Chicken Meat

A total number of 100 samples from ten random broiler chicken carcasses (breast and thigh) were collected from an automatic poultry slaughtering plant in Ismailia city, Egypt. The mean values of Enterobacteriacae count were 5.9x104±9.7x103 cfu/g and 7.1x 104 ± 1.1x104 cfu/g for chicken breast and thigh samples respectively. The prevalence of E.coli were 12% and 9% breast and thigh samples examined, respectively. They are serologically identified as 33.35 and 22.2% O 157 :H 7 (EHEC) , 16.6% and 11.1% O114:H21 (EPEC), 16.6% and 33.3 %O127:H6 (ETEC) , 0% and 0% O126 (ETEC) and 33.3% and 0% O26 (EHEC) for breast and thigh samples, respectively. The incidence of E.coli O 157 :H 7 was 100% in both serological and PCR methods from biochemical positive E.coli samples. Culture is specific and cheap whereas PCR is sensitive and expensive, hence, we recommend both culture and molecular methods, which improve sensitivity and specificity, to enhance detection of foodborne pathogens including E.coli.

This experiment was conducted to determine the effects of enrichment housing design on performance, selected welfare indicators, chicken meat composition and serum cholesterol concentration of broiler chicken. For this purpose, 480 Ross-308 chicks were assigned to two groups, Control and Test, each with 4 replications. The pens of the Test Group were enriched with perches and sand bedding. At the end of the study, 8 males and 8 females whose live weights were close to the group average from each group were slaughtered. Their blood was collected and serum was separated. For chemical analysis of the chicken meat, whole carcasses of 4 males and 4 females, and half of the breast and left thigh from the remaining 4 males and 4 females were collected. In the carcass group, whole carcass with its bones was minced, whereas in the other groups breast and tight meat were separated from the bones and minced in a meat grinder, homogenized with an electronic mixer, then flash frozen (-40 °C, 8–1...

The study was conducted to evaluate the utilization of skin in the preparation of meat balls. The meat balls were prepared by incorporating skin at different levels viz. 25%, 50%, 75% and 100% replacing lean meat in the formulation. The meat balls were further enrobed to see the effect of coating on the quality characteristics of meat balls. Parameters namely emulsion stability, cooking yield, proximate composition and sensory parameters of meat balls decreased significantly (P LDPE) pouches and were analyzed at a regular interval of 0, 7 and 14 days for various quality parameters during refrigerated storage at 4±1°C. TBARS value, total plate count and psychrophilic count increased significantly (P P 

The spray drying of a chicken meat protein hydrolysate was studied in order to evaluate the effect of carrier agents on the physicochemical properties of the powders. The protein hydrolysate was obtained by enzymatic hydrolysis, which was carried out at 52.5 °C with a 4.2 g enzyme/100 g protein and a pH value of 8.0. The drying was carried out in a laboratory spray dryer, and maltodextrin and gum Arabic were used as carrier agents at three concentrations. Several physicochemical properties (moisture content, bulk density, distribution and mean diameter particle, hygroscopicity and glass transition temperature) of protein hydrolysate powders were measured. These results indicated that an increasing carrier agent concentration decreased the powder moisture content and bulk density. Mean diameter particle increased with increasing maltodextrin or gum Arabic concentration, which is related to the feed viscosity. The addition of maltodextrin or gum Arabic in the feed solution also contributed significantly to powder stability since powder hygroscopicity decreased and glass transition temperature increased with increasing carrier agent concentration.

Background and Aim: Chicken meat can be contaminated by microorganisms anywhere in the supply chain, from farm to market, and these microorganisms can be transmitted to humans through direct contact, contact with the environment, and food consumption. The microbial contamination has a serious impact on public health. This study aimed to analyze the microbial contamination of chicken meat sampled from local markets in Surabaya, East Java, Indonesia.

Materials and Methods: A total of 60 samples of fresh chicken meat obtained from 10 traditional markets (six samples per market) were examined for the presence of bacteria. Staphylococcus aureus, Salmonella spp., and Escherichia coli were identified using Gram staining, culturing, and biochemical tests. The most probable number (MPN) method was used to identify E. coli.

