Caracterização físico-química, reológica e sensorial de iogurte obtido pela mistura dos leites bubalino e caprino

Milk from different animals can be used for dairy production. Yoghurt is a popular fermented milk product and considered to be one of the greatest importance in terms of consumer acceptance and consumption. The present research deals with the production of strawberry set-type yoghurt by mixing goat and buffalo s milk and it has the objective of taking advantage of the intrinsic characteristics of each milk to produce a final product with desirable attributes. It was conducted by analyzing five experimental groups with different proportions of goat and buffalo s milk: C 100% goat s milk; 7C3B - 70% goat s milk and 30% buffalo s milk, 5C5B - 50% goat s milk and 50% buffalo s milk, 3C7B 30% goat s milk and 70% buffalo s milk; B - 100% buffalo s milk. Each group was evaluated for total solids content and the acidification profile was monitored every 30 minutes by pH analysis. The yoghurt samples were analyzed for physical-chemical (pH, acidity, protein, fat, total and reducing sugars, ash and total solids), rheological (syneresis and viscosity) and sensory characteristics (appearance, odor, consistency and flavour). Samples with higher percentual of bubaline milk reached Vm faster, but the time necessary for pH 4.6 (Te) were similar between groups. Statistical differences (p<0.05) were observed for fat and total solids content of yoghurt, with superior values for groups higher proportions of buffalo s milk. The parameters of behavior reached by the model of Ostwald of Waale pointed yoghurt samples as non-Newtonian and pseudoplastic fluids. Yoghurt made only with goat s milk (C) had higher values (p<0.05) for syneresis, which can be explained by its fragile coagulum. Additionally, this group also had the lowest sensory scores for the attributes consistence and taste, while bubaline yoghurt (B) obtained the best acceptance indexes for all of the appraised parameters

Studying the distribution of Selenium in buffalo and cow's milk whey

Neste estudo, a cromatografia por exclusão de tamanho (SEC) com detecção online ultravioleta (UV), espectrometria de absorção atômica em forno de grafite (GF AAS) e a espectrometria de massa por tempo de voo com dessorção/ionização de matriz assistida por laser (MALDI-TOF-MS) foram usadas para estudar a associação de selênio com macromoléculas e compostos presentes no soro de leite de búfala e bovino. Os perfis de SEC-UV obtidos para as amostras de soro de leite de búfala e soro de leite bovino indicaram a presença de espécies de alta e baixa massa molecular. A combinação das informações obtidas com SEC-UV, GF AAS e MALDI-TOF-MS para as frações < 10 kDa confirmou a associação de selênio com espécies de baixa massa molecular.

Histórico e aspectos tecnológicos do processamento da linguiça cuiabana

This paper reports the data on the cuiabana sausage historical aspect, and from the study performed on its technical/sensory characteristics. Four formulations of cuiabana-type sausage were prepared, varying the basic raw material (bovine, chicken and swine meats). For processing these sausages, the raw meats (beef, chicken and pork) were cut into cubes and together with the other ingredients (garlic, cheese, pepper and chives) they were weighed and homogenized. The resulting mixture was refrigerated for 24 hours for intensifying the flavor. Thereafter, it was stuffed into natural casings. These prepared samples were characterized on the physical-chemical profile and on the shelf life under refrigeration for over a seven day-storage in order to assess the microbiological contamination (total coliforms and fecal thermotolerant bacteria), sulphite-reducing clostridium, Salmonella spp., coagulase-positive Staphylococcus), and pH. The sensory evaluation and statistics analysis were carried out on the different types of laboratory- processed cuiabana sausage. Introducing over time changes in the cuiabana sausages formulation are positive factors; therefore, variations in the formulations it is feasible to get a better final product than that original one, and it might be resulted from the market demand.

Milk composition of Murrah buffalo cows supplemented with cupuassu byproduct in Western Amazon.

The aim of this study was to evaluate milk composition of Murrah buffalo cows supplemented with rations containing cupuassu byproduct in substitution of ground corn. Isoprotein and isoenergy rations were balanced with 22.0% of crude protein (CP) and 80.1% of total digestible nutrient (TDN).

Características físico-qímicas da carne de caprinos submetidos a diferentes níveis de substituição do leite por soro de queijo durante o aleitamento

Fifty six crossbred kids Parda Alpina x Gurgueia were separeted into four groups of 14 (seven male and seven female) and submited to four treatments with different levels of milk goat substitution by cheese serum. The treatments were : T1=milk goat (testify); T2=15% serum at 23 days and 33% at 55 days; T3=15% serum starting from 16 days, 33% on 23 days and 51% on 72 days of age; and T4=33% on 16 days and 69% of liquid diet in the final fase. At 92 days of age, all animals were slaughtered for carcass evaluation. Pallete were separeted from 20 male animals (five by treatment) and the physical and chemical analysis of the meat were realized using these materials. The studied characteristics were: total weight (TW), meat weight (MW), bone weigth (BW) of the pallete, and percentage of umidity (U), ashes (A), protein (P), fat (F) and pH of the pallete meat. There was significant effect of the treatment over F. Means of PW, A and BW were, respectively 491, 342 and 149.8 g. The meal represented 69,6% of total pallete weight. Means of U, A, P and F were 73, 1.0, 19 and 1.95%, respectively. The pH was 6.7. Results allow to conclude that only the fat percentage of the meat was modified, due to the administration of serun milk on the liquid diet of the kids, during the milking fase.

Aspectos físico-químicos e microbianos do queijo maturado por mofo obtido da coagulação mista com leite de cabra congelado e coalhada congelada

Milk goats are indicated as an economic alternative for small farmers and cheese making could improve their profits. Goat's milk has a seasonal production characteristic and shows periods of abundance and others of scarcity. The use of frozen milk or frozen curd to make cheese can be used to solve the problem. The aim of this work was to evaluate the preparation of cheese made from mixed curd and ripened by Penicillium candidum mould using slow frozen milk (in a domestic freezer) or fast frozen milk (by liquid nitrogen). The slow frozen curd and fast frozen curd without whey were used. It was observed that the cheese from the slow and fast frozen milk and from the slow and fast frozen curd did not differ from the control cheese for the yield, chemicophysical characteristics, chemical composition, extention ripened rate, depth ripened rate and microbiological aspects, even when it was expressed as a dry matter content of cheeses.
