METHOD FOR MEAT SORTING INTO QUALITY GROUPS (PSE, NOR AND DFD)

摘要

FIELD: food industry.;SUBSTANCE: invention is intended for beef evaluation and classification, in terms of quality, into the following groups: PSE, DFD and NOR during slaughter animals lifetime. One measures the difference of electric conductivity in Tien-Fu BAP with live animals. When the difference of potentials in BAP Tien-Fu is less than 5 mcA, meat is classified as NOR. When the difference is more than 5 mcA, pH is determined in the rib eye between the eighth and twelfth vertebrae after 45 minutes after slaughtering. When pH is lower than 5.7, meat is categorised as PSE, when pH is higher than 6.2 - as DFD.;EFFECT: proposed method usage allows to perform quickly and accurately meat quality evaluation with raw material division into the following quality groups: PSE, DFD and NOR.;1 tbl, 1 ex, 5 cl
