Ualitty assessment of some ready-to-eat and locally produced chicken

Abstract EN

50 random chicken meat products (25 of each nuggets and lunch) which were ready-to-eat and locally produced in Egypt, were collected from supermarkets and minimarkets in Damanhour City to assess their quality.

The results of organoleptic and sensory evolution were accented and all the examined samples were in good condition.

The means S.E.M.

of total aerobic, total psychrotrophic, total coliforms and total Staphylococcus aureus in chicken nuggets were : 8.2 X l (f 1.2 X 104, 8.6 X 104 ± 1.5 X 104, 2.4 X 102 ± 8.0 X 10 and 6.0 X 103 ± l Cfu / g, respectively, while in luncheon were : 1.2 X 104 ± 5.9 X 103, 1.5 X i0 ± 1.2 X 104, 5.08 ± 1.61, 2.3 X 103 ± 8.5 X 102 cfu / g, respectively.

This studv mentioned that all nuggets samples and 20% of luncheon samples slighi, exceeded the maximum permissible limit for total aerobic counts (104 cfu / g) according to Egyptian standard specifications Nos.

3493 / 200Q and its amendments in 2003 and 1114 / 2005 of Egyptian Organization fa Standardization and Quality Control-Jt EOSQC".

Also, samples of both products were not be completely free from Staphylococcus aureus but were completely free from Escherichia coli and Salmonellae as pathogenic microorganism.

The chemical examination revealed that the means ± S.E.M.

of hydrogen ion concentrations (pH) were 6.08 ± 0.

And 6.15 ± 0.06 in nuggets and luncheon, respectively, while total volatile basic nitrogen (TVB-N) ranged from 7.53 to 19.35, with a mean ±S.E.M, of 13.36±0.76 mg / l00g in nuggets and ranged from 1.08 to 13.98, with mean± S.E.M.

of 5.54 ± 0.66 mg / l00g in luncheon.

These values of TVB-N were not exceeded the maximum permissible limit, (25and 30 mg / l00g of half partially cooked and completely cooked poultry meal products, respectively) according to ESS No.3493 / 2000.

The fat oxidation criteria determined by thiobarbituric value in both products were very low to be reflected on the flavor and did not exceeded permissible limit (0.9 mg malonaldhyde / kg).
