Characterization of Goat Milk Fermented With Streptococcus thermophilus, Limosilactobacillus mucosae CNPC007 and Inulin With Addition of Cereus jamacaru

open access: yesApplied Research, Volume 5, Issue 3, June 2026.
Limosilactobacillus mucosae maintained viability above 7 log CFU/g during storage of the fermented goat milk with inulin and Cereus jamacaru jam and survived over 4 log CFU/g during the in vitro gastrointestinal simulation. This jam enriched the total phenolic content of the fermented milk that achieved overall acceptability scores close to or above 7.
