QUALITY CHANGES IN SWEET CORN (Zea mays L. ssp. saccharata) cv. TROPHY F_1 UNDER VARIOUS STORAGE CONDITIONS

摘要

Problems of sweet corn storage include fast conversion of soluble sugars to starch and rapid water loss during kernel maturation, which occur soon after harvest. The corn loses its sweet taste and characteristic fragrance and becomes gummy in consistency. The possibility of longer storage of this vegetable emerged with the development of new high sugar corn cultivars. Compared to traditional cultivars, the new cultivars contain almost two times more sugar and show much weaker tendency for its conversion to starch (Geeson et al., 1991). The effect of temperature and packaging on dry matter, soluble sugars, and starch contents in kernels of one such cultivar Trophy F_1 (sh_2 hybrid) are examined here.
