The aim of this study was to treat enzymes with high pressure or magnetic field, and to evaluate their storage stability after treatment. The application of a magnetic field of 1.34 T increased the lysozyme activity about 55%, while a treatment with 0.7 T increased 80% the Candida antarctica lipase B (CALB) activity. After the magnetic treatment, the residual activity was maintained above 140% for lysozyme and CALB at 4 °C, showing good stability after treatment. Furthermore, lysozyme treated with supercritical CO₂ had lower decrease on activity during storage, compared to others gases, maintaining residual activity over 100%.

高压和磁场处理对鸡蛋中南极假丝酵母脂肪酶B（CALB）和溶菌酶稳定性的影响

这项研究的目的是在高压或磁场下处理酶，并评估其在处理后的储存稳定性。施加1.34 T的磁场可使溶菌酶活性增加约55％，而使用0.7 T的处理则使80％的南极假丝酵母脂肪酶B（CALB）活性增加。磁处理后，溶菌酶和CALB的残留活性在4°C时保持在140％以上，显示出良好的稳定性。此外，与其他气体相比，用超临界CO ₂处理过的溶菌酶在储存过程中活性降低程度更低，残留活性保持在100％以上。
