The seafood industry is often left out of the food waste discussion, but this sector no exception, as it generates large amounts various by-products. This study aimed to explore potential microwave-assisted extraction (MAE) technique obtain high-quality oil from fish independent variables, which were time (1–30 min), microwave power (50–1000 W), and solid/liquid ratio (70–120 g/L) combined in a 20-run experimental design coupled with response surface methodology (RSM) for process...
Germination is a natural, simple, and economical process used to improve the quality of nutritional technological grains. In this study, native sprouted sorghum flours were characterized regarding their properties (particle size distribution, water, oil absorption capacity, swelling power solubility, microscopy starch granules, pasting thermal properties). Nutritional phytochemical characterization profiles, including free sugars, fatty acids, organic tocopherols, phenolic compounds,...
Underutilized plant species such as Asteriscus graveolens (Forssk.) Less., Haloxylon scoparium Pomel, and Ruta chalepensis L. have been historically valued in traditional medicine for their potential health benefits. These present an untapped source of bioactive compounds with significant applications the food pharmaceutical industries, including development functional foods additives. Recent advances processing introduced innovative methods, pulsed electric fields (PEFs), to enhance...
This study provides a comprehensive characterization of Physalis peruviana L., covering the nutritional composition fruit and phytochemical profiles in vitro bioactive properties berry calyx extracts. The fresh stood out as source dietary fiber (5.16 g/100 g) is low fat (0.49 g). A 100-g serving also contained notable amounts ascorbic acid (32.0 mg), tocopherols (2.34 potassium (253 phosphorus (45 magnesium (20 mg). HPLC-DAD-ESI/MS analysis tentatively identified five physalin derivatives...
This study evaluated the effects of three irrigation treatments (control (rain-fed plants), deficit (DI: 50% maximum field capacity), full (FI: 100% capacity)), and two crop-management (with or without crop rotation with bean, CR, NCR, respectively) on plant growth chemical composition C. spinosum. The results indicated that combined increased weight leaves per plant, followed by rain-fed plants for same treatment. Additionally, these factors significantly influenced nutritional profile,...
<italic>C. vulgaris</italic> inflorescences revealed myricetin derivatives as the main compound and polar extracts higher bioactivities, preserving vaginal microbiota.
Humans often respond to sensory impulses provided by aromas, and current trends have generated interest in natural sources of fragrances rather than the commonly used synthetic additives. For first time, resulting aroma a selected culture Thymus mastichina L. was studied as potential food ingredient. In this context, dried (DR) fresh (FR) samples were submitted carbon dioxide (CO2) supercritical extraction (SFE) hydrodistillation (HD) methods. The extracts characterised according their...
A variety of the classic green tea plant, Camellia sinensis, was developed and is exclusive to Kenya. Due high content anthocyanin polyphenols in its leaves, beverage obtained from this purple color origin name tea. This work had two main purposes. The first one identify quantify major a hot water aqueous extract leaves. second test hypothesis if capable inhibiting triglyceride absorption considering that polyphenolics have been frequently associated antilipidemic effects. Parallel...
Quince (Cydonia oblonga Mill.) is an astringent fruit widely processed into marmalade and other sweets through processes that discard the peel as a by-product. Therefore, this study was performed to characterize quince composition in nutrients phytochemicals evaluate its vitro biological activity, following "zero waste" approach. The dry powder particularly rich fiber (20.2 g/100 g), fructose (34 malic acid (7.2 potassium (692 mg/100 g). Extracts prepared by dynamic hydroethanolic maceration...
Due to a lack of innovative valorization strategies, pomegranate processing generates significant amount residues with negative environmental footprint. These by-products are rich source bioactive compounds functional and medicinal benefits. This study reports the leaves as ingredients using maceration, ultrasound, microwave-assisted extraction techniques. The phenolic composition leaf extracts was analyzed an HPLC-DAD-ESI/MSn system. extracts’ antioxidant, antimicrobial, cytotoxic,...
Grumixama, Eugenia brasiliensis Lam., is a Brazilian berry little explored commercially and scientifically. However, local small producers market this fruit in the form of frozen pulp, which generates bioresidues, composed seeds peels. With view to propose strategies for valuing grumixama, study aimed determine chemical composition assess bioactivities hydroethanolic extracts whole residue (GR), seed (GS) peel (GP) fractions E. brasiliensis. From results, GP had highest concentration organic...
The chemical composition of extracts (CEs) and essential oils (EOs) from Tetradenia riparia leaves, flower buds, stems was analyzed. Antiproliferative activity against tumor cell lines, NO production inhibition, antioxidant antiviral activities were assessed. CEs contained flavonoids, phenolic acids, coumarins, saturated fatty acids. EOs included monoterpenes, oxygenated sesquiterpenes, diterpenes. inhibition ranged 76 to 247 µg mL−1, antiproliferative exhibited GI50 between 20 >204 with...
Cardoon (Cynara cardunculus var. altilis) blades were collected at sixteen sampling dates (B1-B16) to study the influence of phenological growth stage on phenolic composition and biological properties. Twenty compounds identified, among which trans 3,4-O-dicaffeoylquinic acid, 5-O-caffeoylquinic luteolin-O-hexoside (39.6, 42.6, 101.0 mg/g extract, respectively) main compounds. Immature (B3) had a higher content (178 extract) greater ability inhibit formation thiobarbituric acid reactive...
In this work, several benzothiazole-based aminosquaraine dyes, displaying strong absorption within the so-called phototherapeutic window (650⁻800 nm), were synthesized. The ability, of all new to generate singlet oxygen was assessed by determining correspondent phosphorescence emission and through comparison with a standard. quantum yields generation determined exhibited be strongly dependent on nature amino substituents introduced in squaric ring. photodynamic activity synthesized dyes...
Consumer demand for natural and healthier products has led to an increasing interest in the bioactive therapeutic properties of plant extracts. In this study, we evaluated phenolic compounds profile, bioactivities, toxicities extracts from eight European flora species, including Calendula officinalis L., Calluna vulgaris (L.) Hull, Hippophae rhamnoides Juglans regia Mentha cervina Rubus idaeus Sambucus nigra Vitis vinifera L. The aim was identify potential preservatives origin. Phenolic were...
The bioactive properties of underutilized corks such as Quercus cerris cork and planted suber in the Eastern Mediterranean are not well-known but crucial developing lignocellulosic biorefineries. To assess their biological potential, hydroethanolic extracts were analyzed for phenolic composition, antioxidant, antiproliferative, antimicrobial activities, hepatoxicity, well NO-production inhibition. Here, we show that a mild extraction Q. yielded 3% extracts. composition was similar both...
Cardoon is a multi-purpose crop with several industrial applications, while the heads (capitula) are edible and commonly used in various dishes of Mediterranean diet. Several reports literature study chemical composition plants parts (leaves, flower stalks, bracts, seeds) aiming to applications bio-waste, whereas for heads, most studies limited bioactive properties at stage. In present study, cardoon were collected six different maturation stages their was evaluated order determine effect...
