Interactions between aroma compounds (d-limonene, ethyl hexanoate, octanal and 1-hexanol) and high amylose cornstarch were studied using inverse gas chromatography. Free energies of adsorption (deltaGa) and enthalpies of adsorption (deltaHa) of aroma compounds on starch were measured in the temperature range of 33-40 degrees C. The results showed existence of interactions between aroma compounds and starch, involving hydrogen bounds and dipole-dipole interactions. Sorption isotherms and Henry's law solubility coefficients (S) were determined at 40 degrees C. Three different shapes of isotherms were obtained according to the BET classification: type III for d-limonene, type II for ethyl hexanoate and linear for octanal and 1-hexanol.
利用反相气相色谱法研究了香气化合物（d-柠檬烯、己酸乙酯、辛醛和1-己醇）与高直链玉米淀粉之间的相互作用。在33-40℃的温度范围内测量了香气化合物在淀粉上的吸附自由能（ΔGa）和吸附焓（ΔHa）。结果表明，香气化合物与淀粉之间存在相互作用，涉及氢键和偶极-偶极相互作用。在40℃下测定了吸附等温线和亨利定律溶解度系数（S）。根据BET分类得到了三种不同形状的等温线：d-柠檬烯为III型，己酸乙酯为II型，辛醛和1-己醇为线性。
