    摘要： Disclosed are a novel fructosylamine deglycase characterized by the specificity to amadori compounds of catalyzing oxidation of the compounds to produce an .alpha.-ketoaldehyde, an amine derivative and hydrogen peroxide; a method of producing the novel enzyme by cultivating microorganisms belonging to the genus Candida and having an ability of producing the novel enzyme; and a method of quantitative determination of amadori compounds by applying the novel enzyme to a sample containing amadori compounds to measure the amount of the hydrogen peroxide to be formed by the oxidation reaction or measure the amount of the oxygen to be consumed by the reaction to thereby obtain the amount of the amadori compounds from the measured value. The invention provides a novel enzyme characterized by the high specificity to the reaction with amadori compounds, especially that having therein a saccharide moiety as bonded to the .epsilon.-amino group, and also provides a method of producing the enzyme and a method of quantitative determination of amadori compounds with the enzyme. Using the enzyme, quantitative determination of amadori compounds, which is difficult by conventional enzymatic methods, is possible with ease. In particular, in measurement of the amount of a saccharified protein in a sample from a living body, which is an important index substance in diagnosis of diabetes, the enzymatic method of the invention of measuring fructosamine in the sample is hardly influenced by other interfering substances or impurities in the sample, the influence by them having been inevitable in conventional chemical methods. Accurate determination of the amount is possible by the method, and the method is free from the inconvenience of staining the kits and instruments used. For measuring glycohemoglobin, the method displays another characteristic feature that its operation is more simple and needs less labor and time than conventional methods.

    摘要： A variety of plant diseases and damage by certain pests in agricultural and horticultural plants can be efficiently controlled without substantial chemical injuries by applying a plant-protecting composition which comprises (a) 1 part by weight of a chitosan hydrolyzate having an average molecular weight of 10,000 to 50,000, obtained by acid hydrolysis or enzymatic hydrolysis of chitosan and (b) 0.25 to 4 parts by weight of acetic acid. Any possible chemical injury to plants caused by applying the composition can be further reduced when the composition is admixed with a deproteinized juice of alfalfa leaves.

    摘要： A process for producing starch noodles, which comprises adding 45-55 parts by weight of hot water to 100 parts by weight of starch obtained from at least one member-selected from the group consisting of potato, sweet potato, tapioca, corn, wheat and a product thereof followed by being mixed to prepare large particles of dough and then extruding the dough under degassing at degrees of vacuum of not less than 650 Torr to produce a dough sheet. Starch noodles can be produced efficiently in simple procedures without separately preparing starch paste and without using special rollers. Further, starch noodles thus produced are highly transparent and less melted by boiling.
