Sorbic acid is an antibacterial preservative effective against most molds, yeasts, and some bacterial species. Sorbic acid inhibits microbial growth. Sorbic acid 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. Sorbic acid can be used in research on the prevention and treatment of mold, yeast, and bacterial infections.

Description

Sorbic acid is an antibacterial preservative effective against most molds, yeasts, and some bacterial species. Sorbic acid inhibits microbial growth. Sorbic acid 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. Sorbic acid can be used in research on the prevention and treatment of mold, yeast, and bacterial infections[1][2][3].

In Vitro

Sorbic acid (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].
Sorbic acid (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].
Sorbic acid (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].
Sorbic acid (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 Sorbic acid (≥15%) into sweet potato starch films significantly inhibits the growth of E. coli, but exerts no inhibitory effect on S. aureus[3].

In Vivo

Exposure to Sorbic acid (0.1-1 g/L; aqueous exposure; daily water replacement; 14 days) inhibits intestinal microbial activity, alters intestinal flora composition, and reduces the levels of intestinal immune biomarkers, including IgG, IL-1β, and TNF-α[2].

Animal Model: Danio rerio (4-month-old adults)[2]
Dosage: 0.1 g/L; 1 g/L
Administration: aqueous exposure; daily water replacement; 14 days

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).

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (22.30 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (22.30 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
