| AbstractThe effect of anacardic acid on lipid stability and coloration of chicken mortadella was investigated. Antioxidants were added to chicken mortadellas, according to the treatments: no added antioxidant, 100 ppm butylated hydroxytoluene and 50, 100, 150 and 200 ppm anacardic acid. The mortadellas were stored for 90 days at 4 °C, and the analysis of lipid oxidation and color were performed. For TBARS, there was linear reduction with increased anacardic acid. According to the means test, 200 ppm anacardic acid provided the lower TBARS values. The redness decreased during storage, and, as reported by the means test, mortadella containing 200 ppm anacardic acid had lower values. The lightness of mortadellas decreased during storage. Also in accordance... |

| The effects of mango seed extract (MSE) and butylated hydroxytoluene (BHT) on pH, lipid oxidation, and color of Bologna-type mortadella during refrigerated storage for 21 days were studied. Bologna-type mortadella samples were formulated to contain 0.1% MSE, 0.2% MSE, or 0.01% BHT. After 14 days of storage, the products containing MSE 0.1 or 0.2% had higher pH values than those containing BHT 0.01%. Lipid oxidation values increased with storage time but were not affected by the type of antioxidant. The highest values for color parameter L* were observed for mortadella containing BHT 0.01% after 7, 14, and 21 days of storage. Values for the color parameters a* and b* tended to decrease during mortadella storage. Products containing 0.1 or 0.2% MSE showed... |

| We investigated lipid oxidation, instrumental color evaluation, and sensory characteristics in cooked pork sausages containing anthocyanin rich colored potato (Solanum tuberosam cv. Shadow Queen) flakes (CPF). According to the thiobarbituric acid reactive substance values, addition of 2% CPF suppressed lipid oxidation (P < 0.05) by 80% compared to the control. The antioxidant activity of 2% CPF was comparable to the synthetic antioxidant butylated hydroxytoluene (0.1%) in cooked pork sausages. The L, a* values and odor, flavor, taste, texture and overall sensory quality did not significantly differ between control and 2% CPF. Overall, cooked pork sausage with 2% CPF was as acceptable to consumers as the control. Thus, the present study indicated that... |

| Abstract: The objective of this work was to evaluate the physicochemical attributes and vitamin C contents of fruits of five Brazilian genotypes of feijoa (Acca sellowiana), at harvest and after cold storage. The Alcântara, Mattos, Helena, and Nonante cultivars, as well as accession 2316, were studied. The assessed attributes were: fresh mass loss, titratable acidity, soluble solids contents, soluble solids contents/titratable acidity ratio, pH, skin and flesh color, texture, and vitamin C contents (skin and flesh). After storage, there were reductions of 2.9% in soluble solids contents, of 32.2% in titratable acidity, and of approximately 85% in texture attributes, besides increases of 36.3% in the soluble solids contents/titratable acidity ratio and of... |

| ABSTRACT The 7-week feeding trial evaluated the effect of 2% grapeseed meal used as natural antioxidant in the diets for slow-growing Hubbard broiler chicks, aged 14 days. The chicks were weighed individually and assigned to two groups (C and E), with 40 chicks per group, housed under conditions of temperature, humidity and light regimen according to the hybrid management guide. The basal ingredients of the conventional diet were corn, wheat, gluten, soybean meal and 2% flaxseed meal, which is rich in polyunsaturated fatty acids. Compared to the control formulation, the experimental formulation included 2% grapeseed meal, both in the growing and finishing stages. The broilers had free access to feed and water. In the end of the feeding trial, blood samples... |

| Consumers are becoming more aware of the toxicological implications of artificial additives in foods. Natural antioxidants, in addition to reducing the deleterious effects of lipid oxidation, are currently extremely highly valued. This study aimed to invetigate the effect of addition of sun mushroom (Agaricus blazei Murrill) powder on the oxidative and microbiological stability of pork sausage during the shelf life. This powder was used at concentrations of 0.0%, 1.0%, 2.0% and 4.0% in the sausages. Analyses of moisture, protein, ash, fat and microbiological analyses were performed on day 0. The sausages were analyzed on day 0 and every seven days in terms of pH, color, TBARS values and microbiological analyses. The results of the proximal composition... |

| L-3-n-butylphthalide (L-NBP) is a naturally occurring antioxidant, which can be used for the treatment of acute ischemic stroke and vascular dementia. This study evaluated the safety, tolerability and pharmacokinetics of L-NBP tablets in healthy Chinese volunteers. This was a single-center, randomized, double-blind, placebo-controlled, single- and multiple-dose study. Subjects were assigned to receive a single dose of L-NBP tablet at either 80, 160, 320, or 480 mg (n=40), or multiple doses of 160 mg twice daily for 7 days (n=12). Plasma samples were analyzed with LC-MS/MS. Pharmacokinetic parameters of L-NBP were calculated using non-compartmental analysis with WinNonlin software. Statistical analysis was performed using SPSS software. All adverse events... |

| The effect of two levels (0.5 and 1%) of hydroalcoholic extract of Achyrocline satureioides on the safety (TBARS values) and quality (pH, water activity, colour, weight loss, and sensorial attributes) of salami was evaluated. The addition of Achyrocline satureioides extract decreased TBARS values significantly during the storage of salami when compared to the control, which was elaborated without Achyrocline satureioides extract. The treatment with 1% of "Marcela" extract showed larger lipid stability than that of the lot with 0.5%, However, it presented a decrease (p < 0.05) in the sensorial acceptance. The two levels of "Marcela" extract did not influence pH, water activity, colour, and weight loss significantly. This study indicates that the... |

| ABSTRACT: The aim of this study was to evaluate the effect of extraction conditions on bioactive compounds, as well as on antioxidant activity, and the antimicrobial activity of the extracts with the highest antioxidant characteristics. The extracts were obtained by conventional method and ultrasound-assisted extraction at various temperatures (20°C, 40°C and 60°C). Total phenolics, total flavonoids, antimicrobial activity and antioxidant activity were quantified by the methods of DPPH, FRAP, and ORAC, respectively. The conventional extraction method and ultrasound method influenced the phenolic content at all the tested temperatures. Flavonoids were not influenced by extraction methods. The antioxidant activity (DPPH) was highest in the ultrasonic method... |
