The process flow and operating points of the quick-frozen corn section are as follows:
(1) The process flow is
Raw materials: removing buds and beards - selection - blanching - cooling and quick freezing - packaging and refrigeration
(2) Operation points: Remove the bracts and beards from the fresh corn ears, select the ears without insect holes for blanching, and boil them in boiling water for 8 minutes. You can add 5% salt and 2.5% citrate acid to the blanching water to make the flavor and color better. Then cool it quickly (use ice water or normal temperature water to cool down), drain the water, and place it at -25°C to -35°C for quick freezing. The freezing time is suitable for the entire ear of corn to be frozen solid. Pack it with composite film (single ear packaging or 2 to 3 ear packaging), seal, and freeze at -18°C.
