Cooked Meat Products

Oxidation processes are responsible for reduction of the sensory and nutritional quality of meat and meat products, thus affecting consumer acceptance. The use of sodium nitrite in meat processing is an important factor limiting these changes. Therefore, eliminating this substance from the recipe of meat products to increase their nutritional value is not an easy challenge. The aim of this study was to determine the effect of sodium nitrite reduction on the lipid oxidation (peroxide value, thiobarbituric acid reactive substances), and color parameters (CIE L*a*b*, total heme pigment and heme iron, nitrosylmyoglobin) in cooked meat products during 15 days of vacuum storage. The antioxidant properties of products and isolated peptides (2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS•), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, ferric-reducing antioxidant power) were also evaluated. Experimental material included four different sample groups of cooked meat products produced with various percentages of sodium nitrite (0, 50, 100, and 150 mg kg−1). It was shown that the sodium nitrite dose had no statistically significant effect on lightness (L*) and redness (a*) values, as well as nitrosylmyoglobin content. Along with decreasing the share of sodium nitrite in the samples, the thiobarbituric acid reactive substances (TBARS) value increased from 0.43 mg kg−1 for samples with 150 mg kg−1 at day 0 to 3.14 mg kg−1 for samples without nitrite at day 15. The total ABTS scavenging capacity of the cooked meat samples was in the range 2.48 to 4.31 eqv. mM Trolox per g of product throughout the entire storage period. During storage, the ferric-reducing antioxidant power of samples with nitrite increased from 0.25 to 0.38 eqv. mg/mL ascorbic acid per g of product. In conclusion, reduction of nitrite to the level of 50 mg kg−1 seemed to be comparable with the traditional use of nitrite in meat products in terms of the physicochemical properties and properties related to lipid oxidation, as well as total antioxidant capacity and peptide antioxidant capacity.

Peel Extract

Purpose The purpose of this paper is to investigate the potential of fruit waste materials from fruit industry as sources of powerful natural antioxidants. Design/methodology/approach The peels of mango, rambutan, and santol were extracted and analyzed for their antioxidant activity. Pork ball samples were prepared and treated with different natural extracts at various concentrations, namely 0.05, 0.10, 0.15, and 0.20% (v/w), compared with the control (no natural extract), and then stored at 4°C. The samples were investigated at the zeroth, third, fifth, eighth and tenth day to find out the antioxidant activity of the total phenolic content and lipid oxidation including the evaluation of the change of rancid flavor and color during storage. All statistical results were analyzed by RCBD using SPSS at p⩽0.05. Findings During storage, the amount of phenolic compound in a pork ball by adding fruit extracts at various concentrations slightly decreased, while the lipid oxidation slightly increased. Mango extract showed the best efficiency to delay lipid oxidation in the pork ball for ten days followed by santol extract and rambutan extract. For sensory evaluation, the pork ball with fruit extract at various concentrations showed the lower rancidity development than control, and mango extract at 0.20% (v/w) showed the best delaying rancidity during ten-day storage. Thus, mango peel extract at 0.20% (v/w) showed the highest effectiveness of antioxidant activity against lipid oxidation in pork ball. Originality/value This study was continued from the previous research which investigated the best extraction condition for by-products of mango, rambutan, and santol. From that study, the authors found that the crude extracts need further research on their antioxidant property in foods. The research findings have provided information regarding the interesting new natural antioxidant that can be applied into lipid-containing foods to delay the rancidity and extend the shelf life.

Inhibition of Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes by grape seed extract (ActiVin) and pine bark extract (Pycnogenol) and the effect of these natural extracts on the oxidative stability of raw ground beef were studied. In an agar dilution test, the MICs of ActiVin and Pycnogenol were determined to be 4.0 mg/ml for 4.43 log CFU per plate of E. coli O157:H7 and 4.0 mg/ml for 4.38 log CFU per plate of L. monocytogenes. In an inhibition curve test, populations of E. coli O157:H7, Salmonella Typhimurium, and L. monocytogenes fell to below the detection limit (10 CFU/ml) after 16 h of incubation. The numbers of E. coli O157:H7, L. monocytogenes, and Salmonella Typhimurium declined by 1.08, 1.24, and 1.33 log CFU/g, respectively, in raw ground beef treated with 1% Pycnogenol after 9 days of refrigerated storage. ActiVin (1%) and oleoresin rosemary (1%) resulted in an approximately 1-log CFU/g reduction in the populations of all three pathogens after 9 days. The addition of 1% ActiVin and Pycnogenol contributed to the maintenance of an acidic pH of 5.80 and 5.58, respectively, in raw ground beef. Compared to the control, all treatments increased in L* (lightness), with the exception of ActiVin. ActiVin and oleoresin rosemary had the highest a* (redness) and b* (yellowness) values, respectively. ActiVin most effectively retarded lipid oxidation, followed by Pycnogenol. The results suggest that these natural extracts have potential to be used with other preservative methods to reduce pathogenic numbers, lipid oxidation, and color degradation in ground beef.

