摘要
以蒜薹为试材,设置O2和CO2初始比例为70%O2+30%CO2、80%O2+20%CO2、90%O2+10%CO2、100%O2及自然空气(CK)5个处理,采用主动自发气调的方法,研究了在(20±0.5)℃贮藏温度下,蒜薹的生理生化、品质指标以及密封容器内CO2含量变化,以期为蒜薹的物流运输保鲜提供参考依据。结果表明:80%O2+20%CO2处理明显抑制蒜薹失重率和腐烂率的上升,延缓MDA积累和硬度下降,推迟可溶性固形物和色度H值高峰的出现,保持较高的抗坏血酸含量和叶绿素含量。70%O2+30%CO2和90%O2+10%CO2处理对蒜薹也有一定的保鲜效果,但保鲜效果不如80%O2+20%CO2处理。100%O2处理则加速了蒜薹的品质恶化。
Garlic bolts were used as materials,and the treatments of initial O2 and CO2 proportions including 70%O2+30%CO2,80%O2+20%CO2,90%O2+10%CO2,100%O2 and natural air(CK)were employed.Adopting active modified atmospheres way to study the change of physio-chemical indices and quality of Garlic bolts along with CO2 content in the sealed container,during storage at(20.0±0.5)℃.The results of this experiment could provide a theoretical basis for the short storage of Garlic bolts during logistics and transportation.The results showed that 80%O2+20%CO2 treatment significantly inhibited the increase of weight loss rate and rotting rate,delayed the accumulation of MDA and the decline of hardness,retarded the appearance of soluble solids and chroma H value peak,maintained high ascorbic acid and chlorophyll content.70%O2+30%CO2 and 90%O2+10%CO2 treatments also had a certain storage effect on Garlic bolts,but which was inferior to the treatment of 80%O2+20%CO2.Nevertheless,100%O2 treatment accelerated the deterioration of Garlic bolts.
