Cocoon silks are composed of two silk proteins: sericin and fibroin. Fibroin is a semi crystalline polymer of natural fibrous protein mainly consisting of highly β-sheet crystals and noncrystalline part (micro voids and amorphous structures). Sericin is amorphous acting as an adhesive binder to maintain the fine filaments of fibroin core and the overall structural integrity of cocoon [1]. Silk ...

Effect of ultrasound assisted extraction’s condition on degumming process and investigation quality parameters soybean oil

This study compared the profiles of fatty acids, phytosterols, and polyamine conjugates in conventional commercial corn oil extracted from corn germ and in two ‘‘new-generation’’ corn oils: hexane-extracted corn fiber oil and ethanol-extracted corn kernel oil. The fatty acid compositions of all three corn oils were very similar and were unaffected by degumming, refining, bleaching, and deodoriz...

Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating preliminary process and esterification. is degummed using phosphate acid bleached with carbon active. Additionally, this study KOH-impregnated zeolite to reduce FFA. The purpose determine effect adding impregnated on was he...

BACKGROUND Enzymatic biodiesel is becoming an increasingly popular topic in bioenergy literature because of its potential to overcome the problems posed by chemical processes. However, the high cost of the enzymatic process still remains the main drawback for its industrial application, mostly because of the high price of refined oils. Unfortunately, low cost substrates, such as crude soybean o...

<p>Kesambi seed oil (<em>Schleichera oleosa</em>) is one of the resources that can be utilized as an alternative to substitute palm in cooking production due its lower moisture content, peroxide value, and saponification number. However, high level free fatty acid (FFA) cyanide (HCN) contents kesambi requires further purification prior commercialization. In this study, process...
