Root and tuberous vegetables

Starch occurs widely as a storage carbohydrate and is present in large amounts in some root and tuber vegetables. In Compositae (e. g., artichoke, viper s grass, bot. Scorzonera), inulin, rather than starch, is the storge carbohydrate. 

Boiled taro tubers are sunilat in nutritional v e to other root and tuber vegetables 167% water, 124 kcal per 100 g, and 1.9% proteinl. The nuimional value oi taro tubers is siridar to that of potatoes, except that die tain is much lower in wtamin C, The leaves are more nuliili ous than the tubers. Neither the tools nor the leaves of taro should be consumed taw, because some varieties contain potenually harmful amounts of calcium oxalate crystals. 

The photoprotection hypothesis is not without its critics, and it certainly does not account for every occurrence of anthocyanins, such as in the leaf veins, in stems and petioles, and in underground organs such as roots and tubers. Nonetheless, there is now a compelling body of empirical data consistent with a photoprotective function in the photosynthetic cells of leaves. Photoprotection might well be the primary role of anthocyanin in the vegetative shoots of many species.

According to Gustavsson et al. food commodities can be grouped into cereals roots and tubers fruits and vegetables meat, fish and seafood milk and egg. Examples for substantial products are products derived from paper, timber, particle boards, biobased plastics, biobased chemicals and for energy carriers steam, biogases, biodiesel, bioethanol. 

VEGETABLES. Almost every part of the plant used for food —leaves, stems, seeds, seed pods, flowers, fruits, roots and tubers—has been grouped under the term vegetable. For this reason, the carbohydrate content of vegetables may... 

Cassava tubers are rich in carbohydrates (mostly starch), but low in proteins and most other nutrients. The raw roots are lower in water content and higher in calories than the other leading roots and tubers. Also, the various dried forms of cassava tubers are about as rich in food energy as the common cereal flours. Nutritional deficiencies may result if cassava is the predominant food in the diet unless the missing nutrients are obtained by consuming adequate amounts of certain other foods. For example, the Brazilians, who can afford to do so, mix cassava flour with meats and vegetables. 

Fig. V-4 shows that starchy roots and tubers (Irish potatoes, cassava, and sweet potatoes) are by far the leading vegetable crops of the world.

Other belowground vegetative structures (i.e., roots and seed tuber) have only a relatively small proportion of the total carbon, though the root contribution is typically underestimated due to incomplete recovery during excavation. Thus, aboveground plant parts, in particular stems/branches,...
