Preservation of meat and meat products is important due to its short shelf life and perishability. The pastoralists of Northern Kenya processed and preserved traditional meat products for consumption. The traditional meat products are relished food both for nutritional and cultural heritage among the Borana pastoralists. The study was carried out to assess the microbial safety and chemical quality of traditional meat products. The samples were collected immediately after processing and transported in a cool box to the food laboratory for microbial analysis and determination of changes related to lipid oxidation during storage for seven weeks at ambient temperature and at refrigerated temperature (5 °C). Microbiological quality of the samples was assessed by Total Viable Count (TVC), Escherichia coli count, Staphylococcus aureus count and yeast and mold count. Result showed that Staphylococcus aureus, yeasts and molds were detected in the products and there was increase of Staphylococcus aureus count from (1.44 log10 CFU/g) to (2.28 log10 CFU/g)) during storage at ambient temperature for seven weeks. Samples stored at refrigerated 5oC showed less counts of microbial load. The peroxide value, acid value and thiobarbituric acid levels were below the value associated with meat spoilage during the expected shelf life. Reduction of moisture during drying of traditional meat products and cooking of meat at high temperature contributed towards reduction of microbial load. However, poor handling and post contamination may lead to poor microbial quality of traditional meat products.

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

The study aimed to assess the effect of herbal additions with antioxidant properties (pepper, thyme and oregano) on the microbiological and oxidative stability as well as the sensory quality of minced poultry meat. Meatballs treatments without additives and treatments with the addition of three types of spices in two forms—dry spices and industrial extracts were examined. Popular seasoning additives of oregano (Origanum vulgare), thyme (Thymus vulgaris) and black pepper (Piper nigrum) at 0.3% of dry herbal or 0.003% as industrial extract were added to minced meat. The microbiological, chemical and sensory tests were performed at specified times and storage temperature. Based on the studied criteria, products maintained constant and adequate quality by up to 10 days while stored in 4 °C. In the case of all tested samples, the overall sensory quality began to deteriorate after 10 days of storage. The preservative role of herbs and extracts in meat products during processing and storage was observed. Oregano and black pepper in both forms maintained good microbial quality and showed their inhibitory effects on the growth of psychrotrophic bacteria. It was observed that dried herbs revealed a stronger antioxidant effect than additives in the form of extracts. The studied dried herbs played an antioxidant, antimicrobial and preservative role in meat products during processing and storage.

Abstract Beef chuck and plate cuts obtained from U.S.D.A. utility grade carcass were mixed and ground through a 0.318 cm plate. The ground meat was extended with extruded and non-extruded defatted peanut meal. Hydrated defatted peanut meal was added at the rate of 20 and 30 parts to 80 and 70 parts of the ground meat, respectively. All treatments were formulated to contain 20% fat in the final patty and loaf products. Extruded and non-extruded meat products were stored at −18 C for periods up to 6 weeks. All quality evaluations were conducted on cooked meat products. Ground meat patties and loaves extended with non-extruded peanut meal exhibited similar cooking losses to those either extended with extruded peanut meal or 100% beef products. Control meat products stored for 4 weeks or longer required larger forces to shear than the non-stored patties. Freezing storage of the extended meat products did not result in a change of shearing forces. These forces were similar to the shearing force exhibited by freshly prepared products. Trained sensory panelists indicated that extended meat patties were more tender and less cohesive than non-extended patties. However, sensory acceptability tests indicated similar acceptability ratings for the extended and non-extended meat patties and loaves.

AbstractOrganic meat products are gaining consumer interest worldwide. The aim of this study was to investigate the effect of organic and conventional meat origin on nutritional determinants of the following pork meat cuts: loin, ham, and shoulder. Nutritional value of meat was based on selected indicators such as proximate composition, the concentration of cholesterol, vitamin E content and minerals and trace elements such as calcium, magnesium, potassium, copper, iron, and zinc, and the composition of fatty acids. The results of this study demonstrated that higher contents of protein and selected mineral compounds, as well as lower vitamin E concentration and different fatty acids (i.e., C12:0, C17:0, C17:1 n-7, C18:3 n-6, C24:0 and total n-3 polyunsaturated fatty acids (PUFA)) distinguish organic pork meat cuts from the conventional counterparts. The organically meat parts, especially the shoulder, were identified as a better source of copper, calcium, iron and zinc, while organic ham and loin had more potassium. On the other hand, organic hams were shown to have lower content of vitamin E in comparison to their conventional equivalents present. Also, in organic shoulders showed a higher n-6/n-3 ratio compared to meat of conventional origin.

Consumption of processed meat products has greatly increased due to availability and accessibility of ready to eat meat products. Despite increased patronage of ready to eat meat products, food safety implication of processed ready-to-eat-meat products is of global concern. Against this background, this study was aimed at assessing the quality and safety of processed ready to eat meat products sold in Ibadan. Samples of asun, suya and kundi were randomly collected from four selected markets in Ibadan metropolis and subjected to chemical analyses. The total cholesterol content in suya (1538.00 mg/100mg) was significantly higher (P<0.05) than in asun (1277.60 mg/100mg) and kundi (1277.60 mg/100mg). Kundi had significantly (P<0.005) higher crude protein (70.66 %) and ether extract (23.42 %) than asun with 20.17 % and 10.85 % ether extract, respectively. Lipid peroxidation of suya (6.18 mg/MDA/kg) at day 28 was significantly higher (P<0.05) than kundi (4.50 mg/MDA/kg) and asun (4.19 mg/MDA/kg). The total polycyclic aromatic hydrocarbon (TPAH) was 5.31μg/kg in suya, 2.02μg/kg in asun and 1.55μg/kg in kundi. The total heterocyclic aromatic amine (THAA) was 51.66 ng/g in suya, 28.12 ng/g in asun and 23.70 ng/g in kundi. The total heterotrophic bacteria count in suya (28.17 ×10-3cfu/g) was higher than in kundi (11.19 ×10-3cfu/g) and asun (3.99×10-3cfu/g). Therefore, safe keeping and quality of suya in Ibadan metropolis was low based on the above parameters measured.

The objective of this study was to evaluate the use of high pressure processing (HPP) as a preservation method of meat products. Vacuum-packaged fish patties were subjected to HPP (300 MPa for 30 min 15°C or 500 Mpa for 10 min at 15°C). Untreated samples represented the control group. The three groups were stored at 4°C for 0–5 weeks. Color parameters, pH, thiobarbituric (TBARS), bacterial growth, and Oxidation-Reduction Potential (ORP) were determined. The results revealed that the 500-MPa treatment inhibited bacterial growth and extended the shelf-life of fish patties to four weeks with insignificant effects on the physicochemical attributes.
