中文摘要: |
水蜡树果实的天然花青素含量丰富,为了更好地利用这一资源,文章研究了pH、光、温
度、金属离子、氧化剂、还原剂和食品添加剂对天然花青素稳定性的影响. 试验发现,水蜡树果实花
青素在pH = 3~8 下稳定性较好;自然光、较高温度、高浓度Na2SO3、H2O2和Cu2+可破坏花青素;K+、
Na+、Fe3+、较低浓度(10 mg/L 和25 mg/L)Na2SO3、蔗糖、葡萄糖和麦芽糖对花青素稳定性影响较小;可
溶性淀粉可减弱色度,Zn2+、Al3+、Mg2+和柠檬酸可起到增色作用. 为了保证水蜡树果实花青素的稳定
性,应避光保存,避免温度超过50 ℃. |
英文摘要: |
The effect of pH, light, temperature, metal ions, H2O22, Na2SO3, and food additives on the stability of anthocyanin
from fruit of Ligustrum obtusifolium is studied for the rich resources of privet(Ligustrum obtusifolium)fruit and high contents of anthocyanin on the fruit. The results show that the anthocyanin from fruit of Ligustrum obtusifolium can be used in
pH = 3~8, and it can be destroyed by light, H2O2, higher temperature, high Na2SO3 concentration. Cu2+. TK+, Na+, Fe3+, 10
mg/L Na2SO3, 25 mg/L Na2SO3, sucrose, glucose, and maltose have less effects to the stability of anthocyanin., tarch weaks its
color, and Zn2+, Al3+, Mg2+, and citric acid enhance its color. Thus it should be kept in dark place, and avoid to be heated
above 50 ℃ for stability. |
