Businesses involved in processing and preserving potatoes prepare the crop for use in food manufacturing, catering and retail. Operations can include sorting and grading, washing, peeling, trimming and cutting potatoes into shapes such as chips, wedges or slices. Some processors also cook or blanch the product before further treatment, while others supply prepared raw potatoes for customers to finish cooking. Preservation methods may include freezing, drying, canning or packing potatoes in chilled or ambient conditions. Products can include frozen chips and other potato sides, crisps and snack ingredients, dehydrated potato flakes or granules, and peeled or cut potatoes. Processing businesses may also produce potato starch or other ingredients for use in prepared foods. Services typically cover food-grade preparation, packing and labelling in formats suited to manufacturers, wholesalers, retailers and food-service businesses.
