“…(Table III).-The preservative activity of the parabens increased as the length of the side chain increased. These results agree with previous reports on their effectiveness as preservative or antifungal agents at the pH levels included in this test (6,9,13,21). However, it has been reported that this relationship between chain length and activity does not exist a t pH 6 since methyl and ethyl esters were more active at pH 6 than the propyl and butyl esters (13).…”

“…4). This agrees with the observations that at lower pH values, the effectiveness of sorbate increases (2,3). This is evidenced by the fact that at pH 5.5, three to five times as much sorbate was required to get the same antifungal effects as at pH 4.7.…”

Two strains of Penicillium digitatum and one strain of Penicillium italicum were exposed to various levels of sorbic acid and potassium sorbate, and the MICs were determined. Selected strains of the molds were then repeatedly exposed to subinhibitory levels of the compounds to determine whether increased tolerance might develop. The MIC of sorbic acid (pH 4.75) to P. digitatum was between 0.02 and 0.025%. The MIC of sorbate (pH 5.5) to two strains of P. digitatum and P. italicum was found to be between 0.06 and 0.08%. Increasing levels of sorbate resulted in increasing growth suppression of the molds. Populations of P. digitatum were tested for increased tolerance to sorbic acid, and none was found. Individual molds that started from the same parent colony were examined for increased tolerance to potassium sorbate. Two P. digitatum strains developed no observable increased tolerance, but P. italicum developed a slight increase in tolerance to sorbate. When spores of P. italicum and P. digitatum were exposed to higher levels of sorbate for prolonged times, the fungicidal or fungistatic activity of the inhibitor was dependent upon pH, length of exposure time, level of sorbate, and the mold strain.

“…The MIC in this study of potassium sorbate against test molds ranged between 750 to 1500 ppm at pH 6.0 and 500 -1500 ppm, at pH 5.0 and 5.5. The results indicated that the MIC of potassium sorbate at pH 5.0 was slightly contrary to the observations of [20], who reported that the minimum antimicrobial activity of sorbate was 800 ppm at pH 5.0. However, [21] observed that the MIC of potassium sorbate was in the range between 100 -1000 ppm and was dependent on the pH of the substrate, types and numbers of molds, as well as their environmental factors.…”

Inhibition of spoilage mold of common contaminant of bakery goods in modal agar system by potassium sorbate and calcium propionate in wide range of concentration (0 - 2000 ppm) at different pH (5.5 - 7) was investigated. All Samples were examined daily for mold growth. Results showed that both potassium sorbate and calcium propionate can be used effectively to inhibit mold growth and the effectiveness of these preservatives is enhanced by increasing the concentration and decreasing the pH. The effect of modified atmosphere packaging (MAP) comprised of 60% or 80% CO2 (balance N2) and oxygen absorbents on the growth of mold was also studied on the agar system. The results indicated that mold growth was prevented up to 42 days in packs flushed with 60% or 80% CO2 (balance N2). It was also evident that all samples did not show mold growth for >40 days when packaged in the presence of oxygen scavenger sachet
