Isomerization of Glucose to Fructose
In the previous paper, one of the authors described "A Survey on the Dextrose Industry in Japan and its Future" in the 1967 issue. As shown in the earlier paper, the supply and demand situation of starch in this country was drastically changed since 1963-64. In the later 1950's, the Japanese Government had a big problem to eliminate the big stock of the over-produced sweet potato starch. Theref...
متن کاملChemical, Functional, and Structural Properties of Spent Coffee Grounds and Coffee Silverskin
Spent coffee grounds (SCG) and coffee silverskin (CS) represent a great pollution hazard if discharged into the environment. Taking this fact into account, the purpose of this study was to evaluate the chemical composition, functional properties, and structural characteristics of these agroindustrial residues in order to identify the characteristics that allow their reutilization in industrial ...
متن کاملCharacterization of polysaccharides extracted from spent coffee grounds by alkali pretreatment.
Spent coffee grounds (SCG), obtained during the processing of coffee powder with hot water to make soluble coffee, are the main coffee industry residues and retain approximately seventy percent of the polysaccharides present in the roasted coffee beans. The purpose of this study was to extract polysaccharides from SCG by using an alkali pretreatment with sodium hydroxide at 25°C, and determine ...
متن کاملSpent Coffee Grounds as Adsorbents for Pesticide Paraquat Removal from its Aqueous Solutions
Spent coffee grounds were evaluated for adsorption efficiency in the removal of pesticide paraquat from its aqueous solutions. The influence of the adsorbent mass, agitation time, paraquat concentration and pH have been investigated in the batch sorption mode. Adsorption capacity (mg/g) has been found to be 27.87 ± 1.57 mg/g, while the removal efficiency has resulted of 32.25 ± 1.79 %. Adsorpti...
متن کاملDetermination of Kinetic Parameters for Catalytic Isomerization of Glucose to Fructose by immobilized Glucose Isomerase in an Aqueous-Ethanol Medium
Catalytic isomerization of glucose to fructose by immobilized glucose isomerase in an aqueous-ethanol medium was studied. Using Michaelis-Menten equation and Haldane relationship, the main kinetic parameters were determined: Kmf, Vmf, Kmr, Vmr. By comparing the aqueous-ethanol medium with an aqueous solution, the measured values of Kmr and Kmf were increased in the aqueous-ethanol solution, whi...
