How to improve potato skin finish

Skin finish is becoming more important as consumers increasingly demand potatoes with clean, attractive skins, particularly when buying pre-packed or loose potatoes. Tubers with surface infections such as black scurf silver scurf, powdery scab or common scab are less attractive and also likely to have a reduced storage life.

How to influence potato starch content

Potatoes are one of the most important sources of starch worldwide. Variety choice is very important and potatoes with greater than 13% starch content are required in countries such as Germany. The higher the starch content, the lower the waste.
