Caracterização do óleo das sementes de Pachira aquatica Aublet para aproveitamento alimentar

Os frutos de Pachira aquatica Aublet apresentam sementes comestíveis com características organolépticas muito apreciadas pelas populações amazônicas, sendo pouco utilizados em outras regiões. Este trabalho teve como objetivo caracterizar as sementes quanto à composição centesimal e determinar as características físico-químicas e perfil de ácidos graxos. A determinação da composição centesimal das sementes (teores de umidade, lipídios, proteínas, cinzas e carboidratos) e análises do óleo extraído das mesmas (ácidos graxos livres, índices de peróxido, iodo, refração, saponificação, ponto de fusão e perfil de ácidos graxos) foram realizadas seguindo metodologia oficial. O teor de óleo nas sementes 38,39% demonstrou que estas têm potencial para aproveitamento industrial. Das características físico-químicas analisadas, o óleo extraído das sementes apresentou 39,2% de ácidos graxos livres (expresso em % ácido oleico), índice de iodo de 27,4 g I2.100 g-1, índice de saponificação de 208,0 mg.KOH g-1, índice de refração (40 °C) de 1,4569 e ponto de fusão de 41,9 °C. Quanto à composição de ácidos graxos do óleo predominaram os ácidos palmítico (44,93%), oleico (39,27%) e linoleico (11,35%). Tal fato favorece o uso deste óleo como matéria-prima para as indústrias alimentícia, farmacêutica e de cosméticos.

Use of homeopathic preparations in experimental studies with healthy plants

Background. The last comprehensive review of experimental research on effects of homeopathic treatments on plants was published in 1984, and lacked formal predefined criteria to assess study quality. Since then several new studies with more advanced methods have been published.Objectives: To compile a review of the literature on basic research in homeopathy with healthy plants with particular reference to studies investigating specific effects of homeopathic remedies.Methods: The literature search included English, French, German, Italian, Portuguese and Spanish publications from 1920 to April 2009, using predefined selection criteria. We included experiments with healthy whole plants, seeds, plant parts and cells. The outcomes had to be measured by established procedures and statistically evaluated. We developed a Manuscript Information Score (MIS) and included only publications which provided enough information for proper interpretation (MIS >= 5). A formallised Study Methods Evaluation Procedure (SMEP) was used to evaluate these studies, and the subgroup of studies with adequate controls to identify specific effects.Results: A total of 86 studies in 79 publications was identified, 43 studies included statistics, 29 had MIS >= 5, and 15 studies investigated the specificity of homeopathic preparations. Specific effects of decimal, centesimal and fifty millesimal potencies were found including dilution levels far beyond the Avogadro number. In consecutive series of potencies only some of the tested potencies showed effects. There were many individual studies with diverse methods and very few reproduction trials.Conclusions: Healthy plant models seem an useful approach to investigate basic research questions about the specificity of homeopathic preparations. More investigations with more advanced methods are recommended, especially in the sectors of potentisation techniques, effective potency levels and conditions for reproducibility. Systematic negative control experiments should become a routine procedure to control the stability of the experimental systems. Homeopathy (2009) 98, 228-243.

Salga seca e úmida de filés de pacu (piaractus mesopotamicus)

The goal of this study was to evaluate the process of salting and dry salting of fillets in pacu (P. mesopotamicus), from cultivation in cages. Fillet with skin were salted at a rate of 40% of salt in relation of the initial weight, for a period of 10 days. After processing, were evaluated for microbiological and centesimal composition of fillets subjected to salting and determining the concentration of sodium chloride (NaCl) and calculation of income. The centesimal composition were evaluated the protein, ether extract, moisture and ash of the raw material fresh and processed products by salting. The microbiological analysis included the determination of coliforms at 45 degrees C, Salmonella and Staphylococcus coagulase positive. The pacus subjected to umided and dry salting were within quality control standards established by the legislation. The content of umided, protein, lipids and chlorides showed differences (p< 0.05) between the processes of salt. However both forms can be used for the development of technological processes of low investment by encouraging new options for fish consumption.

Características de carcaça de cordeiros alimentados com grãos e subprodutos da canola

The aim of this work was to evaluate the introduction of 8% grains and by-products (meal or cake) of canola in the diets of lambs. To evaluate quantitative carcass characteristics, 24 Santa Ines lambs were used in a completely randomized design. Diets with averages of 15.4% of CP in DM and 80.2% of TDN were composed for 40% Tifton hay and 60% concentrate based on corn grain, soybean meal, whole grain canola, canola meal, canola cake and mineral mixture. The use of whole grains and by-products of canola in the diet of lambs finished in feedlot did not influence (p > 0.05) quantitative carcass characteristics. For cut dressing in relation to the CCW, no effect was observed for the analyzed variables among treatments. It was concluded that the introduction of grains and by-products of canola allow for satisfactory results, and could be recommended in the formulations of lamb diets.

Evaluating of the activity antioxidant and fatty acids profile of lychee seeds (Litchi chinensis SONN.)

Purpose: The purpose of this paper is to characterize lychee seeds regarding their centesimal composition, and also to evaluate their antioxidant potential and fatty acid profile. Design/methodology/approach: To obtain the extract, dehydrated and grinded seeds were extracted with ethyl alcohol for 30 min, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation, at room temperature. Afterwards, the mixture was filtered and the supernatant subjected to a rotoevaporator at 40oC aiming to determine, by direct weighing, the extract dry matter yield. Findings: The largest found values went to the total carbohydrates (72.75 percent). In the oil from the lychee seeds there was a high percentage of unsaturated fatty acids, the main component being linoleic, considered an essential fatty acid. Research limitations/implications: Implies the identification of compounds biativos extracted from seeds of tropical and subtropical fruits, and to prevent certain types of diseases. Originality/value: The article tries to identify new source of phenolic compounds extracted from fruit. © Emerald Group Publishing Limited.

Índice de acidez del aceite de pez en la nutrición de alevines de pacú Piaractus mesopotamicus

The aim of this study was to evaluate the effects of fish oil acidity on the growth of pacu (Piaractus mesopotamicus) juveniles. Two hundred juveniles with 10.53±0.65 g of weight and 8.74±0.13 cm of total length, were distributed in a totally randomized design in 20, 0.15 m3 meshmade tanks placed in a 25 m3 holding tank. Extruded commercial diets sprayed with soybean oil (control) with acidity index of 0.24 and fish oil with acidity index of 1.48, 6.40 and 9.85 were used. The fish were fed four times a day until apparent satiety. Productive performance, centesimal composition and blood biochemistry were analysed. At the end of the feeding period none of the analyzed parameters was affected by the use of acidified fish oil. Therefore, fish oil may be supplied to the pacu juveniles regardless of their pH.
