In this study, a steam explosion pretreatment method was established to prepare tuna bone powder. The conditions were optimized such that steam pressure of 0.6 MPa, reaction time of 5 min, and sample weight of 100 g. The result showed that steam explosion pretreatment would not change the chemical structure of bone powder, however, the median particle size (D) of the steam explosion pretreated tuna bone powder (SE-TBP) (13.186 μm) was significantly smaller than that of normal biological calcium tuna bone powder (N-TBP) (169.762 μm). The calcium absorption rate (79.75 ± 2.33%) and utilization rate (78.75% ± 2.85%) of the mice fed with SE-TBP were both higher than those of fed with CaCO or N-TBP with the same calcium equivalent in the feed. The steam explosion pretreatment method could obtain ideal tuna bone powder in a shorter time, provide a method for deep processing and utilization of tuna bone by-product.
本研究采用蒸汽爆破预处理方法制备金枪鱼骨粉。优化条件为蒸汽压力 0.6 MPa、反应时间 5 min、样品重量 100 g。结果表明，蒸汽爆破预处理不会改变骨粉的化学结构，但蒸汽爆破预处理金枪鱼骨粉（SE-TBP）的中值粒径（D）（13.186 μm）显著小于普通生物钙金枪鱼骨粉（N-TBP）（169.762 μm）。饲料中添加相同当量钙时，饲喂 SE-TBP 的小鼠的钙吸收率（79.75±2.33%）和利用率（78.75%±2.85%）均高于饲喂 CaCO 或 N-TBP 的小鼠。该蒸汽爆破预处理方法可在更短的时间内获得理想的金枪鱼骨粉，为金枪鱼骨副产物的深加工和利用提供了一种方法。
