摘要:

对黄海胆棘壳色素理化性质及稳定性进行研究。结果表明:黄海胆棘壳色素在水、甲醇等极性溶剂中溶解性较好,在石油醚、正己烷等非极性溶剂中溶解性较差;在酸性环境中显橘黄色,在碱性环境中显土黄色;耐热性较好,但耐光性较差;Na2SO3和山梨酸钾既可引起色素颜色改变,又可降低色素稳定性;H2O2和NaCl不改变色素颜色,但可降低色素稳定性;高质量浓度蔗糖可增强色素稳定性;VC对色素起到护色增色作用。

Abstract:

The present study aimed to characterize physicochemical properties and stability of pigments extracted from the spine and shell of sea urchin (Glyptocidaris crenularis). Our results showed that the pigments had relatively high solubility in polar solvents such as water and methanol but had relatively low solubility in non-polar solvents such as light petroleum and hexane. The pigments showed orange color in acidic conditions but yellowish brown color in basic conditions. The pigments were relatively stable to heat but unstable to light. Na2SO3 and potassium sorbate could not only cause changes in the color but also decrease the stability of the pigments. H2O2 and NaCl could not cause any changes in the color but decrease the stability of the pigments. High concentrations of cane sugar could enhance the stability of the pigments. Vitamin C could protect and enhance the color of the pigments.

Key words: Glyptocidaris crenularis, pigment, physico-chemical properties, stability
