the hydrochloric acid is likely to prevent the digestion of starch by carbohydrase enzymes in the stomache because the carbohydrase enzymes optimum PH is PH7. The Hydrochloric acid in the stomache makes the PH in the stomache PH3 therefore the stomache has too weak a PH for the enzymes to be able to work.
