    Eating zucchini raw - harmless or risky?

    Zucchini is a mildly spicy dish that is rich in vitamins and low in calories. However, the many advantages do not give the green light for carefree raw consumption.

    What are cucurbitacins?

    Cucurbitacins are poisonous bitter substances that can be found in zucchini and other cucurbits. Even small amounts can cause severe poisoning in humans, such as vomiting, diarrhea, stomach cramps and circulatory failure. Unfortunately, these bitter substances are extremely heat-resistant and very difficult to dissolve in water. This is what makes cucurbitacins so dangerous, because conventional cooking doesn't destroy the toxins. So it doesn't matter whether you eat zucchini raw or cooked. With a high concentration of bitter substances, health problems are inevitable.

    When and how are raw zucchini safe?

    Organic zucchini can also be processed raw with the skin on

    For zucchini from the supermarket, the all-clear can be given with regard to toxic bitter substances. The delicious green fruits have a good laugh, because they grow splendidly without cucurbitacins. The toxic ingredients have been bred out of all varieties, so you can also eat yellow courgettes raw. Nevertheless, a shadow falls on raw zucchini, because contamination by pesticides makes eating it with the peel a risky undertaking. All fruits that do not come from certified organic cultivation are affected. The following tips explain when and how you can eat raw zucchini without worrying:

    • commercial zucchini: peel, eat raw or snip uncooked into the salad
    • Organic zucchini: wash thoroughly and eat raw with the skin as a salad, on bread or with a dip

    Organic zucchini are clearly the way to go if you want to eat the delicious fruit vegetable raw. Certified organic farmers consistently refrain from using pesticides. Conventional zucchini from the store shelf often comes with a stressed skin. In the worst case, unpeeled enjoyment is punished with tormenting flatulence. However, most of the vitamins and trace elements are located directly under the peel. If you can't bring yourself to peel a zucchini, you should at least wash the peel carefully and scrub it with a brush.

    Eating raw is dangerous

    Zucchini isn't the only vegetable that can give us a hard stomach when eaten raw. Caution is also advised when eating potatoes, tomatoes, beans and other delicacies from the vegetable garden raw. Topping the list of culinary killjoys are raw potatoes and green tomatoes, which are high in the toxic solanine. Rhubarb can cause an upset stomach if the sweet and sour sticks are eaten raw in large quantities. In this case, toxic oxalic acid is the culprit. Eating legumes raw is dangerous because the phasin they contain can cause severe intestinal discomfort and nausea. The good news is: unlike cucurbitacine, solanine, oxalic acid, and phasin dissolve in pleasure when cooked.

    Risk of self-cultivation - tips for hobby gardeners

    Homegrown zucchini cannot be eaten raw without hesitation

    Attention hobby gardeners. Mixed culture with pumpkin makes every zucchini a wobbly candidate for worry-free raw consumption. This note is not an exaggerated horror scenario, but is based on tangible practical experience. The most common causes of a dangerous toxin content in courgettes are crossing or backcrossing with other cucurbits. Furthermore, cucurbitacine levels skyrocket during stress from heat or cold. Rarely, spontaneous changes within a zucchini plant set the toxic process in motion. The following tips sum up how hobby gardeners can professionally prevent the risk of poisonous zucchini:

    • Refrain from breeding experiments: Always grow zucchini with certified seeds
    • Do not grow ornamental gourds: Avoid crossing and backcrossing by not growing ornamental gourds
    • Avoid drought stress: Water zucchini regularly, early in the morning or in the evening when it is hot in summer
    • cold protection: cover zucchini plants with fleece overnight during cold spells

    A documented death in 2015 shook up the home gardening community, drawing attention to the issues of backcrossing, unwanted crossing of zucchini with other cucurbits, and growing stress. The unfortunate zucchini lover pays with his life for eating a casserole. Investigations revealed that the zucchini used came from a hobby garden and contained a high concentration of bitter substances.

    Reports of serious zucchini poisoning increased this year as desert-like heat and drought gripped the country. As a result, the Bavarian State Office for Health and Food Safety warned against eating home-grown zucchini and pumpkin without tasting it first.

    tips

    Popular types of vegetables do not show that they belong to the cucurbit family. In addition to Hokaido, Turkish turban and other garden pumpkins, cucumbers and melons are also part of the multi-faceted pumpkin family. This is accompanied by the risk of a toxic cucurbitacine concentration as a result of backcrossing, crossbreeding and the stress of self-cultivation in the hobby garden.

    Bitter taste reveals toxins

    When zucchini tastes bitter, alarm bells ring. Bitter taste is a sure sign of cucurbitacins. Perfect zucchini, on the other hand, spoil the palate with a mildly sweet aroma. If you want to be on the safe side, you should taste a piece of each fruit before feasting. Basically, it makes sense to taste a zucchini from a hobby garden. How to do it right:

    1. Wash zucchini with lukewarm water
    2. Cut off a piece with a kitchen knife
    3. put it in your mouth and bite
    4. Spit out bites at the slightest sign of bitter taste
    5. Dispose of questionable leftovers in the organic waste bin

    If children have not yet reached primary school age, their sense of taste is usually still developing. This entails the risk that a bitter aftertaste of zucchini raw vegetables will go unnoticed. We recommend that you act as a taster for the offspring before you serve the delicious dish.

    In horticulture, backcrossing occurs when a flowering plant is pollinated and fertilized with the pollen of a plant belonging to the generation of its direct descendants.

    tips

    A few criteria guarantee a premium quality zucchini harvest. Use certified seeds for sowing from April to late May. Regular watering and organic fertilizers are mandatory. Harvest the fruits when they are young and tender, measuring 10 to 20 centimeters in length. Overripe courgettes tend to produce more cucurbitacins, which can be recognized by their bitter taste.
