With a peanut allergy, the label is a safety document — and a missed 'may contain' line has real consequences. Peanut also appears as groundnut, arachis oil and in some 'mixed nut' blends.

PickEat checks every ingredient and precautionary statement and gives you a clear safe / not-safe verdict before you buy.

Spotted on a label

Satay sauces, some praline fillings and an unspecified 'vegetable oil' on lower-cost products are common places peanut hides under a different name.

With a peanut allergy, the label is a safety document

A peanut allergy isn't a preference or an intolerance — for many people it carries the risk of a severe, fast-moving reaction, and even trace amounts can be enough. That turns every unfamiliar product into a careful read, and the mental load of doing that for every item, every shop, is real.

The legal allergen rules help: in most countries peanut must be emphasised in the ingredient list. But emphasis only works if you spot it, and busy packaging, long lists and small print make misses easy — exactly the moments a scanner is built to catch.

The names and hiding places of peanut

Peanut doesn't always say 'peanut'. It appears as groundnut and as arachis or arachis oil (its botanical name), and it's a common component of mixed-nut products and certain praline and nougat fillings. Refined peanut oil is sometimes tolerated and sometimes not, which is a decision to make with your allergist — but you need to know it's there first.

Some cuisines use peanut heavily and in non-obvious ways: satay sauces, some Thai, Chinese and West African dishes, and 'secret ingredient' sauces. On lower-cost products, an unspecified 'vegetable oil' can also be a flag worth checking. PickEat reads for all of these so the hidden ones don't slip past.

'May contain' and cross-contact

Beyond the recipe itself, cross-contact during manufacturing is a major risk. Precautionary statements like 'may contain peanuts' or 'made in a facility that handles peanuts' tell you a product wasn't made in a peanut-free environment — and for a serious allergy, that warning matters as much as the ingredient list.

This labelling is voluntary and inconsistent, so it's easy to overlook. PickEat surfaces these statements clearly rather than leaving them in the small print, helping you make a safe decision instead of an accidental one.

Building a routine that lowers risk

Managing a peanut allergy safely is as much about habits as about any single product. The strongest routines are boringly consistent: read (or scan) every product every time, even ones you've bought before, because manufacturers reformulate without warning and a 'safe' staple can quietly change.

A scanner fits naturally into that routine and removes the weakest link — human attention when you're tired, distracted or rushing. It won't miss the allergen line because it's late or the print is small, and it surfaces the 'may contain' warning that's so easy to skim past.

None of this replaces your core precautions: carrying prescribed adrenaline, telling restaurants about your allergy, and following your allergist's plan. Think of PickEat as one more reliable layer of defence on the packaged products you buy — making a careful routine easier to keep up.
