Stingless bees (Hymenoptera; Apidae; Meliponini), with a biodiversity of 605 species, harvest and transport corbicula pollen to the nest, like , but process and store the pollen in cerumen pots instead of beeswax combs. Therefore, the meliponine pollen processed in the nest was named pot-pollen instead of bee bread. Pot-pollen has nutraceutical properties for bees and humans; it is a natural medicinal food supplement with applications in health, food science, and technology, and pharmaceutical developments are promising.

Helicobacter pylori (HP) is a causative agent in gastric cancer (GC). In the United States, HP is more prevalent in racial and ethnic minorities, including African Americans, Asian Americans, Latinos, and immigrants, the same groups that are more likely to develop and die from GC. Although screening for HP is not presently performed in the United States, there are plausible benefits to doing so, because HP is considered a group 1 carcinogen by the World Health Organization, and its link to GC parallels that of human papilloma virus and cervical cancer.

However, carboxylic acids are produced in highly diluted mixtures, challenging the recovery and purification, and resulting in high production costs, polymerization, and thermal degradation of some of the products. The protection of the acid function by esterification reaction is one of the most promising alternatives through reactive distillation (RD); this technique allows simultaneously the recovery of carboxylic acids and the elimination of most part of the water.
