Experimental resultsof l-ascorbicacidcontentdistribution
in the fresh fruit are shown in Fig. 4. Tissue heterogeneity of
pineapple fruit indicates the need for caution in the determination of the initial content of vitamin C and explains the
variability of results obtained during the study. Similar situation was observed in green vegetables (
