Explaining surface interactions for common associated gangues of rare earth minerals in response to the oxalic acid

International Journal of Mining Science and Technology, 2018
In the flotation of rare earth minerals (REMs), oxalic acid is reportedly acting both as a depressant and pH modifier. Although results of testing have established the significance of oxalic acid in the flotation process, its specific role in either the ...

Effect of thermosonication on the UHPLC‐QTOF‐IMS‐based metabolomic profile of orange juice

JSFA reports, EarlyView.
Abstract Background This study investigated the impact of thermosonication on the metabolomic profile of orange juice to understand processing‐induced alterations in bioactive compounds and quality attributes. Results Moderate thermosonication at 45°C preserved structural siloxanes and certain amino acids, whereas higher temperatures between 60 and 75 ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Polyamine treatments: an effective strategy to improve crop yield and fruit colour and to preserve quality of ‘Mollar de Elche’ pomegranate fruit during storage at chilling temperatures

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change in Spain is altering the optimal conditions for producing high‐quality ‘Mollar de Elche’ pomegranate fruit, due to reduced colour development in husk and arils. In addition, the pomegranate requires storage above 7–10 °C, depending on cultivar, to preserve its quality because it is susceptible to chilling injury (CI ...

Secondary formation of oxalic acid and related organic species from biogenic sources in a larch forest at the northern slope of Mt. Fuji

, 2017
To better understand the formation of water-soluble organic aerosols in the forest atmosphere, we measured low molecular weight (LMW) dicarboxylic acids, oxocarboxylic acids, α-dicarbonyls, unsaturated fatty acids (UFAs), and water-soluble organic carbon

Combined effects of prohexadione‐calcium and growing environment on sweet cherry fruit quality and postharvest performance

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sweet cherry (Prunus avium L.) is a high‐value fruit crop, but its commercial success is often limited by poor pigmentation, reduced firmness, and short shelf life. This study evaluated the effects of preharvest applications of prohexadione‐calcium (1.5 L ha−1) on fruit quality and storage performance in lowland and hilly orchards ...
