US sauce maker HJ Heinz has backed its fiscal 2003 earnings outlook, citing the good performance of its ketchup brand. The company, which recently sold off its underperforming tuna, pet food and baby food units to US food company Del Monte Foods, is now focusing on its primary condiments and sauces business, with particular focus on developing its Heinz Ketchup brand. In recent years, Heinz has introduced coloured ketchup, organic ketchup and a range of packaging innovations, such as its Easy Squeeze! upside down ketchup bottle.
