JAKARTA - Technological advances are increasingly making it easier for many things, including for the development of food and beverages. Most recently, a technology that functions to detect milk freshness is launched.

The technology is called VibMilk, which was created by a research team from Computer Science and UNSW Engineering. Launching Oddity Central, on Tuesday, November 19, 2024, VibMilk is a new sensor on smartphones or smartphones that can check the freshness of milk without opening the packaging.

The researchers rely on vibration motors and inertial measurement units (IMU) on smartphones to check the freshness of the milk. VibMilk is expected to reduce 20 percent of the waste of dairy products that are currently often thrown away, even though they are still suitable for consumption.

You can smell or feel whether milk is stale, but to do that you have to open the packaging. Non-invasive vibMilk, which means you can test the freshness of the milk without breaking the seal," said Professor Wen Hu of UNSW.

VibMilk allows testing the freshness of the milk without opening its packaging easily and without expensive or complicated tools. This sensor is also easy to adopt en masse, as it uses a built-in vibrating motor from a smartphone.

Before creating this technology, the researchers had already analyzed how stale milk occurs. Staple milk occurs due to an increase in bacteria.

This increase in bacteria causes an increase in lactic levels and a decrease in glucose levels. When milk is stale, its physical properties change to such as density, viscosity, and surface stress.

All these conditions provide different responses to vibrational signals. VibMilk can capture the response to the vibration produced by a smartphone when passing through milk.

Testing on four common smartphones shows that VibMilk can predict pH milk with an average accuracy of 98.35 percent and achieve 100 percent accuracy to show fresh milk," UNSW said in an official website.
