Most spices such as chili, pepper, cumin, or others are heavily contaminated with microorganisms. Many sterilization processes affect product characteristics such as taste, smell, or color. Since these are important quality features and selling points, effective and gentle sterilization is crucial to establishing a successful product. To help this effort, AVA has developed automatic plants that guarantee 5-log reduction of microbiological contamination. The plants work with dynamic pressure sterilization, giving you a sterilization result free of color or flavor loss. In addition to quality aspects, our method provides a precisely controllable and particularly short sterilization process.
