| Abstract Low fat fresh goat sausages based on chitosan (LMWC) and derivative chitosan (LMWC-Glc) were developed aiming to produce a functional food product evaluating the effect of inclusion of these compounds on quality, stability and shelf life. Goat sausages (10% pork fat) were formulated with 2% (w/w) of LMWC or LMWC-Glc and stored at 4 °C during 21 days. Results indicated that incorporation of LMWC-Glc and LMWC is technologically feasible, originating a potential functional product with low fat content, besides the positive impact on microbial safety. The modified LMWC (towards better solubility and lower adstringency) incorporated at 2% as functional ingredient maintained positive effect on antimicrobial, nutrional, textural and sensory performance.... |

| Abstract The aim of this study was to investigate the effect of acid pretreatment, temperature and enzyme concentration on the acid-enzymatic extraction of soluble collagen from chicken keel bone cartilage. A chemical composition analysis and protein profile characterization of this slaughter by-product were also conducted. The cartilages were extracted with 0.5 mol/L of acetic, lactic and citric acids for 24, 48 and 72 hours. Subsequently, optimization with a 22 factorial design was performed with three replications at the central point for a total of 7 experiments; the analyzed response was the collagen content of the obtained isolates. The cartilage under study has a high protein content (90.27% dry basis) consisting of approximately 35.7% collagen and... |

| Abstract This work aims to investigate the incidence of two color abnormalities in broiler meat: PFN (Pale, Firm, Non-exudative) and PSE (Pale, Soft, Exudative), as well as the physicochemical alterations promoted by those anomalies. The samples of broiler breast meat (n = 700) were classified as Normal (44<L*<53, pH>5.8), PSE (L*≥53, pH<5.8) and PFN (L*≥53; pH>5.8). The occurrence of Normal, PSE and PFN samples was 69%, 11% and 20%, respectively. PFN samples presented a 4.2% higher water-holding capacity compared to PSE meat. PSE meats displayed a higher MFI (89.4) when compared to PFN and Normal meats. It was also noticed that the levels of lipid oxidation were greater in PSE breasts compared to Normal breasts. The total carbonyl in PFN,... |

| Abstract Brazilian wine production is characterized by Vitis labrusca grape varieties, especially the economically important Isabel cultivar, with over 80% of its production destined for table wine production. The objective of this study was to optimize and validate the conditions for extracting volatile compounds from wine with the solid-phase microextraction technique, using the response surface method. Based on the response surface analysis, it can be concluded that the central point values maximize the process of extracting volatile compounds from wine, i.e., an equilibrium time of 15 minutes, an extraction time of 35 minutes, and an extraction temperature of 30 °C. Esters were the most numerous compounds found under these extraction conditions,... |

| Abstract Considering the potential consumption and economic the importance that Isabella and Ives wines represent in the Brazilian consumer market as well as the scarcity of scientific data examining their quality, the objective of this study was to investigate the sensory quality and the volatiles profile of these wines. The volatile compounds were extracted by headspace solid-phase microextraction (HS-SPME) and a total of 54 compounds were detected in red wine samples including esters (23), terpenes (12), alcohols (10), aldehydes and ketones (5) and amines (1) as well as 3 compounds belonging to other classes. Isabella and Ives red wines were sensorially characterized by 14 descriptors, through quantitative descriptive analysis (QDA). The PCAs fruity... |

| Abstract The objective of this study was to evaluate the quality of commercial red wines (Isabella and Ives [IsB]; Isabella, Ives, Seibel and Concord [IsSC]; and Isabella and Ives [IsBb]) produced from Isabella and Ives grapes grown in southern Brazil. The parameters required by Brazilian law were evaluated, and the chemical parameters of the phenolic compounds, organic acids, anthocyanins and antioxidant capacity were quantified for red wine samples containing the Isabella and Ives grape. All of the wine parameters were consistent with Brazilian legislation. There were significant differences (p<0.05) among the wines in phenolic compound content, flavonoids, antioxidant activity measured by the oxygen radical absorbance capacity (ORAC) and... |

| Abstract The objective of this study was to extract collagen from chicken feet, determining optimal extraction conditions according to acetic acid concentration, pepsin content and time of enzymatic hydrolysis. A factorial design 23 was used, with three replications at the central point, totaling 11 experiments. The response variable studied was the collagen content of the isolate obtained. In addition to the optimization, the characterization of the isolates with higher and lower collagen content, in relation to the amino acid profile, electrophoretic profile, peptide hydrophobicity and functional properties, such as water solubility, water retention capacity and emulsifying activity, were carried out. The proposed model was statistically significant,... |

| Abstract Caprine Coalho cheese presents great potential for a typical protected designation of origin, considering that this traditional Brazilian cheese presents a slightly salty and acid flavor, combined with a unique texture. This study optimized the HS-SPME-GC-MS methodology for volatile analysis of Coalho cheese, which can be used as a tool to help in the identification of the distinctive aroma profile of this cheese. The conditions of equilibrium time, extraction temperature and time were optimized using the statistical tool factorial experimental design 23, and applying the desirability function. After the evaluation, it was concluded that the optimum extraction conditions comprised equilibrium and extraction time of 20 and 40 minutes, respectively;... |
