The substitution of margarine with candelilla wax (CW)-based oleogel is currently a prominent focus of research in the bakery industry. However, the use of CW-based oleogel in cookies increased starch digestibility, potentially posing a risk to human health. Thus, the anti-enzymatic mechanism of lipid-amylose complexes was used to evaluate the influence of olive diacylglycerol stearin (ODS) on starch digestibility in CW-based oleogel cookies. The in vitro digestibility analysis demonstrated that the DCW/ODS-35 cookie exhibited a increase of 27.72 % in slowly digestible starch (SDS) and resistant starch (RS) contents, compared to cookie formulated with margarine. The in-vivo glycemic index analysis revealed that the DCW/ODS-35 cookie had a medium glycemic index of 68. XRD pattern suggested that the presence of ODS in oleogels facilitated the formation of lipid-amylose complexes. The DSC analysis revealed that the addition of ODS resulted in the gelatinization enthalpy of DCW-based cookies increased from 389.9 to 3314.9 J/g. The FTIR spectra indicated that the combination of ODS could promote a short-range ordered structure in DCW-based cookies. Overall, these findings demonstrated that the utilization of DCW-based oleogel presented a viable alternative to commercial margarine in the development of CW-based cookies with reduced starch digestibility.
目前,用角鲨烷蜡(CW)基油凝胶代替人造黄油是烘焙行业研究的一个重点。然而,在饼干中使用 CW 基油凝胶会增加淀粉的消化率,这可能对人类健康构成风险。因此,人们利用脂质-直链淀粉复合物的抗酶解机制,评估橄榄油酰基甘油硬脂酸酯(ODS)对 CW 基油凝胶饼干中淀粉消化率的影响。体外消化分析表明,与用人造黄油制成的饼干相比,DCW/ODS-35 饼干中缓慢消化淀粉(SDS)和抗性淀粉(RS)的含量增加了 27.72%。体内血糖指数分析表明,DCW/ODS-35 饼干的血糖指数为中等,为 68。XRD 图谱表明,ODS 的存在促进了油凝胶中脂质-直链淀粉复合物的形成。DSC 分析表明,ODS 的添加使 DCW 基饼干的糊化焓从 389.9 增加到 3314.9 J/g。FTIR 光谱表明,ODS 的结合可以促进 DCW 基饼干中短程有序结构的形成。总的来说,这些发现表明,在开发 CW 基饼干时,使用 DCW 基油凝胶代替商业人造黄油是一种可行的选择,可以降低淀粉的消化率。
