Insects have a great potential to be used as feedstocks for biodiesel production due their intrinsic high lipid contents. In particular, from black soldier fly larvae (BSFL) is promising because of its advantages in engineering aspects such rapid proliferation, more storage long-development time larva stage, self-separation organic waste. this study, was synthesized through (trans)esterificatio...

Coconut is widely used as a food source in producing countries, and during consumption, the waste that generated needs to be reduced through by-products processing ensure environmental sustainability. This study aimed assess functionality of (endo- mesocarp) coconuts at early mature stages. The aqueous ethanolic (50 100% ethanol water) extracts coconut were evaluated for DPPH radical scavenging...

This work examines pressurized accelerated oxidation by a RapidOxy tester as an alternative method for determination of biodiesel stability. Sunflower oil-based was synthesized and treated with antioxidants: tert-butylhydroquinone (TBHQ) - synthetic antioxidant known its powerful protective effect, mixture bio-based compounds extracted from vinery waste, VWEeth. The potency TBHQ evaluated at va...

A simple and efficient method was established for the determination of synthetic antioxidants in beverages by using dispersive liquid-liquid microextraction combined with high-performance liquid chromatography with ultraviolet detection. Butylated hydroxy toluene, butylated hydroxy anisole, and tert-butylhydroquinone were the antioxidants evaluated. Experimental parameters including extraction ...

A total of 75 compounds, including antioxidants, preservatives, gallic acid and p-hydroxybenzoic acid esters, hydroquinones, hydroxyquinolines, phenol derivatives, and related compounds, were screened for their antibotulinal activity in prereduced Thiotone-yeast extract-glucose broth. The most effective inhibitors of Clostridium botulinum growth and toxin production were long-chain esters of p-...

AOCS Official Method Ce 6-86 "Antioxidants, Liquid Chromatographic Method" was originally developed to confirm the correct antioxidant was added at the specified concentration to refined oils. Today, this method is increasingly utilized to validate that antioxidants are absent from oil products. False positive results can have a significant impact on the ability to sell products in specific mar...
