The biological efficacy of different concentrations (2%, 4%, and 6%) of destoned olive cake (DOC) as improvers of
the quality, storability, and safety of beef pattieswas investigated. Increasing the percentage of DOC in the patties
improved (P ≤ 0.05) the protein and fat contents, cooking yield, moisture and fat retention, total phenolic, and
DPPH radical scavenging activity, while the dimensional shrinkage and TBARS showed a progressive reduction.
The pH of the patties decreased gradually with the storage time. DOC-incorporated patties showed significantly
(P ≤ 0.05) lower total plate count than untreated. Surface color values of raw beef patties were decreased gradually
with the storage time. Throughout the storage period, all the sensory traits of non-formulated patties
were significantly (P ≤ 0.05) reduced, whereas the formulated patties revealed considerable stability of all characters.
Overall, this study identified antioxidant and antimicrobial potentiality of DOC, which could pave the way
for its use as an extender of the shelf life of the patties.
