VEMO 99’s laboratories are staffed with trained chemists and technicians with years of industry knowledge and expertise. Our labs are equipped with high-tech instrumentation, allowing for accurate analysis and testing. Thus, we can provide enzyme activity analysis for a broad range of products, markets and industries.

Enzymes are crucial additives to both animal feeds and human dietary supplements. Their use as digestion and metabolic supporters is becoming highly common in a wide variety of application fields.

Since enzymes are bio active molecules, they are highly sensitive to manufacturing processes, like temperature, pelleting, moisture, etc. Thus, it is important to measure the real enzyme activity in both raw materials and finished products. In addition, since enzymes are biological products, they may reduce their activity with time and storage conditions, making it crucial to develop standardized methods for their analysis and validation. It is also important to ensure that enzyme activity analysis is conducted according to the optimal working conditions for each product, like pH, temperature, co-factors, substrates, etc.

With more than 20 years of experience in the design and manufacturing of active enzymes, our team has broad experience with a number of different enzyme activity assays, providing for the high quality of VEMO feed and food enzymes. Thus, we transfer our professional knowledge into assisting you to meet your R&D and business goals. VEMO scientists are confident in providing the comprehensive services for enzyme research. We offer versatile testing methods of measuring the enzyme activity and many enzymes can be assayed in custom ways, upon your request.
