【中文摘要】 利用高压静电解冻的方法,研究不同解冻场强、解冻时间和解冻温度对速冻冬枣解冻品质的影响。结果表明:高压静电解冻效果优于自然解冻,高压静电解冻后,冬枣硬度、含水量、有机酸含量、维生素C含量和可溶性糖含量均维持较高水平,汁液流失较少。适宜的解冻时间和解冻环境温度对解冻冬枣品质也有一定影响,适宜的解冻条件为18℃、100kV/m下解冻40min。
【英文摘要】 High voltage electrostatic field treatment was adopted to study the influences of high voltage electrostatic field, time and temperature on quality of thawing "Dongzao" jujube fruit. The experimental results show that the quality of thawing "Dongzao" fruit with high voltage electrostatic field treatment was better than that with natural thawing. The fruit hardness, water content, organic acid content, vitamin C and soluble sugar content were maintained at higher level while the juice loss was slight. Tawing time and temperature also affected the quality of thawing "Dongzao" fruit. Our results indicate that the suitable thawing parameters were 100kV/m, 18℃ and 40 min..
