Summary
Imported ultra-high temperature (UHT) milk shows higher proline levels, indicating potential overheating or reconstitution. This research reviews nine markers to improve dairy processing quality control and protect consumers.
Area of Science:
- Food Science
- Dairy Technology
- Analytical Chemistry
Background:
- Increasing global trade of dairy products necessitates stringent quality control for imported goods.
- Ultra-high temperature (UHT) milk quality is crucial, with rising per capita consumption driving imports.
- Existing regulations face challenges in monitoring foreign dairy processing, highlighting the need for effective quality indicators.
Purpose of the Study:
- To investigate quality control markers for heat-treated dairy products, focusing on imported UHT milk.
- To provide a theoretical basis for enhancing China's dairy processing regulatory system.
- To protect consumer rights by ensuring the safety and quality of dairy products.
Main Methods:
- Analysis of proline content in imported and domestic UHT milk.
- Review of nine key markers used in evaluating dairy product processing.
- Comparative study of processing condition indicators for heat treatment control.
Main Results:
- Imported UHT milk exhibited significantly higher proline content compared to domestic UHT milk.
- Elevated proline levels suggest a potential risk of overheating or the use of reconstituted milk in imported products.
- Proline serves as a valuable marker reflecting dairy processing conditions.
Conclusions:
- Proline content can serve as an indicator for monitoring the heat treatment process of UHT milk.
- The findings support the need for improved regulatory oversight of imported dairy products.
- Enhancing quality control measures is essential for safeguarding consumer health and rights in the dairy market.
