The Statistical Analysis About Taste Of Youth In Some Beverage
Principal Component Analysis, or PCA, is a methods of reducing the dimensionality of a data set consisting of many variables such that most of the information in the data is preserved. We measured chemically sweetness, sourness, salt and umami contained in several commercially available tomato juices and identified the principal components of a four-dimensional data set consisting of them. In result, we found that the first component of the data set has strongly positive correlation with the total estimation of sensory test by young adults around twenty years of age.
