Heinz will have to change their sauce bottles following the death of Queen Elizabeth II.
Around 800 food and drink brands will now have to remove their Royal Warrants from items.
The Royal Warrant allows companies to use the royal coat of arms on products and in marketing.
And in return, the firms supply their goods and services to the Royal Family.

Royal Warrants have become void following the death of Queen Elizabeth II

The royal coat of arms is displayed on the top and front of every Heinz ketchup bottle in the UK.
But following the death of the former monarch, the warrants become void, meaning all companies must drop the coat of arms.
It is understood that all companies will have to reapply from King Charles III.
Firms will have to prove they supply “products or services on a regular and ongoing basis to the Royal Households of grantor/s for not less than five years out of the past seven".
While the Royal Warrant Holders Association added: “Amongst other things, applicants are also required to demonstrate that they have an appropriate environmental and sustainability policy and action plan.”
Cadbury, Coca-Cola and Pimm’s have also been affected.
Premier Foods, Unilever, British Sugar and Martini had also been granted a warrant under Queen Elizabeth II.
