Measuring the pH of Sushi Rice

Sushi rice needs to be kept warm (about 90°F) for best results when rolling sushi. However, this can create food safety risks which has caused health departments to crack down on practices around the handling of sushi rice, which is often held for up to several hours in the temperature "danger zone".

Most municipalities require that the pH of the sushi rice is maintained below 4.6. The procedures around this standard vary from a full Hazard Analysis Critical Control Point (HACCP) plan for sushi through testing by the health department. Fortunately, the pH can be controlled with rice vinegar, a traditional ingredient used in sushi rice.

A number of our customers are required to maintain a record of hold times and pH levels. These pH meters are some of their favorites!

HALO Bluetooth® Electrode

The HALO probe lets you turn your smartphone or tablet into a professional grade meter using the free Hanna Lab app.

The Hanna Lab app provides a display of the current pH measurement, solution temperature and mV reading, as well as a graphical plot or tabulated record of measured data over time.

The app also features:

• Built-in help
• Easy probe calibration
• Manual or interval data logging for HAACP record keeping
• Data sharing
• Alarms when the readings are outside user-defined limits

The HALO probe’s Bluetooth Smart technology offers many advantages in wireless measurement convenience.

The Foodcare pH and temperature electrode itself is made of chemically resistant PVDF body. This electrode has a unique open junction design that resists clogging and the probe’s conical tip makes it ideal for pH measurements in sushi rice.
