摘 要
食品加工过程中微生物污染是影响食品安全的主要因素之一，其控制策略的优化对保障公众健康具有重要意义。本研究旨在探讨食品加工环节中微生物污染的关键来源及其传播机制，并提出针对性的控制措施以提升食品安全水平。通过结合实验室模拟实验与实际生产数据，采用分子生物学技术、风险评估模型及统计分析方法，系统分析了不同加工条件下微生物的存活特性及其对食品质量的影响。研究发现，特定加工参数（如温度、湿度和时间）对微生物活性具有显著调控作用，同时开发了一种基于实时监测的动态预警系统，可有效降低污染风险。该研究创新性地提出了“全过程微生物风险管理”理念，将传统单一控制点扩展为多维度防控体系，显著提高了食品加工过程的安全性和可控性。研究成果为食品行业制定更科学的微生物控制标准提供了理论依据和技术支持，对推动食品安全管理现代化具有重要参考价值。

Abstract
Microbial contamination during food processing is one of the primary factors affecting food safety, and the optimization of control strategies plays a crucial role in safeguarding public health. This study aims to investigate the critical sources of microbial contamination and their transmission mechanisms in food processing operations while proposing targeted measures to enhance food safety. By integrating laboratory simulation experiments with real-world production data, molecular biology techniques, risk assessment models, and statistical analysis methods were employed to systematically analyze the survival characteristics of microorganisms under various processing conditions and their impacts on food quality. The findings indicate that specific processing parameters, such as temperature, humidity, and time, significantly regulate microbial activity. Additionally, a dynamic early warning system based on real-time monitoring was developed, effectively reducing contamination risks. Innovatively, this research introduces the concept of "comprehensive microbial risk management," expanding traditional single control points into a multi-dimensional prevention and control system, thereby substantially improving the safety and controllability of food processing. The results provide theoretical foundations and technical support for the food industry to establish more scientific microbial control standards, offering significant reference value for advancing the modernization of food safety management.
