ontdooien en zorg dat je het vocht dat daarbij vrijkomt opvangt, zodat alles hygiënisch schoon blijft.
- Vries eten in porties in, zodat je altijd de juiste hoeveelheid kunt ontdooien.
- Bewaar etenswaren altijd in diepvrieszakken in de vriezer om te voorkomen dat ze uitdrogen of hun smaak verliezen.
- Noteer de datum op de diepvrieszakken. Niet alle voedsel blijft even lang vers in de vriezer.

Geconserveerd voedsel

Inmaken, inleggen en fermenteren

Ja, het is misschien iets wat je oma vroeger deed, maar inmaken, inleggen en fermenteren is weer helemaal in! Op die manier kun je voedsel op een koele, droge en donkere plek tot wel een jaar bewaren. Vermeld altijd de inmaakdatum op de potten en zet ze achteraan in je keukenkastje of voorraadkast neer, zodat je oudere producten als eerste gebruikt. Als het deksel niet goed vastzit, het vocht troebel of verkleurd is of als de geconserveerde etenswaren niet goed ruiken, kun je ze beter weggooien.

Inmaken

Voedsel in glazen potten inmaken

Je kunt bijna alles inmaken, zelfs vlees of worst. Het voedsel moet dan natuurlijk wel vers en onbeschadigd zijn. Fruit moet rauw verwerkt worden, groente moet rauw en geblancheerd zijn. Het is eigenlijk heel makkelijk. Leg gewassen en schoongemaakte groente of fruit in laagjes in een weckpot of een pot met schroefdeksel en doe het deksel erop. Zet de potten in een ketel en zorg dat ze elkaar niet raken. Vul de ketel met water tot de potten voor ongeveer drie kwart onder water staan en verhit de ketel vervolgens tot het water 75-120 °C is. Afhankelijk van hetgeen je inmaakt, moet het water 10 minuten tot 2 uur op deze temperatuur blijven. Als de potten daarna afkoelen, ontstaat er een vacuüm, waardoor het deksel luchtdicht vastzit. Als je erwten, bonen of chamignons inmaakt, moet je het kookproces nog een keer herhalen.

Inleggen

Voedsel in glazen potten inleggen

Als je eens iets nieuws wilt proberen, test je culinaire vaardigheden dan eens met wortels, bonen, paprika of rode bieten. Die zijn allemaal ideaal om in te leggen. Om een kilo groente in te leggen, heb je een halve liter azijn (5%) en tot een halve liter water nodig, waar je specerijen en kruiden aan toevoegt. Verhit het inlegvocht en giet het in de glazen of keramische potten, laat afkoelen, verhit het inlegvocht opnieuw en giet het over de groente. De groente moet een centimeter of 2 onder water staan. Laat de ingelegde groente vervolgens nog 4 tot 6 weken staan. Daarna zijn ze 3-12 maanden houdbaar.

Fermenting

Fermenting food in glass jars

Fermentation is an age-old method for preserving food and is used to this day to make sauerkraut. For some people, fermented foods are more digestible, for example. Enzymes and microorganisms break down the sugars in the vegetables in a multiple-stage process. This produces both the lactic and acetic acids that give fermented vegetables their typical flavour and stop them from perishing. Ripe vegetables are ideally suited to fermentation. It’s actually quite simple… before you start fermenting, you need to grate, slice or shred the vegetables. Then add the grated, sliced or shredded vegetables to a glass jar, fill with a 5% brine, and leave for a few days or weeks to pickle. If the jar remains well sealed, the fermented vegetables can keep for several months.

Reviving old food

Even when stored correctly, some foods rapidly lose their freshness and take on a chewy or dry, crispy consistency. There’s no need to throw these foods away, though. Here’s how you can refreshen old food in your stock.

Lettuce & herbs

Refreshing salad leaves and herbs

If you want to refresh wilting lettuce, simply sit it in cold water for a little while. This will make the leaves crisp again. You can also heat some firmer varieties of lettuce, such as raddichio, romaine lettuce and chicory. To revive herbs that have become limp, simply cut them as you would do it with flowers and place them in a glass with water. They’ll soon perk up again! You can also use wilted herbs to make pesto or freeze them in oil in ice-cube trays.

Carrots & co.

