In this study, ultrasound- and enzyme-assisted extractions of albumin (water-soluble protein group) from defatted pumpkin (Cucurbita pepo) seed powder were compared. Both advanced extraction techniques strongly increased the albumin yield in comparison with conventional extraction. The extraction rate was two times faster in the ultrasonic extraction than in the enzymatic extraction. However, t...

The composition and physical properties of raw milk from a commercial herd were studied 8 over a one year period in order to understand how best to utilise milk for processing 9 throughout the year. Protein and fat levels demonstrated seasonal trends, while minerals and 10 many physical properties displayed considerable variations, which were apparently unrelated 11 to season. However, rennet c...

Abstract Food waste continues to increase as the population increases. The buildup of food can cause environmental pollution and imbalance in system. With potential for various problems that be caused by animal husbandry activities, use Black Soldier Fly (BSF) larvae is expected helping organic decomposition, well becoming an alternative protein source. Therefore, this study aims amino acid pro...

water stability of warm mix asphalt mixture based on foamed is the key evaluation index affecting its road performance. The moisture content in production process unfavorable to mixture. In order improve stability, through immersion Marshall test and freeze-thaw splitting test, taking foaming effect, temperature, consumption polymer fiber as influencing factors, control variable method used stu...

ABSTRACT Specialty natural rubber (SpNR) latex, namely, deproteinized (DPNR) latex and epoxidized (ENR) has been produced to meet specific product's requirements. However, SpNR is normally used in the form of block manufacture dry products such as tires automotive parts. The applications into foam will be diversified. Findings indicate that foamability lower compared normal (LATZ) but shows lon...

Solar-driven interfacial evaporation is regarded as one of the most promising technologies to address critical issue global water scarcity . However, a great deal energy lost via conduction during process. Herein, self-floating Janus evaporator containing micron-sized isolated bubbles that can enhance heat localization designed. The synthesized by gas foaming polyacrylonitrile (PAN) nanofibers ...

Bacterial cellulose (BC) is a biodegradable, non-toxic, natural substance that can be obtained by culturing bacteria. It approached in various ways from physical, chemical, and biological points. BC nanoparticles have been applied as lubricating additives to improve the load capacity, anti-wear, friction. The microcellular foaming process was created using technology based on saturation of poly...

In this study, we attempted to enrich cyclo-His-Pro (CHP) using enzymatic hydrolysis of yeast and to evaluate the functionality of yeast hydrolysate (YH)-enriched CHP. Flavourzyme offered a better performance in enhancing CHP content than other proteases. The CHP enrichment conditions were optimized as follows: addition of 1% Flavourzyme, 48-h incubation at 60°C, and pH 6.0. The CHP content sig...

In this paper, components of an industrial wastewater that cause operational problems during biological treatment were oxidized by UV light and hydrogen peroxide (UV/H202). Preoxidation of wastewater was shown to remove polyvinylpyrrolidone (PVP) and ethoxylate surfactant and increase overall biodegradability. Several UV intensities and hydrogen peroxide concentrations were tested to find optim...

The objective of this research was to determine the effect of sugar or fatty acid in sugar ester compounds on the surface-active properties and antimicrobial activities of these compounds. Disaccharides of medium-chain fatty acid monoesters were synthesized through transesterifications by immobilized lipase (Lipozyme TLIM) to yield nine monoesters for subsequent study. Their antimicrobial activ...
