Arabinoxylans (AX) gels at 4% (w/v) wereprepared using laccase (LAX gels) or peroxidase (PAXgels), and their cross-linking, rheological, structural, andspectroscopic characteristics were investigated. LAX gelspresented lower amount of 5,50-diferulic acid (11%),smaller mesh size (128 nm), and higher hardness (37 N)and elasticity (430 Pa) than the PAX gels (28%, 197 nm,7 N, and 120 Pa, respectively). Microscopy of the LAXgels showed linked strands, while the system was lessconnected in the PAX gels. The Raman band at 2895 cm-1of the LAX and PAX gels was less intense, indicatingenhanced hydrogen bonding compared to that of AX. Thisdecrease was less dramatic for the PAX gels. The greatercontent of 5,50-diferulic acid in PAX gels could favorintrachain bonds, affecting their rheological, structural, andspectroscopic characteristics. Laccase may be a betteroption than peroxidase for AX gelation intended for foodand biotechnological applications.

Obesity is an abnormal or excessive accumulation of fat in the body that exacerbates metabolic and inflammatory processes, and impairs the health of afflicted individuals. β-caryophyllene is a natural sesquiterpene that is a dietary cannabinoid with anti-inflammatory properties and potential activity against metabolic diseases. In the present study, we evaluated the effect of β-caryophyllene on C57BL/6 mice using a diet-induced obesity model. Male mice were randomly assigned to the following groups over a 16-week period: (1) standard diet as lean control, (2) high-fat diet (HFD) as obese control, and (3) HFD + β-caryophyllene with β-caryophyllene at 50 mg/kg. Treatment with β-caryophyllene improved various metabolic parameters including increased total body weight, fasting glucose levels, oral-glucose tolerance, insulin tolerance, fasting triglycerides, adipocyte hypertrophy, and liver macrovesicular steatosis. β-caryophyllene also modulated the levels and expression of immune response factors including adiponectin, leptin, insulin, interleukin-6, tumor necrosis factor-a, and Toll-like receptor-4. Our data indicate that chronic supplementation with β-caryophyllene can improve relevant metabolic and immunological processes in obese mice. This protocol was approved by the Institutional Committee for Care and Use of Laboratory Animals from the University of Guadalajara with protocol code CUCEI/CINV/CICUAL-01/2022.
