Abstract: | [ Objective ] The research aimed to get the optimalextraction condition of small highly active plant Triticale phytase. [ Method ] Taking a food and forage triticale 209 as material, the optimum extraction condition was explored. Coomassie brilliant blue method was used to measure the totaFprotein content. And according to the new standard, vanadium ammonium molybdate method was used to measure the phytase activity. [ Result ] The optimum extracting condition was as follows: pH 5.0, solid-liquid ratio 10,200 r/mim range 1 h, not adding surfactant Triton X-100. [ Conclusion] The study of wheat and barley extract phytic acid enzyme technology was suitable for practical applica- tion. |
