The Cybertongue® Company

Do you have concerns about the shelf-life of UHT-milk?

We can help.

Failures in meeting shelf-life expectations for UHT-milk due to proteases is a major concern and regular problem for UHT processors globally.

PPB TechnologyTM has developed the first practical solution to detect problems associated with proteases. We can now measure problem levels of protease in raw milk supply as an external testing service .

CYBERTONGUE® sources ultrasensitive and specific biosensors from nature and combines them with cutting edge microfluidic and photonic technologies, delivering laboratory quality results in minutes.


Our vision is to provide customers with the means to generate their own laboratory quality test results on the spot within minutes. This is revolutionary for food processing, farm production, pharmaceutical and cosmetic production, animal health, environmental testing, and food safety industries.

Developed in partnership with the CSIRO, CYBERTONGUE® has the potential to make this vision a reality. Register your interest today.

How It Works

CYBERTONGUE® can measure a range of low-level components in complex liquid samples. Current applications include residual lactose in “lactose free” milk and proteases in raw milk supply. This can answer in minutes questions that, in some cases, would take ten days to answer using current testing methods.

We can test raw milk or finished product samples for protease levels and/or lactose levels in-house. After receiving samples, we will send you the analysis results within one week and we will explain what those results mean.

The technology is protected by several granted and pending patents, and is currently being expanded to detect a range of other targets including: allergens, hormones, toxins, antibiotics and biomarkers of animal and human diseases.

We tailor solutions to inform real-time decision making across:

Food Processing

Safety & compliance, shelf-life, provenance, nutritional value


Real time tests for productivity, quality, profitability and health

Other Manufacturing Industries

Precise, real time analysis for process control and optimisation

Human Health

Point of care tests for diagnosis and patient stratification
