HJ Heinz Co posted a higher quarterly profit on Tuesday, helped by higher prices and demand for its ketchup, soup and Classico pasta sauces, and the company stood by its full-year profit forecast.

Heinz's earned $242.3 million, or 76 cents per share, in its fiscal third quarter, ended January 28, compared with $218.5 million, or 68 cents a share, a year earlier.

The world's largest ketchup maker said revenue fell 7.5 percent to $2.41 billion, hurt by the stronger dollar.

Heinz still expects earnings of $2.87 to $2.91 a share for the fiscal year, and organic sales to grow about 6 percent.
