Structural characteristics of alkaline treated fibers from date-pits: Residual and precipitated fibers at different pH

Applications of date pits in foods to enhance their functionality and quality: A review

“…Date pits are a rich source of fibers, with fiber content varying between 60 and 80 g/100 g total weight (Habib and Ibrahim, 2009;Ataye et al, 2011;Habib et al, 2017;Metoui et al, 2019;Alyileili et al, 2020a;Al-Khalili et al, 2021). As lignocellulosic biomaterial, the insoluble fiber content consists of cellulose, hemicellulose, and lignin, .…”

“…In addition, the separation of crystalline and amorphous fractions of date pits could have wider applications. For example, crystalline fibers could be used to enhance the formation of the desired level of crust in bread, while amorphous fractions could increase the softness of the crumb (Al-Khalili et al, 2021. Date pits could function as a plant-source protein for use in food and other bioproducts.…”

Preparation of Cellulose Nanocrystals from Jujube Cores by Fractional Purification

“…Jujube cores are lignocellulosic materials containing phenols, polysaccharides, oil, and other components, of which cellulose, lignin, and hemicellulose are the main components [ 7 , 8 ]. At present, the utilization of jujube cores is mainly focused on the use of jujube cores as adsorbents for water purification [ 9 ], activated carbon [ 10 ], biofuels [ 11 ], and functional components such as polyphenol extraction [ 12 , 13 ].…”

“…The abundant fibrous material in jujube cores makes them a competitive material for developing different types of fibers. At present, a small number of scholars have studied the extraction of cellulose from jujube cores [ 5 , 8 , 31 ]. Among them, Wahib et al [ 32 ] studied two methods to extract CNCs, and compared the crystallinity of the extracted CNCs and the economic cost of the two extraction methods.…”
