A NIR method was developed for the on-line monitoring of alkali-free cloth/phenolic resin prepreg during its manufacturing process. First, the sizing content of the alkali-free cloth was analyzed, and then the resin, soluble resin and volatiles content of the prepreg was analyzed simultaneously using the FT-NIR spectrometer. Partial least square (PLS) regression was used to develop the calibrat...

The valorization of tree bark through chemical treatment into valuable products, such as acid, leads to the formation process residues with a high solids content. Since they are natural origin and able be suspended in water research was carried out on recycling suberic acid (SAR) bi-functional component binder mixtures production plywood. 5%–20% (5%–30% for curing time) mass content SAR has bee...

The objective of the study was to compare the antioxidant activity of two distinct hydrolysates and their peptide fractions prepared by ultrafiltration (UF) using membranes with molecular weight cut-off of 5 and 1 kDa. The hydrolysates were a delipidated egg yolk protein concentrate (EYP) intensively hydrolyzed with a combination of two bacterial proteases, and a phosphoproteins (PPP) extract p...

We prepared a novel type of milk calcium from milk whey, and evaluated its calcium bioavailability as compared with conventional industrial milk calcium obtained from milk whey, which has been reported to be an excellent calcium source. An X-ray diffraction analysis showed that the chemical form of conventional industrial milk calcium from milk whey through the neutralization and precipitation ...

Two experiments were performed to determine the physical and mechanical characteristics of panels consisting of a veneer face and a particleboard core composed of mixed wood particles/powdered-recycled polyethylene (PE) bag waste (MWP) using urea-formaldehyde (UF) resin as a binder. The addition of 25 percent powdered-recycled PE bag waste to the MWP panels did not adversely affect nonaged bond...

In this study, the urea-formaldehyde (UF)-tung oil solution of phenolic amide (PA) microcapsules to realize anti-fouling and anti-corrosion integration was synthesized by in situ polymerization method. The compounds structures were optimized investigating six kinds different emulsifiers. results showed that high-core-content narrow-particle-size-distribution could be with sodium dodecyl benzene...

introduction: scientific evidence has demonstrated that consumption of high-fat foods has direct connection with increasing incidences of various diseases such as obesity, diabetes, hardening of the artery walls and blood pressure. thus, demand for low-fat foods has increasingly been promoted by health-conscious consumers. however, development of low-fat foods is challenging as fat makes a majo...

The effectiveness of microfiltration (MF) and ultrafiltration (UF) for nutrient recovery from a thin stillage stream was determined. When a stainless steel MF membrane (0.1microm pore size) was used, the content of solids increased from 7.0% to 22.8% with a mean permeate flux rate of 45L/m(2)/h (LMH), fat increased and ash content decreased. UF experiments were conducted in batch mode under con...

Dried milk protein concentrate is produced from skim milk using a combination of processes such as ultrafiltration (UF), evaporation or nanofiltration, and spray drying. It is well established that dried milk protein concentrate (MPC) that contains 80% (MPC80) and greater protein content (relative to dry matter) can lose solubility during storage as a result of protein-protein interactions and ...

the aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable h+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. drug resin complexes (drc) were prepared and evaluated for the percentage of moisture gain when placed in a humidity chamber at 40e2 °...
