The aim of this investigation was to improve the barrier and mechanical properties of gluten films and further explore their application in the packaging of seasonings. The effects of flaxseed gum (FG), oligomeric procyanidins (OPCs), and lauric acid (LA) on the water vapor permeability (WVP), mechanical properties, and peroxide value (POV) were determined. FG and OPCs improved the WVP properties of the gluten films, whereas LA significantly improved the oxygen-barrier properties. The FG/OPCs/LA/GP composite film was then optimized, and the morphological, microstructural, and thermal properties of the composite gluten film were investigated by scanning electron microscopy, atomic force microscopy, surface hydrophobicity analysis; Fourier transform infrared spectroscopy; thermal gravimetric analysis, respectively...

#5
Xiaoli Luan, Minjun Jin, Fei Liu
The fault detection problem of the oil desalting process is investigated in this paper. Different from the traditional fault detection approaches based on measurable process variables, near-infrared (NIR) spectroscopy is applied to acquire the process fault information from the molecular vibrational signal. With the molecular spectra data, principal component analysis was explored to calculate the Hotelling T2 and squared prediction error, which act as fault indicators. Compared with the traditional fault detection approach based on measurable process variables, NIR spectra-based fault detection illustrates more sensitivity to early failure because of the fact that the changes in the molecular level can be identified earlier than the physical appearances on the process...

Epidermolysis bullosa is a rare blistering skin disorder that is challenging to manage because skin fragility and repeated wound healing cause itching, pain, limited mobility, and recurrent infections. Cannabidiol, an active cannabinoid found in cannabis, is postulated to have antiinflammatory and analgesic effects. We report 3 cases of self-initiated topical cannabidiol use in patients with epidermolysis bullosa in an observational study. One patient was weaned completely off oral opioid analgesics. All 3 reported faster wound healing, less blistering, and amelioration of pain with cannabidiol use...

Synthesized organobentonite (SOB), montmorillonite (MMT), and commercial organobentonite (COB) were used as adsorbents for paraffin oil, a model pollutant in land-based oil spills and oil pipeline rupture. The characterization of clays was carried out with scanning electron microscopy (SEM), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). After adsorption, oil was separated from adsorbents with a carbon dioxide responsive solvent N,N-dimethylcyclohexylamine (DMCHA), and DMCHA was subsequently separated from paraffin oil upon CO2 bubbling instead of distillation with high energy cost...

The seed oil of Jatropha curcas is considered a potential bioenergy source that could replace fossil fuels. However, the seed yield of Jatropha is low and has yet to be improved. We previously reported that exogenous cytokinin treatment increased the seed yield of Jatropha . Cytokinin levels are directly regulated by isopentenyl transferase (IPT), cytochrome P450 monooxygenase, family 735, subfamily A (CYP735A), and cytokinin oxidase/dehydrogenase (CKX). In this study, we cloned six IPT genes, one JcCYP735A gene, and seven JcCKX genes...

Droplet microfluidics enables massively-parallel analysis of single cells, biomolecules, and chemicals, making it valuable for high-throughput screens. However, many hydrophobic analytes are soluble in carrier oils, preventing their quantitative analysis with the method. We apply Printed Droplet Microfluidics to construct defined reactions with chemicals and cells incubated under air on an open array. The method interfaces with most bioanalytical tools and retains hydrophobic compounds in compartmentalized reactors, allowing their quantitation...

In this study, a one-step method for producing phytosteryl phenolates, namely phytosteryl cinnamate and ferulate, has been successfully developed and their chemical structures were confirmed by FT-IR, MS and NMR. The highest yield of phytosteryl ferulate (85.7%) was obtained at 100 °C for 2 h after optimization. A Lewis acid catalyst scandium triflate was selected as the catalyst, and it turned out that it could be reused for at least five times without significant loss of activity. Meanwhile, it has been demonstrated that the solubility of phytosteryl phenolates in soybean oil was much higher than in both phenolic acid and phytosterol, which was conducive to expand their applications in oil-based food...

Fish-oil (FO) was encapsulated with hydroxypropylcelullose (HPC) by conventional spray-drying with water (FO-water) and solvent spray-drying with ethanol (FO-EtOH), methanol (FO-MeOH) and acetone (FO-Acet) in order to study the effect of the solvent on the encapsulation efficiency (EE), microparticle properties and stability of FO during storage at 40 °C. Results showed that FO-Acet presented the highest EE of FO (92.0%), followed by FO-EtOH (80.4%), FO-MeOH (75.0%) and FO-water (71.1%). A decrease of the dielectric constant increased the EE of FO, promoting triglyceride-polymer interactions instead of oil-in-water emulsion retention...
