A novel pectin-crosslinked β-cyclodextrin complex for effectively reducing cholesterol content in beef tallow:...

Area of Science:

• Food Chemistry
• Materials Science
• Biotechnology

Background:

• High cholesterol in beef tallow poses health risks.
• Current methods for cholesterol reduction may be insufficient or costly.

Purpose of the Study:

• To develop an efficient method for cholesterol removal from beef tallow.
• To synthesize and characterize a novel pectin-crosslinked beta-cyclodextrin complex.

Main Methods:

• Synthesis of pectin-crosslinked beta-cyclodextrin complex.
• Fourier-transform infrared spectroscopy, proton nuclear magnetic resonance, and X-ray diffraction for characterization.
• Molecular dynamics simulations to understand the interaction with cholesterol.

Main Results:

• The complex successfully removed 74.69% of cholesterol from beef tallow.
• Enhanced thermal stability (Tpeak: 113.59°C) and porous, crumpled morphology were observed.
• Molecular dynamics simulations confirmed non-covalent hydrogen bonding driving cholesterol removal.

Conclusions:

• The pectin-crosslinked beta-cyclodextrin complex is a promising agent for cholesterol removal from beef tallow.
• The study elucidates the molecular mechanism and structure-activity relationship for cholesterol adsorption.
