“…The endogenous metabolites of biomass are composed of primary and secondary metabolites. In the different biomass, the major constituents are cellulose, hemicellulose, lignin, which can be applied to prepare various valueadded products and bio-materials (Sun et al, 2019;Zhou et al, 2019;Chen et al, 2020;Geng et al, 2020;Chen et al, 2021;Liu et al, 2021;Luo et al, 2021). Apart from these constituents, there is existed various minor constituents, such as flavonoids and polyphenols (Si et al, 2009;Gironi and Piemonte, 2011;Quideau et al, 2011;Goodman, 2020).…”

Biomass polyphenols are bio-active macromolecules with distinct chemical structures in a variety of biomass. In recent years, the study of biomass polyphenols and their application in food and medicine fields has become a research hotspot, which predominantly focuses on the preparation, purification, structural identifications, and measurements of biological activities. Many studies describe methodologies for extraction and application of polyphenols, but comprehensive work to review its physiological activities like drugs and health products are lacking. This paper comprehensively unlocks the bioactivities of antioxidant, antibacterial, antitumor, anticancer, neuroprotection, control of blood sugar, regulation of blood fat, and promotion of gastrointestinal health functions of polyphenols from different biomass sources. This review will serve as an illuminating resource for the global scientific community, especially for those who are actively working to promote the advances of the polyphenols research field.

“…All of lignocellulosic biomass is composed of the cellulose, hemicellulose, and lignin with different proportions ( Hu et al, 2021 ; Zhang et al, 2021 ; Zhao et al, 2021b ). Currently, the application of cellulose and hemicellulose have been much investigated and converted into energy chemicals in industry ( Huang et al, 2016a ; Chen et al, 2018 ; Lai et al, 2019 ; Luo et al, 2021 ). However, lignin, the major phenolic polymers in biomass, remains underutilized in biorefining, which is required to explore the potential applications in theory ( Liu et al, 2021a ; Liu et al, 2021b ; Huang et al, 2022 ).…”

Ball milling technology is the classical technology to isolate representative lignin in the cell wall of biomass for further investigation. In this work, different ball milling times were carried out on hardwood (poplar sawdust), softwood (larch sawdust), and gramineous material (bamboo residues) to understand the optimum condition to isolate the representative milled wood lignin (MWL) in these different biomass species. Results showed that prolonging ball milling time from 3 to 7 h obviously increased the isolation yields of MWL in bamboo residues (from 39.2% to 53.9%) and poplar sawdust (from 15.5% to 35.6%), while only a slight increase was found for the MWL yield of larch sawdust (from 23.4% to 25.8%). Importantly, the lignin substructure of ß-O-4 in the MWL samples from different biomasses can be a little degraded with the increasing ball milling time, resulting in the prepared MWL with lower molecular weight and higher content of hydroxyl groups. Based on the isolation yield and structure features, milling time with 3 and 7 h were sufficient to isolate the representative lignin (with yield over 30%) in the cell wall of bamboo residues and poplar sawdust, respectively, while more than 7 h should be carried out to isolate the representative lignin in larch sawdust.

“…Currently, lignocellulosic biomass plays an important role in the energy, chemical, and material fields because of its zero carbon dioxide emissions, high content, and renewable properties (Luo et al, 2021;Zhu et al, 2020). Cellulose is the main component of the lignocellulosic biomass (Bian et al, 2019).…”

The mercerization of fiber is an important method for the high-value utilization of cellulose. In this study, the bagasse fiber was mercerized by freeze–thaw-assisted alkali treatment (FT/AT). The effects of freezing temperature, freezing time, alkali concentration, and thawing temperature on cellulose and hemicellulose removal were studied. The optimal freezing temperature was −40°C, freezing time was 8.0 h, alkali concentration was 5.0%, and thawing temperature was 30°C. The highest removal rate of hemicellulose was 75.64%. It was 5.80% higher than that of alkali treatment (AT). The alkaline degradation of cellulose was inhibited. The penetration of alkaline solution to fiber was promoted by the assistance of freeze-thaw pretreatment. The effective alkali concentration (5.0%) of cellulose I completely transformed into cellulose II decreased by 66.67% compared with traditional alkaline mercerization (15.0%). The high-efficiency mercerization of fiber was achieved by FT/AT. It provides theoretical support for promoting the high-value utilization of lignocellulosic biomass.
