Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.

Impact of spring rape varieties on protein extraction from press cake, emulsifying properties and antinutrient content

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Rapeseed is the second most cultivated oilseed globally after soybean and a protein‐rich press cake is generated after liberation of the oil. However, its use in food applications is limited by high levels of anti‐nutrients such as glucosinolates and phytic acid. Although differences between botanical varieties are known, controlled

Chemical stabilization of glass microfiber type F filters for measuring particulate phosphorus using the extra high‐temperature dry combustion method

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of particulate phosphorus is critical for understanding biogeochemical processes in aquatic systems. Extra high‐temperature dry combustion at 800°C improves phosphorus recovery by ~ 11% compared to lower‐temperature methods.

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, EarlyView.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.
