The content of organic acid in mango and its effect on the digestive function of mice and rats.

To study the changes of organic acid content in mangoes of different maturity and their effects on the digestive function of mice and rats. The acid-base titration method was used to determine the organic acid content in the fruit, and the effects of mango fruits of different maturity or compatibility on the digestive function of animals were evaluated through the mouse small intestine exercise experiment, the rat feeding experiment and the determination of digestive enzymes. The results showed that the organic acid content (calculated as citric acid) in raw fruit, green ripe fruit and ripe fruit were 1.02%, 1.63% and 0.12%, respectively. Ripe fruit has no effect on the digestive function of experimental animals. Both raw fruit and green ripe fruit can promote the digestive function of experimental animals, and green ripe fruit is the best. The addition of gardenia and mango leaf powder to the green ripe fruit can not only significantly improve the gastrointestinal motility, gastric juice volume, pepsin activity and excretion of experimental animals, but also significantly increase its total weight gain and food utilization rate.
