To study the relationship between the number of hydroxyl groups of polyols and the plasticizing effect, the effects of different polyols including ethylene glycol, glycerol, erythritol, xylitol and sorbitol on the structure and properties of corn starch straws were analyzed and compared. The results showed that the addition of plasticizer significantly improved the performance of starch straws, which greatly improved the mechanical properties, water absorption rate (WAR) and thermal stability. However, there was no linear relationship between the plasticizing effect on starch straws and the number of hydroxyl groups in plasticizers. Fourier transform infrared (FTIR) results showed that erythritol formed the strongest intermolecular interaction with starch. Starch straws with erythritol (S-ERY) had the highest bending force (F = 25.78 N) and the lowest WAR. Starch straws with glycerol (S-GLY) showed the lowest relative crystallinity (RC = 12.87 %) and the highest temperature of the maximum degradation (T = 302.1 °C). In addition, after storing for 180 days, S-GLY showed higher modulus of elasticity in bending (E = 4.26 N/cm) and a uniform surface.

Densification of biomass through pelletizing offers a promising approach to producing clean biofuels from renewable resources. This study, which investigates the impact of additive blends on wheat straw pellet making and upgrading the physiochemical properties, has revealed exciting possibilities. Five additives, including sawdust (SD), bentonite clay (BC), corn starch (S), crude glycerol (CG), and biochar (BioC), were chosen for this study.

The aim of this study was to determine the effect of milk thistle (Silybum marianum L., SM) oil supplementation on proinflammatory cytokines, acute phase proteins, rumen metagenomic profile, rumen fluid variables and performance during the milk feeding period of Holstein calves. In the present study, 24 calves that consumed quality and sufficient amount of colostrum (≥50 mg/ml IgG) after birth were divided into three groups, with 8 animals in each group (4 males + 4 females).

This study aimed to assess the effects of different ratios of water and glycerol on the physicochemical properties of starch-based straws (SBS) and explore their plasticising mechanism. X-ray diffraction analysis revealed that the V-type complex formation was influenced by adjusting the ratio of glycerol and water. The extruded samples exhibited lower water content (4.
