Usage

Description

9-Eicosene is an essential oil derived from the flower of the Allium rotundum L. plant, known for its ability to inhibit common bacteria that contribute to the spoilage of processed foods, thereby extending their shelf-life.

Uses

Used in Food Preservation Industry:
9-Eicosene is used as a natural preservative for processed foods to inhibit the growth of common bacteria that cause spoilage and reduce the shelf-life of these products. Its natural antibacterial properties make it a valuable addition to the food industry for maintaining the quality and safety of processed foods.
