Abstract

An optimized activated clay (ACL) bleaching process was developed for ‘Shenqiuhong’ sea buckthorn pulp oil (SPO). Among the four tested adsorbents, ACL showed the highest chlorophyll removal efficiency. Single-factor experiments and response surface methodology were applied to optimize key variables (dosage, temperature, and time). The optimal conditions (6.9 % ACL, 73 °C, 36 min) reduced chlorophyll by 84.6 %, while maintaining the fatty acid profile and improving visual quality. Levels of peroxide, moisture, phosphorus, and heavy metals were also significantly decreased. Although partial loss of phenolics and flavonoids occurred, the oil preserved considerable bioactivity. To our knowledge, this is the first comprehensive optimization of ACL bleaching for SPO, demonstrating a scalable method to improve oil quality and stability, and providing a technical reference for its use in functional foods, nutraceuticals, and cosmetics.

沙棘纸浆油活性粘土漂白工艺强化

研究了一种优化的活性粘土（ACL）漂白‘神秋红’沙棘纸浆油的工艺。4种吸附剂中，ACL对叶绿素的去除效率最高。采用单因素实验和响应面法对关键变量（剂量、温度和时间）进行优化。最佳条件（6.9% ACL, 73°C, 36 min）使叶绿素降低84.6%，同时保持脂肪酸分布并改善视觉质量。过氧化氢、水分、磷和重金属的含量也显著降低。尽管酚类和类黄酮发生了部分损失，但油保留了相当大的生物活性。据我们所知，这是第一次对SPO进行ACL漂白的全面优化，展示了一种可扩展的方法来改善油脂质量和稳定性，为其在功能食品、保健品和化妆品中的应用提供了技术参考。

期刊介绍： LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
