Potassium sorbate
Based on 1 Customer Validation
Potassium sorbate (Sorbic acid potassium) is an antibacterial preservative effective against most molds, yeasts, and some bacterial species. Potassium sorbate inhibits microbial growth. Potassium sorbate suppresses the activity of intestinal microorganisms in zebrafish, alters the composition of intestinal flora, and reduces the levels of intestinal immune biomarkers, including IgG, IL-1β, and TNF-α. Potassium sorbate can be used in research on the prevention and treatment of mold, yeast, and bacterial infections.

Biological Activity
Potassium sorbate (0.05%-0.1%) extends the shelf life of cottage cheese, inhibits the growth of Penicillium frequentans and other spoilage microorganisms, suppresses spoilage bacteria in cottage cheese as well as molds in unsalted butter and grains, and prolongs the safe storage period of grains[1].
Potassium sorbate (0.02%-0.04%) inhibits the growth of molds in ham and sausage, as well as the growth of Aspergillus versicolor, inhibits the growth of Alternaria solani, Penicillium citrinum and Aspergillus niger, with minimum inhibitory concentrations of 0.02%, 0.08% and 0.08%, respectively[1].
Potassium sorbate (0.05-0.15%) delays or prevents spore germination and growth initiation of Aspergillus parasiticus and Aspergillus flavus strains, slows their hyphal growth, inhibits the growth of Aspergillus sulphureus and Penicillium viridicatum as well as their ability to produce ochratoxin A, and reduces or even blocks the production of aflatoxin B1 by Aspergillus parasiticus and Aspergillus flavus[1].
Potassium sorbate (0.05%) inhibits the growth of Zygosaccharomyces rouxii, Saccharomyces bisporus, Saccharomyces acidifaciens and Saccharomyces pastorianus, and is used in combination with acids[1].
Incorporation of potassium sorbate (≥15%) into sweet potato starch films significantly inhibits the growth of E. coli, but exerts no inhibitory effect on S. aureus[3].

Administration:aqueous exposure; daily water replacement; 14 days
-
Result:Decreased levels of intestinal IgG, IL-1β, and TNF-α. Altered core gut microbiota development, with Pelomonas becoming the most abundant genus (accounting for 32.77% of gut microbiota), while Reyranella and Sphingomonas decreased, and Rhizobacter increased. Decreased relative abundance of transcription, energy metabolism, and cancer pathways. Significantly reduced the gut microbiota activity index (AIM).
