Enhancing Nutrient Profile and Reducing Acrylamide in California-Style Table Olives with Cassia grandis Fortification.

In this study, Californian-style black table olives were enriched with fresh and lyophilized "Carao" (Cassia grandis L.) to enhance their mineral composition, antioxidant activity, phenolic compound content, and to evaluate their potential for reducing acrylamide levels. Mineral concentrations were quantified using inductively coupled plasma optical emission spectrometry (ICP-OES). The addition of both fresh and lyophilized "Carao" significantly increased the iron concentration in the olives. Additionally, levels of calcium, magnesium, and potassium were elevated in both "Carao" treatments. Among the treatments, the addition of fresh "Carao" resulted in the highest increase in antioxidant activity, followed by the lyophilized "Carao", with increases of 62.3% and 68.3%, respectively. The effect of fresh and lyophilized "Carao" on acrylamide reduction in oxidized olives is also discussed.
