ABSTRACT: Enzymatic hydrolysis (pepsin) assisted with or without ultrasound in the functional properties of hydrolyzates from different collagens were analyzed. Degree of hydrolysis, antioxidant activity (DPPH) and antimicrobial activity (MIC) were assessed. The treatment that resulted in greater antioxidant activity for the fiber sample was with the use of 4% of enzyme and concomitant ultrasound (40.7%), leading to a degree of hydrolysis of 21.7%. For the powdered fiber sample the hydrolysis treatment with use of 4% of enzyme resulted in lower protein content (6.97mg/mL), higher degree of hydrolysis (19.9%) and greater antioxidant activity (38.6%). The hydrolyzates showed inhibitory capacity against gram-negative bacteria Salmonella choleraesuis and... |

ABSTRACT: Milk supply chain in Brazil exhibits significant production system heterogeneity in all federal units. Thus, the objective of this study was to form homogeneous groups of bovine milk production units based on the chemical and microbiological quality of the milk via multivariate statistical techniques. A total of 1,541 milk producing units (MPUs), corresponding to 44,089 samples, were analyzed. The first three principal components accounted for 81.38% of the total variation in the data. Principal component 1 (PC1) was associated with the chemical quality of milk (fat, protein [PROT] and total dry extract [TDE] content), while PC2 and PC3 were associated with microbiological quality (somatic cell count [SCC] and total bacterial count [TBC]). The... |

ABSTRACT The aim of this study was to evaluate the effect of different levels of cottonseed (0, 100, 200, 300 and 400 g Kg-1) on the physical and chemical parameters of the meat of finishing lambs. Forty-five uncastrated male lambs were distributed in a completely randomised design with five treatments of nine replications. The pH values were not influenced by the levels of cottonseed. The lipid and ash content showed significant differences, but were not adjusted by the linear or quadratic equations. Losses during thawing increased, as did cohesiveness, and water activity and water retention capacity decreased as the levels of cottonseed in the diet rose. Tocopherols, cooking loss, toughness and chewiness were adjusted using quadratic equations. In the... |
