Sorbic Acid as a Wine Preservative-Its Efficacy and Organoleptic Threshold
Sorbic acid was added to wines in different concentrations to determine its effect on the inhibition of yeasts in semi sweet wines. Sorbic acid proved to be an effective inhibitor of yeast growth when used at a concentration of 200 mgle in conjunction with a concentration of 100 mg S02IC. As the sorbic acid does not kill the yeast cells but only inhibits them it is imperative that the wine shou...
متن کاملThe weak acid preservative sorbic acid inhibits conidial germination and mycelial growth of Aspergillus niger through intracellular acidification.
The growth of the filamentous fungus Aspergillus niger, a common food spoilage organism, is inhibited by the weak acid preservative sorbic acid (trans-trans-2,4-hexadienoic acid). Conidia inoculated at 10(5)/ml of medium showed a sorbic acid MIC of 4.5 mM at pH 4.0, whereas the MIC for the amount of mycelia at 24 h developed from the same spore inoculum was threefold lower. The MIC for conidia ...
متن کاملSorbic acid as a selective agent in cucumber fermentations. II. Effect of sorbic acid on the yeast and lactic acid fermentations in brined cucumbers.
Previous studies (Costilow et al., 1955) demonstrated that the yeasts found to be most prevalent in cucumber fermentations were completely inhibited by 0.01 per cent sorbic acid in an 8 per cent salt (NaCl) medium at pH 4.6. As the pH was increased and/or the salt concentration decreased, more sorbic acid was required for complete inhibition of some of the yeasts tested. Cultures of Pediococcus...
متن کاملEvidence That R-Synuclein Does Not Inhibit Phospholipase D
R-Synuclein (RSyn) is a small cytosolic protein of unknown function, which is highly enriched in the brain. It is genetically linked to Parkinson’s disease (PD) in that missense mutations or multiplication of the gene encoding RSyn causes early onset familial PD. Furthermore, the neuropathological hallmarks of both sporadic and familial PD, Lewy bodies and Lewy neurites, contain insoluble aggre...
