In this study, an encapsulation system was developed for functional plant oil delivery. Through a series of orthogonal experiments and single factor experiments, the raw material compositions, emulsification conditions, and spray drying conditions for the preparation of flaxseed oil and safflower seed oil powders were optimized, and the final encapsulation efficiency was as high as 99% with approximately 50% oil loading. The storage stability experiments showed that oil powder's stability could maintain its physicochemical properties over six months. Oral supplementation of the spray-dried flaxseed oil powder exhibited a significant and better effect than flaxseed oil on alleviating colitis in C57BL/6J mice. It suppressed the pro-inflammatory cell factors, including IL-6 and TNF-α, and repaired gut microbial dysbiosis by increasing the microbial diversity and promoting the proliferation of probiotic taxa such as . This work suggests that spray-dried flaxseed oil powder has great potential as a nutraceutical food, with spray drying being a good alternative technique to improve its bioactivity.
在本研究中,开发了一种用于功能性植物油递送的包封系统。通过一系列正交实验和单因素实验,优化了制备亚麻籽油和红花籽油粉末的原料组成、乳化条件和喷雾干燥条件,最终包封效率高达99%,含油率约为50%。储存稳定性实验表明,油粉的稳定性可在六个月内保持其理化性质。口服喷雾干燥的亚麻籽油粉对缓解C57BL/6J小鼠的结肠炎具有显著且优于亚麻籽油的效果。它抑制了包括IL-6和TNF-α在内的促炎细胞因子,并通过增加微生物多样性和促进益生菌类群(如 )的增殖来修复肠道微生物失调。这项工作表明,喷雾干燥的亚麻籽油粉作为一种营养食品具有巨大潜力,喷雾干燥是提高其生物活性的一种良好替代技术。
