3. Core Processing Technology (Core of Quality, Highlighting Differentiation)
We adopt world-leading IQF individual quick freezing technology to ensure stable product quality.
The whole process complies with HACCP and ISO22000 international food processing standards.→To see food safety certifications
We,as a frozen bamboo shoot manufacturer, strictly control every link in the processing.
1. Raw Material Inspection and Pretreatment
We fully inspect all raw materials when they enter the factory.
Workers peel, trim and remove old roots manually.
We retain the highest quality part of the bamboo shoot flesh.
2. Grading and Screening
We grade the shoots automatically by diameter and length.
This ensures uniform specifications for products in the same batch.
We provide customized cutting according to needs, such as whole shoots, sections, slices, shreds and dices.
3. Cleaning and Sterilization
We clean the shoots with 3 rounds of flowing clear water.
We also use food-grade hypochlorous acid solution for spray sterilization.
This removes sediment, impurities and surface microorganisms.
4. Precise Blanching
We blanch the shoots at a constant temperature of 95-100℃.
We adjust the blanching time dynamically according to product specifications.
Its core functions include: inactivating polyphenol oxidase to prevent browning.
It kills harmful microorganisms and removes trace astringency.
It also locks in the crisp taste of the bamboo shoots.
5. Rapid Ice Water Cooling
We immediately send the blanched shoots to a 0-4℃ ice water circulation system for rapid cooling.
We lower the core temperature of the shoots to below 10℃ within 10 minutes.
This stops the thermal reaction and avoids softening caused by over-cooking.
6. IQF Ultra-Low Temperature Individual Quick Freezing (Core Process)
We use ultra-low temperature fluidized quick-freezing equipment below -35℃.
We lower the core temperature of the shoots to below -18℃ within 15 minutes.
This turns the water in the cells into micron-sized small ice crystals.
It does not damage the cell structure of the bamboo shoots, achieving the following effects:
- Juice loss rate after thawing ≤5%, which is much lower than the industry average of 8%.
- Crispness retention rate ≥90%, with almost the same taste as fresh Ma Bamboo shoots.
- Individual shoots do not stick to each other, so you can take as needed, fitting retail and industrial processing scenarios.
7. foreign impurity Control
We conduct 2 rounds of high-precision metal detection and X-ray foreign impurity detection.
This ensures no physical impurities in the products.
8. Aseptic Packaging and Warehousing
We complete the packaging in a 10,000-level clean workshop.
We immediately send the finished products to a constant temperature cold storage at -18℃ for storage.
