To ensure the safety of using L-threonine raw materials in infant formulas, strict control is required from multiple aspects. The following are the specific measures:
I. Raw Material Procurement and Quality Control
Select high-quality suppliers: Cooperate with raw material suppliers who have a good reputation, qualifications, and mature production processes to ensure that the purchased L-threonine raw materials meet relevant national standards and quality requirements. Indicators such as purity and impurity content should all reach the specified standards.
Conduct strict inspection and acceptance: Carry out strict inspections on each batch of L-threonine raw materials, including appearance, properties, content, heavy metal content, and microbial indicators. Adopt advanced detection technologies such as high-performance liquid chromatography to ensure the stability of the raw material quality and the absence of harmful impurities.
II. Formula Design and R&D
Follow standard specifications: According to relevant national laws, regulations, and standards, such as the "National Food Safety Standard for Infant Formula Foods" and the "National Food Safety Standard for Larger Infant and Young Child Formula Foods", reasonably determine the addition amount of L-threonine in infant formulas to ensure that it is within the safe range.
Consider nutritional balance: During formula design, comprehensively consider the nutritional needs of infants and young children and the interactions among various nutrients, so that L-threonine maintains an appropriate proportion with other amino acids, vitamins, minerals, and other nutrients, avoiding the impact on the health of infants and young children due to excessive or insufficient intake of a certain nutrient.
Carry out safety assessment: In the formula R&D stage, use various means such as animal experiments and in vitro cell experiments to conduct safety assessments on the formula after adding L-threonine, observe its effects on aspects such as growth and development, immune function, and metabolism, and ensure that there are no potential safety risks.
III. Production Process Management
Good Manufacturing Practice (GMP): Production enterprises should strictly comply with GMP requirements, establish a complete quality management system, ensure that the production environment is clean and hygienic, production equipment is regularly maintained and calibrated, and the production process is carried out strictly in accordance with operating procedures to prevent L-threonine from being contaminated or deteriorated during the production process.
Accurate measurement and mixing: Use high-precision measurement equipment to ensure that the addition amount of L-threonine and other raw materials is accurate. At the same time, optimize the mixing process to ensure that L-threonine is evenly distributed in the formula and prevent local concentrations from being too high or too low.
Hygiene control: Strengthen the hygiene management during the production process, conduct strict health checks and hygiene training for production personnel, and require them to comply with hygiene operating procedures. Regularly disinfect the production workshop, equipment, packaging materials, etc. to prevent microbial contamination.
IV. Product Testing and Monitoring
Finished product inspection: Conduct a comprehensive inspection of each batch of infant formula products, including the detection of L-threonine content, sensory indicators, physical and chemical indicators, and microbial indicators, to ensure that the products meet national standards and internal enterprise standards.
Stability test: Regularly conduct stability tests on products, observe the quality changes of products under different storage conditions (such as temperature, humidity, light, etc.), evaluate the stability of L-threonine in the products and the shelf life, and ensure the quality and safety of products during the shelf life.
Market monitoring and feedback: Establish a complete market monitoring system, collect consumer feedback and market sampling inspection information, promptly discover and deal with potential safety issues. For problem products that appear, quickly take measures such as recalls to protect the health and safety of consumers.
V. Labeling and Usage Instructions
Accurately label information: Accurately label information such as the content of L-threonine, usage method, and applicable population on the product label, so that consumers can clearly understand the composition and usage requirements of the product.
Warnings and precautions: Indicate special situations such as possible allergic reactions caused by L-threonine in the product, and remind parents to closely observe the physical reactions of infants and young children during use. If any discomfort symptoms occur, they should seek medical attention in a timely manner.
