“…13 To further increase the mechanical properties of PVA/S-based films, reinforcement of various microand nanofillers such as cellulosic fibers, synthetic fibers, nanofibrils, and nanocrystals with PVA/S matrix can be approached. [14][15][16] Recently, starch nanocrystals (SNCs) have received great attention due to their biocompatibility, availability, low cost, and compounded with many different kinds of polymer matrices. 17,18 Condes et al reported that the incorporation of SNCs with amaranth protein resulted in an increase in the mechanical properties of nanocomposite films.…”

In the present work, corn starch was grafted with oleic acid in the presence of redox initiators. Starch nanocrystals (SNCs) were synthesized using acid hydrolysis method and nanocomposite films were prepared by incorporation of SNCs into polyvinyl alcohol/starch (PVA/S) and PVA/grafted starch (PVA/GS) matrix, separately. It was observed that SNCs exhibited a platelet-like shape and in the size range of 200 nm. The increased crystallinity of SNCs indicated the removal of the amorphous and waxy region after acid hydrolysis of starch. Scanning electron micrographs of nanocomposite films showed good dispersion of SNCs within the PVA/GS matrix compared to the PVA/S matrix. The tensile strength of the nanocomposite films increased significantly with the reinforcement of SNCs into PVA/S matrix. Water uptake (%) of PVA/GS nanocomposite film decreased by 38.25% compared to the PVA/S nanocomposite film. Reinforcement of SNCs with PVA/S matrix improved the biodegradability of the films and was higher than PVA/S film. PVA/S nanocomposite film showed 32.4% weight loss after 120 days of soil burial degradation test. Thus, the obtained nanocomposite films can provide a potential alternative to the synthetic and nondegradable packaging films used worldwide.

The current study investigates replacing water (2.5–15%) in whole wheat pasta with groundnut oil/candelilla wax (GNO/CW) oleogel. To assess the impact of incorporating GNO/CW oleogel at varied concentrations, both uncooked and cooked pasta samples are physicochemically characterized. The water absorption capacity of oleogel‐containing cooked pasta samples is found to be lower. Microscopic analysis of the surface of pasta samples (uncooked and cooked) exhibits considerable changes in their topology as the composition varied. Black patches on the cooked pasta samples are observed when the GNO/CW oleogel replacement is on the higher side (10% and 15% replacement), implying the formation of starch–lipid complexes. FTIR analysis is performed to analyze the changes in functional groups and molecular bonds. There are no major changes in the water and the starch regions of pasta samples (uncooked and cooked). The addition of GNO/CW oleogel in the pasta samples enhances their stiffness. Additionally, the pasta samples exhibit viscoelastic properties. Therefore, the incorporation of GNO/CW oleogel into the whole wheat pasta dough can change the physicochemical properties of both uncooked and cooked pasta samples.
