Multiple layers of whey protein and sodium alginate were assembled onto gelled alginate microparticles using electrostatic interaction. An experimental design was employed to evaluate the effect of the concentration of both hydrocolloids on the amount of protein that was adsorbed. In the first layer, a higher protein adsorption 32.5% w/w was obtained at pH 3.75. In the multilayered particle, the protein adsorbed reached 64.9% w/w. An analysis of protein solubilization verified that 22% w/w was solubilized at an acidic pH (pH 2...

Tattooing is a skin trauma and involves a special vulnus punctatum (with inserted tattoo ink, a vulnus venenatum), which should heal with no infection and no local complication. Local treatment in the healing phase ideally builds on the 'moist wound' principle using plastic film, hydrocolloids, silver dressing, and compression. Bacterial infections during healing are treated with oral antibiotics, and a list of first-line antibiotics is proposed. Notice is given to severe infections with affected general condition, and it is emphasized that intravenous antibiotic treatment must be instituted as early as possible to prevent septic shock and death...

Conventional dressings are cost-effective and highly absorbent, but not effectual enough to promote hemostasis, adherence and in holding a moist wound bed. Thanks to the developments in the field of nanotechnology and bioengineering, one of the promising current trends is to move progress of innovative wound dressings, merging the application of traditional healing agents and modern products/practices, such as hydrocolloids, hydrogels, films and nanofibers. The electrospun nanofibers webs can provide the essential parameters require for wound dressing to heal wounds including absorptivity, oxygen permeability, and non-adherence to the healing tissue, barrier to bacteria, bioactivity and occlusivity...

The use of gluten-free products is increasing since a growing number of people are suffering from celiac disease and thereby need gluten-free diet. Gluten is responsible for the visco-elastic characteristics of wheat-based products; therefore, its lack makes the gluten-free products not similar to wheat-based product, with scarce textural properties. This reason constitutes the major industrial limitation. Thus, obtaining good-quality gluten-free products represents a technological challenge. This review reports the main strategies adopted to produce high quality gluten-free pasta and bread...

Clay aerogels are foam-like materials with potential to combine high mechanical performance with fire retardancy. However, the compression strength of these aerogels is much lower than theoretically predicted values. High-strength aerogels with more than 95% porosity were prepared from a ternary material system based on poly(vinyl alcohol), montmorillonite clay platelets, and cellulose nanofibrils. A hydrocolloidal suspension of the three components was subjected to freeze-drying so that a low-density aerogel foam was formed...
