The aim of the current work was to produce sodium alginate (SA) maltodextrins (MD) based functional films incorporated with phenolic extract of Azolla pinnata leaves fern (AF) by solution molding technique. AF with different concentrations (0.8, 1.2 and 1.6% w/w) were integrated inside SA.MD films. The resulted films were characterized to investigate the surface structure by scanning electron microscope (SEM), thermal disposal by (DSC), crystallization by X-ray diffraction (XRD), potential interaction by (FT-IR) and some mechanical properties. The SEM micrographs indicated that the higher concentration (1.6%) of AF extract caused development of wrinkles on the surface of films. And as a result, there were a significant decrease of elongation at break (EB) and tensile strength properties of films to 55.01 and 58.42%, respectively. By continues addition of AF extract to SA.MD films, the film thickness increased from 0.124 to 0.181 mm, the scavenging and antimicrobial properties were enhanced by the attendance of ferulic acid, rutin, thiamine, tamarixetin, astragalin, quercetin, chlorogenic acid and epicatechin inside extracts. Furthermore, the films solubility, swelling degree and water vapor permeability were decreased to 13.08%, 26.41% and 1.662?×?10??10 g H2O/m s p.a. The resulted films could be utilized as composite packaging material for different food applications.

The compatibility between luxury and sustainable development has been increasingly examined in recent literature, but a number of ethical issues remain unexplored. One such concern is animal welfare, a recurrent question in the luxury goods sector. This is one of the first research articles to shed light on this subject, utilising two studies, one qualitative and the other quantitative with conjoint analysis, conducted among 12 and 253 French consumers, respectively. The results reveal that consumers are sensitive to the challenge of animal welfare in luxury, but fall into two different groups. Some have a preference for animal‐based raw materials sourced from livestock farms that respect animal welfare, whilst others are more favourable to the use of synthetic raw materials. In particular, the results show that the use of synthetic raw materials is accepted by some consumers but can lead to a reduction in the perceived value of luxury products.  相似文献

The present study investigates the feasibility of using two types of municipality solid wastes incineration ashes, namely, fly ash and bottom ash in the production of sustainable alkali-activated binder. The ashes are collected from the incineration plant and characterized to determine their particle size distribution, specific gravity, chemical composition, and heavy metals content. The ashes are then used as either fly ash or sand replacement with five replacement ratios 0%, 5%, 10%, 15%, and 20% to produce the binder. The produced binder are characterized in terms of strength, workability, density, water absorption, thermal conductivity and stability, chemical composition, and heavy metals content. The results reflect the ability of producing sustainable alkali-activated binder with small dosage of MSWI ashes as either fly ash or sand replacement without negatively affecting its strength, workability, density, and water absorption. The ashes enhance the thermal insulation capability of the binder.
