  • Figure 1. Comparative chromatogram of standard and sorghum tannin. (A) Epigallocatechin; (B) Catechin; (C) Epicatechin; (D) Epicatechin gallate; (b) Catechin in the sample; (c) Epicatechin in the sample; (d) Epicatechin gallate in the sample. Red, mixed standard; Blue, sorghum tannin extract. The sorghum seed pictures in the figure are Is-2803 (Is28, brown), GanzaoShua (Gzs, white), Dahong Pao (Dhp, red), Niangao Liang (Ngl, cherry red), Heigao Liang (Hgl, black) and Tx430 (yellow) from left to right. The inserted table shows the tannin content of the six sorghum varieties

  • Figure 4. Comparison of antioxidant capacities of tannin extract, BHT and TP on pork during storage at 4°C. (A) TVB-N; (B) TBA. A, B Means with different superscripts are significantly different within days of preservation at 4 degree (P<0.05). a, b, c Means with different superscripts are significantly different within tannin extract level (P<0.01)
