Industry Pain Points Direct Hit: Fermented and Deformed Corn After High-Temperature Sterilization? How to Solve the Dilemma of Fresh Corn Processing with Three-Side Seal Corn Stick Steaming Bags

[Click to Get] "Fresh Corn Barrier Requirements Map" + Customized Test Package

Soul Questioning: Why Does Sterilized Corn Always Lose Its Appearance and Flavor?

"High-pressure steaming causes corn kernels to collapse and sugar loss. Can imported equipment solve it?" Traditional vacuum packaging due to internal pressure imbalance and barrier defects leads to:

1. Bag Burst Rate > 5% after steaming (according to the research data of the Chinese Academy of Agricultural Sciences), resulting in ton-level production capacity loss;

2. Shelf Life Acidification Rate: The taste of ordinary packaging deteriorates by more than 40% in 3 months;

3. Undercooked Hidden Danger: Uneven heating causes the center sterilization value (F0) to fluctuate by 38%.

"Difference in Barrier Requirements for Corn Sticks of the Same Kind Reaches 27 Times?" According to the detection of 112 corn varieties by COFCO Research Institute:

1. Sweet Corn with sugar content > 18%: Oxygen transmission rate ≤ 0.5 cm³/m²·day (2.6 times stricter than ordinary corn);

2. Black Glutinous Corn with anthocyanin content > 50 mg/100g: Ultraviolet barrier rate needs to reach 98% and light-proof packaging;

3. Fruit Corn with free water content > 33%: Water vapor barrier needs to be ≤ 3 g/m²·day.

Sterilization Process Adaptation for Sweet Corn

Packaging parameters after high-temperature steaming (121°C/40 min):

• Vacuum degree maintained ≥ -85 kPa, film separation rate < 0.8%;

• Grain integrity: 97.3% for three-side seal bags VS 72.6% for traditional bags.

Light Sensitivity Experiment of Black Corn

Storage comparison under 4000 lux light (room temperature for 30 days):

• Ordinary transparent bags: Anthocyanin loss of 39%;

• Three-side seal silicon-coated bags: Anthocyanin loss of 8.7%.

Six-Step Precise Selection Guide

1. Variety Traceability → Query variety patent number → Retrieve growth cycle moisture curve;

2. Sterilization Intensity → F0 value calculation → Match film material temperature resistance parameters;

3. Logistics Scenario → Cold chain duration → Design target OTR/WVTR value;

4. Terminal Selling Point → Transparent visibility requirement → Choose haze ≤ 3% or light-proof solution;

5. Sealing Process → Equipment type → Adjust heat flow index (MFI) of hot melt adhesive;

6. Environmental Demand → Choose recyclable structure RCPP/PET composite material.
