The physical characteristics such as size, shape, surface area, true density, bulk density and porosity of the potato are mainly related to heat and mass trans- fer. Potato in bulk is a heterogeneous mass with widely varying physical properties.
What are the chemical properties of potato?
Starches were isolated and characterised from 10 potato cultivars grown under the same conditions (with a commercial starch for reference). The chemical composition revealed some differences amongst the starches with protein ranging from 0.30% to 0.34%, amylose 25.2% to 29.1% and phosphorus 52.6–66.2 mg 100 g−1.
What is the chemical composition of a potato?
By weight, the average russet potato is about 78.3 percent water. After water, starches and sugars compose the bulk of the potato's chemical content at about 18 percent. Non-digestible carbohydrates--or fiber--in the form of cellulose and pectin make up another 0.4 percent of the potato.
What is the shape of potatoes?
Potato tuber shape is a morphological trait which displays continuous variation. Tuber shape ranges from compressed, round, oval and long.
