Potato tubers tend to sprout during long-term storage, resulting in quality deterioration and shortened shelf life. Restrictions on the use of chlorpropham, the major potato sprout suppressant, have led to a need to seek alternative methods. In this study, the effects of methyl jasmonate (MeJA) solutions and MeJA microcapsules on sprouting and other key quality attributes of the potato tuber were investigated. The results showed that the MeJA solution was most effective at 300 μmol L according to TOPSIS analysis. To prepare MeJA microcapsules, the optimal formulation is with 0.04% emulsifier, 2.5% sodium alginate, 0.5% chitosan and 3% CaCl. Compared to 300 μmol L MeJA solution, MeJA microcapsules consumed a lower dose of MeJA but demonstrated a better retaining effect on the overall quality attributes of potato tubers. MeJA microcapsules are promising agents for the preservation of postharvest potato tubers.
土豆块茎在长期储存过程中容易发芽，导致品质下降和货架期缩短。由于对主要的土豆抑芽剂氯苯胺灵的使用限制，因此需要寻找替代方法。在这项研究中，研究了茉莉酸甲酯（MeJA）溶液和 MeJA 微胶囊对土豆块茎发芽和其他关键品质特性的影响。结果表明，根据 TOPSIS 分析，300μmol·L-1 的 MeJA 溶液效果最佳。为了制备 MeJA 微胶囊，最佳配方是使用 0.04%乳化剂、2.5%海藻酸钠、0.5%壳聚糖和 3%CaCl2。与 300μmol·L-1 的 MeJA 溶液相比，MeJA 微胶囊使用的 MeJA 剂量较低，但对土豆块茎整体品质特性的保持效果更好。MeJA 微胶囊是一种有前途的保鲜剂，可用于贮藏采后土豆块茎。
