METHOD FOR DETERMINING THE SHELF LIFE OF CANNED FISH Russian patent published in 2019 - IPC G01N33/12 

FIELD: food industry.

SUBSTANCE: invention relates to food industry and can be used to determine the shelf life of natural canned fish. For this purpose, natural canned fish is stored at the temperature of 30–55 °C, periodically determining the organoleptic characteristics, acid number of fat and the content of amino-ammonia nitrogen by the point system. Samples of not less than three batches of canned fish of the same name are used, and organoleptic evaluation is carried out after receiving positive results of microbiological tests not less than two cans. On the basis of the obtained results, the estimated shelf life at any storage temperature is calculated by the program "Reserve-forecast", which is adjusted for the reserve ratio by dividing the expected shelf life by 1.15.

EFFECT: invention provides reliable data on calculation of the shelf life of canned fish.
