Heinz is looking to intensify its marketing investment over the next two years, according to CEO William Johnson.

The US food giant plans to spend US$100m over the next two years on marketing its key brands and a raft of product launches.

"We plan to continue supporting our product launches with substantially increased marketing investment," Johnson said.

Heinz's investment in R&D will also rise in double-digit percentage terms this year.

Earlier this week, Heinz told shareholders that it expects operating profit to jump 14% during the first quarter of the year.

Heinz said the rise in profits would come on the back of a 9% rise in sales. Heinz said it saw "double-digit" sales growth from its ketchup, beans and soup portfolio.

Heinz has unveiled a raft of new products in recent months, particularly in the UK.

This week, the company launched a new format to its flagship baked bean brand with the arrival of a four-pack "yoghurt pot" version of the product.

Earlier this month, Heinz released what it dubbed three "groundbreaking" soup ranges in the UK.

And last month, Heinz launched a line of hand-held mini-meals under the Weight Watchers Smart Ones brand called Anytime Selections.
