“…In groundnut flour, bioaccessibility of iron was 1.25% and that of zinc was 11.3%. Our results confirm the findings of Reddy & Hotwani (1993), who have reported that the ionisable iron in groundnut flour is comparatively lower than all other oilseeds. Lower bioaccessibility of iron in groundnut flour can be attributed to the presence of higher phytate, tannin and oxalate content than soya.…”

Summary In developing countries, iron and zinc deficiencies are mostly attributable to poor bioavailability of iron and zinc. The study aimed at enhancing the bioaccessibility of minerals in high‐phytate oilseed and cereal flour mixes by activating the intrinsic phytase of wheat flour. The flour mixes were fortified with iron and zinc separately for comparison. The flour mixes were incubated at optimum conditions of temperature and pH for phytase activation. Phytase activation enhanced bioaccessible iron by 43–162% in native and 40–168% in fortified wheat–soya, 83–192% in native and 97–240% in fortified wheat–groundnut flour mixes in relation to control flour mixes. Bioaccessible zinc was enhanced by 87–183% in native and 30–113% in fortified wheat–soya, 31–65% in native and 61–186% in fortified wheat–groundnut flour mixes. Endogenous phytase activation was effective in enhancing bioaccessibility of iron and zinc in native and fortified flour composites economically.

“…Dialysability of iron representing bioaccessibility increased by almost twofold from defatted flour to protein isolate. The per cent dialyzable iron in nigerseed protein isolate is higher than soya protein isolate and ionisable iron of most of the oilseeds (Reddy & Hotwani, 1993; Hegde et al. , 2009).…”

The investigation aimed at preparing protein isolate from niger seeds and determining its nutritional profile, functional properties and antioxidant potential. Niger seeds with 25.5% protein, 30% fat and 21.8% fibre were used for preparation of dehulled, defatted niger seed flour (DNF) and protein isolate (NPI). Protein content of DNF was 53.8% and NPI was 85.7%. Minerals, crude fiber and carbohydrate content reduced from DNF to NPI. In vitro protein digestibility, iron and zinc dialysability increased significantly from DNF to NPI with a corresponding decrease in fibre, tannin and phytate. Water and fat absorption capacity (FAC) was higher in DNF and foaming and emulsification index was better in NPI. Polyphenol content of NPI was higher than DNP. NPI exhibited significantly higher free radical scavenging ability and metal chelating ability, hydroxyl radical scavenging activity was comparable to DNP. Studies on organo-leptic evaluation and utilisation of NPI as a protein source in food formulations are warranted.

“…They found that pesticides significantly reduced the zinc content but increased the calcium and potassium contents. Additionally, endosulfan had a more pronounced effect on altering mineral element contents compared to malathion [ 55 ]. The probable reason for this is that pesticides, as exotic stressors, cause a reduction in rice stomatal opening, which in turn results in a decrease in photosynthetic rate and organic matter production, thereby reducing the fat and carbohydrates stored in rice gains [ 56 , 57 , 58 , 59 , 60 ].…”

Chlorantraniliprole is a broad-spectrum insecticide that has been widely used to control pests in rice fields. Limited by its low solubility in both water and organic solvents, the development of highly efficient and environmentally friendly chlorantraniliprole formulations remains challenging. In this study, a low-cost and scalable wet media milling technique was successfully employed to prepare a chlorantraniliprole nanosuspension. The average particle size of the extremely stable nanosuspension was 56 nm. Compared to a commercial suspension concentrate (SC), the nanosuspension exhibited superior dispersibility, as well as superior foliar wetting and retention performances, which further enhanced its bioavailability against Cnaphalocrocis medinalis. The nanosuspension dosage could be reduced by about 40% while maintaining a comparable efficacy to that of the SC. In addition, the chlorantraniliprole nanosuspension showed lower residual properties, a lower toxicity to non-target zebrafish, and a smaller effect on rice quality, which is conducive to improving food safety and the ecological safety of pesticide formulations. In this work, a novel pesticide-reduction strategy is proposed, and theoretical and data-based support is provided for the efficient and safe application of nanopesticides.
