How does food processing affect the GI of potatoes?
Potato varieties, maturity level, starch structure, food processing techniques and composition of the meal contribute to the GI of potatoes. Domestic boiling, baking, microwave cooking, oven cooking, extrusion and frying result in different degrees of gelatinization, and the crystallinity of starch in potato.
How are potatoes processed in the United States?
Among all potatoes, 26% were consumed as fresh or without processing, whereas the remaining 74% were utilized in some or other forms of processing. Frozen potatoes (40%) were the most consumed processed potato product in the processed category in the USA.
How does food processing affect the nutritional content of food?
A variety of things can happen during the growing, harvesting, storage and preparing of food that can affect its nutritional content. Processes that expose foods to high levels of heat, light or oxygen cause the greatest nutrient loss. Most plant crops are produced with the aid of fertilised soils.
How are potatoes used in the food industry?
In addition potatoes are used for seed and animal feed. The post-harvest technology will assist in improving production and tuber use. The objectives to advance the crop involve greater productivity, lower production costs and better storage conditions. Long term potential of potato use is based on derived products.

What causes the starch in potatoes to soften?
In particular, dur- ing potato cooking, starch gelatinization occurs, which affects the palatability, digestibility and causes softening of the raw starch matrix. Heat is transferred into the potato tubers primarily by con- vection from the heating media (water) (Barba, Calabretti, Amore, Piccinelli, & Rastrelli, 2008).
How does the potato help in diet diversification?
Thus, the potato already plays a role in diet diversification in many countries. However, where other staple crops are available to meet energy requirements, potato should not replace them but rather supplement the diet with its vitamins and mineral content and high quality protein.
How are raw potatoes prepared for human consumption?
However, preparing and serving potatoes with high-fat ingredients raises the caloric value of the dish. Since the starch in raw potato cannot be digested by humans, they are prepared for consumption by boiling (with or without the skin), baking or frying.
