Do not swallow, but spit!
Nuts have to be eaten with all senses, because a mold infestation shows by a bitter taste. With rancid nuts, the fat contained in them is spoiled, which you can not only taste, but also smell and see, because the nut meat is then not white, but has a yellowish color. The decomposition products of rancid fats can lead to gastrointestinal upset. Mold toxins are due to the formation of aflatoxins, which can cause liver and kidney cancer in particular and are also stable to heating. Especially pistachios are more often attacked by mold, but also peanuts, almonds and Brazil nuts. Therefore, you should spit out the nuts, once it tastes bitter or spoiled.
Tips for shopping and storage
- Patchy nutshells are not inferior. In these nuts, the bleaching of the shells was dispensed with sulfur.
- For nut oils, make sure that they have not been refined, as this destroys many important nutrients.
- Avoid packs with darker looking or damaged cores.
- Do the Shake Test: If the core rattles in the shell, it is dried and old.
- Do not buy fresh nuts packaged in plastic, as they can form moisture there, resulting in mold fungus.
- For shredded nuts, pay attention to the best before date. Generally prefer to buy whole nuts, as they can be stored longer.
- Locals (hazelnuts) prefer shopping, as long transport routes increase the risk of mold infestation.
- Store nuts in a cool, dark and dry place.
