Production of chitosan-based composite film reinforced with lignin-rich lignocellulose nanofibers from rice husk Hye Jee Kang, Yeon Ju Lee, Jin Kyoung Lee, Irnia Nurika, Sri Suhartini, Deokyeong Choe, Dong Hyun Kim, Hoon Choi, Natasha P. Murphy, Ho Yong Kim, Young Hoon Jung Journal of Bioresources and Bioproducts, 2024 Lignocellulosic nanofibers (LCNFs), implying lignin-containing cellulose fibers, maintain the properties of both lignin and cellulose, which are hydrophobic and hydrophilic, respectively. The presence of hydrophobic lignin in LCNFs is expected to be an economical and attractive option that can improve the thermal and mechanical properties of polymers. Thus, this study was conducted to produce lignin-rich LCNFs from sugar-rich waste obtained from rice husks after acidic pretreatment. The LCNFs were produced from the lignin-rich solid fractions obtained after pretreatment and enzymatic hydrolysis, which were then incorporated as an additive into a chitosan-based film. The variations in lignin content in the range of approximately 50.6%–66.8% in differently obtained LCNFs gave significantly different optical strengths and mechanical properties. These controllable processes may allow for customized film formation. Additionally, the glucose-rich liquid fractions obtained after pretreatment and enzymatic hydrolysis were used as a substrate for ethanol fermentation to achieve total utilization of rice husk biomass waste. In conclusion, the lignin-rich biomass fraction holds promise as a suitable material for chitosan-LCNF film and has the potential to increase the economic feasibility of the biomaterial industry.
Characterization of Yeast Protein Hydrolysate for Potential Application as a Feed Additive Ju Hyun Min, Yeon Ju Lee, Hye Jee Kang, Na Rae Moon, Yong Kuk Park, Seon-Tea Joo, Young Hoon Jung Food Science of Animal Resources, 2024 Yeast protein can be a nutritionally suitable auxiliary protein source in livestock food. The breakdown of proteins and thereby generating high-quality peptide, typically provides nutritional benefits. Enzyme hydrolysis has been effectively uesed to generate peptides; however, studies on the potential applications of different types of enzymes to produce yeast protein hydrolysates remain limited. This study investigated the effects of endo- (alcalase and neutrase) and exotype (flavourzyme and prozyme 2000P) enzyme treatments on yeast protein. Endotype enzymes facilitate a higher hydrolysis efficiency in yeast proteins than exotype enzymes. The highest degree of hydrolysis was observed for the protein treated with neutrase, which was followed by alcalase, prozyme 2000P, and flavourzyme. Furthermore, endotype enzyme treated proteins exhibited higher solubility than their exotype counterparts. Notably, the more uniform particle size distribution was observed in endotype treated yeast protein. Moreover, compared with the original yeast protein, the enzymatic protein hydrolysates possessed a higher content of β-sheets structures, indicating their higher structural stability. Regardless of enzyme type, enzyme treated protein possessed a higher total free amino acid content including essential amino acids. Therefore, this study provides significant insights into the production of protein hydrolysates as an alternative protein material.
Antioxidant Properties of Kombucha Made with Tartary Buckwheat Tea and Burdock Tea Yeon Ju Lee, Hye Jee Kang, Su Hyung Yi, Young Hoon Jung Preventive Nutrition and Food Science, 2023 Kombucha is a beverage fermented by SCOBY, which is a symbiotic culture of bacteria and yeast. Recently, kombucha has received significant attention due to its health benefits, which include antioxidant and anti-obesity effects. In this study, we investigated the characteristics of kombucha made with Tartary buckwheat and burdock, both known for their high polyphenols content. First, the total polyphenol content and antioxidant activity were measured by 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging assays, which revealed a polyphenol content of 180 ug/mL in Tartary buckwheat kombucha and a high radical scavenging ability of over 90% in both kombucha preparations. Analysis of the changes in the organic acid content during fermentation revealed increases in various organic acid contents, such as glucuronic acid, lactic acid, and acetic acid. Glucuronic acid, especially, which has many functional properties in health, was found to be produced at a concentration of 4.03 g/L in Tartary buckwheat kombucha. Pancreatic lipase inhibitory ability analysis revealed inhibitory effects of 40.47% and 57.68% for Tartary buckwheat and burdock kombucha, respectively. The results of this study confirmed the antioxidant and anti-obesity effects of kombucha made from Tartary buckwheat and burdock, indicating the potential value of these ingredients as functional kombucha ingredients.
Development of a 3D-printable matrix using cellulose microfibrils/guar gum-based hydrogels and its post-printing antioxidant activity Olajide Emmanuel Adedeji, Ju Hyun Min, Gi Eon Park, Hye Jee Kang, Ji-Young Choi, Mariam Omowunmi Aminu, Ocheme Boniface Ocheme, Seon-Tea Joo, Kwang-Deog Moon, Young Hoon Jung International Journal of Bioprinting, 2023 A biomaterial ink suitable for three-dimensional (3D) printing was developed using cellulose microfibrils (CMFs, 1% w/v) and guar gum (1–7 g/100 mL CMFs), and the post-printing stability and antioxidant functionality of the borax-treated construct were investigated. Rheological analysis, Fourier transform infrared spectrometry, X-ray diffractometry, and scanning electron microscopy revealed the suitability of the two polymers to form an interpenetrating composite hydrogel that would facilitate printability. The produced composite hydrogel showed good structural, morphological, thermal, and textural properties. CMFs with 5% guar gum showing optimal surface properties and rheological properties were printed with the least dimensional errors at 50% infill density, 10 mm/s printing speed, 0.8 mm nozzle diameter, and 0.5 mm layer height. The treatment with borax showed good shape fidelity during 12 h storage. The treated construct also showed considerably increased mechanical properties and antioxidant activities in comparison with the untreated construct. A stable 3D construct suitable for a variety of applications could be produced using CMFs and guar gum-based ink.
