The objective of this study was the incorporation of a water–oil (W/O) nanoemulsion for the partial substitution of pig fats and the addition of antioxidant compounds in an emulsified meat system (EMS). The nanoemulsion was formulated with orange essential oil and cactus acid fruit (xoconostle). The treatments were different percentages (0, 1, 2, 3, 4, and 5%) of the nanoemulsion for the substitution of pig fat in the EMS. The proximal analysis (moisture, protein, fat, and ash), texture profile (hardness, cohesiveness, springiness, and chewiness), phenolic compounds and antioxidant capacity 2, 2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and 2-thiobarbituric acid reactive substances (TBARS) were evaluated. All variables showed significant differences (p < 0.05). The results for protein, fat, and ash exhibited increments with the addition of the nanoemulsion, and moisture loss was reduced. The profile showed increments in hardness and chewiness. The addition of the nanoemulsion incremented the phenolic compounds and antioxidant capacity (DPPH and ABTS), decreased production of Malonaldehyde, and reduced lipid oxidation. The result of the addition of the nanoemulsion in the EMS is a product with a substantial nutritional contribution, antioxidant capacity, and excellent shelf life.
The impact of incorporating bioactive compounds of xoconostle in a double emulsion (DE) formulation in emulsified pork meat products during storage was evaluated. The DE was prepared using xoconostle extract, canola oil, and whey protein. Meat products containing different percentages of DE (MPDE) were formulated: 0% (control), 5%, 10%, 20%, and 30%. Evaluation of physicochemical parameters, texture profile, total phenols, antioxidant capacity, and oxidative stability was performed within 35 days. Differences were observed in the physicochemical parameters of meat products, with increased moisture and protein content compared with the control. Regarding texture, hardness and chewiness were directly proportional to the quantity of added DE. MPDE 30% maintained a high concentration of phenolic compounds. Furthermore, with the addition of DE, it was possible to maintain a good oxidative stability. Our findings show that the incorporation of xoconostle in DEs can significantly improve the physicochemical properties, texture, and antioxidant activity of emulsified meat products.
