烹饪过程中油脂氧化的控制与营养保留

摘 要

油脂在烹饪过程中的氧化反应是影响食品品质和营养价值的重要因素，其产生的有害物质可能对人类健康造成潜在威胁。本研究旨在探讨烹饪过程中油脂氧化的控制策略及其对营养成分保留的影响，以期为优化烹饪工艺提供科学依据。研究采用动态模拟烹饪环境的方法，通过控制温度、时间、氧气浓度及抗氧化剂添加量等关键参数，系统分析了不同条件下油脂氧化程度的变化规律及其对脂肪酸组成、维生素E含量和热敏性营养物质的影响。结果表明，高温和长时间加热显著加速了油脂的氧化进程，而降低氧气暴露水平或适量添加天然抗氧化剂可有效抑制氧化反应的发生。此外，研究发现一种新型复合抗氧化体系能够在不影响食品风味的前提下显著延缓油脂氧化，从而更好地保留其中的营养成分。本研究的创新点在于首次将动态模拟技术与抗氧化机制相结合，揭示了烹饪过程中油脂氧化的关键调控因素，并提出了切实可行的优化方案，为提升食品品质和保障消费者健康提供了重要参考。研究成果不仅丰富了烹饪科学的基础理论，还为实际应用中减少油脂氧化危害提供了技术支撑。

The oxidation of oils during the cooking process is a critical factor affecting food quality and nutritional value, and the harmful substances generated may pose potential health risks to humans. This study aims to investigate the control strategies for oil oxidation during cooking and their impact on the retention of nutritional components, providing scientific evidence for optimizing cooking techniques. A dynamic simulation of the cooking environment was employed, and key parameters such as temperature, time, oxygen concentration, and antioxidant dosage were controlled to systematically analyze the variation patterns of oil oxidation under different conditions and their effects on fatty acid composition, vitamin E content, and heat-sensitive nutrients. The results indicate that high temperatures and prolonged heating significantly accelerate the oxidation of oils, whereas reducing oxygen exposure or adding an appropriate amount of natural antioxidants can effectively suppress oxidative reactions. Additionally, a novel composite antioxidant system was found to significantly delay oil oxidation without affecting food flavor, thereby better preserving its nutritional components. The innovation of this study lies in the first-time combination of dynamic simulation technology with antioxidant mechanisms, revealing the key regulatory factors of oil oxidation during cooking and proposing feasible optimization solutions. This research not only enriches the fundamental theories of culinary science but also provides technical support for minimizing the hazards of oil oxidation in practical applications, contributing importantly to enhancing food quality and safeguarding consumer health.
