| Research Abstract |
It has been difficult from the results of previous studies to identify any mutual relationship among starch samples from different origins. The present study, however, of measurements taken from starch samples from ten different origins, and using data from past studies on identical samples enabled a principal component analysis to be carried out. The results show an identifiable relationship among the starch samples.
We collected words of evaluation for preference during the whole process of eating. In this study, we used tomato as a sample for collecting expression words during whole eating process. Words expression the features were collected and 91 pairs of words were selected to formulate the evaluation sheet for sensory evaluation. Principal component analysis was applied both for mean average scores of 15 samples and individual scores of total 307 samples. Results in both cases showed that the total variance was mainly explained by two components.