Results: Most chicken meat samples were positive for S. aureus (58.3%), Salmonella spp. (48.3%), and E. coli (40%). The samples were considered positive for E. coli if the MPN value was higher than 1×101 CFU/g.

Conclusion: High microbial contamination was found in all the chicken meat sampled from local markets in Surabaya. Such contamination can lead to foodborne diseases so, proper hygiene and sanitation standards should be followed from slaughterhouses to the end-users.

From all types of treatments used to improve meat tenderness (mechanical, chemical, enzymatic tenderization), has been studied the enzymatic tenderization with papain a tropical plant enzyme derived from papaya. In this research has been evaluated papain influence on adult beef because pork, mutton and chicken meat are enough tender. Papain was added in injection brine and than the beef cuts was injected with a specific percent of brine. Experimental data indicate that papain weaken beef meat structure produced improvement of functional properties of adult beef. Papain attacks connective tissue and myofibril proteins determinate increase of hydroxiproline and free amino acids content in boiled beef cuts. A significant increase in tenderness by rigidity index measurement was observed in the meats treated with papain as compared with the control. The sensorial tests of beef treated with papain were bigger than control. This experiment confirms that papain is a proteolytic enzyme that ...

Battered and breaded chicken meat products are one of the most popular consumer items that have traditionally been consumed in many countries and form an integral part of human foods because of the increased palatability provided by soft and moist interior with porous outer crispy crust. Total of 60 random Samples of battered and breaded chicken meat products including drumstick and wings (30 of each) were collected from different supermarkets in different localities in Qalubyia Governorate. The collected samples were transferred directly to the laboratory in an ice box under complete aseptic condition without undue delay and then subjected to following examinations. sen sor y a n a l ysi s of ba t t er i n g a n d br ea di n g ch a r a ct er i st i cs wa s a ppl i ed.

This study evaluated the effect of modified atmosphere packaging on shelf-life extension of a precooked chicken meat product stored at 4°C using microbiological, physico-chemical and sensory analyses. The following gas mixtures were used: M1: 30%/70% (CO2/N2), M2: 60%/40% (CO2/N2) and M3: 90%/10% (CO2/N2). Identical chicken samples were aerobically packaged and used as control samples. Sampling was carried out at predetermined time intervals namely: 0, 4, 8, 12, 16 and 20 days. Total viable counts (TVC), Lactic acid bacteria (LAB), Brochothrix thermosphacta, pseudomonads, yeasts and molds, and Enterobacteriaceae were monitored. TVC of precooked chicken product reached 7 log cfu/g, after days 12 and 16 of storage (air and M1 samples), respectively. The M2 and M3 gas mixture packaged samples did not reach this value throughout the 20 days storage period under refrigeration. LAB and to a lesser degree B. thermosphacta, constituted part of the natural microflora of precooked chicken samples stored in air and under MAP reaching 7.0–8.1 log cfu/g at the end of storage period. Of the remaining bacterial species monitored, both pseudomonads and yeasts/molds were significantly higher (P<0.05)(P<0.05) for chicken samples stored in air than under MAP (M1, M2, M3) throughout the entire storage period under refrigeration. Finally, counts of Enterobacteriaceae were low (<2 log cfu/g) in all chicken samples irrespective of the packaging conditions throughout the entire storage period. Of the chemical indices determined, thiobarbituric (TBA) values in all cases remained low, equal or lower than 3.0 mg malonaldehyde (MA)/kg during the entire storage period. Results of the present work show that the limit of sensory acceptability was only reached for the aerobically stored and M1 gas mixture chicken samples somewhat before days 16 and 20 of storage, respectively. This limit coincided with high TVC and LAB populations (>6.8 log cfu/g), increased lipid oxidation (aerobic storage only) and apparent growth of yeasts/moulds on the surface of chicken samples. The use of MAP as shown in the present study, resulted in an extension of shelf-life of precooked chicken by ca. 4 days (M1 gas mixture), and by more than 6 days (M2 and M3 gas mixtures), respectively. Precooked chicken meat was better preserved under M2 and M3 mixtures maintaining desirable odor/taste attributes even on final day of storage tested.
