A webGIS-based system for real time shelf life prediction
2016
Technologies to acquire and monitor changes in the product shelf life were described.Four different SL predictive models were considered.A simulated transport using a prototype of Smart Logistic Unit was analysed.Real time shelf life prediction system was implemented in a webGIS platform. Shelf-life (SL) prediction and Least Shelf-life First Out (LSFO) stock strategy are important factors in perishable food supply chain in order to reduce quality and economic losses.In particular, distribution represents one of the main critical phases in logistic chain management and only the introduction of monitoring procedure can allow a reduction in food losses. Literature shows several mathematical mo…
Tubercle disease of sugar beet roots (Beta vulgaris) found in Poland is neither caused by Xanthomonas beticola nor by tumorigenic Agrobacterium/Rhizo…
2018
Symptoms of tubercle disease known also as Xanthomonas gall were noticed in Poland in 2014–2017. Roots with disease symptoms showed the reduction of sucrose content compared to the healthy ones. In the literature, there are two gall diseases described: tubercle disease (also known as Xanthomonas gall) and crown gall, which is caused by Rhizobium radiobacter (syn. Agrobacterium tumefaciens). None of the bacterial strains isolated from the malformed tissues were identified as the bacterial pathogen responsible for causing Xanthomonas gall or crown gall. The result was confirmed by searching for the presence of T-DNA, which was not found. Our conclusion is that the tubercle disease observed in…
Multi-approach metabolomics analysis and artificial simplified phytocomplexes reveal cultivar-dependent synergy between polyphenols and ascorbic acid…
2017
Fruits of the sweet cherry (Prunus avium L.) accumulate a range of antioxidants that can help to prevent cardiovascular disease, inflammation and cancer. We tested the in vitro antioxidant activity of 18 sweet cherry cultivars collected from 12 farms in the protected geographical indication region of Marostica (Vicenza, Italy) during two growing seasons. Multiple targeted and untargeted metabolomics approaches (NMR, LC-MS, HPLC-DAD, HPLC-UV) as well as artificial simplified phytocomplexes representing the cultivars Sandra Tardiva, Sandra and Grace Star were then used to determine whether the total antioxidant activity reflected the additive effects of each compound or resulted from synergis…
Inhibition of NF-κB pathway in LPS-stimulated THP-1 monocytes and COX-2 activity in vitro by berry pomace extracts from five Vaccinium species
2020
BACKGROUND: Berry processing residues called pomaces are rich in polyphenols, sugars, organic acids, and minerals. Polyphenols are reported to reduce the risk of non-communicable diseases, including cardiovascular diseases, cancer, and diabetes mellitus, owing to their anti-inflammatory activity. OBJECTIVE: We aimed to assess the anti-inflammatory properties of five Vaccinium spp. berry pomace extracts using LPS-stimulated THP-1 monocytes and a COX-2 inhibition assay. METHODS: THP-1 monocytes were pre-incubated with chemically characterized bilberry, blueberry, American cranberry, bog cranberry, and lingonberry pomace extracts following LPS stimulation. NF-κB nuclear translocation was asses…
Use of starter cultures ofLactobacillusto induce malolactic fermentation in wine
2017
Background and Aims Oenococcus oeni is the lactic acid bacteria species that best adapts to harsh wine conditions. This species is currently the main component of the malolactic starter cultures used in winemaking. Other species of lactic acid bacteria, however, such as Lactobacillus, can also conduct the malolactic fermentation, especially in low acidity wines. This study aimed to identify suitable Lactobacillus strains and inoculation methods to undertake the malolactic fermentation in wines with pH > 3.5. Methods and Results Six Lactobacillus strains of species L. mali (E4634), L. paracasei (E4539, E4541), L. plantarum (E4538, E4608) and L. satsumensis (E4555) were selected for their goo…
Chemical messages from an ancient buried bottle: Metabolomics for wine archeochemistry.
2017
Restoration works in the old Clunisian Saint-Vivant monastery in Burgundy revealed an unidentified wine bottle (SV1) dating between 1772 and 1860. Chemical evidence for SV1 origin and nature are presented here using non-targeted Fourier Transform Ion Cyclotron Resonance Mass Spectrometry and Nuclear Magnetic Resonance analyses. The SV1 chemical diversity was compared to red wines (Pinot Noir) from the Romanée Saint Vivant appellation and from six different vintages spanning from 1915 to 2009. The close metabolomic signature between SV1 and Romanée Saint Vivant wines spoke in favor of a filiation between these wines, in particular considering the Pinot noir grape variety. A further statistic…
Opuntia Ficus Indica Edible Parts: A Food and Nutritional Security Perspective
2020
Cactus Opuntia ficus indica is widely distributed in (semi-) arid regions. Fruit and cladodes are processed into many food products. Cladodes are used as vegetables, but their main use is flour, wh...
Soybean Seedlings Enriched with Iron and Magnesium - Impact on Germination, Growth and Antioxidant Properties
2018
Abstract Iron (Fe) and magnesium (Mg) deficiency in human diets is a widespread problem observed in various regions of the world. Insufficient Fe uptake results in the development of iron dependent anaemia and depressed physical and intellectual performance. In turn Mg deficiency is associated with alterations in neuromuscular and cardiovascular systems. An emerging alternative to traditional supplementation of these elements in the form of pills, liquids or effervescent tablets, is introduction of fortified food products. In present study we show that preincubation of soybean seeds in Fe and Mg solutions leads to elevated content of these elements in the seedlings. Importantly the pretreat…
Inhibition of succinate oxidation by the herbicide UKJ72J
1985
Abstract The inhibitory activity of the herbicide UKJ72J on succinate oxidation in mitochondria from various plant species was studied. In monocotyledons (Gramineae: wheat, oat, maize; Liliaceae: onion, leek) succinate oxidation was affected only at high concentrations. Among dicotyledons widely differing sensitivities were found: in Solanaceae (tomato, potato, tobacco), Leguminosae (mung bean, soybean) and Compositae (sunflower) I 50 concentrations for UKJ72J inhibition were below 55 μM. In Cruciferae (turnip, cauliflowers Chenopodiaceae (lambsquarter, beetroot) and Compositae (endive) I 50 were between 100 and 250 μM, whereas in Rosaceae (apple, pear) and Umbelliferae (carrot, fennel) I 5…
Modelling the inhibitory effect of copper sulfate on the growth of Penicillium expansum and Botrytis cinerea
2011
Aims: This study aimed to investigate the effect of copper sulfate (from 0 to 8 mmol kg−1) on radial growth rate and lag time of two moulds responsible for vine grapes spoilage: Penicillium expansum strain 25·03 and Botrytis cinerea, strains BC1 and BC2. Methods and results: A new model was developed to describe tailing and shoulders in the inhibition curves. Because of tailing, the minimum inhibitory concentration (MIC), was not defined as the concentration at which no growth was observed, but as the concentration at which the lag time was infinite. The concentrations at which μ = μopt/2, (Cu50), were in the range of 2·2–2·6 mmol kg−1. Radial growth rate of P. expansum and the reciprocal…
