摘要:

以新鲜海参为研究对象,通过单因素试验和正交试验对影响海参中微生物存活率的工艺参数(压力、pH值、保压时间)进行考察和评价;对比两种加压方式对保鲜效果的影响,确定超高压处理海参的最佳工艺条件。实验结果表明:处理压力300~500MPa、保压时间10~30min、pH6.1~6.9 对海参中各种微生物杀灭作用显著。最终确定采用循环加压、压力500MPa、保压时间30min、pH6.5 作为海参超高压保鲜的最佳工艺。

Abstract:

Effects of processing pressure, pH and pressure duration on the total bacterial count of fresh sea cucumber were investigated by single factor test, and then these factors were optimized by orthogonal test design. Moreover, fresh-keeping effects of two pressure modes, namely continuous and cycle pressure modes, were compared. The results showed that under the conditions of the processing pressure 500 MPa, pH 6.5 and pressure duration 30 min, the best sterilization effect on fresh sea cucumber was achieved, and the fresh-keeping effect of the cycle pressure mode was superior to that of another mode .

Key words: ultrahigh pressure, fresh sea cucumber, sterilization, pressure
