AI Technical Summary

Technical Problem

Existing methods cannot fully reflect the digestion process and nutrient absorption of wheat oligopeptide-rich compressed dry food in the human gastrointestinal tract, and there are problems with noisy data and data inconsistency in data processing, resulting in inaccurate evaluation results.

Method used

The digestive process was simulated using an in vitro dynamic human gastrointestinal digestive system. Combined with data cleaning, classification and value consistency processing, cross-correlation calculation, singular value decomposition and autoregressive-moving average modeling were used to conduct multi-dimensional evaluation. The digestive performance was quantified by a discriminant model.

Benefits of technology

This enables a comprehensive and accurate assessment of the digestibility of compressed dry grains rich in wheat oligopeptides, providing a scientific basis to support product development and quality improvement.
