    • 摘要: 利用气相色谱-质谱联用技术(GC-MS)测定了调味香辛料草豆蔻精油的化学成分,从草豆蔻精油(AKEO)中鉴定出了67种成分,主要为萜烯类和萜烯醇类化合物.研究了AKEO及其钾β-环糊精骨架材料包结物(K-β-CD-MOF-AKEO)对菜籽油抗氧化稳定性的影响.结果表明:添加AKEO及K-β-CD-MOF-AKEO后的菜籽油的过氧化值比未添加的菜籽油低64.3%和69.4%,酸价低55.3%和78.8%.说明二者能够有效地抑制菜籽油的过氧化值和酸价,可作为油脂的天然抗氧化剂.AKEO经过包结后稳定性增强,提高了精油的抗氧化时效.

    • 摘要: A novel ultraviolet absorption spectrometry method was developed for the quantitative determination of HABS by adding β-cyclodextrin with the molar ratio of 1∶1 in strong interference aqueous solution .The results indicated that the effect of several common interfering flooding agents (SAS ,OP-10 ,HPAM ) on the determination of HABS could be greatly reduced in β-cyclodextrin aqueous solution .Thus ,the determination errors of the determined HABS were less than 2.0% under strong inter-ference ,and the detection limit (S/N=3) of the method could be also as high was 8.3~9.1 × 10-4 mg · L -1 .Various charac-terization results including 1 H-NMR ,TG-DSC and FTIR showed the interaction between β-cyclodextrin and HABS .The results of 1 H-NMR analysis showed that HABS molecule could enter into the interior of the cavity of β-cyclodextrin molecule .TG-DSC analysis exhibited that the stable inclusion of β-cyclodextrin and HABS could be automatically formed .The interactions between the functional groups of β-cyclodextrin and HABS were showed by FTIR analysis ,which also exhibited that the stable inclusion could be formed by HABS entering from the narrow or the broad mouth of the β-cyclodextrin .The interference of the UV spec-trum of HABS could be reduced by β-cyclodextrin since the interaction between β-cyclodextrin due to the interaction betweenβ-cyclodextrin and HABS in the inclusion complex .%通过在重烷基苯磺酸盐类表面活性剂(HABS)的水溶液中加入摩尔比为1∶1的β-环糊精,利用的紫外吸收光谱检测存在强干扰影响时的HABS含量。结果表明,β-环糊精具有明显降低三采复配驱油剂中十六烷基磺酸钠(SAS)、烷基酚聚氧乙烯醚(OP-10)及聚丙烯酰胺(HPAM )等常用组分对 HABS定量产生的干扰影响,能显著降低 HABS的检测误差至2.0%以内,该方法的检出限(S/N=3)为8.3~9.1×10-4 mg · L -1。通过1 H-NMR ,TG-DSC及FT-IR表征研究了 HABS分子与β-环糊精分子之间的相互作用。1 H-NMR结果表明了HABS分子已进入了β-环糊精分子的内部空腔;TG-DSC结果表明没有自由态的 HABS存在,HABS分子与β-环糊精分子已形成了包结物;FT-IR的表征结果显示了 HABS分子与β-环糊精分子之间的官能团作用。结合这些表征结果推测出 HABS分子可以沿着β-环糊精的内腔径向大、小口径端2个方向进入β-环糊精的内腔并形成了稳定的包结物包结物中HABS与β-环糊精之间的相互作用是β-环糊精降低强干扰体系中HABS紫外光谱干扰的主要原因。

