A new application of hydrocolloids from Echinops setifer (Shekartighal): Mayonnaise-type sauces

Due to the importance of the production of functional and nutraceutical foods with high added value, Shekartighal was used to develop ready-made functional mayonnaise-type sauces and evaluate their physicochemical, sensory, and antioxidant properties over 60 days of storage. Shekartighal had, on average, 76.85% carbohydrate, 9.24% protein, 4.91% fat, 1.74% ash, 7.26% moisture, 20.38 mgGAE/g total phenol content, 14.31 μM ferrous sulphate/g, and 145.12 μg/mL antioxidant activity. The results indicated that Shekartighal had high water absorption capacity (408.01%) and emulsion stability (91.83%). Following the textural and sensorial study, the product that stood out as the best performer was the sauce containing 3% Shekartighal. Consequently, this product was selected for further evaluation, where its physicochemical and antioxidant properties were assessed for a 60-day duration under refrigerated storage (4°C). The formulation with 3% Shekartighal presented significantly more phenolic content and antioxidant properties than the control. During the 60-day refrigerated storage (4°C) period, the physicochemical and antioxidant parameters of the enriched sauce remained stable. The addition of Shekartighal to the sauce significantly improved its nutritional quality, and the sauce enriched with 3% Shekartighal demonstrated the most favorable characteristics among the different concentrations tested. Overall, these findings suggest that Shekartighal could be utilized as a natural ingredient to create a functional sauce with notable antioxidant and nutritional properties.
