How to Use Citric Acid as a Preservative

Use 1 tsp citric acid per qt of water or juice when canning produce to help preserve the final product Add 1 tsp citric acid per qt of rinse and soak water when sprouting seeds until ready to consume Use 1 and 1/2 oz per 100 lbs of meat when preserving meat such as jerky

sorbic acid [sorbik] an agent that inhibits growth of yeasts and molds and is used as an antimicrobial preservative sorbic acid (sōr'bik as'id) A preservative obtained from berries of the rowan/mountain ash Sorbus aucuparia (family Rosaceae) or prepared synthetically it inhibits growth of yeast and mold and is nearly nontoxic to humans

By my calculations you have about 570ppm of sorbic acid in your Riesling 1 tsp of Ksorbate weighs 2 9g so that would be 2 9 g/gal or 2900 mg/gal 3 78L to the gal so thats about 766mg/L of KSorbate KSorbate contains about 74% sorbic acid on a molecular weight basis so divide that 766 mg/L by 1 35 to find out the ppm of sorbic acid ~568 ppm

Sorbic acid is used as a preservative (mold and yeast inhibitor) and as a humectant (glycerine replacement) This is a white powder made from mountain ash berries but can also be synthetic Produces a velvety feel when rubbed on the skin but can be sticky in large amounts

14-11-2003At low pH acetic acid (pK 4 75) sorbic acid (pK 4 76) and benzoic acid (pK 4 19) exist substantially in the undissociated state In this form these molecules readily cross the cell membrane However once in the cytosol where the pH is kept at 6 to 7 the acid

21-9-2004If not try it Almost ever organic acid can be successfully retained on a reversed phase column if the carbon load is high enough and the column can stand water For this reason I like the ES Industries Aquasep column but any RP column will retain benzoic and sorbic acids 2 I didn't say to use a phosphate salt Use 0 15% phosphoric acid

For use with a nozzle applicator: flush the affected eye(s) as needed control the rate of flow of solution by pressure on the bottle When using an eye cup: rinse the cup with Eye Wash immediately before each use avoid contamination of the rim and inside surfaces of the cup fill the cup half full with Eye Wash Solution and apply the cup to the affected eye(s) pressing tightly to prevent
