Summary
Nanocellulose coated with free fatty acids (NCCFFAs) effectively adsorb fumonisin B1 (FB1). NCCFFAs significantly reduce FB1 toxicity, offering a novel solution for food safety.
Area of Science:
- Materials Science
- Food Science
- Toxicology
Background:
- Fumonisin B1 (FB1) is a mycotoxin with high toxicity.
- Current methods for FB1 removal are limited.
- Nanocellulose and free fatty acids (FFAs) show potential for mycotoxin adsorption.
Purpose of the Study:
- To synthesize and characterize nanocellulose coated with free fatty acids (NCCFFAs).
- To evaluate the adsorption capacity of NCCFFAs for FB1.
- To assess the biological properties and FB1-neutralizing effects of NCCFFAs.
Main Methods:
- Nanocellulose synthesized via acid hydrolysis.
- Nanocellulose coated with lauric acid, alpha linoleic acid, oleic acid, and palmitic acid.
- Adsorption experiments with varying NCCFFA concentrations and incubation times.
- Cell viability assays using mouse liver cells exposed to NCCFFAs, FFAs, and FB1.
Main Results:
- Adsorption of FB1 by NCCFFAs increased with incubation time and NCCFFA concentration.
- NCCFFAs and FFAs exhibited low toxicity to mouse liver cells.
- FB1 demonstrated high toxicity, which was significantly reduced when co-incubated with FFAs or NCCFFAs.
Conclusions:
- NCCFFAs are effective adsorbents for FB1.
- NCCFFAs demonstrate a significant reduction in FB1 toxicity.
- NCCFFAs represent a promising novel adsorbent for FB1 removal in foodstuffs.

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to...

Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...
