What property of purple potato starch resists digestion in the small intestine?
Answer
Resistant starch
A portion of the carbohydrate structure within the purple potato can manifest as resistant starch. This type of starch is characterized by its inability to be fully digested or absorbed in the small intestine, which is why it is aptly named. Upon reaching the large intestine, the resistant starch undergoes fermentation. This fermentation process is highly beneficial as it serves a prebiotic function, meaning it feeds and nurtures the population of beneficial bacteria residing in the gut microbiome, thus contributing to overall digestive health.
