The possibility of evaluating the quality of blueberry fruit in chemical terms rather than by color or organoleptic methods was considered.
The fruit of three varieties of commercial highbush blueberries at four stages of physiological maturity was analysed for total solids, water-insoluble solids, soluble solids, titratable acids, total acids, volatile acids, reducing sugars, total sugars and sugar-acid ratios.
Differences among varieties and stages of physiological maturity were sought by use of the above measurements supplemented by a study of the individual organic acid patterns of the fruit. Meaningful differences were evident among the four stages of physiological maturity for all measurements except volatile acids and total solids. Varietal differences were evident from measurements of the pH, soluble solids, sugar-acid ratios, and a number of the individual organic acids. / Land and Food Systems, Faculty of / Graduate
