SANITIZING EFFECT OF PROPIONIC ACID ON BACTERIOLOGICAL QUALITY OF BEEF
C. Latha and E. Nanu.
The effect of propionic acid ou the initial bacterial load on beef carcasses was studied. Strips of meat removed from beef carcasses were subjected to propionic acid treatment. The bacterial load was assessed at intervals of 1,5,9 and 24h. Total viable count, Coliform conunt and faecal streptococcal count were estimated. Highly significant difference (P<0.01)nl bacterial counts were observed between control and treatments, and between treatments. It is concluded that beef can be stored for 5 hrs. after treatment with one percent propionic acid and for 9 hrs. after treatment with two percent propionic acid at an ambient temperature without altering bacterial count.