    • 摘要: 本文通过紫外吸收光谱法研究了落新妇苷与β-环糊精(β-CD)的包结反应.β-CD可与落新妇苷形成1:1包结物,并使其在291 nm处吸光度有规律下降,二者包结平衡常数为1788.54±273.41M-1.采用研磨法制备落新妇苷与β-CD的包结物,考察了水分含量和摩尔比对落新妇苷包结率的影响.适当提高研磨过程中水份含量和β-CD摩尔比可增加落新妇苷包结率.最后,比较了β-CD包结物和落新妇苷单体的溶解度、体外溶出度和大鼠体内生物利用度.形成β-CD包结物可显著提高落新妇苷溶解度.25°C条件下,包结物中落新妇苷的溶解度为52.01mM,为落新妇苷单独存在时的106.14倍.体外溶出度曲线表明包结物中落新妇苷的溶解速度更快.包结物中落新妇苷在大鼠体内达到峰值时间更短,且峰值浓度更高,但二者生物利用度相当,绝对生物利用度都约为3.7%.

    • 摘要: A novel enhanced ultraviolet absorption spectrometry method was developed for the quantitative analysis of SDBS induced by β-cyclodextrin(β-CD) with strong interferences.The ultraviolet absorption spectra of SDBS indicated that the presence of β-CD could result in the enhancement of absorption intensities of SDBS.A good linearity was obtained between the UV-absorption intensity of the system and the concentration of SDBS.The results indicated that the determination precision and the determination ranges of SDBS could be greatly improved by β-CD.The effect of several common interfering substances(SDS,OP-10,HPAM) on the determination of SDBS could be significantly reduced in β-CD aqueous solution.Therefore,the maximum errors of the determined SDBS were less than 2.0% under multifactor interferences,and the precision of the method was also as high as 10-2 ~10-3 mg · L-1.The stable inclusion of β-CD and SDBS could be automatically formed in water with molar ratio of 1 ∶ 1.The stability constant of the inclusion,Ka,was 87 and the standard Gibbs function of molar reaction,AγGm(o) (298 K),was-11.064 kJ · mol-1.FTIR analysis exhibited that SDBS could be induced by β-CD since the phenyl group in SDBS molecule could exist stably in the cavity of β-CD and form the inclusion.%采用β-环糊精诱导SDBS产生显著增强的激发光谱信号,通过激发的光谱信号与SDBS含量的对应关系定量存在较强干扰作用时的SDBS水溶液.研究结果表明,β-环糊精具有显著提高SDBS的检测范围和检测精度的作用,同时具有显著降低三采复配驱油剂中SDS、OP-10及HPAM等常用组分对SDBS定量产生的干扰影响.该方法的定量误差在2.0%以下,检测精度可达10-2~10-3 mg·L-1.在水溶液体系中,β-环糊精可自发与SDBS形成摩尔比为1∶1型包结物,该包结物的吉布斯函变AγGm(o) (298 K)为-11.064kJ·mol-1,稳定常数Ka为87.结合FTIR分析推测出SDBS分子中苯环基团进入β-环糊精空腔内部形成稳定的包结物,是其产生激发光谱的根本原因.

    • 摘要: Poor solubility of lipophilic bioactive substances, pigments and flavors is a severe obstacle for their applications in hydrophilic food systems. Cyclodextrin has a particular molecular structure with a hydrophilic exterior surface and a nonpolar interior cavity, which can contribute to its application in forming inclusion complexes with the above substances to improve their solubility and broaden their applications. In this article, on the basis of cyclodextrin inclusion mechanisms and other factors, the enhancing effect of cyclodextrin inclusion technique on the solubility of hydrophobic bioactive substances, pigments and flavors is reviewed. Its application in the removal of unwanted components in foods and its future prospect in the food industry are also discussed.%脂溶性生物活性物质、色素和风味剂的溶解特性严重限制了其在亲水性食品体系中的应用。具有特殊分子结构(内疏水,外亲水)的环糊精能与这些物质形成包结物,提高它们在水中的溶解度(增溶作用),从而大大拓展使用范围。本文在介绍环糊精包结增溶原理及其影响因素的基础上,对该技术在水不溶性生物活性物质、色素、风味剂、食品添加剂等增溶以及食品中嫌嫉成分去除中的应用进行综述,并对该技术的发展前景进行展望。
