The Good Food Group-owned business is launching a range of fruit fillings/compotes into the multiples next month and also plans to re-brand its jams.
The NPD and revamp are the first significant innovations for the brand in four years and also the first initiatives from Martin Tilney, the former commercial director of PepsiCo, who left in 2007 and joined Streamline this January.
The new compotes (rsp: £1.89 for 500g), which come in Fruits of the Forest, Morello Cherry and Apple & Blackberry flavours, could be used as a filling for pies or for pouring over yoghurt and porridge, Tilney said.
"Buyers have been saying home baking needs some innovation and news, which this is," said Tilney. "It is a new area and we think there will be good consumer demand for it."
Since January, Streamline had been pouring resources into marketing and NPD, he added.
"It has woken up to the fact that if it wants a better and bigger branded business it has to start investing behind it," he said. "That's why they have employed me to turn it around and make the company more strategic."
The only competitor range was Hartley's Fruit Fillings, said Tilney, and Streamline's Tetra Pak packaging and high fruit content would set it apart.
The three compotes contain about 50% fruit and no added colours or flavours. They also have a one-year shelf life.
An advertising campaign for the range will launch this autumn.
