A lemon is a low-acid fruit

Lemon oil helps you with depression and low moods

The essential lemon oil can also be extracted from the peel of the lemon, which now contains numerous active ingredients from the lemon peel in highly concentrated form. The lemon oil can be used for cooking, in the fragrance lamp or as a body oil mixed with a base oil.

When used therapeutically, lemon oil can improve the ability to concentrate and help with depression and depression. The latter apparently partly better than the common antidepressants - as you can read in our article about the effects and uses of lemon oil.

So you can use lemon juice in the kitchen and around the house too

If you would rather only use lemon juice, you will find all the possible uses of the sour all-rounder in our articles about lemon juice. The lemon juice can be used as a natural remedy, but also serve as a valuable helper in the household, e.g. B. as a descaler, grease stain remover, disinfectant or as a metal polishing agent.

How to store lemons

Store lemons in a dark place at temperatures between 10 and 15 degrees Celsius. Then they last for up to 5 months. But even at room temperature, the fruits can be stored well for at least a week. However, it is better to keep the cold-sensitive lemon away from the refrigerator, as it loses its aroma there.

Green and Yellow Lemons: The Difference

If you bought a green lemon in the health food store in the fall or early winter, it would turn yellow in the refrigerator after a few days. Because lemons need cool nights to turn yellow. In Spain and Italy, however, it often doesn't get cool enough until January or February, so the lemons are naturally green until late autumn.

However, since the consumer associates green with unripe and would rather buy a yellow lemon, green lemons are fumigated with ethylene (a ripening gas) in conventional stores so that they turn yellow. Paradoxically, if the fruit is picked too early, it can be unripe fruit that now tastes bland despite the change in color, because lemons - just like oranges and other citrus fruits - no longer ripen once they have been harvested.

What to look for when buying lemons

When buying lemons, make sure that the skin is intact and has no moldy spots. You can recognize ripe lemons by their particularly intense fragrance, their peel gives way slightly when pressed. Unripe fruits taste more sour and tart compared to ripe ones.

In any case, you should rely on organically grown lemons, because conventionally cultivated fruits are almost always treated with pesticides and / or preservatives.

Why organic lemons are better

Organic lemons usually do very well in tests: The environmental protection organization Global 2000 tested twelve organic fruits for pesticides in 2016 and all of them were completely free of residues (26).

The situation is completely different with lemons from conventional cultivation: According to analyzes from Chemical and Veterinary Investigation Office Stuttgart In 2016, all 22 samples had multiple residues, and one sample even exceeded the maximum permitted level (27).

This was chlorate, which is actually no longer even approved in the EU and, according to a statement by Federal Institute for Risk Assessment can lead to iodine absorption being inhibited. Since iodine is an important trace element, especially for the thyroid, people with thyroid disease, iodine deficiency or newborns and children who urgently need sufficient iodine for their development suffer from such residues (28).

"Untreated" does not mean "uninjected"

Do not rely on labels such as "untreated" or "peel edible", as these refer exclusively to the treatment of the peel with preservatives after the harvest! Of course, these fruits can still be splashed. You can find more interesting information under: Pollutants in citrus fruits

Lemons: varieties and growing areas

Lemons - both organic and conventional lemons - are grown in subtropical regions around the world and are available all year round. The most important European growing countries are Spain and Italy. There are countless types of lemon that differ in size, shape, thickness of the skin and juice content. In the trade, however, varieties such as Eureka, Lunario and Lisbon are mainly offered.

Not all varieties taste the same sour. There are also sweet variants, such as the low-acid ones Sfusato Amalfitanowhich is grown exclusively on the Amalfi Coast in Italy. Limoncello liqueur is made from it or it is simply sliced ​​thinly and served in combination with olive oil, garlic, mint and salt.