Effect of various technological processes and raw material quality on physical properties and oxidative status of dalmatian pancetta We have conducted the research on processing technology features, and physical properties of raw materials and finished products, as well as determined the level of lipid oxidation (TBA test) of final products, which indicates the safety of products and applied technology, in three Dalmatian processing facilities to determine the specifics of processing technology, implemented technology standardization strategies and the quality of traditional Dalmatian Pancetta. During our research we have recorded due details of technological procedures that were either identical or very similar in all three facilities, facility specific procedures (the length of curing phase: facility A – 14 days, facility B – 10 days, facility C – 4 days; the length of drying/ripening phase: facility A – 76 days, facility B - 80 days, facility C – 63 days) and facility micro-climate parameters (temperature, humidity and air flow). Based on identified differences in the length of processing, the weight of raw materials (class A ≥ 4.5 kg; class B > 3 < 4.5 kg), the use of defrosted raw materials (class BS), the method of curing (sea salt; sea salt + sodium nitrite; sea salt + sodium nitrite + seasoning and additives) and the quantity of used salt (from 3.21 % to 8.81 %), we have grouped our samples into 10 groups that were allocated between the 3 facilities. We have monitored the following technological parameters during the processing: quality of raw materials (origin, initial weight, length, width, pH); cooking loss per individual processing phase (curing and drying/ripening), total processing cooking loss, and quality of matured bacon (pancetta) (weight, length, pH, aw, malonaldehyde content). The loss of product weight (cooking loss) during the processing ranged from 24.28 % to 42.73 %, with the highest total cooking loss (46.86 %) measured for the class BS bacon, probably not only as a result of raw material freezing/defrosting, but lower initial weight and longer duration of processing procedure. Consequently, the class A Dalmatian Pancetta had the highest final weight (from 2.60 to 3.88 kg), while class B (from 1.75 to 3.30 kg) and class BS (from 1.75 to 2.80 kg) had the lowest final weight. Dimensions of mature bacon amounted to 38-56 cm x 16-24 cm. The initial pH of raw bacon was similar in all researched groups. Mature bacon produced in facility C, in which both classes of bacon were cured by sea salt exclusively, had a significantly higher pH (P≤0.05): class A – 6.09; class B – 6.12. The class BS bacon, at the same time, measured the lowest aw (P ≤ 0.05) (0.75), while bacons processed in facility C measured the highest aw (class B – 0.87; class A – 0.89). Bacons cured with the combination of salt, seasoning and additives (class A – 0.16 mg/kg; class B – 0.18 mg/kg) and bacon produced in facility C (0.18 mg/kg) had the lowest malonaldehyde content (0.16 to 0.18 mg/kg), while the class BS bacon cured with the mixture of sea salt and sodium nitrite had the highest malonaldehyde content. The analysis of our research results implies that greater initial weight of raw materials, longer processing and the use of defrosted raw materials have a significant impact on the increase of cooking loss, the decrease of aw and the increase of the level of lipid oxidation of mature bacon (P ≤ 0.05). Judging by the level of water activity (aw< 0.93) and the low level of lipid oxidation measured in mature products of all product groups, allocated among all three facilities, we can conclude that the traditional Dalmatian Pancetta is a product that is safe for consumption which complies with all the prescribed conditions for dry-cured meat products. However, since certain technological processes in different facilities varied considerably, to determine their impact on other parameters of the quality of the final product, with the aim of standardization of technology and improving the quality of traditional Dalmatian Pancetta, additional research is necessary.

Antioxidant And Antimicrobial Activity

Natural extracts (rich in bioactive compounds) that can be obtained from the leaves, peels and seeds, such as the studied extracts of Pomegranate (P), Rosemary (RA, Nutrox OS (NOS) and Nutrox OVS (NOVS)), and olive (Olea europaea) extracts rich in hydroxytyrosol (HYT-F from olive fruit and HYT-L from olive leaf) can act as antioxidant and antimicrobial agents in food products to replace synthetic additives. The total phenolic compounds, antioxidant capacity (measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-Azinobis (3-ethylbenzothiazolin) -6-sulphonic acid (ABTS), Ferric Reducing Antioxidant Power (FRAP), and Oxygen Radical Absorbance Capacity (ORACH)) and their antimicrobial power (using the diffusion disk method with the Escherichia Coli, Lysteria monocytogenes, and Staphilococcus Aureus strains) were measured. The results showed that all the extracts were good antioxidant and antimicrobial compounds in vitro. On the other hand, their antioxidant and antimicrobial capacity was also measured in fish products acting as preservative agents. For that, volatile fatty acid compounds were analysed by GS-MS at day 0 and 11 from elaboration, together with total vial count (TVC), total coliform count (TCC), E. Coli, and L. monocytogenes content at day 0, 4, 7 and 11 under refrigerated storage. The fish patties suffered rapid lipid oxidation and odour and flavour spoilage associated with slight rancidity. Natural extracts from pomegranate, rosemary, and hydroxytyrosol delayed the lipid oxidation, measured as volatile compounds, and the microbiological spoilage in fish patties. Addition of natural extracts to fish products contributed to extend the shelf life of fish under retail display conditions.

This study focuses on collecting actual data on the workable possibility of reducing the technological use of nitrites in beef products according to the present trends in nutrition, especially in terms of European Union (EU) food law. Measurements of safety by technological (pH value, water activity, N-nitrosamine), microbiological, oxidative stability (thiobarbituric acid reactive substances, oxidation-reduction potential), and color parameter (CIE L*a*b*, total heme pigment and heme iron) methods were taken after production and storage. The roasted beef with a reduced inclusion level of sodium nitrite (75 mg/kg and below) was more vulnerable to lipid oxidation. The quantities of primary lipid oxidation products were related to the sodium nitrite inclusion level (50–150 mg/kg). Clostridium spp., Staphylococcus aureus, and Listeria monocytogenes were not detected in any of the samples tested during all the experiments. The total count of Enterobacteriaceae increased with the decrease in sodium nitrite content, from log 2.75 cfu/g at the highest to log 6.03 cfu/g at the smallest addition of nitrite. The obtained results revealed that the addition of 100 mg/kg of sodium nitrite would be adequate for minced roasted beef, without significant unexpected effects on color, oxidative stability, and microbiological safety compared with the control (150 mg/kg).
