The protein extracted from the tea-leaf was obtained by alkaline extraction and acid precipitation, which optimized the extraction process, and the protein from the tea-leaf after zymohydrolysis was added to pig’s basal diet as feed additive. The results showed that the best process of the protein extraction from tea-leaf was with 0.12mol/L NaOH concentration, 90 ℃ extraction temperature, 1.5h extraction time, 30:1 (w / v) liquid feed ratio, and the optimum precipitation was pH 3.5, and the extraction of tea-leaf protein was 75.47% under these conditions. The flavor protease enzyme was used to zymohydrolyze the tea-leaf protein, the hydrolysate of which could highly increase the pig’s productivity, improve its immune capacity and raise the activity of digestive enzymes.in pancreas and duodenum. |
