Megjegyzések:	Poniol (Flacourtia jangomas) has beneficial health effects due to its high polyphenolic and good antioxidant activity content. This study aimed to encapsulate the Poniol fruit ethanolic extract to the sucrose matrix using the co-crystallization process and analyze the physicochemical properties of the co-crystalized product. The physicochemical property characterization of the sucrose co-crystallized with the Poniol extract (CC-PE) and the recrystallized sucrose (RC) samples was carried out through analyzing the total phenolic content (TPC), antioxidant activity, loading capacity, entrapment yield, bulk and traped densities, hygroscopicity, solubilization time, flowability, DSC, XRD, FTIR, and SEM. The result revealed that the CC-PE product had a good entrapment yield (76.38%) and could retain the TPC (29.25 mg GAE/100 g) and antioxidant properties (65.10%) even after the co-crystallization process. Compared to the RC sample, the results also showed that the CC-PE had relatively higher flowability and bulk density, lower hygroscopicity, and solubilization time, which are desirable properties for a powder product. The SEM analysis showed that the CC-PE sample has cavities or pores in the sucrose cubic crystals, which proposed that the entrapment was better. The XRD, DSC, and FTIR analyses also showed no changes in the sucrose crystal structure, thermal properties, and functional group bonding structure, respectively. From the results, we can conclude that co-crystallization increased sucrose's functional properties, and the co-crystallized product can be used as a carrier for phytochemical compounds. The CC-PE product with improved properties can also be utilized to develop nutraceuticals, functional foods, and pharmaceuticals.

Megjegyzések:	The study focused on utilizing lemon grass straw to generate cellulose through the process of delignification, which involves the removal of hemicelluloses, followed by bleaching. The study involves the microwave-assisted alkali extraction, followed by characterizing the extracted material. At microwave power of 540 W using 8 % NaOH for 3 min for lignin removal and 540 W for 2 min for bleaching showed the maximum yield of 37.46 %. Fourier transform infrared spectroscopy is employed to analyze the physical properties of extracted cellulose, namely the hydroxyl (OH), carbonyl (C=O), C-H bonds, C-O and C-C bonds, and glycosidic linkage (C-O-C) within the cellulose polymer chain. The extracted cellulose exhibited excellent thermal stability, as indicated by its high breakdown temperature. The X-ray diffraction (XRD) analysis revealed prominent peaks at 14.8?, 16.5?, and 22.5?, demonstrating the presence of crystalline cellulose. The crystallinity index value of 70.02 % further confirmed the crystalline nature of the extracted cellulose.