Putting the bite back into root vegetables

Just like lettuce and herbs, root vegetables such as carrots, radishes and beetroot just need to be given a little water to bring them back to life. However, it can sometimes take rather longer. Ideally, you should leave the root vegetables in a container with water for several hours or overnight – preferably in the fridge. Alternatively, you could wrap them in a damp tea towel. They will absorb the water and regain their crunch.

Fruit

Fruit – an exception

Overripe fruit can’t be refreshed, but you can use it in a number of delicious recipes. Brown bananas, for example, are a perfect ingredient in banana bread or as the base of smoothies – and, in summer, they’re great for making banana ice cream. You can use shrivelled apples and pears to whip up tasty jams, purées, compotes and crisps. However, if fruit is past its best, you should use it quickly before it gets mouldy.

Bread

Moisten and bake: Hard bread doesn’t need to be binned

We’ve all been there, haven’t we? That delicious baguette or bread roll we only bought yesterday has gone hard in the blink of an eye. However, that doesn’t mean you have to throw them away – you can still get plenty of value out of them. Take your dried bread, moisten it with a little water, pop it in the oven for a few minutes and, soon enough, it’ll taste almost as good as it did the day you bought it. If bread has become very hard, you can use it to make breadcrumbs.
zero-waste_slider-2_pasta_card-5.jpg

Pasta

Sauté or blanch: Making yesterday’s pasta soft again

Depending on how you store it, leftover pasta can either become watery or it can dry out. If you want to make it taste just as good the next day, simply sauté softened pasta over a medium heat. On the other hand, if your pasta has dried out, just pop it in some boiling water for a minute or two.
zero-waste_slider-2_cheese_card-6.jpg

Cheese

Hard cheese softens again in milk

If you leave cheese out on the dining table for too long, or if it gets pushed to the back of the fridge, it can soon become dry and hard. You can soften hardened cheese by soaking it in milk for half an hour or so – this eliminates the need to throw it out.

Biscuits, cakes & pastries

How apples can save snacks

Biscuits are naturally fairly dry, but they can become even drier and a little hard when stored for a long time. If you like your biscuits a little softer, simply pop a sliced apple in the biscuit tin for a few hours. The fruit will give the biscuits a little moisture and soften them up again. You can also do this with cakes and other baked goods.

What to do with leftovers? Get creative with your odds and ends

Sliced vegetables, yesterday’s potatoes, half a pudding – if you’re not careful, your fridge will be brimming with leftovers. You should always give your food a second chance, as it often allows you to get creative. Don’t throw leftovers in the bin, put them in a pan and conjure up something new. Cooking leftovers together with family and friends can be a lot of fun! 

Whatever the food, whatever the occasion, there’s always a recipe to match. For example, leftover bread, tomatoes and rocket can become a delicious panzanella. Maybe you could whip up a healthy dessert by turning leftover fruit into a smoothie or fruit salad? And that leftover sliced pepper can be combined with the half-can of sweetcorn and rice from yesterday to create a tasty veggie curry.  

Still got some soup leftover from yesterday, but not enough for a full portion? No problem! Just use it the last bit of soup as a sauce for pasta or noodles. And, if that’s still not enough, add a few chopped vegetables and maybe a little vegetable stock.

Check out our recipe ideas for further inspiration on how to use leftovers creatively.

Zero waste: Other things you can to stop food ending up in the bin


​​​​​​​
  • If you’re eating in a restaurant and your portion was too big, simply ask if you can take the leftovers home in a doggy bag. Alternatively, you could ask for a smaller portion in advance.​​​​​​​
     
  • Buying food to eat the same day or the next day? Try to choose products with a close best-before date.
     
  • Be smarter when peeling and slicing, we often put more of vegetables in the bin than we need to. Broccoli stems, for example, taste just as good as the florets.
     
  • Ever thought of making a salad out of radish leaves or baking banana peel into a cake?
     
  • Slice spring onions into rings and freeze them in a plastic bottle. You can then use just the right amount whenever you need them in future.
     
  • If you’ve opened a tin of food and only need half of it, simply decant the rest into a clean, resealable container. This will keep it fresh for longer.
     
  • Fancy holding a leftovers party? Cooking together with friends allows you to combine your odds and ends and whip up creative dishes.
     
  • Heading away on holiday but your fridge is still full? No problem! Simply knock on your neighbour’s door and offer them what you have.
