titled"Effects of high hydrostatic pressure treatment on bacterial composition in donkey milk studied by high throughput sequencing" on 17 April 2023.
This study explored the microbial landscape of donkey milk, researchers employed culture-dependent methods to examine the growth of microbial populations. Initial observations showed that the total bacterial count increased to 5.71 log cfu/mL , 6.87 log cfu/mL and 8.21 log cfu/mL after 5, eight and 12 hours of incubation, respectively.
HHP application on these samples revealed a remarkable bacterial reduction, demonstrating a decrease of approximately 3–4 log cfu/mL . This analysis illuminated distinct microbial shifts: both untreated and HHP treated samples predominantly harbored Proteobacteria. However, HHP decreased the abundance of Pseudomonadaceae and Moraxellaceae by 4.92% and 4.46%, respectively, whereas Enterobacteriaceae and Erwiniaceae increased their proportions at the family level by 6.77% and 0.83%, respectively. The effect of HHP treatment on microbial composition and its inactivation of pathogens was revealed through a combination of culture-dependent and HTS methods, making it a promising tool for microbial management of donkey milk.
In conclusion, this study emphasizes the efficacy of high hydrostatic pressure treatment in enhancing the safety of donkey milk without compromising its nutritive elements. These findings reveal innovative approaches to donkey milk processing, paving the way for safer consumption and potentially broadening the market appeal of
