Antiseptic Effect of Three Organic Acids on Pork

Antiseptic effect of three organic acids and the mixed liquid on pork was studied.Use colony count method to analyze the microbes in chilled pork with organic acid.Result showed that 5% malic acid was the best one in single factors,on the 7th day,the total bacteria were 1.7×108cfu·g-1 under 4℃.The 5% mixed liquid of the three organic acids had a good antiseptic effect on pork,and the best formula was lactic acid : malic acid : citric acid =1:1:1,the total bacteria were 3.45×105cfu·g-1 after 7days kept in refrigerator,and the coli form was still below the national standard of pork.The compounds of the three organic acids worked more effectively in inhibition than individual acid.
