Potato fibres, a by-product from the potato starch industry, holds a lot of water. Due to this, the fibres become heavy and bulky, making it difficult to process, store and transport them.
In this thesis is shown that enzymes able to break down non-cellulosic polysaccharides, namely arabinogalactan, pectin and xyloglucan, is advantageous to decrease the water retention of potato fibres. Furthermore, it is shown that applying these enzymes before the starch is collected, helps to recover more starch from being lost in the fibre by-product.

Therefore, enzymatic pre-treatment of potato fibres is advantageous for the potato starch industry and makes handling of the by-product more easy.
