Potential of date palm spikelet extract as an anti-oxidative agent in set-type yogurt during cold storage

The study aimed to evaluate the effects of date palm spikelet extract (DPSE) from two cultivars on chemical, antioxidants, and sensory properties yogurt. DPSE Rziz (Rz) Khalas (Kl) contains high levels total phenolics flavonoids as well phenolic compounds with an antioxidant activity exceeded 90%. Increasing concentration in yogurt improved solids, protein, ash, compounds, flavonoids, even during prolonged storage periods. thiobarbituric acid reactive substances (TBARS) was decreased by adding but increased time. Throughout period, DPSE-formulated revealed better stability terms its physicochemical, antioxidative, characteristics compared non-formulated findings this proved potential 0.5–1% for both cultivars, superiority Rz a functional additive preserve
