Also from the web:
"Bamboo fiber is widely used in food industries and is much appreciated as an ingredient because of its water-binding and texturizing properties in many processed food products varying from bakery products, dairy products, meat and fish products, beverages, sauces, and dressings".
So it's to be widely found in food and, no, it wouldn't put me off.
What would put me off Tesco's 'Finest' British Pork Sausages though is the appalling reviews they get on Tesco's own website!
