Morphological, nutraceutical and sensorial properties of cultivated Fragaria vesca L. berries: influence of genotype, plant age, fertilization treatment on the overall fruit quality
Sucrose, glucose, fructose, citric, malic, ascorbic (AA) and dehydroascorbic (DHAA) acids, total polyphenols (TP), radical scavenging activity (RSA), physicochemical and sensorial properties were determined on F. vesca Alpine (ALP) and Regina delle Valli (RDV) berries in relation to plant age and fertilisation treatment (Effective Microorganism Technology, EMT vs. traditional fertilization, TFT). ALP berries had a sum of AA and DHAA about 20% lower and TPs about 30% higher than RDV. Plant age affected most physicochemical parameters, sugars and organic acids, as well as sensorial appreciation, being them generally higher in berries produced in the second year. TPs were not affected by plant age. EMT produced an increase of 50%, 70% and 20% for TP, organic acids and RSA, respectively. Although changes in berry quality are expected with plant age, EMT cultivation of ALP should be preferred to the growth of RDV under TFT, to obtain fruits more valuable from the nutraceutical viewpoint
Enrichment of organic pollutants in the sea surface microlayer (SML) at Terra Nova Bay, Antarctica: influence of SML on superficial snow composition.
Concentrations of dissolved and particle-associated n-alkanes, phthalates and polycyclic aromatic
hydrocarbons (PAHs) were measured in sea surface microlayer (SML) and sub-surface water (SSL) samples
collected in the coastal area of Terra Nova Bay, Antarctica, during the Austral spring 1998/1999. SML
concentrations of the selected organic compounds were higher than SSL values and the enrichment factors
were greater in the particulate phase than in the dissolved phase. During the same campaign, ‘‘fresh’’ snow
samples, collected at different altitudes (from sea level up to 2670 m) near the coast on Mt Melbourne,
immediately after a snowy event, were analysed in order to provide more information on air/sea exchange
processes. The same classes of organic compounds found in sea water were also present in ‘‘fresh’’ snow
samples. The surfactant fluorescent organic matter (SFOM), adsorbed on the microdrop aerosol surface,
could be considered the main constituent of the enrichment and the carrier at higher altitudes of organic
compounds. In fact, hydrocarbons (n-alkanes and PAHs), which are not surfactants like phthalates, could
interact with SFOM and follow the same fate
