The antihyperglycemic effect is associated with the pre-hispanic fruit xoconostle or tunillo (Stenocereus stellatus, Pfeiffer and Riccobono). This fruit includes in various varieties, distinguished by color. Xoconostle fruits are highly perishable. Therefore, the aim of this study was to assess antihyperglycemic effects of xoconostle juice before (fresh) and after pasteurization. The study focused on the white and red varieties of xoconostle.

In this study, the method involved collecting juice from xoconostle fruits, followed by pasteurization. Chemical, physical and microbial parameters were assessed for the juice and the ability to decrease capillary glucose levels (antihyperglycemic effect) was assessed in male Wistar rats.

Pasteurization process led to decreases in total phenolic content of the red variety of xoconostle fruit, while the white variety showed increases in malic acid content. Despite these changes, fresh and pasteurized juices of the two varieties showed lower blood glucose levels, compared to the control group. Red variety demonstrated a stronger antihyperglycemic effect. In conclusion, pasteurization did not affect pharmacological effects of xoconostle juice, making it a viable preservation method without compromising the antihyperglycemic characteristics. Results of this research suggest aconservation method which preserve the antihyperglycemic effects while extending its shelf life.
