Identification and Quantification of 5-Hydroxymethyl Furfural in Food Products
5-Hydroxymethylfurfural (5-HMF) is known as an indicator of quality deterioration in a wide range of foods. The current study covered 70 samples taken from domestically produced foods and drinks available on the Iranian markets (including honey, jam, fruit cakes tomato paste, ketchup, syrup, fruit juice, canned fruit, UHT milk, instant coffee and jelly powder). HMF levels were determined using ...
متن کاملIdentification and characterization of the furfural and 5-(hydroxymethyl)furfural degradation pathways of Cupriavidus basilensis HMF14.
The toxic fermentation inhibitors in lignocellulosic hydrolysates pose significant problems for the production of second-generation biofuels and biochemicals. Among these inhibitors, 5-(hydroxymethyl)furfural (HMF) and furfural are specifically notorious. In this study, we describe the complete molecular identification and characterization of the pathway by which Cupriavidus basilensis HMF14 me...
متن کاملConversion and assimilation of furfural and 5-(hydroxymethyl)furfural by Pseudomonas putida KT2440
The sugar dehydration products, furfural and 5-(hydroxymethyl)furfural (HMF), are commonly formed during high-temperature processing of lignocellulose, most often in thermochemical pretreatment, liquefaction, or pyrolysis. Typically, these two aldehydes are considered major inhibitors in microbial conversion processes. Many microbes can convert these compounds to their less toxic, dead-end alco...
متن کاملPhotoassist-phosphorylated TiO2 as a catalyst for direct formation of 5-(hydroxymethyl)furfural from glucose.
Photo-assisted phosphorylation of an anatase TiO2 catalyst was examined to improve its catalytic performance for the direct production of 5-(hydroxymethyl)furfural (HMF), a versatile chemical platform, from glucose. In phosphorylation based on simple esterification between phosphoric acid and surface OH groups on anatase TiO2 with water-tolerant Lewis acid sites, the density of phosphates immob...
متن کاملConversion of fructose into 5-(hydroxymethyl)furfural in sulfolane.
Population growth has created an expanding gap between the supply and demand of both energy and chemicals. Nonrenewable fossil sources, such as coal, natural gas, and petroleum, are the source of nearly 86% of the world’s energy and 96% of its organic chemicals. Diminishing reserves of these sources, rising atmospheric CO2 levels, and socioeconomic concerns require a reduction of our dependence...
