title Freshness Checker

Any part of any kind of fish, frozen or raw, can be measured scientifically.

Freshness Checker

These devices were developed by Professor Emeritus Minoru Sato at the Marine Biochemistry Laboratory of Tohoku University Faculty of Agriculture.

As time goes by, fish and meat deteriorate, their composition changes and the taste declines. The accumulation of certain chemicals can cause severe reactions such as food poisoning or allergy. Freshness Checker makes use of changes occurring in the cells of meat tissues, where Adenosine triphosphate (ATP, the main energy transport molecule within cells) is converted to Inosine (HxR) and then Hypoxanthine (Hx) as the cells deteriorate.
UV radiation is used to visualize the presence of the breakdown products of ATP, allowing them to be identified, photographed and measured accurately within a short time.

The K value is determined by the following formula

The K value is determined by the following formula

The Freshness Checker is based on electrophoresis, which separates various components present in healthy animal tissues, such as ATP and ADP, and products of decay, such as HxR and Hx.

Can be used for meat products as well as fish.
