German ingredients firm J. Rettenmaier & Söhne (JRS) has entered into a co-operative agreement with an unnamed US oat manufacturer in a bid to expand its range of oat fibre products. JRS' product portfolio includes micro-fine, micro-agglomerated, bio- and dust-reduced types of oat fibre. It will also be opening a new production plant, which will have the capacity for approximately 4,000 tonnes.
