Abstract:
... Selective removal of phenolic compounds (PCs) from de-oiled sunflower kernel is generally considered a key step for food applications, but this often leads to protein loss. PC removal yield and protein loss were assessed during an aqueous or aqueous ethanol washing process with different temperatures, pH-values and ethanol contents. PC yield and protein loss increased when the ethanol content was  ...

Abstract:
... A successful crop establishment is crucial for sunflower yield. French farmers consider bird damage as an important issue affecting the sunflower establishment. We assessed, through field investigations, the frequency and severity of bird damage symptoms at sunflower emergence. The investigations were carried out across four situations (region x year). The density of viable seedlings at the field ...

Abstract:
... Significant advances in weed mapping from unmanned aerial platforms have been achieved in recent years. The detection of weed location has made possible the generation of site specific weed treatments to reduce the use of herbicides according to weed cover maps. However, the characterization of weed infestations should not be limited to the location of weed stands, but should also be able to disti ...

Abstract:
... BACKGROUND: Phytosterols are plant components with health benefits. Oleaginous seed hybridization can be relevant to increase phytosterols in diet through enriched oils. Sunflower oils obtained by press (PO) and subsequent solvent extraction (SO) from three types of phytosterol‐enriched seeds were characterized. One presented a phytosterol composition of common sunflower seeds, whereas the other t ...

Abstract:
... Heliolactone is one of the earliest identified non-canonical strigolactones. Its concise synthesis was achieved by employing Knoevenagel-type condensation and semi-reduction of a malonate intermediate as the key steps. This synthesis was performed in a non-stereoselective manner, and thus a racemic and diastereomeric mixture of heliolactone was obtained. The developed synthetic route is fairly con ...
