| Abstract: |
| Lycium barbarum L. fruits were stored for 10 days in ambient temperature to study changes of fruit decay, cell wall components and activity of pectin-degrading enzyme in relation to their texture. The results show that fruit decay began decreasing 2 days after harvest and the most rapid period was 8～10 days after harvest. During the period of storage, the contents of water-soluble pectin (WSP) followed the high-low-high trending. and Ionic bond pectin increased. Significant positive correlation was observed between WSP, Ionic bond pectin and fruit decay index. The content of covalent bond pectin followed the low-high-low tr
ending, was negatively with fruit decay index. The contents of cellulose and hemicellulose were decreased, was significant positive correlation with fruit decay index. Pectinmethylesterase (PME) activity was decreased, was significant negatively correlation with fruit decay index. Polygalacturonase(PG) activity followed the low-high-low trending, was negatively correlation with fruit decay index. |
