The composition of tomato fruit. I.—The expressed sap of normal and ‘blotchy’ tomatoes

Comparison of normally ripened tomato fruit and fruit showing uneven pigmentation has revealed considerable differences in composition. Thus the normal fruit had a significantly higher content of dry matter, and higher concentrations of total solids, reducing sugars and nitrogenous compounds were found in sap expressed from normal than from blotchy fruit. Sap from normal fruit also had the higher titratable acidity and lower pH.
