Transport Precautions for L-Threonine

During the transportation of L-Threonine, it is essential to consider its chemical properties and potential environmental factors to ensure the quality and safety of the product. Below are some key transportation guidelines:  

Ⅰ. Packaging Requirements  

1. Selecting Appropriate Packaging Materials:  

  ·L-threonine is typically packaged in woven bags with inner plastic lining, fiber drums, or other sealed containers.  

  ·The inner packaging should be made of food-grade plastic bags, which provide moisture-proof and oxidation-resistant properties, ensuring the product remains unaffected by external conditions during transportation.  

  ·The outer packaging must be sturdy and pressure-resistant. For example:  

     ·Woven bags should have sufficient strength.  

     ·Fiber drums should be thick, intact, and undamaged to protect the inner packaging from compression.  

2. Sealing Inspection:  

·Before transportation, thoroughly check the packaging for proper sealing to prevent leakage.  

·Even minor leaks can lead to moisture absorption, contamination, or product loss, which is especially critical for long-distance or multi-environment transportation.  

Ⅱ. Loading and Unloading Operations  

1. Handle with Care:  

·L-Threonine should be handled gently to prevent damage to the packaging.  

·Avoid dropping, colliding, or applying excessive force, as physical damage may affect the product’s appearance and quality.  

2. Proper Stacking:  

·During loading and unloading, stack the packages according to their shape, weight, and load-bearing capacity.  

·Do not stack too high, as excessive pressure may damage the bottom layer of packaging.  

·Ensure stable stacking to prevent cargo from collapsing during transportation.  

Ⅲ. Transportation Environment  

1. Temperature Control:  

·The recommended transport temperature for L-Threonine is ambient temperature, but extreme heat and cold should be avoided.  

2. In hot summer conditions:  

·Use shaded transport vehicles or schedule shipments during cooler hours (early morning or evening).  

·If necessary, use refrigerated transport to keep the temperature below 25°C.  

3. In cold winter conditions:  

·Take insulation measures to prevent freezing.  

·The transportation environment should be maintained above -5°C to avoid potential structural or physical changes in the product.  

4. Humidity Control:  

·The relative humidity during transportation should be kept below 60% to prevent moisture absorption and clumping.  

·Moisture-absorbing agents, such as silica gel or quicklime (calcium oxide), can be placed in transport vehicles or containers.  

·If transporting through high-humidity areas or rainy weather, ensure that vehicles or containers are well-sealed to prevent water intrusion.  

5. Avoid Light Exposure:  

·L-Threonine should be protected from direct sunlight and strong light exposure.  

·Use covered transport vehicles, such as box trucks or shipping containers, to ensure a light-protected environment.  

6. Prevent Contamination:  

·L-Threonine must not be transported alongside toxic, hazardous, odorous, or easily contaminated substances such as pesticides, fertilizers, or chemical raw materials.  

·Transport vehicles and containers must be kept clean and sanitized before loading.  

·Perform a thorough cleaning and disinfection before use to eliminate residual contaminants from previous cargo.  

Ⅳ. Transport Documentation & Labeling  

1. Complete Transport Documents:  

·The following essential documents must be carried during transportation:  

  ·Cargo inventory list  

  ·Quality inspection report  

  ·Transport contract  

·These documents facilitate inspections during transit and ensure legal compliance and product traceability.  

2. Clear Labeling:  

·The packaging should be clearly labeled with:  

  ·Product name  

  ·Specifications  

  ·Quantity  

  ·Production date & shelf life  

  ·Handling and transportation precautions  

·Proper labeling helps ensure accurate identification and handling of the cargo and streamlines the receiving process for the consignee.  

By following these transportation guidelines, the quality, stability, and safety of L-Threonine can be effectively maintained throughout the shipping process.
