Feather keratin hydrolysate (FKH) was effectively incorporated into the nanofibers, and the antioxidant activity of the nanomaterials was confirmed.

Furthermore, the functionalized nanofibers showed low hemolysis rates (up to 3%) suggesting they are safe materials when considering the acceptable hemolysis threshold for biocompatible materials (below 5%).

Tamarind kernel powder was subjected to proximate and physico-chemical analysis. The effect of the TKP content (10, 20, and 30 wt%) and plasticizers (glycerol and polyethylene glycol) on the blending of PBAT was investigated. These bioplastic films were subjected to compatibility, mechanical, thermal, water barrier, UV-vis spectroscopy, and overall migration and biodegradation studies. From proximate analysis, the major constituent of TKP powder was found to be xyloglucan, accounting for 66.8% of the total carbohydrates. FTIR analysis showed that TKP has strong interactions with PBAT. SEM micrographs revealed that 30% of the TKP films had an increased roughness and uniform dispersion, which was found in the presence of plasticizers. UV-visible spectroscopy analysis showed that transmittance decreased with an increase in the concentration of TKP. The tensile strength of TKP inclusion films decreased with an increase in concentration, whereas their modulus enhanced, showing increased film stiffness.

The cold plasma treatment can substantially alter the structural and functional properties of egg white protein. The core of the review lies in the multifaceted effects of cold plasma treatment on egg white proteins, encompassing structural transformations elucidated through SDS-PAGE, Fourier transform infrared spectroscopy, nuclear magnetic resonance, and circular dichroism. Microscopic, rheological, and spectroscopic analyses offer a comprehensive understanding of the various modifications induced by cold plasma treatment. Cold plasma treatment caused alterations in the conformation of the protein structure, changing its solubility, emulsifying, foaming, and gelling properties. These modifications improve protein functioning, rendering them more appropriate for a range of dietary applications. Cold plasma treatment was found to enhance the antibacterial properties of egg white protein by increasing its capacity to suppress the growth of harmful microbes such as <em>Escherichia coli</em> and <em>Staphylococcus aureus</em>. Due to these enhanced properties, cold plasma-treated egg white protein is highly valued as a component in a wide range of food products, such as baked goods, dairy substitutes, meat products, and beverages. However, it is important to note that its use in large-scale production has not been extensively implemented yet.

Candidate yeast strains and processes for producing biomass from these substrates are reviewed in relation to production efficiency and product functionality. The opportunity to lower production costs and control yeast cell properties using continuous cultivation is highlighted.

In particular, this review provides insights into how the variety and adaptability of yeast can make it possible to adjust attributes such as protein and cell wall composition through strain selection and controlled production. Major gaps are identified as targets for future research, in particular understanding the functional properties of non-<em>Saccharomyces</em> yeast biomass that could be produced from lignocellulosic sugars, lactose and precision fermentation.

The blended mode was implemented to target the simultaneous extraction of essential oil and non-volatile principles (phenolics) from the same biomass through a two-stage process. The first stage dealt with the extraction of essential oil using an optimized MHG protocol comprising of a blend of high- (510 W) and medium-power (340 W) microwave surges of 5 min each, followed by the completion of the experiment with low power microwave (170 W). The yield of essential oil obtained from the optimized MHG protocol (50 min) was found to be 5% w/w. On the other hand, MHG with single-power microwaving at 170 W (60 min), 340 W (40 min) and 510 W (25 min) produced yields of 1.9%, 2.9% and 1.0% w/w, respectively. Hydrodistillation (240 min) could achieve a yield of 1.9% w/w only. As per gas chromatography results, the % area of eugenol content was found to be 16.64%, slightly higher than the 15.45% obtained from hydrodistillation. The second stage was about retention capabilities of the biomass with reference to the non-volatile components.
