Food waste presents a continuous challenge for the food industry, leading to environmental pollution and economic issues. A substantial amount of waste, including by-products from fruits vegetables, non-edible items, other materials, is produced throughout supply chain, production consumption. Recycling valorizing perishable goods emerging as key multidisciplinary approach within circular bio-economy framework. This rich in raw by-products, can be repurposed natural source ingredients. Researchers increasingly focus on biomass valorization extract use components that add significant value. Traditional methods extracting these bio-compounds typically require solvents are time-consuming, underscoring need innovative techniques like ultrasound (US) extraction. Wastes processing vegetables industry used develop functional foods edible coatings, offering protection against various factors. comprehensive review paper discusses items using US technology, not only valuable but also treat wastewater beverage industry. It covers application biomolecules recovered this process development packaging.

Comparison of phenolic composition in Australian-grown date fruit (Phoenix dactylifera L.) seeds from different varieties and ripening stages

Food Research International, Год журнала: 2024, Номер 181, С. 114096 - 114096

Опубликована: Фев. 3, 2024

In this research, different seeds of Australian-grown date palm (Phoenix dactylifera L.) were studied to evaluate the antioxidant potential and analyze their phenolic constituents. Phenolic compounds extracted from various varieties at ripening stages. Eight (Zahidi, Medjool, Deglet nour, Thoory, Halawi, Barhee, Khadrawy, Bau Strami) three stages (Kimri, Khalal, Tamar) investigated in study. Date Khalal (9.87-16.93 mg GAE/g) Tamar (9.20-27.87 showed higher total content than those Kimri stage (1.81-5.99 GAE/g). For assays like DPPH, FRAP, ABTS, RAP, FICA, TAC, also stage. However, (55.24-63.26 TE/g) expressed radical scavenging activity (13.58-51.88 (11.06-50.92 characterized using LC-ESI-QTOF-MS/MS, revealing presence 37 compounds, including 8 acids, 18 flavonoids, 11 other compounds. Further, quantified LC-DAD, that Zahidi variety exhibited highest during contrast, stages, nour Medjool displayed concentrations The results indicated an increase after stage, with significant variations observed among varieties.

Active food packaging films from alginate and date palm pit extract: Physicochemical properties, antioxidant capacity, and stability

Food Science & Nutrition, Год журнала: 2022, Номер 11(1), С. 555 - 568

Опубликована: Окт. 6, 2022

Abstract Date palm pits are highly available and inexpensive date by‐products, representing a valuable source of natural antioxidants, particularly phenolic compounds. pit extract (DPPE) was prepared from these waste products characterized for its content in vitro antioxidant activity. Profiling DPPE by liquid chromatography coupled with mass spectrometry (LC/MS) showed the presence dimers trimers (epi)catechin as main constituents. Alginate‐based films four increasing concentrations (10%, 20%, 30%, 40% w/w) were casting method. incorporation reduced solubility values alginate 37%–64% their surface wettability 72%–111%. The 10% improved water vapor barrier properties increased tensile strength (TS) elongation at break (%E) more than 23%, 50%, 45%, respectively. film containing lowest loss (32%), DPPH (1,1‐diphenyl‐2‐picrylhydrazyl) scavenging activity (38%), ferric reducing power (FRAP) (30%) after storage 3 months.

Extraction, Characterization, and Antioxidant Activity of Polysaccharides from Ajwa Seed and Flesh

Separations, Год журнала: 2023, Номер 10(2), С. 103 - 103

Опубликована: Фев. 2, 2023

The date palm has been cultivated in dry and hot areas of the planet for much human history. In Kingdom Saudi Arabia, dates are main crop used as a source food. Among several species fruits, Ajwa AL-Madinah is unique, growing only Al-Madinah geographical region. traditional medicine due to its abundant active components therapeutic properties. This study investigates structural properties antioxidant effects water-soluble polysaccharides extracted from flesh seed. were isolated by two techniques including water ultrasonic extraction. After isolation partial purification, physicochemical four samples seed studied FTIR, solid-state NMR, elemental analysis, mass spectrometry. Several radical scavenging experiments combined activity polysaccharide compounds. FTIR NMR results showed structure typical heterogeneous polysaccharides. Mass spectrometry revealed that composed mainly mannose, glucose, galactose, xylose, arabinose, galacturonic acid, fucose. addition, composition compared. activity, with 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging, Fe chelating ability, hydroxyl free 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging. These highlight their potential be useful nutritional element or supplemental medication.

Appraised for being one of the oldest staple nutritive foods mainly in Arabian Peninsula, date palm tree (Phoenix dactylifera L.), is a crop native to subtropical and tropical regions Southern Asia Africa. Different parts have been extensively studied their nutritional therapeutic properties. Despite an array publications on tree, there has no attempt compile single study traditional uses, value, phytochemical profile, medicinal properties as well potential different plant functional food. Therefore, this review endeavors systematically scientific literature highlight uses fruit around world, profile several A total 215 studies was retrieved (traditional (n = 26), 52), 84)). Scientific articles were further categorized vitro 33), vivo 35), clinical 16) evidences. Date seeds found be effective against E. coli Staphylococcus aureus. Aqueous pollen used manage hormonal problems boost fertility. Palm leaves showed anti-hyperglycemic effects via inhibition α-amylase α-glucosidase. Unlike previous studies, highlighted roles all provided insights into various mechanism action bioactive compounds. Although shreds evidence growing over years, still dearth concerning validation other provide strong uses. In conclusion, P. can regarded potent with prophylactic should explored alleviate burden both communicable non-communicable diseases.
