Capsaicin o/w nanoemulsions with enhanced skin permeation were successfully prepared by controlling the ratios of surfactant mixtures, oleoresin capsicum as oil phase, and aqueous phase. Oleoresin contains 22.67 mg/g capsaicin, which is an active oil-soluble ingredient. Nonionic surfactants, Tween 80 Span 80, used to optimize weight ratio mixtures (85.98:14.02) calculating hydrophile–lipophile balance (HLB) value. The optimal processing conditions for stable investigated using a ternary...

Improving the antibacterial activity of biodegradable materials is crucial for combatting widespread drug-resistant bacteria and plastic pollutants. In this work, we studied polyaniline (PANI)-functionalized zinc oxide nanoparticles (ZnO NPs) to improve surface charges. A PANI-functionalized ZnO NP was prepared using a simple impregnation technique. The PANI functionalization successfully increased positive charge NPs. addition, improved mechanical properties thermal stability. Besides those...

This study investigates the potential complications in applying nanoclay-based waterborne coating to packaging films for food with high moisture content. Multilayer were prepared by dry laminating commercially available polyvinyl alcohol (PVA)/vermiculite nanocomposite and linear low-density polyethylene film, changes oxygen barrier properties investigated according different relative humidity using 3 types of simulants. When was above 60%, permeability increased sharply, but this...

Abstract Curcumin solid dispersions were prepared using hydroxypropyl methylcellulose (HPMC) to enhance water solubility of curcumin. The particle size curcumin was in range from 371 528 nm and particles shaped as spherical with wrinkles. encapsulation efficiency over 93% for all samples, significantly improved 238 µg/mL when the ratio HPMC 20:80. results X‐ray diffraction, differential scanning calorimeter, Fourier transform infrared spectroscopy showed that crystalline form changed...

Beeswax and a plasticizer (ATBC) were added to polylactic acid (PLA) films in order enhance the water vapor barrier properties of films. improved properties; permeability composite containing 1% beeswax was 58% lower than that neat PLA. Fourier transform infrared spectroscopy X-ray diffraction analysis revealed incorporation ATBC had so little effect on PLA structure. In addition, structure did not vary substantially with additions. The surfaces composites examined by using field emission...

Acrylic acid monomer in a viscous supporting nylon solution was polymerized and fabricated simultaneously via an electrospinning process. This novel polymerization method defines the fiber morphology as network of interconnected mats. consists smaller poly(acrylic acid) (PAA) fibers, approximately 19 nm diameter, larger 6 75 diameter. These two different fibers are separated by extraction PAA from fibrous mat water differentiation field-emission scanning electron microscopy (FESEM) images...

The objectives were to investigate the effects of formulation variables on release drug and optimize chitosan microparticles loaded with for controlled using response surface methodology. Chitosan prepared by dropping a solution into sodium tripolyphosphate (TPP) through ionic cross-linking. behaviour felodipine as model was affected preparation variables. A central composite design used evaluate effect variables, concentration (X1), pH TPP (X2) cross-linking time (X3) cumulative per cent...

ABSTRACT The objective of this study was to establish the ability microencapsulation entrap allyl isothiocyanate (AITC) and extend its shelf life. Microcapsules were prepared by spray drying after emulsification, using different mass ratios gum arabic (GA) AITC (3:1, 4:1, 5:1 6:1) with tween20 or span80. efficiency release characteristics GA/AITC microcapsules investigated. Retention during increased as ratio GA increased. Avarami's parameter n values all powders indicated that controlled...

Abstract The plasma source ion implantation technique was applied to modify the surface of ethylene‐vinyl alcohol (EVOH) film using various working gases. effects treated films were observed on adhesion efficiency and physical properties. hydrophobic properties EVOH greatly enhanced after tetrafluoromethane‐plasma (PSII) treatment. On other hand, higher hydrophilic increased oxygen‐PSII results X‐ray photoelectron spectroscopy showed that improved or closely related formation...

Melt blowing(MB) is a process for producing fibrous webs or articles directly from polymers resins using high-velocity air another appropriate force to attenuate the filaments. This one of newer and least developed nonwoven processes. unique because it used almost exclusively produce microfibers rather than fibers size normal textile fibers. MB generally have diameters in range 2 4 ㎛, although they may be as small 0.1 ㎛ large 10 15 ㎛. The material acoustic property noise absorption...

Rice noodle is one of the most popular foods consumed in Asia. However, rice flour lacks gluten that forms a cohesive dough structure wheat-based noodles and for gluten-free, rice-based formulations an alternative to needed. Therefore, effects addition hydroxypropyl methylcellulose (HPMC) as replacement temperature water used preparation were investigated. contained high-viscosity HPMC (6%) had smallest breakdown largest setback viscosity, also better texture sensory properties. The use at...

Bioavailability and bone loss inhibitory effects of vitamin D

Abstract Acetylated chitosan sponges (chitin sponges) were prepared according to acetylation time (25, 50, 75, and 100 h). As the increased, degree of a 75‐h produced highest (DA). The surface morphologies samples examined by scanning electron microscopy. Sponge shown water uptake ability test have higher absorption abilities. An in vitro biodegradation showed that with DA more susceptible lysozyme hydrolysis. further an fibroblast proliferation cell viability on increasing DA, 75 h...
