Buy vegetables online: Practical choices for edamame, beans and long-life side dishes

Anyone looking to buy vegetables online will find a wide selection of frozen products, tinned goods and plant-based specialities. However, shopping decisions should be based on more than product images or terms such as “natural”, “high in protein” or “freshly harvested”. The key factors are the ingredients list, net quantity, storage requirements and whether the product suits your everyday routine.

This shopping guide from the Joybuy Product Recommendation Officer explains what families, vegans, vegetarians and keen home cooks should look for when comparing products.

Common pitfalls when buying vegetables online

1. Net quantity and drained weight are confused

With tinned vegetables, the packaging often states the total weight, including water or brine. However, the drained weight is a more useful indication of how much you will actually eat. A 425 ml tin may therefore contain considerably less vegetables than the outer size suggests.

When comparing prices, you should consider the price per kilogram of the drained contents. This prevents a supposedly low-cost tin from working out more expensive because of its high liquid content.

2. “Vegan” does not automatically mean low in salt

Many vegetable products are vegan, vegetarian and lactose-free. However, the salt content can still be significant in pickled products. Ingredients such as water and salt are common in beans and pickled vegetables. Fermented specialities, such as pickled mustard greens, may have a considerably higher declared salt content.

The nutritional information provides a more objective guide than marketing claims. Check the salt per 100 g value and whether it refers to the drained product.

3. Check organic and freshness claims carefully

“Organic” is a protected designation and should be confirmed by the relevant organic seal on the product. With organic edamame or organic spinach, it is also important to check whether the product is shelled, blanched, portioned and sold frozen.

Frozen vegetables are not automatically fresher than every other product. However, they can be convenient because they can be portioned and, when stored continuously at −18 °C or colder, remain in stock for longer.

Important factors when buying vegetables online

Ingredients and allergens

For a vegan diet, it is not enough to look only at the product photo. Check the following:

  • Does the ingredients list contain only vegetables or a clearly understandable recipe?
  • Does the product contain sugar, acidity regulators or preservatives?
  • Is an allergen such as soya or mustard listed?
  • Is there any information about cross-contamination?

Edamame are young soya beans and therefore contain the soya allergen. Anyone looking to buy soya beans should take this warning into account regardless of whether the product is suitable for a vegan diet.

Storage and preparation time

The type of product determines how much storage space you need:

  • Frozen vegetables: Store at at least −18 °C; do not refreeze after thawing.
  • Tins and jars: Store unopened in a cool, dry place; after opening, transfer to a suitable container or refrigerate covered.
  • Cooked, chilled products: Maintain the cold chain and consume within the stated period after opening.

If you are short on time, cooked edamame can be served cold or gently warmed. Frozen green beans, on the other hand, must be heated thoroughly. The specific timings on the relevant packaging take priority.

Packaging size to suit your household

A 300 g pack may be suitable for a small household or as a side dish. Families and frequent users may benefit from 750 g or 1 kg packs, provided there is enough freezer space. With tinned products, the pack size should match how much you plan to use after opening.

Smaller packs are often more manageable for occasional meals. If you regularly prepare bowls, stir-fries or salads, larger quantities can be used more economically.

More useful options for your store cupboard

Anyone looking to buy green beans can choose between frozen products and tinned options. Frozen fine beans from Jeden Tag are sold without additives and require around 12 minutes on the hob or around 9 minutes in the microwave. Tinned options such as Bonduelle Extra Fine Green Beans or Küstengold Fine Cut Green Beans, on the other hand, can be used straight away and do not require freezer space.

For larger households, peas with carrots are also available in various tin sizes. Buying seaweed is particularly worthwhile for salads, soups and rice dishes; with Green-Deer products, you should take the comparatively high salt content into account. If you are looking for a larger frozen portion, you can also choose cooked Mooijer-Volendam edamame in a 1 kg bag. Store at −18 °C or colder.

FAQ about buying vegetables online

How long do tinned vegetables keep after opening?

This depends on the product. According to the product information, some tins should be consumed within one day, while others should be used within two to three days. After opening, they should be refrigerated and, wherever possible, transferred to a suitable sealable container.

What is important when buying frozen vegetables?

Look for undamaged packaging, the required continuous storage temperature of −18 °C or colder, and the instruction not to refreeze the product after thawing. Preparation times vary depending on the type of vegetable and the product.

Where can you buy edamame and how are they used?

Edamame are available online as shelled beans, whole pods or already-cooked soya beans. They work well in salads, bowls, soups, stir-fries and snacks. Because they contain the soya allergen, check the ingredients and allergen information before buying.
