The Claim
The absence of synergistic inhibition between sorbic acid and tested natural products remains unchanged across glucose concentrations of 2% and 0.1%, as indicated by Fractional Inhibitory Concentration Indices (FICI) ≥ 0.5 in all experimental conditions.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Sorbic acid and natural products do not work together more effectively than expected, regardless of whether the sugar level in the environment is high or low.
See the scientific wording
The absence of synergistic inhibition between sorbic acid and tested natural products was consistent across both high (2%) and low (0.1%) glucose conditions, with Fractional Inhibitory Concentration Indices (FICI) ≥ 0.5 in all cases, suggesting glucose concentration does not alter the lack of synergy.
Sorbic acid and natural products each block yeast growth on their own, but they do not work together better — changing sugar levels does not make them interact differently.
What the research says
1 studyScientists tested if adding natural products to sorbic acid could better stop yeast growth in both sugary and low-sugar environments. No matter how much sugar was present, none of the natural products made sorbic acid work better — the results were the same.
