Current insights into date by-product valorization for sustainable food industries and technology

Abstract

The date palm holds immense significance in the socio-economic fabric of countries where it is extensively cultivated. The plant and its derivatives boast diverse nutritional and functional properties, contributing to...

Date pomace polysaccharide: ultrasonic-assisted deep eutectic solvent extraction, physicochemical properties, biological activities, gut microbiota modulation, and rheological properties

“…Date palm fruits, extensively cultivated and consumed across regions such as Africa, the Middle East, the Gulf Cooperation Council territories, and Central Asia, have experienced a marked increase in utilization owing to their beneficial health properties [1]. This augmented consumption encompasses not only the fruit, but also extends to derivative products including syrups, juices, jams, and pastes, particularly utilizing dates deemed subpar in quality.…”

“…This augmented consumption encompasses not only the fruit, but also extends to derivative products including syrups, juices, jams, and pastes, particularly utilizing dates deemed subpar in quality. Dates, being repositories of vital nutrients, are a staple component within the dietary frameworks prevalent in MENA regions [1]. The agricultural and food industries contribute to significant by-product generation; nonetheless, these by-products present opportunities for resource recovery, promoting sustainability and the adoption of circular economies [2].…”

“…Currently, date pomace (DP) is primarily utilized within animal feed formulations, despite a large proportion being discarded, which leads to environmental detriments. The nutrient matrix of DP, abundant in polysaccharides, proteins, phenolic compounds, and essential vitamins, renders it an opportune candidate for incorporation in animal feeds and as a substrate for the synthesis of high-value products [1]. Scientific investigations have predominantly concentrated on the phenolic content within dates, while the polysaccharides-complex carbohydrates composed of monosaccharide units connected via glycosidic linkages and sourced from various biological origins, including plant, animal, and microbial-have received less focus [3,4] Polysaccharides, functioning as dietary fibers, emulsifiers, and stabilizers, are pivotal in food and pharmaceutical industries due to their intrinsic bioactive properties that may confer antitumor, antiglycation, and cardioprotective effects [5,6].…”

“…To date, the endeavor of extracting polysaccharides from date pomace (UPS) utilizing an ultrasound-assisted deep eutectic solvent method and the subsequent impact on their physicochemical, structural, and biofunctional properties has not been documented. This study aimed to (1) investigate the extraction of UPS using ultrasound-assisted DES and conduct a thorough physicochemical characterization;…”

The Potential of Using Bisr Date Powder as a Novel Ingredient in Biscuits Made of Wheat Flour Only or Mixed with Barley

“…Using dates and their byproducts to enhance the nutritional and functional quality of bread and bakery goods has become more popular in recent decades. Because date fruit and its byproducts naturally contain a variety of groups of phytochemicals, the scientific world is beginning to take notice of the date fruit and its byproduct’s appropriateness for use in health-promoting functional food composition [ 12 ].…”
