Japanese chestnuts are known to have pellicle difficult to peel off. To make the task easier at home and in commercial processing, some methods of pretreatment have been tried out. To evaluate each method, the sensory analysis technique has been applied. Three candidate pretreatments chosen were (1) soaking in boiling water, (2) steaming, and (3) frying. The panel composed of 11 female students removed the pellicle of pretreated chestnuts, and graded the easiness. In addition, the time needed has been measured to remove the shell and peel off the pellicle of each pretreated chestnut and untreated one. The frying method was found to be the best. It reduced the time needed by 60% compared to that for untreated samples. The steaming method was also significantly effective. Soaking in boiling water makes no effect for this purpose.
