Improvement in texture and flavor of prepared meat patties with natural marination ingredients

This study investigated the effects of four natural ingredients including Lentinula edodes (L. edodes) powder, yeast extract, germinated brown rice (GBR) powder, and chicken soup on the texture and flavor of prepared meat patties. Samples were subjected to five marinating treatments (Con group: basic formulation; non-LE group: formulation without L. edodes powder; non-CS group: formulation without chicken soup; non-YE group: formulation without yeast extracts; AI group: all ingredients included). The results showed that the four treatments, using different ingredients, significantly reduced reheating loss. Compared to the other groups, the AI group exhibited the highest percentage of P₂₁ (the proportion of immobilized water in the total water content). The texture of the four treatment groups were improved to the same extent. Non-LE, non-CS, and non-YE groups showed a significant increase in umami and sweet taste amino acid contents. Meanwhile, high levels of flavor nucleotides, aldehydes, and esters were observed in the non-CS and AI groups., with the non-CS group receiving the highest sensory score. These findings suggest that the non-CS group offers a better combination of natural ingredients, indicating its potential for developing premium, flavorful meat patties.
