摘要: 以鹰嘴豆为原料,通过提取与活性炭-硅藻土柱层析分离纯化,制备得到低聚半乳糖含量为85%的α-低聚半乳糖样品(α-GOS),然后对其热稳定性、酸稳定性及美拉德反应特性进行研究。结果表明:鹰嘴豆α-GOS对热处理具有较好的稳定性,当加热温度为100℃时,鹰嘴豆α-GOS的残留率为94.27%,而同样条件下蔗糖的残留率就比较低。在酸处理的情况下,鹰嘴豆α-GOS的稳定性也较好,当pH值为3.0时,鹰嘴豆α-GOS的残留率为94.95%。鹰嘴豆α-GOS比葡萄糖的美拉德反应程度要差,当反应时间为3h时,相同条件下鹰嘴豆α-GOS的褐变程度相对于葡萄糖的70.65%。

Abstract: An alpha-galactooligosaccharides (α-GOS) sample with a purity of 85%, as determined by HPLC, was prepared from chickpea (Cicer arietimun L.) seeds by ethanol extraction and activated carbon-celite column chromatographic purification. Its thermal stability, acid stability and Maillard reactivity were investigated. The results showed that the sample had good stability at high temperature. After 30 min of heating at 100 ℃, the residual rate of α-GOS was 94.27%, while that of sucrose was lower. Chickpea α-GOS also showed good stability under acidic conditions. At pH 3.0, the residual rate was 94.95%. In addition, the Maillard reaction degree of chickpeaα-GOS was lower than that of glucose. Under the same conditions, the browning level of chickpeaα-GOS after 3 h of reaction was 70.65% of that of glucose.

Key words: chickpea, α-galactooligosaccharide, high performance liquid chromatography(HPLC), stability, Maillard reaction
