Opis

Potatoes (Solanum Tubersum, L) belongs to family Solanaceae, it is called potato or Irish potato. Egypt is a leader country in cultivating and exporting potatoes in the area of Middle East. Now in Egypt a great part of potato crop directed to chips production to supply the Egyptian and foreign market throughout the year. The chipping companies complain about the discoloration of the product due to the high reducing sugars even after a considerable storage time after harvesting. Factories in most cases use the available varieties of potato in the market without recognizing if it is suitable for chips production or not. This case leads frequently to bad quality and low quantity of the end product. The acceptability of potatoes for processing as chips is largely dependent on the color of the end product. Color is directly related to the quantity of sugars in the tuber. The quantity and composition of sugars in tubers is dependent on cultivar, stage of maturity, occurrence of stress, and handling and storage management practices. Regulation of sugar levels in tubers by proper production and storage management practices is essential to ensure acceptable processing quality.
