Summary: This study aimed to produce process flavorings using the Maillard reaction by extrusion method with methionine and glucose. A carrier, modified starch, was used to reduce torque during production. Different formulations with varying ratios of methionine, glucose, modified starch, and water were prepared and fed into an extruder. Parameters such as appearance, torque, pH, color, volatile compounds, and sensory evaluation were measured. The extrudate with the highest amount of modified starch (MS45) had the highest L* value of 88.00, increasing to 93.00 after grinding. All formulations showed similar sensory scores in terms of aroma, taste, and solubility, with slight differences in color. The torque varied among the formulations, with MS25, MS35, and MS45 having lower torque than MS5 and MS15. Gas chromatography-mass spectrometry analysis of the extruded flavorings from MS25 revealed the presence of various volatile compounds, including sulfurous and vegetable odor compounds. The successful production of process flavorings using modified starch as a carrier was demonstrated.

Summary: In the modern world, the sustainability of animal and plant protein is being called into question due to the need for arable land and potable water. Finding alternative protein sources for human consumption is urgent, especially in developing countries. Microbial bioconversion of valuable materials into nutritious microbial cells offers a sustainable alternative, known as microbial protein (SCP), which can be used for both human and animal food. Producing SCP not only provides a sustainable protein source but also helps reduce waste disposal problems and production costs. However, addressing challenges such as awareness and regulatory acceptance is crucial for SCP to become a viable alternative.

Summary: The tolerance of microorganisms to toxic compounds generated during biomass pretreatment is a major challenge in the cost-effective production of bio-based products from lignocellulose. The understanding of tolerance mechanisms is limited, making rational engineering difficult. In this study, adaptive laboratory evolution was used to obtain 20 tolerant strains of Bacillus subtilis, capable of utilizing Distiller's Dried Grains with Solubles-derived hydrolysate. These evolved strains showed improved growth and retained heterologous enzyme production using a medium based on 100% hydrolysate, while the starting strains showed minimal growth. Whole-genome resequencing revealed mutations in the global regulator codY in 15 of the 19 sequenced isolates, as well as mutations in genes related to oxidative stress and flagella function. Overall, tolerance adaptive laboratory evolution proved to be valuable for the utilization of lignocellulose.

Summary: In this study, ferulic acid (FA) and p-coumaric acid (pCA) were extracted from rice straw using an aqueous two-phase system (ATPS) based on the cloud point of surfactant/copolymer Pluronic F-127 (PF-127). The extraction process resulted in 75.8% yield for FA and 74.3% yield for pCA at a concentration of 9.4% w/w of PF-127. Furthermore, the extracted FA and pCA were concentrated 2.3 and 2.5-fold, respectively, compared to their original concentrations, resulting in a PF-127 gel containing 0.12% w/w of hydroxycinnamic acids (HAs). This material shows potential for application in the cosmetics industry for high value-added products in rice straw-based biorefineries.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
