Bioavailability of Essential Minerals from Staples Commonly Consumed in the Tropics
Bibliographic record
Abstract
<p>This study assessed essential minerals in sweet cassava (<em>Manihot esculenta</em>), Lucea yam (<em>Dioscorea rotundata</em>), plantain (<em>Musa sp</em>.) and pumpkin (<em>Cucurbita pepo</em>) by atomic absorption spectrophotometry while mineral bioavailabilities were assessed by <em>in vitro</em> enzymatic digestion.</p> <p>Undigested cassava samples displayed highest calcium concentrations (3150 ± 320 mg/Kg) while the highest iron concentrations were recorded in pumpkin samples (81.5 ± 4.7 mg/Kg). Magnesium concentrations were highest in ripe plantain samples (963 ± 15.18 mg/Kg) while the highest zinc concentrations were recorded in cassava (15.23 ± 4.07<sup> </sup>mg/Kg). Cooked samples displayed higher percentages of available minerals than uncooked ones with unripe plantain displaying highest percentage soluble calcium (12.945), iron (37.19%) and magnesium (23.37%) while the highest percentage soluble zinc was observed in sweet cassava (9.87%).</p> The samples assessed are important contributors of essential dietary minerals especially in the cooked states. These staples have untapped potential for increased economic relevance especially with increasing costs of food production. Studies aimed at increasing mineral bioavailability in some samples are needed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
