| Abstract: | The sodium 2-keto-L-gulonate was obtained through ultrafiltration with the zymotic fluid produced by two-step fermentation method, and then vitamin C was prepared through esterification, lactonization, and acidation again. The technological process was simplified, energy was saved, cost was declined, and yield and quality of vitamine C was raised by this method. |
