Caracterização química e legalidade em bebidas não alcoólicas de maçã

Apple is a fruit that offers promising prospect for industrialization as it has favorable characteristics for this purpose and can obtain products with good acceptance. In Brazil, approximately 15% of the production is processed into juice, and a portion is exported. Among the fresh fruit and juice, apple adds US$ 30 million annually to the Brazilian foreign exchange earnings. The aim of this study was to characterize, using chemical analysis, concentrated juices, commercial apple juice, nectar, and soft drink. In addition, to compare them with their respective Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Concentrated juices and commercial beverages were analyzed in triplicate for soluble solids content (Brix), pH, total acidity (AT), and ratio. In concentrated juices, the Total Sugar Reducer (ART) was also assessed. The results obtained in the laboratory were compared with the PIQ and Codex Alimentarius to verify compliance with applicable regulations. Seven concentrate juices, five juices, six nectars, and three apple-flavoured soft drinks were analyzed. The Brix of pulpy and clarified concentrated juices were, respectively, 71.16±1.29 and 40.40±0.57°Brix. In all concentrated juices, the Brix was in accordance with Codex Alimentarius. The Brix and AT in sweetened clarified juices were 11.50±0.14°Brix and 0.18±0.04g of malic acid/100g sample. In pulpy whole juices the values ​​were 11.20±0.70°Brix and 0.30±0.06g of malic acid/100g sample. The values of Brix and AT in apple-flavoured soft drinks were 11.03±0.93°Brix and 0.18±0.04g of malic acid/100ml sample. Commercial juices and soft drinks also presented °Brix and AT in accord with the PIQ established by MAPA. The apple nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius. The definition of the PIQ is an important tool for quality control of beverages manufacture in Brazil. Therefore, it is recommended for the control agencies to define the parameters that are not established.

Processamento da amostra das silagens de grãos úmidos de sorgo com baixo e alto tanino na determinação da digestibilidade aparente em equinos

There were used four castrated male horses, crossbred. It was used randomized block by design for four replications. The objective was to evaluate the effect of using samples, ground or in natura, in the precision of the mobile nylon bag technique (MNBT) in comparison to the total collection (CT) method in oder to estimate the apparent digestibility coefficient (DC) of nutrients of high-moisture grains silage of sorghum with low (SSLT) and high (SSHT) tannin in the feeding equine. No effect was observed for MNBT and CT methods with in natura sample for DC of DM, OM, CE, CP to SSLT (P>0.05), whose average values were 81.71, 84.23, 82.27 e 81.43%, respectively. The MNBT did not showacuracy to evaluate of DC of the SSHT, with ground and in natura samples. It was concluded that MNBT containing in natura sample should be used to determinating the DC of SSLT to DM, OM, CE and CP for equines.

Determinação do teor de glicose em bagaço de cana-de-açúcar hidrolizado pelo processo de conversão enzimática

The production of ethanol and sugar from sugarcane juice generate as byproduct, the bagasse. Currently, the bagasse, an industrial lignocellulosic biomass, can be used for production of second-generation ethanol, since when it is submitted to hydrolytic processes generates fermentable sugars. The objective of this study was to produce fungal enzymes capable of hydrolyzing this lignocellulosic biomass to generate glucose. For this, we used the mushroom species Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, and Pycnoporus sanguineus as potential sources of laccase, manganese peroxidase and lignin peroxidase enzymes, capable of hydrolyzing the crushed sugarcane. The hydrolysis process was performed with the highest enzymatic activities observed from laccase in L. edodes (39.23 U-mL after 25 day incubation), P. ostreatus (2.5 U U-mL after 27 day incubation), P. sanguineus (80 U-mL after 27 days of incubation) and P. eryngii (16.45 U-mL 15 days incubation). MnP and LiP showed no significant results. The enzymatic hydrolysis of sugarcane bagasse in natura (32,17% hemicellulose, cellulose 52,45% and 10,62% lignin) and bagasse hydrolyzate with 7,0% H2SO4 (0,20% hemicellulose, 68,82% to 25,33% cellulose and lignin) were evaluated for each enzymatic obtained. Compared to others, the enzymes produced by P. sanguineus incubated in sugarcane bagasse showed better efficiency resulting in glucose with an average content of 0,14 g-L. Although the levels of glucose determined in this work were low in relation to the literature, it can be stated that the laccase, manganese peroxidase and lignin peroxidase enzymes demonstrated good hydrolytic potential, especially those produced by the fungus P. sanguineus.

Composição bromatológica, consumo e digestibilidade in vivo de dietas com diferentes níveis de feno de catingueira (Caesalpinea bracteosa), fornecidas para ovinos Morada Nova

Com objetivo de determinar o consumo e a digestibilidade in vivo, bem como a composição química de dietas com níveis crescentes (0, 50 e 100%) de feno de catingueira (FC), utilizaram-se 15 ovinos Morada Nova, durante um período de 22 dias. Foi usado delineamento inteiramente casualizado com três tratamentos e cinco repetições. O FC apresentou 91,5% de matéria seca (MS), 93,89% de matéria orgânica (MO), 11,25% de proteína (PB), 4,31% de extrato etéreo (EE), 45,47% de fibra em detergente neutro (FDN), 37,08% de fibra em detergente ácido (FDA), 8,39% de hemicelulose (HE), 24,37% de celulose (CE), 12,52% de lignina e 6,30% de tanino condensado. Os consumos de MO e MS, em g/dia, g/kg0,75 e %PV; energia bruta (EB), em kcal/kg/dia e kcal/kg0,75; e dos componentes da parede celular foram reduzidos linearmente pelo aumento de FC na dieta. Os consumos de PB, proteína digestível (PD) e EE aumentaram linearmente com o aumento do FC na dieta. Os coeficientes de digestibilidade da MS, MO, PB e EB das dietas não foram afetados pela inclusão do FC. No entanto, observou-se redução linear para os coeficientes de digestibilidade da FDN, FDA, CE e EE e efeito quadrático para o coeficiente de digestibilidade da HE. Os consumos médios de MS e PB verificados nos níveis intermediários de FC atenderam as exigências de mantença dos animais.

O uso corporativo do território brasileiro no período técnico-científico-informacional: o circuito espacial produtivo e círculos de cooperação da empresa Natura

In the current historical period marked by globalization and neoliberal policies have seen the pursuit of expanded reproduction of capital by corporations, which make from the deepening territorial division of labor, ie, the increasing presence of its circuit productive space within steps towards the relations between capital and labor. This capital increase is made possible mainly by exploiting precarious forms of labor. In Brazil today, much of the population enjoys the possibilities of consumption, due mainly to the policy measures implemented in the last decade, this situation favors further expansion of large companies in our territory, thus the circuit analysis of spatial production of cosmetics contributes to a political debate about the uses of the national territory. Given that companies are organizations whose actions occur inseparably technical systems that make up the territory, this course conclusion work seeks to understand the circuit of production space and cooperation circles cosmetics company Natura Cosmetics S/A
