The analysis and determinations had as purpose establishing the quality of fruits at four sorts of tomatoes from crops set up in the field, by seedling. Tomatoes are cultivated for their fruits that have a pleasant taste and a very high food value. Their nutritive value does not consist in relatively modest content of carbohydrates, but especially in mineral substances and vitamins. Out of the vitamins comprised by tomatoes, the most important are: A vitamin (the importance for the eye and for endocrine processes), B complex (B1, B2, B5, B6 – protectors of the nervous system, of the bones’ system, of metabolism), C vitamin (necessary to cardiovascular system, to nervous and endocrine system), E vitamin (vitamin of youth and fertility) and K vitamin (important for the synthesis of certain figurate elements of the blood). The establishing of the quality of fruits was made through determining the physical characteristics (average weight, form – expressed by the form index, specific weight), chemical composition (total dry substance, humidity, soluble dry substance, titrable acidity, ascorbic acid) and the morphological composition of the fruits (pulp, membrane, seeds).
