Molecular structures of the different types on fructooligosaccharides found in higher plants.

Fructan molecules have a history of more than 150 years and ancient peoples used fructans containing plants as food, feed or medicine. The modern history of fructans began with their discovery by Rose (1804) and known at the turn of the 20th century considerable development with Edelman's proposal concerning their metabolism in higher plant. At pre...

... are considered as carbohydrates with varying degree of polymerization (DP) and consequently varying molecular weight [6]. They consist of one sucrose molecule to which other molecules of fructose have been added (Figure 1). The term of fructans is somewhat ambiguous since the number of fructose moieties added varies. ...
Context 2
... Therefore, the simple fructans are "inulin-type' which are linear and consist of β(1-2)-linked fructose residues and found in almost all fructan-containing plant (Figure 1). ...

Sequential carbohydrate synthesis is important for plant survival because it guarantees energy supplies for growth and development during plant ontogeny and reproduction. Starch and fructan are two important carbohydrates in many flowering plants and in human diets. Understanding this coordinated starch and fructan synthesis and unravelling how pla...
The development of food products that contain value-added dietary fibre beside different classes of phytochemicals is of great interest nowadays. The present research aimed to evaluate the powder obtained from onion processing waste (OPW) for its potential use as a value-added by-product in food sector. Data on chemical and microbiological characte...

Zinc and iron are essential micronutrients for human growth, development, and maintenance of the immune system in high level. Iron and zinc are needed for psychomotor development, maintenance of physical activity, and resistance to infection. Malnutrition associated with zinc and iron deficiencies has become one of the critical problems for the world’s populations especially in large proportion of infants, pregnant women, lactating women, and elderly males. Zinc and iron deficiencies in human body are prevalent because of diet and zinc and iron status of agricultural soils and the consequential low amounts of zinc and iron in staple food crops such as rice, wheat, maize, and others. In most parts of the world with high incidence of Zn and Fe deficiency in human body, soils have low quantity of phytoavailable zinc and iron, resulting in low nutritional quality of the harvested grains. To address the occurrence of micronutrient deficiencies, plant scientists are concentrating to formulate methods to apply fertilizers and/or use plant breeding strategies to increase bioavailability of mineral elements in edible portion of crop plants. These approaches are termed “agronomic” (fertilizer based) and “genetic” (breeding based) biofortification, respectively. Biofortification, an approach to enrich micronutrient content of agriculture produce, involves strategies that spin around targeting and modulation of movement pathways (root uptake, transport, remobilization, storage, and enhanced bioavailability) of mineral nutrients, “pulling” nutrients from soil, and “pushing” them to economic parts of plants in their bioavailable forms. The three major strategies followed till date for biofortifying food crops include agronomic-based, plant breeding-based, and genetic engineering-based biofortification. To combat the drawbacks of supplementation/fortification, “biofortification” of staple food is a promising, viable, and effective route for delivering nutrient-rich food to compete hidden hunger, particularly in rural population.
