Abstract In this paper volatile organic compounds (VOCs) from durum wheat cultivars and landraces were analyzed using PTR-TOF-MS. The aim was to characterize the VOC’s profile of wholemeal flour kernel find out if any VOCs specific varieties sample matrices. VOC data is accompanied by SDS-PAGE analyses storage proteins (gliadins glutenins). Statistical carried both on signals obtained MS protein profiles. difference between two or preparations same - matrices, in case vs can be very subtle;...
Abstract Plants emission of Volatile Organic Compounds (VOCs) is involved in a wide class ecological functions, as VOCs play crucial role plants interactions with biotic and abiotic factors. Accordingly, they vary widely across species underpin differences strategy. In this paper, spontaneously emitted by 109 plant (belonging to 56 different families) have been qualitatively quantitatively analysed order provide an alternative classification species. particular, using bipartite networks...
Abstract BACKGROUND The aquafeed sector has been replacing conventional dietary ingredients with more economic and eco‐friendly ingredients. Insects embody a promising alternative as result of being highly nutritious showing traits leading to circular bioeconomy. Atlantic salmon ( Salmo salar L.) at the sea‐water stage were fed diets partial or complete substitution fishmeal meal Hermetia illucens larvae reared on media containing Ascophyllum nodosum mixed organic wastes (60:40). present...
In this paper volatile organic compounds (VOCs) from Tuber magnatum fruiting bodies were analyzed using a PTR-TOF-MS instrument. The aim was to characterize the VOC's profile of and identify if any VOCs specific season geographical areas. Multiple factorial analysis (MFA) carried out on signals obtained by MS. Experiments ITS region sequencing proved that T. life cycle includes formation at two different times year. profiles diverge when seasonal productions are considered. Using PTR-TOF-MS,...
Plants activate defense-related pathways in response to subtle abiotic or biotic disturbances, changing their volatile profile rapidly. How such perturbations reach and potentially affect neighboring plants is less understood. We evaluated whether brief light touching had a cascade effect on the of volatiles gene expression focal plant untouched plant. Within minutes after contact, Zea mays showed an up-regulation certain defense genes increased emission specific that primed plants, making...
Chili is a globally significant spice used fresh or dried for culinary, condiment, and medicinal purposes. Growing concerns about food safety have increased the demand high-quality products non-invasive tools quality control like origin tracing assurance. Volatile analysis offers rapid, comprehensive, safe method characterizing various products. Thus, this study aims to assess impact of drying process on aromatic composition
Evidence suggests that heavy-metal tolerance can be induced in plants following pre-treatment with non-toxic metal concentrations, but the results are still controversial. In present study, tobacco were exposed to increasing Zn2+ concentrations (up 250 and/or 500 μM ZnSO4) or without a 1-week acclimation period 30 ZnSO4. Elevated was highly toxic for plants, and after 3 weeks of treatments there marked (≥50%) decline plant growth non-acclimated plants. Plant acclimation, on other hand,...
Proton transfer reaction-mass spectrometry (PTR-MS), in its recently developed implementation based on time-of-flight mass (PTR-TOFMS), was used to rapidly determine the volatile compounds present fruits of Capsicum spp.We analyzed organic emission profile freshly cut chili peppers belonging three species and 33 different cultivars. PTR-TOFMS data, with appropriate advanced multivariate class-modeling approaches, perfectly discriminated among (100% correct classification validation set). VIP...
SPME-GC-MS and PTR-ToF-MS techniques were applied to describe the content of volatile flavor compounds in a craft beer before after adding spirulina. The obtained results showed that profile two samples differed. Furthermore, chemically characterize biomass spirulina, derivatization reaction followed by GC-MS analysis was performed, highlighting high molecules belonging different chemical classes, such as sugars, fatty acids carboxylic acids. A spectrophotometric total polyphenols tannins,...
In this work, Arthrospira platensis grown in Tuscany, Italy, was investigated using different analytical approaches to characterize its volatile and non-volatile chemical composition. The results showed the presence of a high number organic compounds (VOCs) such as hydrocarbons, furans, sulfides, alkanes, aldehydes, alcohols, ketones, esters belonging other classes fatty acids, alcohols sugars. Furthermore, proximal composition analysis also performed determine protein, fat, carbohydrate ash...
Due to the globalization of coffee trade, ensuring safety and traceability has become a critical challenge, prompting global authorities implement new systems enhance quality identification protect consumers from fraud. Aroma is crucial parameter in evaluation differentiation coffees, influenced by factors such as genetics, origin, post harvesting process, roast level, brewing method. This paper provides, for first time, comprehensive overview volatile fingerprints specialty categorized...
Cerato-platanin (CP) is the founder of a fungal protein family consisting in non-catalytic secreted proteins, which work as virulence factors and/or elicitors defense responses and systemic resistance, thus acting PAMPs (pathogen-associated molecular patterns). Moreover, CP has been defined an expansin-like showing ability to weaken cellulose aggregates, like canonical plant expansins do. Here, we deepen knowledge on PAMP activity by use multi-disciplinary approach: proteomic analysis, VOC...
The influences of various factors, including the symbiosis established with roots specific tree species, on production volatiles in fruiting bodies Tuber magnatum have not been investigated yet. Volatiles T. were quantitatively and qualitatively determined by both PTR-MS GC-MS order to compare accuracy two methods. An electronic nose was also used characterize truffle samples. influence environmental changes antioxidant capabilities determined. Statistically significant differences found...
Truffles are symbiotic fungi that develop underground in association with plant roots, forming ectomycorrhizae. They primarily known for the organoleptic qualities of their hypogeous fruiting bodies. Primarily, Tuber magnatum Pico is a greatly appreciated truffle species mainly distributed Italy and Balkans. Its price features mostly depending on its geographical origin. However, genetic variation within T. has been only partially investigated as well adaptation to several environments.Here,...
