Quality Control

Our Protein Hydrolyzates, Yeast are manufactured under a rigorous quality management system. Each batch is tested to ensure it meets stringent specifications for key parameters including total nitrogen, amino acid profile, microbiological purity, and solubility. Certificates of Analysis (COA) documenting these results are available upon request. Production can be aligned with relevant standards for food, pharmaceutical, or industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
