AN ECONOMIC ANALYSIS OF INTERNATIONAL FEED AND MALTING BARLEY MARKETS: AN ECONOMETRIC SPATIAL OLIGOPOLISTIC APPROACH AgEcon
Schmitz, Troy G.; Koo, Won W..
A "hybrid" spatial price equilibrium model is developed to evaluate changes in production, consumption, and trade of feed and malting barley under alternative domestic and agricultural trade policy regimes. The analysis includes the economic welfare impacts of changes in various farm subsidy programs on the United States, Canada, Australia, and European Union (EU-15) which are the four major barley exporting countries in the world. The actions of competitive U.S. grain traders under the Export Enhancement Program cause feed barley exports to be segmented into two distinct markets. A spatial equilibrium is established in which the Canadian Wheat Board and Australian marketing boards behave as oligopolists in export markets under arbitrage conditions induced...

Mathematical drying kinetics modeling of jackfruit seeds (Artocarpus heterophyllus Lam.) Rev. Ciênc. Agron.
Leite,Daniela Dantas de Farias; Queiroz,Alexandre José de Melo; Figueirêdo,Rossana Maria Feitosa de; Lima,Leiliane Silva Lopes.
ABSTRACT Jackfruit (Artocarpus heterophyllus Lam.) is a fruit with pulp rich in carbohydrates, calcium, phosphorus, iron and B-complex vitamins. A large amount of waste is generated in the pulp processing, in which the seeds are included. Jackfruit seeds are often consumed after cooking, and may also undergo roasting, milling and incorporation into bakery products. The remaining jackfruit seeds can be germinated as a means to increase its utilization, constituting a process that confers positive biochemical modifications to the nutritional quality. Thus, the objective of this work was to dry the germinated seeds of the jackfruit tree in a convective drier at 55, 65 and 75 °C with drying air velocities of 1.0 and 1.3 m s-1, and adjusting different...

Chemical composition and functional properties of malted corn flours BABT
Grossmann,Maria Victória E.; Mandarino,José Marcos G.; Yabu,Márcia Cristina.
Flours with different physicochemical and functional properties were obtained from malted corn. Response surface methodology (RSM) was used to study the effects of malting time (1,3, 5 days), malting temperature (20, 25, 30º C) and gibberelic acid concentration (0.0; 0.5; 1.0 %) on these properties. The chemical composition and paste viscosity of flours were significantly affected by malting time and temperature, while water solubility index (WSI) and water absorption index (WAI) varied only with malting time. Gibberelic acid did not significantly influenced any of the studied properties. Germination at 20-25ºC for 3 days was recomended to obtain corn flour with high WAI, low viscosity and medium WSI, without excessive loss of proteins.

Production and characterization of amylases from Zea mays malt BABT
Biazus,Joana Paula Menezes; Souza,Roberto Rodrigues de; Márquez,Jesus Espinoza; Franco,Telma Teixeira; Santana,José Carlos Curvelo; Tambourgi,Elias Basile.
In this work the α and β-amylase enzymes were obtained from maize (Zea mays) malt and were biochemistry characterized. A germination study to obtain the maize malt with good amylase activity was made. The maize seeds were germinated in laboratory and the enzymatic activity was measured daily. Activity dependence to germination time were fitted to an exponential model (A=A0eµt), which showed that the behaviour of enzymatic activity in the germination process was similar to the growth of the microorganism. Its model could be applied to describe the mechanism of α-amylase production for each maize varieties and others cereals. Maize malt characterization showed that α and β-amylase had optimal pH between 4-6.5, optimal temperature 50 and 90ºC, and molecular...
