Potato (Solanum tuberoum)

The potato plant firstly cultivated for domestic purposes three to save thousand years ago in South America and is cultivated all around the world. Now potato grown in 160 country and use all over world. Potato ranks 3rd after wheat and rice in term of consumption.in Pakistan potato cultivated all around the year from plain to hilly areas. It is cultivation done by tuber. The dry mass and protein per unit growing of potato is higher than cereals crops. Potato and Potato processed food items could replace the cereal products and Potato produce food par unit water than any other crop up to seven times more efficient in water use with respect to cereal crop and play a vital role in food security for millions of the proper. Global production more than fifty present comes from developing countries.  The potato tuber has remarkable adoptability and nutritional provide a plenty nutritious component of diet excellent vitamin C, potassium and fiber. In potato carbohydrate’s found in the form of starch round about 10-30% of the total fresh mass. Potato starch packed in to starch granules that contain two shape amylose and amylopectin with the ratio 1 : 3 respectively.

The cooking process cause the loose its crystalline properties and make the starch to gelatinize. Its contain potassium more the banana the value of potassium on par day serving is recommended can found in a medium potato. Vitamin A deficiency is widespread and β-carotenoid is a good source of vitamin A, Vitamin C water soluble that act as an antioxidant helps to prevent the caller damage.
