    摘要:

    用冷冻干燥法制备黑米麸皮花青素脂质体前体——花青素脂质体冻干粉。以脂质体冻干粉复水后的渗漏率、粒径、Zeta电位等为考察指标,研究预冷冻温度、添加冻干保护剂海藻糖、蔗糖及其分别与甘露醇复配后对黑米麸皮花青素脂质体冻干粉质量的影响。结果表明:预冷冻温度对花青素脂质体冻干粉的质量无显著影响。单独使用海藻糖或蔗糖做保护剂时,当大豆卵磷脂与保护剂质量比为13,制备得到的花青素脂质体冻干粉复水后的渗漏率最低,分别为16.64%和12.50%;海藻糖或蔗糖分别与甘露醇复配均能对花青素脂质体起到协同保护作用,当大豆卵磷脂蔗糖甘露醇质量比为132时,所得脂质体冻干粉复水后渗漏率最低,为7.45%,平均粒径为346.1 nm;而当大豆卵磷脂海藻糖甘露醇为132时,所得脂质体冻干粉复水后的渗漏率为9.65%,平均粒径为364.6 nm;脂质体冻干粉复水后Zeta电位变得更负,脂质体稳定性有所提高。用蔗糖和甘露醇复配做保护剂制备得到的花青素脂质体冻干粉的质量最佳。

    Abstract:

    The powder of black rice bran anthocyanins liposome (proliposome) was prepared by lyophilized methods. The effects of pre-frozen temperature and different protectants of mycose, sucrose, mannitol on the qualities of lyophilized anthocyanin liposome were investigated by inspecting the leakage rate, particle size and Zeta potential of reconstituted liposome. The results showed that the pre-frozen temperature had no significant effect on the qualities of lyophilized liposome. The leakage of reconstituted liposome were decreased by using protectant mycose or sucrose alone, and reached lowest value of 16.64% and 12.50% respectively by control the mass ratio between soybean lecithin and protectant at 31. Combination using of mannitol with mycose or sucrose showed a synergistic protective effect. When WSoybean lecithinWsucroseWmannitol=132, the reconstituted anthocyanin liposome had the lowest leakage rate of 7.45% and the average particle size of 346.1 nm. While, when WSoybean lecithinWmycroseWmannitol=132, the leakage of reconstituted liposome was 9.65% with the average particle size of 364.6nm. The Zeta potential became more negative after reconstituted the lypholized liposome, which suggested that the stability was increased. The results indicated that the lyophilized anthocyanin had best quality when the mixture of sucrose and mannitol was used as protectant.
