Hardy kiwifruits (Actinidia arguta) contain various bioactive compounds such as vitamin C and phenolics and can withstand cold temperatures. Changes in soluble solid, vitamin C, total phenolic, and total flavonoid content, and antioxidant capacity of three cultivars of hardy kiwifruits (A. arguta × A. deliciosa cv. Mansu, A. arguta cv. Haeyeon, and A. arguta cv. Chiak) were comparatively evaluated for 8 weeks of storage at 1 ± 0.5 °C. After the 8 weeks of storage, soluble solid content of three cultivars increased, whereas their vitamin C content decreased. Throughout this storage period, total phenolic and flavonoid content of cv. Mansu and cv. Haeyeon remained the same, while antioxidant capacity of these two cultivars also remained similar but with slightly more variations. Cv. Chiak, however, showed a decrease in total phenolic and flavonoid content and antioxidant capacity. These results suggest that cold storage of the hardy kiwifruits maintains levels of bioactive compounds.

耐寒猕猴桃（猕猴桃）含有多种生物活性化合物，如维生素 C 和酚类物质，可以抵御寒冷的温度。三个耐寒猕猴桃品种（A. arguta  ×  A. deliciosa cv. Mansu、A. arguta cv. Haeyeon和A. arguta）的可溶性固形物、维生素C、总酚和总黄酮含量以及抗氧化能力的变化简历。Chiak) 在 1 ± 0.5 °C 下储存 8 周进行了比较评估。贮藏8周后，三个品种的可溶性固形物含量增加，而维生素C含量下降。在整个储存期间，cv. 的总酚类和类黄酮含量。曼苏和简历。Haeyeon 保持不变，而这两个品种的抗氧化能力也保持相似，但略有不同。简历。然而，Chiak 的总酚类和类黄酮含量以及抗氧化能力有所下降。这些结果表明，耐寒猕猴桃的冷藏保持了生物活性化合物的水平。
