摘要:【目的】以新疆三个红枣品种灰枣、河北脆枣、骏枣为试验材料,研究直接冷藏、保鲜袋+冷藏对鲜枣保
鲜效果的影响及红枣货架期期间品质。【方法】研究其贮藏期间(0—49 d)在贮藏温度o℃、相对湿度90%一
95%的不同处理条件下贮藏品质(质量损失、腐烂率、外观、硬度、可溶性固形物、总酸含量、VC含量、多酚氧化
酶活力、还原糖含量)的变化和货架期(1—7 d)贮藏品质(质量损失、腐烂率、外观、感官、硬度、可溶性固形物
含量)的变化。【结果】在整个贮藏期间,两个不同处理方式下,三个品种枣重量、硬度、VC含量呈现缓慢下降
趋势,而可溶性固形物、总酸、还原糖含量则呈现缓慢上升趋势;多酚氧化酶活力呈现不规律的趋势;而保鲜袋
+冷藏处理能较好的保持鲜枣的总酸、硬度、VC、重量损失情况;在货架期期间,两个不同处理方式下,三个品
种枣重量、硬度、可溶性固形物含量呈现缓慢下降趋势,且保鲜袋+冷藏处理能较好的保持鲜枣的硬度、重量
损失、可溶性固形物含量情况。【结论】就三个品种而言,灰枣和河北脆枣较耐贮藏,更适于进行保鲜;就两种
处理而言,保鲜袋+冷藏处理更适用于鲜枣的保鲜。

Abstract:【Objective】In
order
investigate the
effects of cold storage and storage bag+cold storage
the
storability of Chinese jujubes during storage and shelf—life period,Hui—jujubes,Jun—jujubes and Hebei cui—
jujubes
used
main experiment
material.【Method】In
this
paper,quality characters such
mass
loss
rotting rate,appearance,firmness,the soluble solid,total acid,VC,PPO activity
and reducing sugar content were
studied under 0。C storage temperature and 90%一95%relative humidity in storage experiment(between 0—49
d),and quality characters such as
mass
loss rate,rotting rate,appearance,sensory,firmness,the soluble solid
were
