• Some Properties of Starches of Lotus (<I>Nelumbo nucifera</I> Gaertn.) and Arrowhead (<I>Sagittaria turifolia</I> L.)

抄録

Some chemical and physical properties of lotus and arrowhead starches were investigated. The results obtained were as follows;<BR>1) The most popular sizes of lotus and arrowhead starches were 30-40 pm and 10-20 μm, respec- tively. The mean particle sizes of them were 32.7 μm and 14.5 μm, respectively.<BR>2) Susceptibility of arrowhead starch granules to hog pancreatin was similar to that of normal maize. Parcent degradation of lotus starch granules by hog pancreatin was approximately 50 % by 24 hour's reaction.<BR>3) By scanning electron microscopy (SEM), we could observe straited structures on the surface of lotus starch granules and layered internal structures of lotus, and arrowhead starch granules at-tacked by pancreatin.<BR>4) Amylose contents determined by the amperometric iodine-titration method were 21.0 % for lotus and 28. 7 % for arrowhead. Amylose contents determined by gel filtration of isoamylase-debranch-ed starches were 21.3% for lotus and 29.4% for arrowhead.<BR>5) The initiation temperature of gelatinization obtained by photopastegraphy were 53.5°C for lotus and 61°C for arrowhead. Onset temperature by differential scanning calorimetry (DSC) were 58.6°C for lotus and 67.4°C for arrowhead.<BR>6) By X-ray diffractometry lotus and arrowhead starches showed B-type and C_A-type patterns, respectively.<BR>7) The initial pasting temperature measured by Brabender's amylography (of 6 % starch samples) were 62°C for lotus and 70°C for arrowhead. The maximum viscosity (ηmax) of them were 958 B. U. for lotus and 640 B.U. for arrowhead and the break down were 768 B. U. for lotus and 200 B. U. for arrowhead.
