The objective of this study was to assess the effectiveness of functionalized bionanocompounds with ice nucleation protein (INP) as a novel approach for freezing applications in terms of how much energy is used during each step of freezing when water bionanocompound solutions were compared with pure water. According to the results of the manufacturing analysis, water required 28 times less energy than the silica + INA bionanocompound and 14 times less than the magnetite + INA bionanocompound. These findings showed that water used the least energy during the manufacturing process. In order to determine the associated environmental implications, an analysis of the operating stage was also conducted, taking the defrosting time of each bionanocompound during a 4 h work cycle into account. Our results showed that bionanocompounds may substantially reduce the environmental effects by achieving a 91% reduction in the impact after their use during all four work cycles in the operation stage. Additionally, given the energy and raw materials needed in this process, this improvement was more significant than at the manufacturing stage. The results from both stages indicated that, when compared with water, the magnetite + INA bionanocompound and the silica + INA bionanocompound would save an estimated 7% and 47% of total energy, respectively. The study's findings also demonstrated the great potential for using bionanocompounds in freezing applications to reduce the effects on the environment and human health.
本研究的目的是评估具有冰核蛋白（INP）的功能化生物纳米化合物作为一种新型冷冻应用方法的有效性，具体是比较水生物纳米化合物溶液与纯水在冷冻各步骤中所消耗的能量。根据制造分析结果，水所需的能量比二氧化硅+INA生物纳米化合物少28倍，比磁铁矿+INA生物纳米化合物少14倍。这些发现表明，水在制造过程中消耗的能量最少。为了确定相关的环境影响，还对运行阶段进行了分析，考虑了每个生物纳米化合物在4小时工作周期内的除霜时间。我们的结果表明，生物纳米化合物在运行阶段的所有四个工作周期使用后，可将影响降低91%，从而大幅减少环境影响。此外，考虑到该过程所需的能源和原材料，这种改善在运行阶段比在制造阶段更为显著。两个阶段的结果均表明，与水相比，磁铁矿+INA生物纳米化合物和二氧化硅+INA生物纳米化合物分别可节省约7%和47%的总能源。该研究的结果还表明，在冷冻应用中使用生物纳米化合物具有巨大潜力，可减少对环境和人类健康的影响。
