摘要： PURPOSE:To obtain nearly white high-quality starch and protein, by grinding starch-containing subterranian stems in the presence of a specified additive while preventing the produced slurry and juice from darkening. CONSTITUTION:0.005-0.5wt.% at least one member selected from the group consisting of Na2S2O3, K2S2O3, NaHSO3, Na2SO3, and K2SO3 is added to starch- containing subterranian stems (e.g. potato), and the mixture is ground by means of a mixer to obtain a slurry. This slurry is separated into crude starch, pulp, and juice, and the crude starch is purified by water washing. The juice is heated at 55-85 deg.C for 0.5-100min to coagulate and deposit nearly white protein.

摘要： PURPOSE:To obtain high-purity fructose from glucose, by polymerizing a fructose-containing solution in the presence of inulase, separating fructose polymer from monosaccharides, hydrolyzing the fructose polymer with an acid. CONSTITUTION:A glucose-containing solution is brought into contact with glucose isomerase, glucose is partially converted into fructose, fructose in the solution is brought into contact with inulase (fructan hydrolase) to polymerize fructose. When concentration of fructose is high, a reaction in the reverse direction against fructan hydrolysis of normal reaction, namely, polymerization of fructose is advanced. A fructose polymer thus formed is separated from monosaccharides, and it is hydrolyzed with an acid, to give a high-purity fructose. Isomerization of glucose with glucose isomerase is coupled with fructose polymerization with inulase, and the fructose polymer can be directly obtained from glucose.

摘要： PURPOSE:To improve production efficiency of yeast, by regulating properly a feed of a substrate during cultivation. CONSTITUTION:A seed mold is put in the culture tank 1, a substrate is fed from the substrate tank 7 by the pump M to the tank, datum from the measuring device 5 for oxygen partial pressure at the inlet, the measuring device 6 for an amount of gas at the inlet, the measuring device 11 for oxygen partial pressure of gas at the outlet, the measuring device 12 for partial pressure of carbonic acid gas, and the measuring device for an amount of exhaust gas are treated to calculate RQ, and a flow feed velocity of substrate (alpha value) is changed. Formation of by-product is detected, and when substrate flow is minimum or zero, the signal of dissolved oxygen sensor 9 is detected by the dissolved oxygen meter 10, alpha value is changed depending upon the change of it, to regulate the flow feed velocity of substrate.

摘要： PURPOSE: To improve the yield in production of microorganisms, by controlling the concentrations of dissolved oxygen and carbon dioxide in a culture fluid to the target concentrations.
CONSTITUTION: In a controlling apparatus 5, signals for controlling at least one of the pressure and gas retention time in an apparatus 3 for preparing an oxygen-enriched gas based on signals of the oxygen concentration of a dissolved oxygen concentration sensor 9 are output, and signals for controlling at least one of the pressure and gas retention time in an apparatus 4 for removing carbon dioxide based on signals of the partial pressure of the carbon dioxide in a sensor 10 for the partial pressure of carbon dioxide are output. Thus, the partial pressure of oxygen in the oxygen-enriched gas prepared by adsorbing nitrogen in air is controlled, and the partial pressure of the carbon dioxide in the vapor phase in a cultivation tank 1 is controlled by controlling the concentrations of the dissolved oxygen and carbon dioxide in the culture fluid at the target concentrations. As a result, the yield of the product can be improved.
