Pineapple

PINEAPPLE

 

     Pineapple fruits (Ananas comosus) do not exhibit a particularly high vitamin concentration, with the notable exception of ascorbic acid (49.0% of the Daily Value [DV] per 100 g). However, the fruits possess a significant mineral profile: silicon (310.0% DV per 100 g), manganese (70.0%), rubidium (63.0%), nickel (33.0%), cobalt (25.0%), chromium (22.0%), molybdenum (14.0%), potassium (13.0%), strontium (11.3%), and vanadium (10.3%).

 

     The nutritional matrix is characterized by a substantial mono- and disaccharide fraction (20.6% DV), within which glucose (17.5% DV) is the predominant sugar. Pineapple fruits are further distinguished by their total phytosterol content (10.9% DV). Starch is absent from the composition, while sucrose is present in significant quantities (4.59 g per 100 g).

 

     The total purine base content per 100 g constitutes 6.7% of the daily allowance.

 

     The concentration of oxalic acid per 100 g is minimal (1.5 mg), representing 0.4% of the maximum tolerable daily intake (for further details, see Rhubarb).

 

     Furthermore, it is established that pineapple fruit contains the proteolytic enzyme bromelain (a protease), which catalyzes the hydrolysis of proteins. Bromelain is frequently misidentified as a lipolytic enzyme (lipase). This protease is primarily concentrated in the fibrous central axis of the fruit (the “core”) and facilitates the digestion of dietary proteins.

 

     The diuretic effect of pineapple fruit is attributed to its relatively high potassium concentration.

 

     It should be noted that pineapple fruit exhibits a capacity to concentrate the toxic trace element strontium, containing 11.3% of the maximum daily allowance per 100 g.
