Abstract
Background
In millennia, agro-industrial waste captured interest owing to its abundant availability, pollution reduction ability, low price, and lignocellulosic nature. It is important for the renewable
energy, biofuels, and biochemicals generation and is obtained from various sources, agricultural and forestry waste stream. Among agricultural residues, globally, cell wall is most important by-product of wheat processing produced in larger quantity. About 529 million tons wheat straw is generated every year in all over the world.
Objective
The core objective of the current study was to characterize the wheat straw cell wall for its nutritional and bioactive profile.
Study design
The whole research was conducted in three different phases. In first phase, nutritional composition and mineral profile of cell wall from the straw of different wheat varieties were determined. In second phase, wheat straw of different varieties was characterized for its important bioactive constituents, such as lignin, cellulose, hemicelluloses, phytosterol, and policosanol (PC) content.
Results
Results showed that straw of different wheat varieties contained 7.79–9.27, 3.92–5.10, 3.41–3.93, and 1.56–2.19 g/100 g moisture, ash, protein, and fat contents, respectively, whereas potassium, calcium, phosphorus, and magnesium were 1.16–2.06, 0.11–0.75, 0.12–0.99, 0.07–0.94 ppm, respectively. Moreover, lignocellulosic mass: cellulose 37.79–38.16 g/100 g raw material, lignin 15.65–16.11 g/100 g raw material, hemicelluloses 28.21–28.93 g/100 g raw material, was present in wheat straw cell wall and varied significantly among different varieties. In addition, phytosterol ranged from 912 to 1199 mg/kg in straw of different wheat cultivars, whilst PC from 195.02 to 237.12 mg/kg.
Conclusion
Conclusively, wheat straw cell wall was an excellent source of many important bioactive moieties especially lignocelluloses and could have functional use.
