Exploring Italian Autochthonous L. Accessions: Pomological, Physicochemical, and Aromatic Investigations.

Autochthonous Italian pomegranate accessions are still underexplored, although they could be an important resource for fresh consumption, processing, and nutraceutical uses. Therefore, it is necessary to characterize the local germplasm to identify genotypes with desirable traits. In this study, six old Italian pomegranate landraces and a commercial cultivar (Dente di Cavallo) were investigated, evaluating their fruit pomological parameters, physicochemical (TSS, pH, TA, and color) characteristics, sugar content, and aromatic profiles (HeadSpace Solid-Phase MicroExtraction (HS-SPME)) coupled with Gas Chromatographyass Spectrometry (GC-MS) of pomegranate juices.

Exploring the Volatile Composition and Antibacterial Activity of Edible Flower Hydrosols with Insights into Their Spontaneous Emissions and Essential Oil Chemistry.

In the circular economy framework, hydrosols, by-products of the essential oil industry, are gaining attention for their potential in waste reduction and resource reuse. This study analyzed hydrosols from six edible flowers, investigating their chemical composition (VOC-Hyd) and antibacterial properties alongside volatile organic compounds of fresh flowers (VOC-Fs) and essential oils (EOs). exhibited ketones as major VOC-Fs (62.

Phytonutritional compounds and antioxidant activity of eight new edible flowers.

In the last years, special attention has been given to the nutritional properties of food, and the edible flowers (EFs) represent an uncommon fresh product to characterise, with the aim to explore new species with peculiar aesthetic and the aromatic features. This work investigated some nutritional properties of eight new EFs, such as A.DC.

From Hop to Beer: Influence of Different Organic Foliar Fertilisation Treatments on Hop Oil Profile and Derived Beers' Flavour.

Foliar fertilisation is known to influence the physiological response of (hop plants), but its effect on the flavour profile of beer still has to be investigated. By comparing the effects of four fertilisation treatments, this study aims at determining whether different foliar fertilisation treatments have a significant impact on hop plants' aromatic quality and that of the beer produced. Hop cones harvested from each experimental treatment were brewed to obtain five single dry-hopped beers, which were subsequently analysed.

The colors of Tuscan bee pollen: phytochemical profile and antioxidant activity.

Bee pollen's nutritional and beneficial health properties depend on the botanical origin and storage conditions. Palynological analysis determines the botanical composition of the multiflora and colour fractions. This study aimed to characterize the phytochemical profile and antioxidant activity of Tuscan bee pollen stored at freezing temperature for 2 years to verify the preservation of nutraceutical properties of the multiflora and colour fractions.

Senescence in dahlia flowers is regulated by a complex interplay between flower age and floret position.

Mechanisms regulating flower senescence are not fully understood in any species and are particularly complex in composite flowers. Dahlia ( Cav.) florets develop sequentially, hence each composite flower head includes florets of different developmental stages as the whole flower head ages.

Exploring volatile aroma and non-volatile bioactive compounds diversity in wild populations of rosemary (Salvia rosmarinus Schleid.).

Ninety-five rosemary (Salvia rosmarinus Schleid.) genotypes, representing 24 wild populations, collected in different geographical areas in Italy and then cultivated under homogeneous environmental conditions, were characterised for volatile organic compounds (VOCs) and three main non-volatile phenolic diterpenes (carnosic acid, carnosol) and acids (rosmarinic acid). Cluster analysis of chemical data highlighted the occurrence of three main groups of populations: one with high levels of verbenone, α-pinene, bornyl acetate, carnosic acid and carnosol, a second one with relatively high levels of camphor and a third one with high levels of 1,8-cineole, β-pinene and sesquiterpenes.

Postharvest Treatments on Sensorial and Biochemical Characteristics of Willd Edible Flowers.

Edible flowers (EFs) are currently consumed as fresh products, but their shelf life can be extended by a suitable drying technique, avoiding the loss of visual quality and valuable nutraceutical properties. Willd is a common ornamental bedding plant, and its leaves and flowers are edible. In this work, red flowers were freeze-dried (FD) and hot-air dried (HAD) at different temperatures.

Valorization of a Waste Product of Edible Flowers: Volatile Characterization of Leaves.

(1) Background: The leaves of some plants are reported for their culinary uses, while in edible flowers, they are one of the discarded products in the supply chain. We investigated the volatile profile (VP) and the essential oil (EO) compositions of leaves from 12 Lamiaceae species, of which nine belong to the Mentheae tribe and three to the Ocimeae tribe. (2) Methods: Phytochemical analyses were performed using a GC-MS instrument.

Extract Acts as Biostimulant and Modulates Metabolites and Hormone Balance in Basil ( L.) and Parsley ( L.).

Natural elicitors from macroalgae may affect plant secondary metabolites. Ulvan is a sulfated heteropolysaccharide extracted from green seaweed, acting as both a plant biotic protecting agent, and a plant elicitor, leading to the synthesis of signal molecules. In this work, the aqueous extract of L.

Combined effect of silicon and non-thermal plasma treatments on yield, mineral content, and nutraceutical proprieties of edible flowers of Begonia cucullata.

Edible flowers are becoming popular as a nutraceutical and functional food that can contribute to human nutrition with high antioxidant molecules and mineral elements. While comparative studies between different flower species have been performed, less is known about the best agronomical practices to increase yield and nutraceutical proprieties of blooms. Silicon stimulates plant resistance against stress and promotes plant growth while non-thermal plasma (NTP) technology has been applied for the disinfection and decontamination of water, as well as for increasing plant production and quality.

Small Functional Foods: Comparative Phytochemical and Nutritional Analyses of Five Microgreens of the Brassicaceae Family.

Microgreens are the seedlings of herbs and vegetables which are harvested at the development stage of their two cotyledonary leaves, or sometimes at the emergence of their rudimentary first pair of true leaves. They are functional foods, the consumption of which is steadily increasing due to their high nutritional value. The species of the Brassicaceae family are good sources of bioactive compounds, with a favorable nutritional profile.

Salinity-Induced Changes of Photosynthetic Performance, Lawsone, VOCs, and Antioxidant Metabolism in L.

The present study aimed to elucidate the salinity influence on the bioactive metabolites of L. (henna) plants. Young henna plants were cultivated under salinity stress with two NaCl concentrations (75 mM and 150 mM) in controlled environmental conditions and the leaves were investigated to check their adaptative responses.

Phytonutritional Content and Aroma Profile Changes During Postharvest Storage of Edible Flowers.

Bioactive Compounds and Aroma Profile of Some Lamiaceae Edible Flowers.

Edible flowers are consumed for their appearance, colours, nutritional and healthy properties, but the use is limited by the actual number of the species. Seven edible flowers of the Lamiaceae family (Ocimeae and Mentheae tribes) were investigated: 'Fireball', 'Six Hills Giant', 'Blue Spice', 'Cinnamon', , and 'Hot Lips'. Total soluble sugars, proteins, polyphenols, carotenoids, ascorbic acid and antioxidant activity were detected.

Volatilomic Analysis of Four Edible Flowers from Genus.

Volatilomes emitted from edible flowers of two species of ( (A.Gray) Lint & Epling, and (Kunth) Lint & Epling) and from two hybrids ( 'Arcado Pink' and 'Blue Boa') were investigated using a solid-phase microextraction technique as well as the extraction of its essential oils. Oxygenated monoterpenes were almost always the predominant class (>85%) of volatile organic compounds (VOCs) in each sample of , .
