    Abstract: In starch degrading industry, the first step to be performed is gelatinization of starch granules at elevated temperature. This process tends to form a viscose suspension, thus making mixing and pumping a huge challenge. Therefore, to lower the viscosity of starch paste thermostable enzymes are added for breaking down the polysaccharides into oligo... Show More

    Abstract: Proteases are the most important class of industrial enzymes accounting for 60% of the global industrial enzyme market. Microorganisms are the major source of these enzymes. Production of hyrolysates from different protein sources is among the different application of proteases. Protein hydrolysates have a variety of food and non-food applications.... Show More

    Abstract: The purpose of this study was to determine the fungicidal action of liquid smoke generated from young coconut waste for infection of green rot (Penicillium digitatum) and blue rot (Penicillium italicum) pathogens in postharvest citrus fruit. The pyrolysis of 1 kg of young-coconut resulted in 409 mL of crude liquid smoke, and 300 mL of distilled liq... Show More
