From ancient times, the plants are used to treat various diseases, to produce perfumes and as ingredients to improve the taste in food. This paper presents a bibliographic and experimental study of the antioxidant and microbial properties of basil, thyme and tarragon. International scientific papers on the use of these plants in the food industry, including the meat industry, are targeted. The role of basil, thyme and tarragon in the manufacture of functional and stable products in storage is mentioned. Percentage decrease in <i>Salmonella Abony</i> growth under the influence of basil constituted 84.4%, thyme 61.6% and tarragon 76.8% after 48 hours of action and respectively 97.2%, 90.2% and 95.3% after 72 hours of action. The interdependence between the percentage reduction of S. Abony infestation and the concentration of basil, mushrooms and tarragon was respectively: basil (R<sup>2</sup> = 0.7725 … 0.7916), thyme (R<sup>2</sup> = 0.7733 … 0.7768), tarragon (R<sup>2</sup> = 0.7689 … 0.8137).展开更多

The GC method used was direct saponification of the samples without derivatizations and the HPLC method was used to extract of the lipid samples. The GC limits of detection and quantification obtained for cholesterol were, respectively, 0.001 and 0.003 mg.g–1. The HPLC values were 0.005 mg.g–1 and 0.016 mg.g–1. The GC recovery rate was 97.10 ± 0.13 and that of HPLC was 93.33 ± 0.22. Comparison of the cholesterol quantity found using the two chromatographic techniques shows that both are capable of quantifying cholesterol in the foods. With regard to costs, analysis time, the cost/benefit relationship was better with gas chromatography than that obtained with high performance liquid chromatography.展开更多

Five formulations (F) of hamburger were prepared from beef and mechanically separated as follows: meat containing sodium erythorbate (F1);deodorized rosemary extract (F2);oregano extract (F3);rosemary plus oregano extracts (F4) and without antioxidant addition, denominated control formulation (CF). The samples were frozen at ?18°C for 24 hours, then submitted to heat treatment in an electric oven with internal controlled temperature of 75°C, and again frozen for a period of 30 days. The lipid oxidation extent (determined by thiobarbituric acid reactive substances— TBRS) was evaluated at 0, 15 during 30 days. After heating in plate to temperature of 75°C, the samples were submitted to color, taste and odor evaluation by 40 untrained tasters. The formulations F1, F2 and F4 presented lower concentrations of TBRS, whereas CF at day zero already showed very high values, indicating oxidation of the product. The samples showed good acceptance in the sensorial analysis.展开更多

Soybean oil was used as partial fat replacer and the lipid profile was modified as a decrease in the n6/n3 ratio (11.59 to 9.50), and atherogenic and trombogenic index (from 0.42 to 0.27 and 0.94 to 0.56 respectively) was observed. Beef patties were added with two MRP levels (1% w/w and 3% w/w). Patties with no antioxidants were used as control and patties containing 0.01% w/w of butylhydroxyanisole (BHA) were used as reference. Oxidative stability of refrigerated vacuum-packed patties was evaluated during 15 days of storage. Results showed 3% of MRP as the most appropriate concentration to prevent lipid oxidation with inhibition percentages of 75%, and 9 days as the limit time of chilled storage regarding consumers’ perceptions.展开更多

In most countries the use of the additive is limited and either the ingoing or the residual amounts are regulated by laws. N-nitrosamines are formed by amines or amino acids with nitrite in meat. Investigations on the occurrence of N-nitrosamines in meat products have been carried out in many countries around the world. In this paper, mechanism of N-nitrosamine formation and its corresponding influence factors in meat products were reviewed. The contents of N-nitrosamines in meat and analytical techniques for the compounds were also described.展开更多

Ground beef in retail display oxidizes at a faster rate than whole muscle products;the use of antioxidants to break the radical chain reaction in the oxidation process is an effective method for slowing oxidation. Soybean is a complex matrix with several bioactive compounds, including peptides and proteins, isoflavones, saponins, and other compounds with antioxidant properties. This study was conducted for 1) to evaluate the antioxidant properties of dry soybeans sprouts (DSS) from Glycine max (L.) Merr., MUNASQA?;2) to evaluate quality characteristics of raw beef patties added with dried soybean sprouts at different levels (0.5%, 1% and 2%) and soybean oil as a replacer of fat;and 3) to estimate color changes and lipid oxidation of n3 fortified raw beef under frozen storage. Results showed that dry soybean sprouts had a high level of superoxide dismutase enzyme, high total phenolics and flavonoids content and appreciable vitamin c content. Although reduction power was low, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzthiazoline-6-ulphonic acid) (ABTS) radicals scavenging activity were elevated. When different concentrations of DSS were incorporated to enriched beef patties with soybean oil, the nutritional value was slightly affected, while that n3 and n6 fatty acid content were increased around three twice. The beef patties formulated with 1% of natural antioxidant showed significantly (p < 0.05) better color stability than those without antioxidants. The lipid oxidation was inhibited in all cases, and was strongly effective at 1% concentration of DSS being the reduced percent of thiobarbituric acid reactive substances (TBARS) comparable to butilated hydroxianisole (BHA). The results shown in this research suggest that dry soybeans sprouts could also be used as a cheap natural antioxidant source for meat products.展开更多
