  • Film Extrusion of Crambe Abyssinica/Wheat Gluten Blends
    Journal of visualized experiments : JoVE, 2017
    Co-Authors: Mikael Gällstedt, Henrik Pettersson, Therese Johansson, William R. Newson, Eva Johansson, Mikael S. Hedenqvist
    Abstract:

    Crambe Abyssinica is a plant with potential for use in industrial (non-food) plant oil production. The side stream from this oil production is a high-protein Crambe meal that has limited value, as it is not fit for food or feed use. However, it contains proteins that could potentially make it a suitable raw material for higher-value products. The purpose of this study was to find methods of making this side stream into extruded films, showing that products with a higher value can be produced. The study mainly considered the development of material compositions and methods of preparing and extruding the material. Wheat gluten was added as a supportive protein matrix material, together with glycerol as a plasticizer and urea as a denaturant. The extrudate was evaluated with respect to mechanical (tensile testing) and oxygen barrier properties, and the extrudate structure was revealed visually and by scanning electron microscopy. A denser, more homogeneous material had a lower oxygen transmission rate, higher strength, and higher extensibility. The most homogeneous films were made at an extruder die temperature of 125-130 °C. It is shown here that a film can be extruded with promising mechanical and oxygen barrier properties, the latter especially after a final compression molding step.

    Idesia (arica), 2013
    Co-Authors: Elias Terra Werner, José Carlos Lopes, Diego Gomes, Jaquelini Luber, Jose Augusto Teixeira Do Amaral
    Abstract:

    Este estudio tuvo como objetivo evaluar la eficacia de la prueba de envejecimiento acelerado, para determinar los efectos fisiologicos de semillas Crambe Abyssinica Hochst, un monton de dos cosechas (2009 y 2010). Se evaluaron: contenido de agua, la germinacion y el vigor por el indice de velocidad de la germinacion, envejecimiento acelerado a 41, 43 y 45 °C durante periodos de 24, 48, 72 y 96 horas, el peso fresco y el peso seco. El experimento se llevo a cabo en el esquema factorial 2x3x5 (mucha x temperatura x tiempo de exposicion), en un diseno completamente al azar, con cuatro repeticiones de 25 semillas. El peso fresco y peso seco no son eficientes para diferenciar la calidad fisiologica de las semillas de Crambe Abyssinica. Las influencias de envejecimiento acelerado, de manera similar, el porcentaje de germinacion y el vigor, con una mayor sensibilidad cuando las semillas son tratadas con temperaturas de 41 o 43 °C durante 72 h, lo que indica un papel prometedor para la estratificacion de la calidad fisiologica de la semilla Crambe de lotes con germinacion similar.

  • Influence of pre-germination treatments and temperature on the germination of Crambe seeds (Crambe Abyssinica Hochst) Influência de tratamentos pré-germinativos e de temperaturas na germinação de sementes de Crambe (Crambe Abyssinica Hochst)
    2012
    Co-Authors: Lima Deleon Martins, Felipe Pianna Costa, José Carlos Lopes, Wagner Nunes Rodrigues
    Abstract:

    AbstrAct The objective of this study was to evaluate the influence of pre-germination treatments and temperature on the germination of Crambe seed ( Crambe Abyssinica Hochst). The completely randomized design was used in a 3 x 3 x 2 factorial (physical treatments x chemical treatments x temperature). The chemical treatments consisted of paper soaked in gibberellic acid (GA 3 ), potassium nitrate (KNO 3 ) and water. The physical treatments consisted of maintaining the seed intact, mechanical scarification and seed coat removal. Temperatures of 25 and 30 oC were used in the completely randomized design. The variables studied were germination speed index, germination percentage, seed length and seedling dry mass. In the studied conditions, the percentage and rate of germination, length and seedling dry weight of seeds of C. Abyssinica Hochst were enhanced by removal of the integument, in soaking with GA 3 at 25 oC. Key words: gibberellic acid, potassium nitrate, seed tegument removal, scarification and temperatures.

  • LIGHT INFLUENCE ON SEED GERMINATION OF Crambe (Crambe Abyssinica Hochst.)
    Nucleus, 2011
    Co-Authors: Lima Deleon Martins, Felipe Pianna Costa, José Carlos Lopes
    Abstract:

    With current incentives to search for sources of renewable energy, the culture of Crambe (Crambe Abyssinica) before, basically, to forage production, has been widely cultivated in order to produce vegetable oil. However crop science information for this culture still prove to be scarce in the scientific community. However, due to be culture that has taken new directions lately, and it presents a promising potential for the production of vegetable oils, studies with greater demand for commitment, are studies related to seed quality, aiming at the sustainable planting. The aim of this study was to evaluate the effects of light on seed germination of Crambe Abyssinica. The statistical design used in the experiment was a completely randomized design with 2 treatments (absence or presence of light) and ten repetitions, totaling 20 experimental units. It is concluded that light is on promoting factor positive changes in seed germination of Crambe. In the presence of light seeds of Crambe showed higher percentages of normal seedlings and dry mass. Crambe seed was classified as neutral photoblastic.

  • frequencia de germinacao em sementes Crambe Crambe Abyssinica sob influencia de tratamentos pre germinativos e de temperaturas
    Nucleus, 2010
    Co-Authors: Felipe Pianna Costa, Lima Deleon Martins, José Carlos Lopes
    Abstract:

    O biodiesel figura como uma alternativa sustentavel ao petroleo e seus derivados, ja que sua producao e obtida de fontes renovaveis como plantas oleaginosas. A especie Crambe Abyssinica possui uma estrutura tegumentar denominada pericarpo. Em alguns casos, o pericarpo pode ocasionar elevada desuniformidade de germinacao em certas especies ou mesma ha ausencia de germinacao. Sendo assim, objetivou-se com o presente trabalho comparar frequencias de germinacao em sementes de Crambe sob influencia de tratamentos pre-germinativos e de temperaturas. O delineamento experimental utilizado para o experimentos foi o inteiramente casualisado, em esquema fatorial 3 x 3 x 2 (tratamentos pre-germinativos x tratamentos fisicos x temperatura), com 4 repeticoes de 25 sementes. Sendo os tratamentos: (3) tratamentos pre-germinativos: acido giberelico (GA3), nitrato de potassio (KNO3) e agua; (3) tratamentos fisicos: semente intacta, escarificada e sem tegumento; (2) temperatura: 25oC e 30oC. As sementes de Crambe descascadas apresentaram maiores frequencias de germinacao, em ambas as temperaturas e tratamentos quimicos.
