【摘要】 对黑甜玉米色素的提取试验结果表明,该色素提取的较优条件为:浸提剂为0.1mol/LHCl溶液,配料比为1:10,提取温度为70℃,提取时间为12h。水溶性色素,在酸性条件下稳定,最大吸收波长为445nm。该色素pH<5时,热稳定、光稳定性较好。蔗糖、葡萄糖、抗坏血酸等对色素没有影响。除了Fe3+,其他金属离子对色素无影响。更多还原

【Abstract】 In this paper,the pigment extraction and stability of black sweet corn have been studied.The optimums extraction are that solvent is 0.1 mol/L HCl,solvent volume to sample weight ratio is 1:10,extraction temperature is 70℃,and extraction time is 12h.The pigment is water-solubility with high stabilization under acor condition and wavelength of maximum absorption is 445nm.The thermo stabilization and light stability of this pigment is better for pH<5.Sucrose,glucose,and Vitamin C etc.have no effect on the pigment,so do the metal ions except Fe3+.更多还原
