Grower & exporter of white super-sweet fruit corn · Shandong, China
Frozen corn earns its bad reputation from slow freezing. We do the opposite — freeze fast enough that the kernel never knows it left the field.
When corn freezes slowly below 0°C, water inside the kernel migrates and forms a few large ice crystals. Those crystals grow against the cell walls and tear them. On thawing, the ruptured cells leak water and nutrients — the corn turns soft, watery and dull.
Quick-freezing changes the physics. By dropping the temperature to −35 to −40°C in moving air, water freezes almost instantly into countless tiny ice nuclei — each under 100 microns — spread evenly through the tissue. No large crystals form, so the cell walls stay whole. Thaw it, and the kernel keeps its shape, juice, colour and snap.
Slow freeze (0°C, hours)
Large ice crystals
Cell walls rupture · leaks water on thaw · loses flavour & texture
Our IQF (−35 to −40°C, instant)
Micro ice nuclei (<100 μm)
Cell walls intact · holds juice · preserves flavour & colour
Ears are picked at the green-ear stage, when sugar and tenderness are highest.
Husked, washed, graded and cut — kernels off the cob or cobs to length.
Product passes through moving air at −35 to −40°C and freezes in moments, not hours.
Free-flowing pieces are packed and held at −18°C through an unbroken cold chain.
