摘要

渔业的副产品/废物量约为 50%。鱼骨可用于生产纳米颗粒,作为一种新型钙源在食品工业中具有潜在用途,同时还有助于减少废物的产生。本研究的目的是评估纳米级鲑鱼骨颗粒与微米级鲑鱼骨颗粒和碳酸钙相比的生物利用率。研究在 21-28 天大的 C57BL/6 雄性小鼠中进行,用实验饮食喂养 21 天。各组情况如下CaCO3 0.5% Ca (CN 0.5);CaCO3 1.0% Ca (CN 1.0);鲑鱼骨微粒 0.5% Ca (MP 0.5);鲑鱼骨微粒 1.0% Ca (MP 1.0);鲑鱼骨纳米微粒 0.5% Ca (NP 0.5);鲑鱼骨纳米微粒 1.0% Ca (NP 1.0)。从 CN 0.5 到 NP 1.0 组,钙生物利用率(定义为股骨中钙的百分比)呈上升趋势。根据方差分析,与除 NP 0.5 以外的所有组别相比,NP 1.0 组的钙含量最高。总之,在小鼠模型中,鲑鱼骨纳米颗粒比鲑鱼骨微颗粒具有更高的钙生物利用率,而两者的生物利用率又都高于碳酸钙。

Fish Bones as Calcium Source: Bioavailability of Micro and Nano Particles
The amount of by-products/waste in the fish industry is roughly 50%. Fish bones could be used to produce nanoparticles, which may have potential use in the food industry as a novel calcium source and at the same time, contribute to reduce waste production. The objective of this study was to evaluate the bioavailability of nano-size salmon fish bone particles compared to micro-size salmon fish bone particles, and calcium carbonate. The study was carried out in 21–28-day-old C57BL/6 male mice fed for 21 days with the experimental diets. The groups were as follows: CaCO3 0.5% Ca (CN 0.5); CaCO3 1.0% Ca (CN 1.0); salmon fish bone (SFB) microparticles 0.5% Ca (MP 0.5); SFB microparticles 1.0% Ca (MP 1.0); SFB nanoparticles 0.5% Ca (NP 0.5); and SFB nanoparticles 1.0% Ca (NP 1.0). Calcium bioavailability, defined as the percent calcium in femur showed an increasing trend from CN 0.5 to NP 1.0 group. According to ANCOVA, the greatest Ca content was observed in the NP 1.0 group compared with all groups but NP 0.5. In conclusion, in a murine model, salmon fish bone nanoparticles present higher calcium bioavailability than salmon fish bone microparticles, and both, in turn, have better bioavailability than calcium carbonate.
