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.

Efeito da utilização de substitutos de gordura em queijos light

Cheeses are known to be sources of calcium, phosphorus and protein, important nutrients for a suitable nutrition. However, certain cheeses imply the ingestion of large amounts of fats, which can cause the development of coronary heart and carcinogenic diseases. Although consumers are aware of the necessity of reducing the fats intake, they are still not pleased with the quality of light cheeses available on the market, because the partial or total fat removal provides some undesirable changes, especially regarding to the product texture and flavor. In order to offer products nutritionally adequate and palatable, alternatives have been developed to improve the characteristics of light cheeses. Such alternatives include the use of fat substitutes, those additives that improve the functional and sensory characteristics of cheeses with reduced fat. Fat substitutes composed of proteins, carbohydrates and lipids, or a combination of them, help the retention of moisture and eliminate the undesirable characteristics of fat reduced-cheeses. In this context, this review aims at reporting the innovations and trends on the use of fat substitutes to produce light cheeses.

Avaliação da qualidade de óleos de fritura utilizados em restaurante universitário

Frying is a widely used method of preparing food, because it is a very fast and convenient process, and because it provides specific characteristics of color, flavor, odor, and texture, besides having great consumer acceptance. Therefore, the interest in the physiological effects that oils heated at high temperatures can cause to the human body arises. The aim of this work was to analyze the levels of frying used oil alteration in different kinds of foods served at the university restaurant at “Instituto de Biociências, Letras e Ciências Exatas” (IBILCE), in São José do Rio Preto-SP. In addition, it aims to make the restaurant aware of the good ways to fry and the commitment of providing good quality food to students and professionals of the Institute. With this purpose, determination of total polar compounds, conjugated dienoic acids, peroxide value, and fatty acid profile were analyzed. Two rapid tests were also used: 3M Fat Monitor and Oil Test kit. The results were compared with limits recommended for the disposal of oils and fats used in frying by the Brazilian Health Surveillance Agency (ANVISA), by other countries, and by other researches. Thus, it was concluded that the university restaurant provides the consumers with fried food of good quality, since none of the analyses showed results above recommended, although there is a need of improvement in the quality control of the oil used, in order to avoid unnecessary costs to the university restaurant.

Do politicamente correto ao incorretamente polido

The text argues that a linguistic analysis paired with the appreciation of the context of current social stands is highly legitimate, observing, however, that, in different situations, this so-called investigative-appreciative attitude has been transformed in actions and reactions that might become vulgarized in common place, or might even become disfigured in stupidity. The distortions in the assessment of the discourse of the other are now a widespread, the hunt for what is now conventionalized as the politically incorrect in language is just a sample of such a distortion. In this presentation, a number of cases of such a nature is analyzed against cases in which, inversely, the use of language is markedly polite, but the deviation of conduct is made more evident. The objective is to evaluate both cases via the role of intersubjectivity in the construal of discourse, aiming at verifying its conceptual counterpart, with special attention to evidence on the mutual conceptual engagement between interlocutors.

Avaliação sensorial e influência do tratamento térmico no teor de ácido ascórbico de sorvete de pimenta

In this work were prepared with three ice cream added peppers of different varieties: Capsicum baccatum, Capsicum annuum and Capsicum frutescens. The peppers were first pasteurized and evaluated in relation to the effect of heat treatment on the ascorbic acid content. Results showed that the Capsicum annuum showed higher ascorbic acid content, but the heat treatment resulted in greater loss of biocompounds. The higher retention of ascorbic acid was observed with Capsicum frutescens, which presented lower content of biocompound, but near of the pepper Capsicum annuum. The follow attributes was performed to evaluate the acceptance of ice cream through the sensory attributes: color, aroma, flavor and texture. Analysis of variance showed no significant difference between ice cream formulations at the 5% level of significance with regard to color, aroma and texture. Regarding taste, the samples differed significantly, at 5% significance, and the most preferred was the ice cream made with pepper Capsicum frutescens.

Microbial, physical, chemical and sensory properties of Minas Frescal Cheese with inulin and acacia gum

Minas frescal cheese is a semi-skimmed product with high moisture and simple preparation and one of the most consumed in Brazil. Thus, the aim of this study was to combine the characteristics of inulin and gum acacia (by having fibers and being prebiotic) to produce a minas frescal cheese. Were evaluate the characteristics physical and chemical, microbial and sensory acceptance (hedonic scale) of each cheese. Three cheeses were prepared; one as a standard (QP) without inulin, and others with 0.49% (QI25) and 0.98% (QI50) inulin, the amount of gum acacia was maintained. The yield of the formulations with gum acacia and inulin were 9.76% for (QI25) and to 20.03% (QI50) higher than the standard sample. In relation to moisture content, samples containing inulin and gum acacia showed values greater than the standard sample. The sensory analysis indicated no differences between scores for color, aroma and texture, but significant differences were detected for flavor, in which (QI25) received the highest acceptance. Regarding the energy value, it was obtained 276 kcal (QP), 215 kcal (QI25) and 190 kcal (QI50). Therefore, the developed product presents satisfactory results for sensory, microbiological and physical- chemical analyses.

Desenvolvimento e avaliação físico-química, sensorial e da estabilidade de ácido ascórbico de doce de leite com pimenta

The dulce de leche or milk candy is a food widely consumed in Brazil, which shows typical characteristics of taste, color, flavor and texture. The lady-finger red pepper is regularly present on the Brazilian people table as this product contains a pungent flavor favoring various spices; and it is also rich in ascorbic acid (vitamin C) which is an excellent antioxidant. This study aimed at developing a dulce de leche containing lady-finger red pepper, and to determine the composition of the product. Also, the ascorbic acid contents were quantified in products stored for different periods (0, 30 and 60 days). The product acceptance by consumers on the sensory characteristics was evaluated by means of hedonic scale for color, aroma, flavor and texture attributes. The composition of the product was in accordance with the legislation in force, and the ascorbic acid contents were practically stable during the storage, and the sensory analyses indicated that the red pepper-containing dulce de leche was well accepted.
