Abstract:
Taking lolus sprout as materials,the effect of four kinds of color fixative，i.e，Vitamin C，phytic acid，sodium bisulfite and sodium sulfite on quality and color protection were studied，and three methods，i.e，blanching enzyme inactivation，soaking and vacuum infiltration process on color protection of lotus sprout coating with chitosan were researched.The proper color fixative and the process were obtained.The results showed that the best composition of preservation solution contain 0.2% VC，0.6% phytic acid，0.2% citric acid and 1% calcium chloride.The best process of color protection was vacuum infiltration.According to the proper technology above adding with the best preservation solution，Lotus sprout could maintain good color，which was one of the best methods.
