To reduce salt content and enhance calcium in chicken patty, shell calcium powder (SCP) was added, and transglutaminase (TG) was included to improve its properties. Five different treatments were prepared to assess the effects: CON (2% salt), T1 (0.75% salt + 0.2% SCP), T2 (0.75% salt + 0.2% SCP + 0.2% TG), T3 (0.5% salt + 0.4% SCP), and T4 (0.5% salt + 0.4% SCP + 0.2% TG). Reducing salt led to decreased ash content and increased cooking loss. The addition of SCP and TG raised pH levels. Meat color remained consistent with different salt, SCP, and TG levels. However, when salt was reduced to 0.5% and SCP was added at 0.4% without TG, the patty's hardness and chewiness decreased. Sensory evaluations showed reduced juiciness when salt was reduced to 0.5% and SCP was added at 0.4%, but no significant differences were observed in overall acceptability. Salt had no impact on TBARS results, but salt reduction to below 0.5% increased susceptibility to microbial contamination. In summary, reducing salt and adding SCP had minimal sensory impact, but when salt is reduced to 0.5% or lower, consider adding TG. Also, when decreasing salt, additional preservatives should be considered to address potential microbial contamination during manufacturing.
