【摘要】 为解决果蔬速冻加工产品冻结时间长、易发生干耗的问题,该研究采用了高压二氧化碳技术(high pressure carbon dioxide,HPCD)对双孢菇进行了速冻。原料在热烫钝酶的基础上,通过单因素试验和正交试验,结合速冻产品感官评价试验对速冻工艺参数进行了优化。结果表明:HPCD速冻双孢菇最佳工艺参数为处理釜初温6℃、处理釜设定压力7MPa、卸压时间4min,且卸压时间为影响速冻产品品质最显著因素。HPCD速冻技术具有良好的工业化前景。更多还原

【Abstract】 In order to reduce freezing time and moisture loss of quick frozen fruits and vegetables,the HPCD(high pressure carbon dioxide) technology was used in quick freezing process of agaricus bisporus.Based on blanching treatments,single factor experiment,orthogonal experiment and sensory evaluation were designed to optimize the quick-freezing technology parameters.The results showed that the best sensory quality of the quick-freezing products could attain,when the pressure-relief time was 4 minutes and the initial temperature and setting pressure of the reaction vessel was 6℃,7 MPa,respectively.Moreover,pressure-relief time had the most significant influence on product quality.Industrialization prospect of HPCD(high pressure carbon dioxide) technology is suggested.更多还原
