Chemical properties:
Potassium sorbate appears as white to pale yellow flaky crystals and crystalline powder or granular. Potassium sorbate is odorless or slightly smelly. Long-term storage in the air is easy to absorb moisture and oxidative decomposition as well as coloring. Potassium sorbate has a strong effect on inhibiting spoilage and mold, and because of its lower toxicity than other preservatives, it has become the world's most important preservatives.
In acidic conditions, Potassium sorbate can give full effect of anti-corrosion while the effect is the lowest in neutral condition.
Uses:
Potassium sorbate can be used as preservatives and anti-mildew agent in the food industry.
