Plenty of people each year fall foul of airport regulations. No more than 100ml of liquids can be taken in hand luggage – that means tins and jars of food, including anything from baked beans to maple syrup and jam to chocolate spread.

London City Airport has revealed the most common food items confiscated from passengers who haven’t read the rules and the top five confiscated items are jam or marmalade, Marmite, Golden Syrup, Nutella and Heinz Baked Beans.

However, the airport does not let the grub go to waste and has donated 300 items collected between January and March 2015 – with a combined value of more than €1,200 – to a local food bank.

Branded items bought in London’s West End from stores such as Harrods and Fortnum & Mason have proved very popular in security’s vaults – dozens of jars of ‘posh’ jams, marmalade and lemon curd from the two retailers were collected in the first three months of the year, but are now on their way to helping those in need.

“While we are very pleased to be able to find such a good home for confiscated items, we urge anyone flying from our airport to consider the rules when buying souvenirs so that they are not disappointed at security,” said a spokesperson for London City Airport.

“All liquids in hand luggage must be under 100ml and carried together in one, sealed, clear plastic bag, including any food items that may be classed as a paste. Anything larger must be checked in to make sure it gets to the other end.”
