Abstract
The aim of this research was to evaluate the effect of methanolic extracts from cladodes and cladode epidermis of Opuntia ficus-indica and Opuntia atropes on bovine raw milk microbiology. Methanolic extracts were obtained by maceration and added to bovine raw milk. Five repetitions per treatment were performed. A microbiological analysis was carried out 2 h after methanolic extracts were added. Aerobic mesophilic bacteria and total coliforms CFU mL-1 in raw milk decreased (p < 0.05) when Opuntia ficus-indica and Opuntia atropes extracts were added (≤ 3.1x105 and 1.5x106, respectively for aerobic mesophilic bacteria) and (≤ 1.9x105 and 1.2 x106, respectively for total coliforms). Adding this methanolic extracts to raw milk achieved Mexican quality standards for aerobic mesophilic bacteria; but not for total coliforms. However, both species reduced aerobic mesophilic bacteria and total coliforms CFU mL-1 counts improving microbiological quality of bovine raw milk.
Key words: quality of milk, Opuntia spp., secondary metabolites, polar extracts.
