Comprehensive Characterization of Raw and Processed Quinoa from Conventional and Organic Farming by Label-Free Shotgun Proteomics.

J Agric Food Chem

January 2025

Department of Chemical Engineering and Analytical Chemistry, Institute for Research on Nutrition and Food Safety (INSA·UB), University of Barcelona, 08028 Barcelona, Spain.

Quinoa is widely recognized for its exceptional nutritional properties, particularly its complete protein content. This study, for the first time, investigates the effects of processing methods (boiling and extrusion) and farming conditions (conventional and organic) on the proteomic profile. Following a label-free shotgun proteomics approach, a total of 1796 proteins were identified and quantified across all quinoa samples.

Acetaminophen (APAP), one of the most frequently used antipyretic and analgesic medications, has recently grown into a persistent organic contaminant of emerging concern due to its over-the-counter and widespread use. The excessive accumulation of APAP and its derivatives in various environmental matrices is threatening human health and the ecosystem. The complexity of APAP and its intermediates augments the need for adequate innovative and sustainable strategies for the remediation of contaminated environments.

Heavy metal contamination in water bodies has raised global concerns due to its significant threats to both public health and ecosystem. Copper (Cu), one of the most widely used metals, is also an essential trace element in physiological systems. Excessive intake of Cu from water can cause toxicity, potentially resulting in serious health risks.

Article Synopsis
  • Glucose sensing is essential for managing diabetes, and this study explores NbCT-selenium nanoparticles for effective nonenzymatic glucose detection.
  • The composite material was characterized using techniques like scanning and transmission electron microscopy, and it was tested on a gold disc electrode in an alkaline solution.
  • The sensor operates at a low overpotential of 0.16 V, demonstrating a detection range of 2 to 30 mM, with a notable sensitivity of 4.15 µA mM cm and a detection limit of 1.1 mM.

Excess biological sludge processing and disposal have a significant impact on the energy balance and economics of wastewater treatment operations, and on receiving environments. Anaerobic digestion is probably the most widespread in-plant sludge processing method globally, since it stabilizes and converts biosolids organic matter into biogas, allowing partial recovery of their embedded chemical energy. A considerable number of studies concerning applicable techniques to improve biogas production, both in quantity and quality, include pre-treatment strategies to promote biosolids disintegration aimed at the release and solubilisation of intracellular energy compounds, inorganic/biological amendments aimed at improving process performance, and sludge thermal pre-treatment.
