“…In the LDV measurement, the velocity of a moving NDS in an applied electric field is determined using a laser, and is proportional to electrophoretic mobility. The electrophoretic mobility value can be used to calculate the zeta-potential value using the Smoluchowski equation [66].…”

Various bioactive compounds (BCs) often possess poor stability and bioavailability, which makes it difficult for them to exert their potential health benefits. These limitations can be countered by the use of nano-delivery systems (NDSs), such as nanoparticles and nanoemulsions. NDSs can protect BCs against harsh environments during food processing and digestion, and thereby, could enhance the bioavailability of BCs. Although various NDSs have been successfully produced with both synthetic and natural materials, it is necessary to fulfill safety criteria in the delivery materials for food applications. Food-grade materials for the production of NDSs, such as milk proteins and carbohydrates, have received much attention due to their low toxicity, biodegradability, and biocompatibility. Among these, whey proteins—from whey, a byproduct of cheese manufacturing—have been considered as excellent delivery material because of their high nutritional value and various functional properties, such as binding capability to various compounds, gelation, emulsifying properties, and barrier effects. Since the functional and physicochemical properties of whey protein-based NDSs, including size and surface charge, can be key factors affecting the applications of NDSs in food, the objectives of this review are to discuss how manufacturing variables can modulate the functional and physicochemical properties of NDSs and bioavailability of encapsulated BCs to produce efficient NDSs for various BCs.

Initially waste feather protein was used to prepare a reactive cationic crosslinking modified agent, WLS, as a starting material which was used to prepare a quaternary ammonium type cationic environment-friendly fixing agent (named WLSPR) for dyeing cotton fabric with reactive dyes after solid colour processing. In this paper, the degree of staining on white cloth from colored cloth after a soaping process was assessed (by determination of the K/S value) as well as the washing fastness etc. as the evaluation indices. The optimum synthetic conditions of fixing agent WLSPR were determined, and the structure and properties of the additives characterised. The results show that the maximum absorption wavelength of the cationic protein fixing agent WLSPR is 195nm. Synthesis of the environment-friendly fixing agent WLSPR using optimum conditions can reduce white staining during soap washing , effectively improving the cotton fabric in terms of colour fastness to washing and rubbing fastness. Based on infrared spectral characterisation, it was confirmed that the protein-based cationic auxiliary additives were synthesised.

A type of cationic decolourising agent was prepared and applied to printing and dyeing wastewater treatment. The effects of the concentration of the decolourising agent, the pH value and stirring speed on decolourisation efficiency were studied. The results show that the optimum decolourisation process of the decolourising agent is determined as follows: at room temperature, a dosage of the decolourising agent of 7 mg/l, pH =7.0, and a stirring speed of 150 rpm. The decolourising agent applied to decolourise a direct dye, strong acid dye, weak acid dye and reactive dye in simulated wastewater showed high decolourisation efficiency in all cases. The range of decolourisation efficiency from the highest to lowest is as follows: direct dye, weak acid dye, strong acid dye, and reactive dye.
