ABSTRACT Seabream fish bone powder was produced using different chemical methods and tap water. The effect of different chemical procedures (sodium hydroxide (NaOH); NaOH + citric acid; NaOH + sodium hypochlorite (NaOCl); NaOH + ethanol (EtOH); and NaOH + hydrogen chloride (HCl)) and tap water on proximate composition, yield, mineral composition, color, and sensorial odor was investigated. Despite its high bone powder yield (59.39%), tap water treatment was not an efficient method due to low calcium (Ca2+, 232.13 g/kg) and phosphorus (P, 111.63 g/kg) concentration and heavy fish odor. Sensorial odor analysis of seabream fish bone powder showed that tap water received the lowest scores (1.71/5), while chemically treated samples received sensorial odor scores higher than 4.00, with an average of 4.61, indicating that they had a very slight odor. The best fish bone powder yield was obtained using NaOH treatment (21.46%), where Ca2+ (276.73 g/kg) and P (147.23 g/kg) content was also high. The utilization of chemicals in combination with NaOH did not increase the sensorial odor score of seabream fish powders but resulted in a decrease in powder yield. Moreover, the mineral composition of all chemical processing techniques was comparable. Processing by-products of seabream fillet production with 8% NaOH will contribute to daily Ca2+ and P intake of individuals.

处理方法会影响来自鱼片副产品的鲷鱼 (Sparus aurata) 鱼骨粉的颜色、化学成分和矿物质成分

摘要 鲷鱼鱼骨粉是使用不同的化学方法和自来水生产的。不同化学程序（氢氧化钠 (NaOH)；NaOH + 柠檬酸；NaOH + 次氯酸钠 (NaOCl)；NaOH + 乙醇 (EtOH)；以及 NaOH + 氯化氢 (HCl)）和自来水对近似组成、产率的影响、矿物成分、颜色和感官气味进行了研究。尽管其骨粉产量高 (59.39%)，但由于钙 (Ca2+, 232.13 g/kg) 和磷 (P, 111.63 g/kg) 浓度低以及鱼腥味重，自来水处理并不是一种有效的方法。鲷鱼鱼骨粉的感官气味分析表明，自来水的得分最低（1.71/5），而化学处理的样品的感官气味得分高于4.00，平均为4.61，表明它们有非常轻微的气味。使用 NaOH 处理获得最佳鱼骨粉产量 (21.46%)，其中 Ca2+ (276.73 g/kg) 和 P (147.23 g/kg) 含量也很高。化学物质与 NaOH 结合使用不会增加鲷鱼粉的感官气味评分，但会导致粉末产量下降。此外，所有化学加工技术的矿物成分都具有可比性。用 8% NaOH 加工鲷鱼片生产的副产品将有助于个人每日 Ca2+ 和 P 的摄入量。所有化学加工技术的矿物成分都具有可比性。用 8% NaOH 加工鲷鱼片生产的副产品将有助于个人每日 Ca2+ 和 P 的摄入量。所有化学加工技术的矿物成分都具有可比性。用 8% NaOH 加工鲷鱼片生产的副产品将有助于个人每日 Ca2+ 和 P 的摄入量。
