Abstract Due to their antioxidant activity, anthocyanins are of increasing interest for nutritionists, food scientists and plant breeders. Anthocyanins in wheat grains expressed either the pericarp or aleurone layer. Previous studies revealed that different present varieties carrying genes purple blue trait. Progeny from crosses between red‐, purple‐ blue‐grained were selected over several cycles grain colour by visual scoring. Bulked F 5 evaluated total anthocyanin content UV ‐ VIS...
Development of polyurethane foam (PUF) containing bio-based components is a complex process that requires extensive studies. This work reports on the production rigid PUFs from polyol obtained via liquefaction oil palm empty fruit bunch (EFB) biomass with different isocyanate (NCO) indexes. The effect NCO index physical, chemical and compressive properties liquefied EFB-based PUF (EFBPUF) was evaluated. EFBPUFs showed unique set at each index. Foaming had affected apparent density cellular...
The liquid hot water (LHW) pretreatment on cotton linter (CL) was carried out using an autoclave heated in a oil bath.The LHW pretreated CL (LCL) dissolved NaOH/urea and LiOH/urea aqueous solutions subsequently used to produce cellulose membrane.The effects of pretreatment, amount cellulose, type alkaline solvent properties solution membrane were studied.The formation II crystallinity index (CrI) the membranes confirmed by X-ray diffraction (XRD).The morphology observed field emission...
Fiber processing is an important factor that affects the physical and mechanical properties of long kenaf fiber. The physical-mechanical properties, such as color, tensile strength, moisture regain (MR), are main characteristics influence performance on final products from objective this research was to evaluate fiber at week planting, with different methods were planted in a selected location Malaysia. Kenaf separated by water retting method, where combination based available facilities...
In this study, magnetic cellulose membranes (MCM) have been prepared by using cotton linter as source and NaOH/urea solvent at different magnetite content.Cellulose was dissolved in pre-cooled -13°C to form solution.The solution then mix with (Fe 3 O 4 ) nanoparticles synthesized via co-precipitation method of Fe 2+ 3+ the presence sodium hydroxide (NaOH) MCM. The MCMs formed percentage i.e., 10, 20 30%.Analysis from vibrating sample magnetometer (VSM) shows that saturation magnetization MCM...
Regenerated cellulose membranes (RC) from kenaf core pulp have been produced using the pre cool method and coagulated sulfuric acid (H 2 SO 4 ) solution.RC prepared was dissolved in NaOH/urea solvent subsequently with H solution at concentration 5-12 wt.% for 1-10 min.The effects of coagulating time on structure, pore size, mechanical properties transparency RC were studied X-ray diffraction (XRD), variable pressure scanning electron microscopy (VPSEM), tensile tester spectrometer ultra...
The effectiveness in the dehydration of sugars into 5-Hydroxymethylfurfural is related to catalyst existence. A comprehensive synthesis from fructose, glucose and sucrose (3.73 mmol) with without addition zeolite was performed this study. reactions were carried out water-methanol solvent system for 3 hours reaction time at 180°C temperature. catalytic results HPLC showed that increases yield 51.72 %, 34.01% 50.10% respectively. study suggests zeolites promote isomerization fructose occur...
Alkaline pretreatment using ammonium hydroxide, NH4OH serves as one of a process to remove lignin from lignocellulosic biomass such oil palm trunk fiber. In this study, the effect on removal was investigated. The fiber dissolved in with different concentrations (6, 8 and 10 %), duration (3, 5 7 h) temperatures (60, 80 100 °C). samples were analyzed by UV-Vis estimate concentration extracted lignin. result indicates that optimum conditions gain maximum 8% NH4OH, °C h 64 mgL-1 while lowest at...
Calcium rich solid base catalyst was synthesized from local waste carbide lime and its catalytic performance evaluated via biodiesel production. Carbide used to produce CLW-I CLW-II using different preparation methods. Characterization including strength analysis, scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) diffraction (XRD) were investigated. Catalytic examined by deploying the catalysts for transesterification reaction of palm oil. Fourier Transform...
In this current study, the soda lignins from empty fruit bunch (EFB) and kenaf core were recovered by two step precipitation method. The objective of research is to study purity lignin washing with acidified water. purified undergone characterization FT-IR, Uv-Vis XRD. FT-IR analysis shows that has Guaiacyl(G) Syringyl(S) unit meanwhile EFB Hydroxyphenyl(H), lignin. As for XRD analysis, non-purified existence impurities which salt (NaCl). UV higher absorbance lead
Bio-novolac fibre made from phenol-formaldehyde derived oil palm empty fruit bunch (EFB) was produced using electrospinning method.The bio-novolac prepared via liquefaction and resinification at two different molar ratios of formaldehyde to liquefied EFB (LEFB) (F:LEFB = 0.5:1 0.8:1).Electrospinning applied the (BPF) in order form smooth thin as-spun fibre.The BPF electrospun 15 kV cm distance between needle collector a flow rate 0.5 mL/h.At lower molecular weight resin, beads formation...
