Antioxidant and Sensorial Properties: Meat Analogues versus Conventional Meat Products

Meat-product alternatives have become more popular among consumers, mainly due to concern for animal welfare and demand for more eco-friendly production. This study focused on the comparison between the antioxidant capacities of selected types of meat products and those of their plant-based alternatives. The analogues of the following products were analyzed: minced meat, burger, steak, Hungarian sausages, Frankfurter sausages and salami. Total polyphenol contents and antioxidant capacities and sensory profiles of the products were determined. The highest polyphenol content (1.85 mg Gallic acid/g) and antioxidant capacity values (DPPH: 41.80% inhibition, CUPRAC: 9.21 Trolox mmol/kg, FRAP: 7.51 mmol/g, ABTS: 7.45% inhibition) were observed in the analogue samples of Hungarian sausages due to the oat flour presence in these products. The results indicated that antioxidant properties of meat analogue products (plant sources) were superior compared to conventional meat products (produced from animal sources). The sensorial attributes indicated no significant (p > 0.05) differences in taste (except the Frankfurter sausages). The novelty of the study can be seen in the fact that it confirmed that the sensory properties of meat analogue products can be close to those of traditional meat products.

Automated summary

This study compares the antioxidant capacities of meat products and their plant-based alternatives and finds that the plant-based alternatives have higher polyphenol content and antioxidant capacity compared to traditional meat products. In terms of sensory attributes, there are no significant differences between the two except for Frankfurter sausages.
