| As caseínas compreendem cerca de 80% das proteínas presentes no leite. Além disso elas são um dos componentes mais importantes para as suas características organolépticas, bem como no seu rendimento industrial. No entanto, alguns fatores afetam a estrutura dessa proteína, e com isso modificam as características reológicas dos derivados lácteos. Dada estas importâncias, estimar o tamanho médio da caseína em amostras de leite é amplamente aplicável para determinar as características sensoriais do leite, seu rendimento industrial ou mesmo as características reológicas dos derivados. Neste contexto, o objetivo desse trabalho foi avaliar a interferência dos conservantes Adiziol e Bronopol na estocagem do leite. Material e Métodos: Cinquenta e três amostras de... |

| The interaction of the cyanidin, pelargonidin, catechin, myrecetin and kaempferol with casein and gelatin, as proline rich proteins (PRPs), was studied. The binding constants calculated for both flavonoid-casein and flavonoid-gelatin were fairly large (105–107 M−1) indicating strong interaction. Due to higher proline content in gelatin, the binding constants of flavonoid-gelatin (2.5 × 105–6.2 × 107M−1) were found to be higher than flavonoid-casein (1.2 × 105–5.0 × 107 M−1). All the flavonoids showed significant antibacterial activity against the tested strains. Significant loss in activity was observed due to the complexation with PRPs confirming that binding effectively reduced the concentration of the free flavonoids to be available for antibacterial... |

| Avaliaram-se os componentes, as frações de caseína e o rendimento na produção de queijo do leite de cabras das raças Saanen e Anglo-Nubiana, principais raças criadas no Uruguai. O estudo foi realizado em uma fazenda com sistema de criação semi-intensiva. O leite das cabras Anglo-Nubianas apresentou teores mais elevados de gordura (4,65 vs 3,59%), proteína total (3,48 vs 2,84%), caseína total (2,82 vs 2,23%), e maior rendimento na produção de queijos (22,00 vs 15,03kg/100l) que o leite das cabras Saanen. As fraçoes de αs1-caseína (6,99 vs 2,37g/l), β-caseína (13,95 vs 12,75g/l) e κ-caseína (4,24 vs 3,64g/l) também foram mais elevadas no leite das cabras Anglo-Nubianas, porém no teor de αs2-caseína (3,02 vs 3,60g/l) não se observaram diferenças. O rendimento... |

| The objective of this work was to evaluate the in vitro degradation dynamics of neutral detergent fiber (NDF) of high-quality tropical forage according to supplementation with different nitrogenous compounds sources. A signal grass sample harvested during rainy season was used as basal forage. Casein was used as true protein source and urea:ammonium sulfate (U:AS, 9:1) mixture (urea) as non-protein nitrogen source. The first three supplements were the addition of 0.5, 1.0 and 2.0 mg of casein per mL of final incubation solution. The urea was added to the same amount of protein supplied by equivalent levels 0.5, 1.0 and 2.0 mg/mL of casein. In total, seven treatments were evaluated, including a control (only grass). The supplements were evaluated in a... |

| The aim of this work was to study the effect of carbon and nitrogen sources in submerged fermentation, and the casein effect on solid-state fermentation on rennin production by Mucor miehei. Biomass peaks reached 6.7; 8.1 and 8 g/L and enzymatic production peaks of 1,066; 857 and 480 Soxhlet Units (S.U.) for glucose concentration of 18; 25 and 35 g/L respectively. Flasks with baffles showed biomass peaks of 6.7; 8.3 and 10 g/L and enzyme activity peaks of 648; 279 and 300 S.U. for the same glucose concentration. The values of 923 and 667 S.U. were obtained when corn steep liquor and Proflo (Cottonseed Nutrients from Traders ®) were used. In SSF system the enzymatic activities were 414, 264 and 167 S.U., when using HCl 0.2 N, 0.3 N and 0.4 N respectively.... |

| Abstract: The casein and its hydrolysates have many desirable functional properties, so there is great interest in its use in food and pharmaceutical industries. The hydrolysis of casein by a new protease obtained from latex Jacaratia corumbensis was performed to obtain antimicrobial peptides. Four proteins were visualized by electrophoresis of the enzyme extract of J. corumbensis, a band of molecular weight of approximately 30 kDa with the presence of other bands of low density. The fractions as-CN, b-CN and k-CN, were subjected to hydrolysis for a period of 1 min 24 h, where aliquots were collected and analyzed by SDS-PAGE to the characterization of peptides. The hydrolysates were evaluated for antimicrobial activity by determining the Minimum Inhibitory... |

| The purpose of the study was to evaluate ostrich meat protein quality, as its consumption has significantly increased in the last few years in Brazil. Male Wistar rats were distributed in groupe of six elements. The standard group received a casein-based diet, the control group received a protein-free diet, and the experimental group received ostrich meat diet as protein source. The evaluated biological parameters were protein efficiency ratio (PER), net protein ratio (NPR), net protein utilization (NPU), and true digestibility (TD). There were differences (p<0.05) among treatment groups for all evaluated biological parameters. Mean true digestibility values were 92.12% and 75.77% for casein and ostrich meat, respectively. |

| The objective of this work was to evaluate the levels of sodium monensin on lactating cows and their effects on productive performance and milk protein fraction composition. It was used 12 Holstein cows, distributed in four balanced 3 × 3 Latin squares, and fed three diets: one control without monensin, and two diets with monensin at the levels of 24 or 48 mg/kg DM added to the concentrate. Milk production was daily measured throughout the entire experimental period. The samples used for analysis of milk composition were collected on two alternated days from the two daily milking. Non-protein nitrogen, total nitrogen and non-casein nitrogen contents were directly evaluated in the milk, and casein, whey protein and true protein contents were indirectly... |

| The objective of this study was to evaluate the potential of the A2 milk as an upgrading strategy for milk producers in Brazil. The primary data were obtained through semi-structured interviews with eight strategic actors of the A2 milk chain in September and October 2021. Five producers, two researchers and one member of the movements called the #bebamaisleite. The study was led by the theoretical framework of global value chain, focusing on the upgrading dimension. A2 milk is an upgrading opportunity for producers, following a global trend of food premiumization. However, caution is needed for producers to enter this chain because the market is incipient, the costs are significant, and the financial return is uncertain. Otherwise, there will be a... |

| Mozzarella cheese is traditionally prepared from bubaline (Bubalus bubalis) milk, but product adulteration occurs mainly by addition of or full substitution by bovine milk. The aim of this study was to show the usefulnes of molecular markers to identify the admixture of bovine milk to bubaline milk during the manufacturing process of mozzarella cheese. Samples of mozzarella cheese were produced by adding seven different concentrations of bovine milk: 0%, 1%, 2%, 5%, 8%, 12% and 100%. DNA extracted from somatic cells found in cheese were submitted to PCR-RFLP analysis of casein genes: α-s1-CN - CSN1S1 that encompasses 954 bp from exon VII to intron IX (Alu I and Hinf I), β-CN - CSN2 including 495 bp of exon VII (Hae III and Hinf I), and κ-CN - CSN3,... |
