Effects of fertigation by elicitors enriched in amino acids from vegetal and animal origins on Syrah plant gas exchange and grape quality

White wine processing by UHPH without SO2. Elimination of microbial populations and effect in oxidative enzymes, colloidal stability and sensory quality

“…Sample preparation and chromatography conditions were made according to Roda et al (2019). One hundred milliliters of centrifuged (15 min at 6.000 rpm) grape juice was doped with 100 µL of 2-octanol (as internal standard), and passed through a SPE cartridge (Solid Phase Extraction) Bond Elut ENV of 500 mg and 6 mL (Agilent Technologies, Santa Clara, CA, USA).…”

An overview about the impacts of agricultural practices on grape nitrogen composition: Current research approaches

“…These results suggest that the formulation of the nutrient can be of a wide importance since both treatments received 80 kg N/ha (Howell & Conradie, 2013). Fertigation applied to Syrah grapevines using elicitors enriched with amino acids improved gas exchange balance and N assimilation, while increased yeast assimilable nitrogen and also enhanced the aromatic profile of the grapes (Roda et al, 2019). Thus, a soil-plant-atmosphere assessment throughout the whole season allows accurate irrigation/fertigation practices minimizing fertilizer leaching losses, therefore reducing the negative environmental impacts of irrigation (Fuentes et al, 2008).…”

The Light Struck Taste of Wines

“…According to the authors, the results obtained are comparable to those obtained by HPLC methods. The other alternative involves the use of UPLC which has become the modern HPLC showing higher sensitivity and chromatographic efficiency with a consequent run-time decrease [63].…”
