Cachaça is the popular name of sugarcane liquor obtained from fermented sugarcane mash broth. This is one of the most popular alcoholic beverages in Brazil and is gaining ground in the global market. One of the quality ...

The dehydration of fructose and glucose to 5-hydroxymethylfurfural was studied using LaOCl/Nb2O5 in hot compressed water conditions. The catalysts were prepared by impregnation of LaCl3 on Nb2O5 with different loadings. ...

In this work, Preyssler-type heteropolyacids and their silica-included counterparts were employed in the etherification reaction of HMF and n-BuOH. Materials were synthesized with a Preyssler acid load of 12.5% w/w using ...

A glassy carbon electrode chemically modified with nickel nanoparticles coupled with reversed-phase chromatography with pulsed amperometric detection was used for the quantitative analysis of furanic aldehydes in a real ...

Thermal degradation and generation of objectionable compounds such as hydroxymethylfurfural have been observed in hot pressurised water extraction of polyphenols. Addition of small amounts of ethanol can reduce process ...

The objectives of this research were to determine physico-chemical characteristics of 1,758 Apis mellifera L. honey samples produced by in the productive pole of Picos, state of Piauí, to understand, based on these ...
