Low-salt brining and storage
Sodium chloride concentrations of 5–8% during fermentation and 10–15% during subsequent storage of cucumbers have been used to ensure against enzymatic softening. The addition of calcium ions in the form of calcium chloride (0.20–0.35%) has been found to allow fermentation and storage at lower salt concentrations. Sodium chloride usage can be reduced because of added protection against softening due to calcium ions. Potassium sorbate is often added to control scum growth, especially in warmer climates. This practice is for pickles that will be used in less than 1 year. Long-term storage is not recommended.
