Abstract
This paper explores the claims that lemon helps lose weight by facilitating digestion.The effect of varying volumes of lemon juice on the rate of digestion was investigated through series of controlled experiments as “How does the increasing amount of freshly squeezed citrus limon juice affect the rate of digestion of proteins in stomach, when digestion is monitored using a pH meter?” is the topic of investigation concerning this essay.The digestion of proteins in the stomach is characterized by the decrease in pH as aciditiy increases with the hydrolysis of proteins.To be able to evaluate the rate of digestion, the change in pH of the stomach was observed on a model resembling the digestive qualities of the stomach, such that the width of the gap between the initial and final pH is directly proportional with the rate of digestion. Identical solutions of gastric juices composed of pepsin and HCl, were added differing volumes of lemon juice to monitor the digestion of chewed lamb meat. While the beakers were kept in a water bath set to stabilize the temperature at 36.5◦C, the homeostatic temperature of a healthy human body. Experiments revealed that solutions containing higher volumes of lemon juice tend to show a greater change in pH. Although the mean change in pH was observed to be constant for sets containing 2 and 3 ml of lemon juice, Anova single factor test revealed that the overall variations between sets were significant. White residue was observed on digestive solutions containing more than 3 ml of lemon juice. Although the results of the experiment are not enough to evaluate the effect of lemon juice on weight loss, the awareness that lemon juice increases the rate of digestion can pave the way for other investigations as the topic concerns a wide spectrum of biological phenomena.
