    There is a compelling argument that the number and intensity of disasters are increasing and will continue to do so for the foreseeable future. The causes are already evident. They include global climate change, increasing population density, human encroachment into disaster prone areas, recurrent famine, and the increasing intensity of weather events. Similarly, there is a general concern that the quality of the responses to these disasters is decreasing, particularly those causing the most damage. Recent examples include the Ebola epidemic, the Philippian tsunami, Hurricane Sandy, the Tibetan earthquake economic and famine refugee crises, and war-caused refugee situations around the world. Elements of the decrease in response quality include limited global logistics capacity, difficult inter-agency and/or international collaboration, and increased reliance on non-governmental organizations to provide the response. This essay is an appeal for more research on responder co-creation of and quality in the four broad phases of the disaster life cycle: mitigation, preparedness, response, and recovery

    Emulsifying properties of Maillard conjugates produced from sodium caseinate and locust bean gum

    Emulsifying properties of sodium caseinate -locust bean gum Maillard conjugates produced at different temperatures (54 - 96 ºC), protein/polysaccharide ratios (0.3 - 1.0) and reaction times (1 - 24 hours) were evaluated. Conjugate formation was confirmed by formation of color and high molecular weight fractions and the decrease of the αs- and β-casein bands. The emulsions stabilized by Maillard conjugates showed good stability. The mean droplet diameter (d32) tended to decrease with the increase of incubation time and temperature, except at extreme conditions (24 hours and 90 ºC or 96 ºC) when the partial degradation of the conjugates was probably favored, resulting in phase separation of emulsions. The emulsion viscosity decreased with the increase in the protein/polysaccharide ratio and with the degradation of the conjugates. The conditions used in the experimental design made the optimization of the conjugate production viable, which showed greater emulsifier properties than the pure protein under acid conditions.312429438CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP304611/ 2009-3 ; 473412/2009-82007/ 58017-
