“…Sunn hemp belongs to the Fabaceae family and is a substantial source of lignocelluloses, thus, it has significant economic value. Usually, the stem is used to collect the bast fibre and has been found to have a fibre content of 13% of the dry weight (Rawat et al, 2023 andNarayana et al, 2023). Jadhav et al (2022) investigated the mechanical and thermal effects of incorporating sunn hemp fibre into the epoxy composites.…”

In this study, a microcrystalline cellulosic biopolymer (MCB) made from Pisum Sativum (green pea) pod waste via a modified thermo‐chemical process, and Crotalaria juncea (sunn hemp) fibre was used to create environment‐friendly polyester composites. The main objective was to synthesise the MCB from domestic waste and characterize how the addition of hemp alters the strength of the polymeric composite. The MCB was synthesized using green pea pods. The sunn hemp fibres were used in mat form in this study. The composites were made using the hand layup method and post‐cured at 110°C for 2 h. The results showed that the addition of sunn hemp fibre and MCB increased the mechanical properties. Similarly, the highest observed fatigue life count for the composite designated PSC3 (2.0 vol.% MCB) was 30862 at 30% ultimate tensile stress. Similarly, the composite PSC3 had the maximum penetration resistance with an absorbed energy of 14.2 J. Moreover, the addition of silane‐treated cellulose and fibre provided an improved storage modulus of 6.8 GPa for the PSC3 composite, confirming the improved fibre‐matrix fibre interaction and increased toughness. The scanning electron microscope images revealed improved fibre‐matrix correlation. These eco‐friendly composites with better load‐bearing capabilities could be preferred in automated door panels, defence toolboxes, and home interior decoration applications.

“…Sunnhemp (Crotalaria juncea L.) is widely cultivated tropical Asian plant of the legume family (Fabaceae). Sunnhemp plant can be grown in adverse conditions like droughts, alkalinity and salinity and is mainly used for ber production and as a fodder crop (Rawat & Saini, 2023c). Besides this, sunnhemp seeds possess excellent nutritional value.…”

Sunnhemp protein isolate (SHPI) was prepared by utilizing alkaline extraction acid precipitation method. SHPI-dextran conjugates (1:1 w/w ratio) were prepared by dry heating method with Maillard reaction at 60°C for 0, 1, 3, 5, 7, and 9 days of incubation at 79% relative humidity. The functional properties of SHPI-dextran conjugates like solubility, emulsifying, foaming, water and oil binding capacities, dispersibility, and gelation were improved as compared to pure SHPI. Increment in browning index values of SHPI-dextran conjugates were observed with increase in Maillard reaction time. Conjugated SHPI reduced the percentage of α-helix and increased the content of β-sheet, β-turn and random coils content. FTIR spectroscopy confirmed the formation of covalent bonds between SHPI and dextran via Maillard reaction. XRD analysis indicated both semicrystalline and amorphous structure of SHPI-dextran conjugates as the incubation time was increased from 0 to 9 days. Decreasing trend in the values of surface hydrophobicity values were found with increase in incubation time. Free and total sulfhydryl content of SHPI was increased after conjugation with dextran up to 5 days and thereafter decreased. Incubation time of five days at 60°C and 79% RH was optimized on the basis of improvement in functional characteristics and extent of Maillard reaction time. Overall, the present study showed that conjugation of sunnhemp protein isolate with dextran successfully improved the functional characteristics of SHPI.
