摘要
比较了黑莓品种Boysen、Kiowa和高粱泡(Rubus lambertianus Ser.)果实色素的光谱特性和理化性质,主要包括光照、温度、pH、氧化剂和还原剂5个因素对三种色素水溶液稳定性的影响。结果表明,黑莓Boysen、Kiowa和高粱泡果实色素对光、热有较好的耐受性,对pH、氧化剂和还原剂较为敏感,其中Boysen色素的光稳定性较强;高粱泡色素的热稳定性较强;Kiowa的光和热稳定性均较差,耐氧化性较强。
The spectral and physicochemical properties of pigment extracted from fruit of blackberry cultivar Boysen, Kiowa and Rubus lambertianus Ser.were investigated, including the effects of light,temperature, pH value, oxide-reducing medium on stability.The result showed that the three pigments had higher stability to light and heat,and poor stability to pH value,oxidant and reducer.Pigment of Boysen had the better light stability.Pigment of Rubus lambertianus Set.had better heating and pH stability.Pigment of Kiowa had lower light and heating stabilities and better anti-oxidation.
