The Claim

The food matrix structure (e.g., gel versus liquid form) significantly affects the digestibility of sulphur-containing amino acids in minipigs when the protein source is held constant.

Source: True ileal amino acid digestibility and digestible indispensable amino acid scores (DIAASs) of plant-based protein foods.

How it works
1 study reviewed
In plain English

When sulphur-containing amino acids are delivered in a gel form like tofu versus a liquid form like soya milk, their digestion in minipigs is different, even when the same protein is used in both forms.

See the scientific wording

The food matrix—such as whether a protein is in a gel (tofu) or liquid (soya milk)—significantly affects the digestibility of sulphur-containing amino acids in minipigs, even when the protein source is identical.

Why this might work

When soy protein is turned into a solid gel like tofu, the protein folds into tight clumps that hide sulphur-containing amino acids inside. Digestive enzymes cannot reach these hidden amino acids well, so they are not broken down properly. The gut responds by releasing more of its own proteins and mucus to deal with the undigested material, which carries away the unused amino acids before they can be absorbed. This makes fewer sulphur-containing amino acids available for the body to use.

    Even though tofu and soya milk come from the same soybeans, your body absorbs the important amino acids better from the liquid version than the solid gel, because the way the food is structured changes how easily your body can use those nutrients.
