Method for determining expected shelf life of Seafood

摘要

The present invention provides a method of determining the expected shelf life of seafood. The method comprises a step of placing a test strip against a piece of seafood, wherein the test strip includes an indicating pad having a pH indicator that is configured to change color in the presence of ammonia. The method further comprises a step of ascertaining concentration on a parts per million level of ammonia by comparing the color of the pH indicator to a comparative chart, wherein the comparative chart includes a gradient of color intensity that indicates the concentration on a parts per million level of ammonia. Furthermore, the method comprises a step of referencing a booklet having a plurality of charts to cross reference the concentration of ammonia detected by the test strip with the storage temperature to determine an expected shelf life for a piece of seafood.

1. A method of determining expected shelf life of seafood, comprising the steps of:
placing a test strip against a piece of seafood; wherein said test strip is adapted to change color in the presence of ammonia; comparing the color of said test strip to a comparative chart that indicates the concentration of ammonia corresponding to a particular color; wherein said comparative chart includes a gradient of color intensity that indicates said concentrations on a parts per million level of ammonia; determining storage temperature of said piece of seafood; referencing a booklet having a plurality of charts to cross reference the concentration of ammonia detected by said test strip with the storage temperature to determine an expected shelf life; wherein each said chart is applicable to a certain type of seafood, which calculates an expected shelf life for each said type of seafood.
