Brown & Polson corn flour is one of the oldest surviving grocery brands in Britain.
John Polson (1800 – 1843), William Polson (1810 – 1893) and John Brown (1806 -1889) merged their starch manufacturing interests in 1842 to form Brown & Polson with a factory at Thrushcraigs, Paisley.
Brown & Polson had been appointed starch manufacturer to Queen Victoria by 1853.
John Polson Jr (1825 – 1900) discovered a method for manufacturing pure starch from maize, which he called corn flour. He patented the process in 1854. It was the first corn flour to be manufactured in Britain.
Corn flour was a thickening agent for foods, advertised as a substitute for arrowroot, and used to make custard, blancmange, puddings and cakes.
The Thurscraig works were sold off in 1857, and production was relocated to the Royal Starch Works at Carriagehill, Paisley.
William Polson left the partnership in 1857 to enter into starch manufacture for himself.

Brown & Polson converted the by-product of corn flour manufacture into animal feed, which by 1884 had become a significant part of the business in its own right.
