Abstract: :The effects of different indoor starvation and purification times (0, 1, 2, 3, 4, 5 d) on the quality parameters such as basic nutritional composition, water holding capacity, texture, and histological characteristics of Siniperca chuatsi were studied. The results showed that with the increase of starvation time, the fat content began to decrease significantly from the second day, significantly lower than the control group before starvation. The protein content of the muscles of Siniperca chuatsi on the second day of starvation was significantly higher than that before starvation. The muscle pH of Siniperca chuatsi first significantly increased and then began to decrease, reaching its highest value on the second day of temporary starvation. Short-term temporary starvation had an impact on the water holding capacity of fish meat, the storage loss rate was the lowest on the second day of temporary starvation, and it started to recover from the third day. The storage loss rate of Siniperca chuatsi meat in 24 h and 72 h on the fourth and fifth days was higher than that before starvation. After temporary starvation, the muscle hardness and chewiness of Siniperca chuatsi first increased, and decreased significantly on the fourth and fifth days. The recovery of Siniperca chuatsi muscle showed little variation in the first three days, and the recovery of fish meat increased on the fourth and fifth days. Compared with before temporary starvation, the muscle fiber diameter of Siniperca chuatsi decreased first and then increased after temporary starvation. On the second day of temporary starvation, the muscle fiber diameter was the smallest and the muscle fiber density was the highest, significantly higher than that before temporary starvation. Temporary starvation could improve the microstructure, meat quality, and the body color of Siniperca chuatsi, and increase its brightness and whiteness. The experimental results indicated that short-term temporary starvation could improve the muscle quality of Siniperca chuatsi to a certain extent. Considering the comprehensive quality effect and production economic benefits, the suitable indoor temporary starvation purification treatment time for Siniperca chuatsi under the experimental conditions was 2 days.
