O trabalho teve o objetivo de desenvolver uma linha de preparações cosméticas baseada no estudo das matérias-primas, na análise sensorial do produto e no mercado atual. A linha desenvolvida recebeu o nome de Bella Fiore. Essa linha é composta por produtos destinados ao uso capilar, banho e corporal. Foram desenvolvidos 10 produtos, sendo eles, três xampus, três condicionadores, uma máscara capilar, um sabonete líquido, um óleo para banho e um hidratante corporal.

This study aimed to produce beer, using different botanical origins of honeys (orange, eucalyptus and wild), as malt adjuncts, and their Physical-chemical and sensorial characterizations. The production was made with malt, water, hops and honey. All musts were adjusted to 12 Brix, and the concentration of honey in the formulation was 45% (based on the extract), except for the control (0%). The physical and chemical analysis were performed on malt (extract content), honey (pH, free acidity, lactonic acidity, total acidity, color, turbidity, extract content, moisture content, reducing sugar, total reducing sugar and sucrose) in wort (content extract, pH, color, turbidity, fermentability ,bitterness and total acidity) and beer apparent extract, apparent fermentability, real extract, real fermentability, alcohol content, pH, total acidity, total foam, foam density , bitterness, carbon dioxide, color and turbidity). Sensory analysis was performed by nine-points hedonic scale testing. The attributes evaluated were appearance, aroma, flavor and overall. The results were submitted to ANOVA and means compared by Tukey testing at a 5% of probability. Beer with honey as adjuncts’ had high fermentability and low content of fat, compared to the pure malt beer. The addition of honey as an adjunct did not affect the majority of the physical-chemical parameters, except for turbidity, whereas beer with honey showed the highest value for this feature, in addition, it has also presented their biterness differences the values for beer with honey were lower. The different types of honeys did not affect the acceptability of beer, however, the beer with honey showed greater acceptance between beer with malt and honey

A cachaça é uma bebida exclusivamente brasileira que vem conquistando espaço no mercado dentre as bebidas alcoólicas destiladas. Porém, o Brasil é responsável pelo consumo de 99% do total produzido por ano e apenas 1% é exportado. Isso se deve à falta de padronização na produção e de conhecimento por parte dos produtores, que levam a contaminação por compostos indesejáveis produzindo uma bebida de baixa qualidade, tanto físico-química quanto sensorialmente. Os métodos de redestilação e filtração em carvão ativado vêm sendo alternativas para melhoria da qualidade. Amostras de cachaças foram submetidas a esses métodos e avaliadas quanto à composição química e a qualidade sensorial. As análises químicas de acidez volátil, aldeídos, ésteres, metanol, álcoois superiores e carbamato de etila foram realizadas em triplicatas utilizando cromatografia gasosa. Para a análise sensorial, as amostras foram submetidas ao Teste de Aceitação utilizando escala hedônica híbrida de nove pontos e avaliadas pelo Teste de Kruskal-Wallis. Foi aplicado também o Teste de Ordenação para avaliar a preferência entre as amostras e a Intenção de Compra foi avaliada utilizando-se uma escala de cinco pontos, de certamente não compraria a certamente compraria. A redestilação reduziu os níveis de acidez volátil, cobre e carbamato de etila enquanto a filtração diminuiu as concentrações de aldeídos e ésteres. Os processos de redestilação e filtração em carvão ativado não alteraram a aceitação da bebida, mantendo seu perfil sensorial e melhoraram a composição química.

In this work evaluated the content of vitamin C and total carotenoid in tomatoes fresh and dehydrated for conserve, with posterior immersion in sauce, verifying its sensorial acceptability. Dehydration was performed in dryer with airflow at 70 °C to obtain a product with final moisture of 45%. Determinations were carried out ascorbic acid, soluble solids, acidity, sugars and carotenoid before and after the dehydration process. The dehydrated tomatoes had been immersed in three types of sauces (pepper sauce, oregano with parrot leaves sauce and garlic sauce) per 25 days. After this period, the dry tomatoes in conserve had been submitted to the sensorial analysis in the pate form, applying themselves preference test. The results had been showed that retention of vitamin C and total carotenoid in the dehydrated product showed retention of 14.0% and 44.3%, respectively, in tomatoes after the dehydration process. Among the formulation of canned t

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.

This article aims to disseminate the results of a university action which occurred through the Extension Course entitled Management and Health at Work, conducted from March to September 2011 and offered by “Coordenadoria de Saúde e Segurança do Trabalhador e Sustentabilidade Ambiental” (a kind of Workers' health and safety and environmental sustainability agency) - an agency managed by “Pró-Reitoria de Administração - PRAd/Unesp”. This action had the audience of the technical and administrative staff of the several Institutes (Units) of UNESP in positions of Leadership and Supervision. The course was proposed to equip managers to deal with issues related to health and safety at work in daily labor. Six hundred managers of all UNESP Institutes participated in the course. The meetings were logistically designed respecting the proximity of the participants’ Institutes. The methodology adopted was based on qualitative techniques such as group discussion, role-plays, analysis of film, reading and discussing texts, together with the preparation of a proposal for health promotion by the participants. As a result it was considered that the course offered a convenient and timely opportunity to reflect on and discuss the theme of health and safety at UNESP, as well as to make leaders and managers effective agents to implement programs of disease prevention and health promotion at work.
