Nutritional value and value-added products of potatoes

Abstract

Globally, potato (Solanum tuberosum L.) shares a major part of our daily diet. Due to frequent consumption, potatoes and their processed products have nutritional significance for human health. Potatoes are carbohydrate rich foods containing plenty of dietary fibre, proteins, vitamins, minerals, bioactive molecules, phytochemicals, anthocyanin, carotenoids, and metabolites that have beneficial effects on human health. Among the processed products of potatoes, chips and French fries are most popular, beside this, various frozen products such as mashed potatoes, hash browns and puffs, dehydrated potatoes, and starch are also available in the market. In the past few years, ICAR-CPRI Shimla has developed several potato-based novel value-added products such as potato cookies, potato millets cookies, halwa premix, semolina, porridge, gulab jamun, jalebi, muffins, and many more, which are rich in dietary fibre, protein, vitamin C, and potassium. The low sodium content and gluten-free composition make these products also suitable for celiac/wheat allergic and hypertensive populations. This article provides a better understanding of nutritional significance and an overview of new dimensions of value addition in potatoes.
