What do your toilet cleaner and potato chips have in common

Potato chips were famously created in 1853 when George Crum, a chef, became frustrated with a customer who sent back fried potatoes for being too thick.

In his anger, and to spite the patron, Crum sliced the potatoes paper thin, fried them and unintentionally became the creator of the potato chip we know today.

然而，由于那些卑微的开始，很多已经发生了变化。日益增长的需求和技术进步在其他方面导致了在生产薯片生产中的化学品。

仔细的监控

One of the chemicals is sodium bisulfite, which is used to inhibit bacterial growth on fruits and vegetables, some seafood and wine.

It is also found in toilet cleaner. Yes, that’s right, toilet cleaner. Sodium bisulfite is used in most toilet cleaning agents and dishwasher products, but in a larger quantity than found in potato chips.

Sodium bisulfite works by releasing sulphur dioxide gas, which inhibits bacterial growth while preventing discoloration caused by chemical reactions. Its use in potato chips is to increase their shelf-life and bleach out discolouration.

When a chemical like sodium bisulfite is used in pharmaceutical preparations, personal hygiene products or as a food additive, it needs to be carefully monitored.

Is it harmful?

In potato chips, where it’s found in microscopic quantities, sodium bisulfite is safe.

The US Food and Drug Administration (FDA), however, stresses that sodium bisulfite must still be “used in accordance with good manufacturing practice”.

It can however not be used on (uncooked) fresh produce or be used in any foods that contain vitamin B1 as the sodium contained in the chemical destroys it.

虽然h the FDA recognises sodium bisulfite as a safe substance, there have been cases where it has caused strong adverse reactions in people.

Despite the potential risks involved, a satisfactory substitute has not yet been found.
