Pol‐NIC: An open database on pollen nutrients, imaging, and contaminants
Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.Pollen is a key component of pollinators' nutrition, yet information on its nutrient composition is largely missing from floral trait datasets. These data paper compiles existing data for 283 plant species and adds new multidimensional analyses of cultivated and wild plants to address major knowledge gaps, along with photos of pollen grain morphology ...

Desamerization of Bitter Jam: Biochemical and Sensory Quality
Journal of Food Quality, Volume 2018, Issue 1, 2018., 2018 This work consists of studying the influence of the desamerization of the mesocarpe on the chemical composition and the sensorial quality of the jam, based on the bitter orange. The results of the various analysis show that desamerization decreases acidity, sugars, protein, and bioactive compound levels (carotenoids, polyphenols, and vitamin C), but ...
