The detection and control of water activity are very important for the development and production of probiotic powder and probiotic preparations. In order to reduce and minimize the risk of microbial contamination and maintain the stability of probiotics, their water activity must be controlled within a relatively low range, such as some probiotics with activity within 0.25, and some probiotics with activity within 0.2 or even lower.

The instability of temperature and humidity, especially in summer, can directly affect the stability, activity, shelf life, and application of packaging materials of probiotics. Reasonably controlling the water activity value of probiotics within a certain range will be more helpful in inhibiting the growth of harmful microorganisms, while protecting the activity of probiotics and ensuring the quality of products during research and development, production, transportation, and storage.

The GYAL high-end probiotic water activity analyzer developed by Shenzhen Guanya can detect the water activity of different types of samples (liquid, powder, particles), and can be operated through online interactive control to automatically generate detection reports. It can be customized according to user needs, including activity calibration points, activity calibration points, testing methods, testing channels, etc;

GYAL high-end probiotic water activity analyzer has high measurement accuracy, short time, easy operation, no need for auxiliary equipment. Enter the sample name, follow the testing instructions, and read various effective data in real time during the testing process. The equipment has no vulnerable parts.

Adopting a 7-inch high-resolution LCD screen and a full touch operation mode, the instrument displays real-time data changes in the sample, as well as real-time changes in the test curve (screen) of the sample. The entire testing process is fully automated, and after analysis is completed, the instrument screen automatically locks the final data and saves it automatically.
