If the alcohol concentration is 0.33～0.5Vol% at the surface of the food, it can almost prevent the mildew completely.
When it is used in the product with high AW (eg: above 0.9), the alcohol will dissolve in the moisture, so the concentration of alcohol cannot rise completely. Because of this reason, the large-capacity alcohol freshness retainer will be chosen, and the cost will be higher.
If the AW of the food is below 0.8, the alcohol freshness retainer with small capacity can work effectively, and also economic
