中文摘要: 以灵武长枣为试材,(0±0.5)℃为对照组(CK),研究(-1±0.1)℃、(-0.5±0.1)℃和(0±0.1)℃温度下灵武长枣品质的变化。结果表明,保鲜效果(-0.5±0.1)℃>(0±0.1)℃>(-1±0.1)℃>CK。其中,(-0.5±0.1)℃综合保鲜效果最佳。贮藏60 d,-0.5℃灵武长枣的果肉硬度、可溶性固形物(soluble solids,TSS)、抗坏血酸(ascorbic acid,VC)、可滴定酸(titratable acid,TA)分别为 11.2 kg/cm2、19.3%、289.5 mg/g、0.30%,优于 0℃;而-1℃出现冷害现象;但 CK 品质最差。

Abstract:Lingwu long jujubes were used as the test materials to study the storage characteristics of treatments at(-1±0.1)℃,(-0.5±0.1)℃,(0±0.1)℃,and(0±0.5)℃(CK)as control.Results showed that the preservation effects were (-0.5±0.1)℃>(0±0.1)℃>(-1±0.1)℃>CK,among those,the optimum temperature was (-0.5±0.1)℃.Under the 60 d,-0.5 ℃,the Lingwu long jujubes'firmness,soluble solids(TSS),ascorbic acid(VC),and titratable acid(TA)were 11.2 kg/cm2,19.3%,289.5 mg/g and 0.30%respectively,better than 0 ℃.Other than,-1℃did occur chilling injury phenomenon.And the quality of CK was the worst.
