不同产地“红富士”苹果的采后品质及软化

Postharvest quality and softening of “Fuji” apple from different production areas

  • 摘要: 本试验对河北省辛集、顺平和平山3地生产的“红富士”苹果品质及其软化进行了研究, 结果表明:与顺平和平山产苹果相比, 辛集产苹果贮期内硬度较低, 可溶性果胶含量增加较为迅速, b-半乳糖苷酶在贮存84 d内一直保持较高活力, 较早表现出衰老和软化;相对而言, 顺平产苹果在贮期内硬度下降以及可溶性固形物和可溶性果胶含量增加缓慢, b-半乳糖苷酶活性较低, 软化衰老较慢;平山产苹果在贮藏126 d后硬度明显下降, 可溶性果胶含量明显增加, b-半乳糖苷酶活性在贮藏126 d前高于顺平产苹果, 但低于辛集产苹果, 126 d后显著高于其他两地, 软化衰老加快。

     

    Abstract: Studies on the postharvest quality and softening of “Fuji” apple from Xinji, Shunping, and Pingshan of Hebei Province were conducted. Compared with apples from Shunping and Pingshan, fruits produced in Xinji presents lower rigidity, with a rapid increase in water-soluble pectin content and higher activity of b-galactosidase during 84 days of storage. Apples produced in Xinji exhibit earlier senescence and softening. However, apples produced in Shunping soften and age comparatively slower due to gradual loss of rigidity, tardy increase in soluble substance content, water-soluble pectin content and much lower β-galactosidase activity. After 126 days of storage, rigidity of apples produced in Pingshan markedly declines, water-soluble pectin content increases more rapidly, and β-galactosidase activity markedly heightens than those from the other two regions, though higher than those from Shunping and lower than those from Xinji prior to 126 days of storage.
