中长链三糖醇 (MLCT) 油凝被开发出来,与驼油 (CO) 油凝相比,由于不和LCFA较低,其机械强度和热稳定性降低. ML-SO证明了优越的网络形成.
科学领域:
- 食品科学 食品科学 食品科学
- 材料科学 材料科学 材料科学
- 生物化学 生化学
背景情况:
- 研究了从驼油 (CO) 和中链甘油中通过酶转化合成中长链三甘油 (MLCT).
- 开发了使用MLCT作为各种oleogelators (β-sitosterol/γ-oryzanol (SO),单甘油,卡纳乌巴) 的基板油的新型MLCT油基.
- 探索了MLCT在油凝结构内自我组装行为的调节机制.
研究的目的:
- 为了合成新的MLCT并构建MLCT油脂凝.
- 研究油中MLCT的自我组装机制.
- 与CO油脂油脂相比,评估MLCT油脂油脂的结构和热性能.
主要方法:
- 用于MLCT合成的酶转化.
- 使用MLCT和特定的油凝器制成的油凝配方.
- 油的风湿学,机械和热学分析.
主要成果:
- 与CO油相比,MLCT油具有较低的G',明显粘度,油结合能力和硬度.
- 在MLCT油基中,较低的键强度和分子间力量与减少的晶体含量和热稳定性相关.
- 由于减少了长碳链脂肪酸 (LCFA),MLCT油脂凝的卡路里含量较低.
- 在测试的MLCT油脂中,ML-SO油脂呈现出最强的网络,最高的机械强度和最佳的热稳定性.
结论:
- 将中链脂肪酸纳入甘的骨干削弱了oleogel网络结构.
- 这种减弱归因于合成的MLCT中的不和LCFA含量下降.
- 这些发现为开发低热量功能性塑料脂肪提供了一条途径.
