Development of sucrose test paper

Development of sucrose test paper. Suzuki, Takashi; Ohta, Takako (Coll. Educ., Yamagata Univ., Japan). 9031-76-9 and 9001-37-0 are also occured in this study. Iden, 40(8), 51-3 (Japanese) 1986. CODEN: IDENBZ. ISSN: 0387-0022. DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) A discussion is given for the principle and soaking soln. for prepn. of sucrose test paper (strip). An example of the soaking soln. contg. invertase, mutarotase, glucose oxidase, peroxidase, N,N-dimethylaniline, 4-aminoantipyrine, albumin, and poly(vinyl alc.) in 0.1M phosphate buffer (pH 5.6) is given. The test paper strip contg. the above components detect sucrose at a detection limit of 0.01% and showed excellent coloration for sucrose in the concn. range of 0.01-4%. .

Enzyme electrode for sucrose determination

Enzyme electrode for sucrose determination. (Matsushita Electric Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58216947 A2 16 Dec 1983 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: G01N027-30; G01N027-46.There are some reagents with their cas registry numbers 9001-57-4 and 9031-76-9 are used in this study. APPLICATION: JP 82-100213 10 Jun 1982. DOCUMENT TYPE: Patent CA Section: 9 (Biochemical Methods) Section cross-reference(s): 72, 80 A 2-layer electrode system for sucrose detn. is described. The 1st electrode is for H2O2 detection in sucrose detn. and consists of a thin Pt film-coated porous polycarbonate membrane in which glucose oxidase, mutarotase, and b-fructosidase are immobilized. The 2nd electrode is for eliminating interfering components, e.g., a- or b-glucose, and consists of a thin Pt film-coated porous membrane with immobilized glucose oxidase and mutarotase. These 2 electrodes are layered and attached to a plastic cylinder which contains buffer and ref. electrode. The 2nd electrode faces the sample soln. Thus, when a- or b-glucose is present in a sample, it is hydrolyzed by enzymes in the 2nd electrode and eliminated, and only sucrose reaches the 1st electrode at which H2O2 is produced after a series of enzyme reactions and detected by the Pt electrode. When ascorbic acid is present in a sample, it is oxidized at the 2nd Pt electrode. The current increase and the concn. of sucrose are linearly related. .
