Chickpea cell digestion studied in lab tests

What it found

In lab tests, changing the stomach acid conditions during digestion changed how fast and how much starch broke down from inside chickpea cells, by up to 25%.

Protein breakdown in the small intestine was little affected.

What they found

Animal and lab studies

Starch digestion changed

A gradual stomach pH change, with or without salivary amylase, altered the rates and extents of starch digestion by 25% in lab tests.

Protein breakdown little affected

Little effect on small intestinal protein breakdown was seen when comparing the different digestion conditions in lab tests.

Starch and protein linked

Starch and protein are co-embedded in the chickpea cells, and their digestion was found to be interdependent in lab tests.

What the authors conclude

“The insights generated in this study demonstrate the possibility of using a hypothesis-based approach to introduce dynamic factors to in vitro models while sticking to simple and cost-efficient set-ups.”

Also in their conclusions

  • They say the insights show it is possible to use a hypothesis-based approach to add dynamic factors to lab models while keeping set-ups simple and cost-efficient.

How it was done

The authors wanted to see whether adding dynamic factors to simple lab digestion models changes the results, since more complex models are costly and time-consuming.

They used individual cotyledon cells from chickpeas and compared a static stomach pH with a gradual pH change from 6.3 to 2.5 over 2 hours, with and without added salivary amylase, starting from the INFOGEST static protocol.

What it can’t tell you

  • We summarised it from the abstract only.
  • These are lab tests on chickpea cells, not studies in people. They cannot show what happens when someone eats chickpeas.
