摘要: 本研究采用pH值驱动法,构建罗非鱼肌原纤维蛋白(tilapia myofibrillar protein,TMP)/κ-卡拉胶寡糖(κ-carrageenan oligosaccharide,κCOS)纳米复合物,并对姜黄素(curcumin,CUR)进行包载,以解决CUR低生物利用度和性质不稳定性的问题。该纳米复合物在其在最佳质量浓度条件下(TMP 12 mg/mL、κCOS 4 mg/mL)制备的纳米复合物粒径为(291.16±5.37)nm,Zeta电位为(-29.80±1.67)mV,多分散系数为0.34±0.04。TMP/κCOS纳米复合物形成了三维网状结构;当CUR在纳米复合物中质量浓度达到2 mg/mL时,可有效包载于纳米复合物中,且获得较高的包载率((76.76±0.04)%)。红外光谱和圆二色光谱结果表明,TMP与κCOS通过静电作用和疏水相互作用结合,且结合后α-螺旋含量显著增加,由22%(TMP)增加至76%(TMP/κCOS)。体外释放结果表明,TMP/κCOS/CUR复合物在60 min时的CUR释放率仅为(14.43±0.85)%,在180 min时的CUR释放率可达(74.71±0.70)%。该纳米复合物可有效提高CUR的离子稳定性及热稳定性。本研究可为TMP/κCOS纳米递送系统的构建提供可靠工艺,也表明其在疏水性活性成分递送领域具有良好应用潜力。

Abstract: In this study, the pH-driven method was employed to construct tilapia myofibrillar protein (TMP)/κ-carrageenan oligosaccharide (κCOS) nanocomplexes for encapsulating curcumin (CUR), aiming to address the issues of its low bioavailability and poor stability. The nanocomplex prepared under optimized conditions (TMP concentration = 12 mg/mL, κCOS concentration = 4 mg/mL) had the following properties: an average particle size of (291.16 ± 5.37) nm, a zeta potential of (−29.80 ± 1.67) mV, and a polydispersity index (PDI) of 0.34 ± 0.04. Furthermore, the nanocomplex formed a three-dimensional network structure. At a concentration of 0.2 mg/mL, CUR could be effectively loaded into the nanocomplex, with a high loading rate of (76.76 ± 0.04)%. The results of infrared (IR) and circular dichroism (CD) spectroscopy indicated that TMP and κCOS were combined through hydrophobic and electrostatic interactions, and the content of α-helix significantly increased after binding, from 22% (TMP) to 76% (TMP/κCOS). The in vitro release results indicated that the cumulative release rate of CUR from the TMP/κCOS/CUR complex was only (14.43 ± 0.85)% after 60 min, while it reached (74.71 ± 0.70)% after 180 min. This nanocomplex could effectively improve the ionic and thermal stability of CUR. This study provides a reliable process for the construction of TMP/κCOS nano-delivery systems and also indicates its good application potential in the field of hydrophobic active ingredient delivery.
