The integration of aqueous clove extract (ACE) and spray-dried probiotics into an
edible film presents numerous health advantages, such as enhanced probiotic stability
and antibacterial efficacy against harmful bacteria like Klebsiella pneumoniae and
Pseudomonas aeruginosa. This study aimed to formulate a probiotic edible film with
antibacterial properties by incorporating milk powder containing ACE and probiotic
strains, namely Streptococcus thermophilus ATCC 19258, Lactobacillus bulgaricus ATCC
11842, and Lactococcus lactis MG1363. The milk powders, containing 7.5% (w/v) ACE
with various probiotic strains, were combined with 2% (w/v) pectin biopolymer and 60%
(w/w) glycerol plasticizer to produce the probiotic edible film with ACE. Antibacterial
effects were investigated using disc diffusion, while probiotic film viability was assessed
through the pour plate method. The study revealed higher viability in the probiotic
strains L. lactis and S. thermophilus within the edible film, compared to L. bulgaricus.
The specific strains exhibited increased antibacterial activity against K. pneumoniae and
P. aeruginosa, underscoring the critical role of probiotic strain selection in determining
functional properties. Notably, the edible film containing L. lactis and S. thermophilus
demonstrated substantial antibacterial activity against both pathogens. However, further
research is imperative to optimize industrial-scale production methods, assess efficacy in
diverse food items, evaluate sensory properties, gauge barrier attributes, and investigate
the impact of storage conditions on stability and performance.
