Abstract

Starch is eaten after heating,but heating gives a morphological variation to it-the
expansion. The variation of the expansion is influenced by the annexes -the seasonings.
This experiment is a morphological observation of the variations of heated starch granules by annexing common salt, saccharose,and acetic acid which are very often used in cooking starch. Part 1 is the results of the study of the starch granules derived from potatoes (Solanum tuberosum), sweet potatoes (Ipomoea batatas),corn (Zea mays) and wheat (Triticum aeslivum),but Part 2 is the results of the study of the starch granules derived from the subterranean stems of Yoshinokazura (Pueraria Thunbergiana Benth),Indian
lotus (Nelumbo nucifera),Chinese yam (Dioscorea japonicum) and so on,and from the seeds of buckwheat (Phagopyrum esculentum).
All the starch granules used for the observation were derived from the natural plants from Hiroshima Prefecture by triturating them according to the established method,passing them through a 120-mesh metal sieve,removing grease and protein from them,suspending them in the water,centrifugalizing them (3,000 r.p.m. 5 min.), and drying the precipitates.
To these starch granules there were added NaCl solution,saccharose solution and acetic acid solution with al1 sorts of thickness,and they were heated at 100 degrees for a limited hour. And then they were dyed with iodin potassium iodide solution,embedded with glycerin,and observed through the optical microscope.
It may safely be said that there is a certain direction in the process of making paste from the starch granules. In the case of heated starch granules without the annexes some sorts of annexes control their expansion. There is every indication that a greater deal of annex controles their expansion more effectively. Above a11,when the acetic acid solution is annexed to them,a greater deal of amylose gushes out,and the acid promotes the hydrolysis and breaks them down. These results are much the same as Part 1.
