Wheat and cassava composite breads are generally associated with volume and textural defects in contrast with the traditional wheat based variants. Efforts to mitigate this challenge through use of synthetic additives have been unsuccessful owing to safety concerns. The objective of this study was to explore Grewia venusta mucilage as a potential natural additive in wheat-cassava composite bread production. Sweet cassava flour was used to replace wheat flour at 100: 0 (control), 90:10, 80:20 and 70:30% ratios in bread making. Aqueous extract of G. venusta stem bark was oven dried (50±3 oC), milled and added at 0, 1.0 and 2.0% (w/w) to the flour mixtures. These, along with other conventional inputs were mixed, and used to produce bread. Proximate compositions, physical and sensory properties of the bread loaves were evaluated. Cassava flour inclusion resulted in significant (P≤0.05) decrease in the protein content of the control from 18.1% to 12.1% (90:10%), 11.5% (80:20%) and 9.9% (70:30%). Addition of mucilage marginally increased the protein and dietary fibre contents of the loaves. Loaves containing 1-2% mucilage were more regular in shape with smoother crust than those without mucilage. Cassava flour addition at 10%, 20% and 30% decreased loaf height from 6.0 cm to 5.8 cm, 5.7 cm and 5.5 cm, as well as loaf volume from 815.5 cm3 to 783.1 cm3, 776.8 cm3 and 744.5 cm3, respectively. Mucilage inclusion resulted in increased heights and volumes of the loaves and reduced weights of loaf fragments upon slicing. The mucilage significantly improved the texture of the bread loaves.

The paper presents the results of using algae as a natural additive to chopped semi-finished meat products. The optimal ratio is set by means of the design method and the results of organoleptic assessment. The mathematical models that help to determine the optimal values of the factors and C, W and T (concentration of the components, moisture content and duration of mincing) are obtained.

<p>Objetivou-se monitorar o armazenamento dos biodieseis provenientes da transesterificação homogênea alcalina do óleo de soja e mamona via rota metílica, avaliando a indução oxidativa pela norma EN14112 e pelo método PetroOxy durante o período de 120 dias, também observou-se o comportamento dos biodieseis inseridos em blendas nas proporções de 20, 30, 40 e 50% v/v de biodiesel de mamona ao biodiesel de soja denominadas de M20, M30, M40 e M50 (em recipientes de aço-carbono fechado). Conforme análises físico-químicas, as especificações para ambos biodiesel e blendas satisfizeram as exigências dos limites permitidos pelo Regulamento Técnico nº 14/2012 da Agência Nacional do Petróleo, Gás Natural e Biocombustíveis. Exceção das análises de estabilidade oxidativa (M0, M20, M30 e M40), do índice de acidez após 60 dias (M50), após 90 dias (M40 e M50), após 120 dias (M100) e da viscosidade cinemática (M40, M50 e M100) que apresentaram valores fora dos limites estabelecidos pela norma. As propriedades fluidodinâmicas apresentaram comportamentos semelhantes para os biodieseis metílicos e blendas, assim, nestas concentrações o biodiesel metílico de mamona atua como um aditivo natural ao biodiesel metílico de soja. Através do método EN 14112 verificou-se que a blenda M50 é mais resistente ao processo de oxidação durante armazenamento de 120 dias.<strong></strong></p><p align="center"><strong><em>Quality of biodiesel soy, castor beans and blends during storage</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The objective of the study was to monitor the storage of biodiesels from alkaline homogeneous transesterification of soybean and castor oil via methyl route, and to evaluate the oxidative induction by the EN14112 standard and the PetroOxy method over the period of 120 days. We observed the behavior of the inserted biodiesels in blends in the ratios of 20, 30, 40 and 50% v / v biodiesel from castor beans of soybean biodiesel named M20, M30, M40 and M50 (closed carbon steel containers) . As physical and chemical analysis, specifications for both biodiesel and blends met the requirements of the limits allowed by the Technical Regulation No. 14/2012 of the National Agency of Petroleum (ANP). Exception of the oxidative stability analysis (M0, M20, M30 and M40), the acid value after 60 days (M50), after 90 days (M40 and M50), 120 days (M100) and kinematic viscosity (M40, M50 and M100) with values outside the limits established by the standard. The fluid-dynamic properties show similar behavior for blends methyl biodiesels and thus these concentrations methyl castor biodiesel acts as a natural additive to the methyl soybean biodiesel. By the method EN 14112 was found that M50 blend is more resistant to oxidation during storage process 120 days.</p>

Abstract The aim of this study is to analyze the effect of natural additive incorporation on processing nanocomposites and their effect on the functional characteristics of nanocomposites such as water uptake characteristics, drug adsorption and dissolution behaviors. Chitosan and montmorillonite were processed with olive oil and glycerin natural additives. In order to compare the processing results, the structure and the morphology of the polymer nanocomposites were examined by using infrared spectra, X-ray diffractograms and electron microscope images. Processing with nontoxic and healthful olive oil as a hydrophobizing agent overcame the high water uptake properties of the polymer nanocomposites and eliminated the use of other expensive chemicals. The nanocomposites without additives adsorbed the highest amounts of methylene blue at equilibrium. In vitamin B12 dissolution studies, not only the additives but also the reinforcement affected the results. Obviously, it can be seen that both the natural additive types and the reinforcement modification effects governed the drug adsorption and dissolution behaviors of the new tailored polymer nanocomposites. Moreover, the additives also improved the processing and handling abilities of these polymer nanocomposites. According to the results, these nanocomposites are promising candidates for medical applications like as a carrier for drug delivery and for skin treatment studies.
