“…As a result, this by-product could be a potential source of cellulose to obtain cellulose nanocrystals. The Klason lignin content of DP was comparable to the value obtained by Rosado et al (47) from the rind of the papyrus (C. papyrus L.) plant, accounting for 27.0% of the dry material, while lignin content in the pith was significantly lower, accounting for only 15.7% of the dry material.…”

“…Finally, it is important to point out that K is the main mineral present in horchata, followed by P, Mg, and Ca (58). Potassium was also found in a significant concentration in DP, and it has been reported to be one of the main minerals present in dried plants (2,47,59). As a result of this work, it can be concluded that DP has a great potential to be used as a rich source of important minerals in nutrition applications.…”

“…The moisture content of DP was 5.4 ± 0.1%, while protein and fat contents were 1.6 ± 0.2 and 1.1 ± 0.2%, respectively. Just a limited number of articles are available in the literature dealing with the chemical composition of the C. esculentus L. plant, with some of them focused on the edible tuber (42,43) or related to other Cyperus plants (44), such as Cyperus rotundus (45), Cyperus articulatus (46), or Cyperus papyrus (47). Considering the chemical composition of similar plants, it can be stated that results reported for Cissus populnea stems (48) showed higher values for all the studied parameters than those obtained in this study; while higher protein content (6.1 ± 0.4%) and lower fat content (0.002%) were reported for Cyperus tegetum (49).…”

“…Mondragon et al (52) studied similar plants and residues, such as sisal, hemp and flax fibers, with values ranging between 14.2 ± 0.1 and 20.7 ± 0.4% for NaOH 1% solubility and between 3.2 ± 0.3 and 6.9 ± 0.1% for H 2 O solubility. These differences in chemical composition may be due to the different geographical origin, cultivar, maturity and sample preparation (including drying, extraction, and analysis) (47). Besides, the chemical composition of DP demonstrated that this residue has the potential to be used as a source of carbohydrates, especially α-cellulose, which is a valuable material in several sectors, such as cosmetics or packaging.…”

Tiger nut is highly appreciated in the Mediterranean basin by the large number of nutritional advantages offered by a beverage, called “horchata,” which is directly obtained from the tuber of Cyperus esculentus L. However, the current tiger nut harvesting and processing practices generate a large number of residues, mainly a solid by-product after processing and the plant that remains spread out in the fields. In this work the plant residues have been fully characterized to get a clear picture of the possibilities for its valorization to generate products with high added value. Several analytical techniques have been applied to obtain data to assess the real possibilities of these residues in advanced applications in the food, packaging and nutrition sectors. Results on the compositional and elemental analysis, monosaccharide composition, phenolic concentration, and antioxidant capacity were obtained from the dry powder (DP). The high content of α-cellulose (47.2 ± 1.8%) in DP could open new possibilities for these residues as raw material in the production of cellulose nanoentities. Many essential minerals with nutritional interest (Na, Mg, Ca, Mn, Fe, Cu, and Zn) and free sugars (xylose, arabinose, glucose, and galacturonic acid) were identified in the DP making it an interesting source of valuable nutrients. The total carbohydrate content was 171 ± 31 mg gdm–1. In addition, microwave-assisted extraction (MAE) was used to obtain extracts rich in polyphenolic compounds. A Box–Behnken design (BBD) was used, and the optimal extraction conditions predicted by the model were 80°C, 18 min, ethanol concentration 40% (v/v), and solvent volume 77 mL, showing an extraction yield of 2.27 ± 0.09%, TPC value was 136 ± 3 mgGAE 100 gdm–1 and antioxidant capacity by the ABTS method was 8.41 ± 0.09 μmoltrolox gdm–1. Other assays (FRAP and DPPH) were also tested, confirming the high antioxidant capacity of DP extracts. Some polyphenols were identified and quantified: p-coumaric (7.67 ± 0.16 mg 100 gdm–1), ferulic (4.07 ± 0.01 mg 100 gdm–1), sinapinic (0.50 ± 0.01 mg 100 gdm–1) and cinnamic acids (1.10 ± 0.03 mg 100 gdm–1), 4-hydroxybenzaldehyde (1.28 ± 0.06 mg 100 gdm–1), luteolin (1.03 ± 0.01 mg 100 gdm–1), and naringenin (0.60 ± 0.01 mg 100 gdm–1). It can be concluded that C. esculentus L. residues obtained from the tiger nut harvesting and horchata processing could be an important source of high value compounds with potential uses in different industrial sectors, while limiting the environmental hazards associated with the current agricultural practices.

“…Additionally, ancient civilizations used the pith of papyrus stems to make papyrus sheets, which had been an important writing surface ( Nicholson and Shaw, 2000 ; Bausch et al., 2022 ). But more importantly, papyrus shows a strikingly high biomass productivity rate, with an aerial net primary production reaching up to 136.4 t DM ha -1 yr -1 ( Jones et al., 2018 ; Rosado et al., 2021 ). The high productivity rate, and the fact that the plant also grows throughout the year, make papyrus an interesting source of biomass for the production of chemicals, materials and fuels in the context of a lignocellulosic biorefinery.…”

Papyrus (Cyperus papyrus L.) is a sedge plant with a high rate of biomass productivity that represents an interesting raw material to produce chemicals, materials and fuels, which are currently still obtained from fossil resources, in the context of a lignocellulosic biorefinery. In this work, the content and chemical composition of the lipids present in papyrus stems were thoroughly studied. For this, the papyrus stems were separated into the rind and the pith. The lipid content accounted for 4.1% in the rind and 4.9% in the pith (based on dry matter). The main compounds identified in both parts of the papyrus stem were hydrocarbons, n-fatty acids, 2-hydroxyfatty acids, alcohols, alkylamides, mono- and diglycerides, steroids (sterols, ketones, hydrocarbons, esters and glycosides), tocopherols, tocopherol esters, phytol, phytol esters, alkyl ferulates, ω-carboxyalkyl ferulates (and their monoglycerides), and acylglycerol glycosides. The rind presented a predominance of n-fatty acids (6790 mg/kg; that represented 28.6% of all identified compounds), steroid compounds (6255 mg/kg; 26.3%), phytol and phytol esters (4985 mg/kg; 21.0%), and isoprenoid hydrocarbons, namely phytadiene and squalene (2660 mg/kg; 11.2%), while the most abundant lipids in the pith were steroids (8600 mg/kg; 44.4% of all identified compounds) and fatty acids (6245 mg/kg; 32.2%). Due to the great diversity and significant abundance of the compounds identified in papyrus, it can be considered as a potential raw material for biorefineries to obtain valuable phytochemicals of interest to various industrial sectors.
