摘要
通过正交实验,以黑玉米吸光度及净重为指标,优选出黑玉米色素提取工艺最佳条件是:pH值为9的蒸馏水、料液比1:15、40℃恒温水浴提取2次,每次1h。对黑玉米色素的稳定性研究结果表明:色素最大吸收波长为210nm;该色素具有较强的耐酸性、耐还原性、耐盐性,其在酸性条件下耐光性极佳。
Throunh orthogonality experiment, it is index to survey dark corn absorbance and net weight, good choose dark corn black draw technology best clndition is: pH is the distilled water of 9, material liquid than 1:15 and 40℃ the water bath of constant temperature draw two tinies, every time 2h. For dark corn, the stability research result of pigment shows: Pigment biggest absorption wavelength is 210nm; This pigment has more strong acid-resistingness, endure reproducibility, endure salt.
