Product Overview
Sweet corn canned food is a high-quality product made from fresh sweet corn cobs through systematic processes such as peeling, pre-cooking, threshing, cleaning, canning, and high-temperature sterilization. Available in both canning and bagging formats, the processing flow ensures maximum freshness and nutritional retention.
Processing Flow & Specifications
The processing sequence involves: Manual screening → Pre-cook → Cooling → Dedicated threshing → Initial washing → Sieving → Thread removal → Secondary cleaning → Canning → Juice injection → Vacuum sealing → High-temperature sterilization (128-130℃) → Final inspection.
1
Acceptance Criteria: Harvest with bracts on, avoiding direct sunlight. Processing must begin within two hours of harvest.
2
Peeling & Trimming: Corn should be spread in a cool place and peeled immediately. Time from harvest to processing should not exceed 6 hours.
3
Cleaning & Threshing: Thorough washing with running water followed by pelletizing with a dedicated corn chipper adjusted precisely for the cob.
4
Blanching: Immediate heat treatment at 95℃ to 100℃ for approximately 5 minutes using boiling water or steam.
5
Cooling: Segmented cooling method to reduce temperature from 90℃ down to below 5℃ quickly.
6
Selection: Manual sorting to remove discolored grains and impurities to ensure premium quality.
7
Quick Freezing: Uses a fluidized bed tunnel with high-speed cold air (6-8 m/s) to keep kernels suspended and free of surface frost.
8
Canning: Quantitative filling into tinplate cans, adding sugar water, sealing, pasteurization, and labeling.
