Structure of starch hydrolysates following in vitro oral digestion: Effect of botanical source of starch and hydrothermal treatments
Bibliographic record
Abstract
Abstract Digestion of starch in humans occurs progressively in the gut. However, the literature is scant on the structures of the starch digestion products along the gut from the mouth to the small intestines – products that impact glucose homeostasis. This submission focuses on the first step of starch digestion, i.e., impact of human salivary amylase on the structure of hydrolysis products obtained from cooked starches from different botanical sources. Normal corn (NCS), normal wheat (NWS), and normal potato (NPS) starches were cooked at 1:0.7 (T0.7) or 1:2 (T2) starch:water ratios. Cooked starches were subjected to salivary amylase at conditions mimicking oral digestion. Extent of hydrolysis was lower at T0.7 compared to T2, but the amount of carbohydrates in different fractions and the MW profiles within each treatment showed no apparent differences between starches from different botanical sources. However, debranching of the hydrolysates revealed structural differences between the different starches with regards to extent of amylose hydrolysis and the amount and profile of lower MW fractions. Therefore, the structures of hydrolysates that are likely the substrate for subsequent hydrolysis in the gut are different based on cooking condition or botanical source of starch, with potential consequence for glucose homeostasis.

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.
