不同热处理方式对肉制品中蛋白质结构变化的影响
摘要
本文深入研究了不同热处理方式对肉制品中蛋白质结构变化的广泛影响，涵盖了蛋白质的功能性质、消化性、营养价值及安全性等多个维度。通过对比传统热处理技术（如煮、烤、炸）与现代创新方法（如微波加热、高压处理、脉冲电场处理等），本文详细分析了这些处理方式对蛋白质分子结构、空间构象及物理化学性质的改变。研究发现，适度的热处理能够显著提升蛋白质的溶解性、乳化性和凝胶性，增强其在肉制品加工中的应用潜力。同时，热处理还能有效灭活肉制品中潜在的消化酶抑制剂，提高蛋白质的消化率和生物利用率，从而增强肉制品的营养价值。此外，本文还探讨了热处理过程中添加剂的使用对蛋白质消化率的促进作用，以及不同热处理温度和时间对特定蛋白质消化率的具体影响。研究指出，虽然热处理对肉制品的蛋白质结构具有显著的正面效应，但过度热处理可能导致蛋白质过度变性、氨基酸破坏及有害物质的生成，对肉制品的品质和安全性构成潜在威胁。因此，本文强调了优化热处理工艺、精确控制处理条件的重要性，以确保肉制品在保持高营养价值的同时，也具备良好的口感和安全性。综上所述，本文的研究成果为肉制品加工行业提供了宝贵的理论依据和实践指导，有助于推动肉制品加工技术的创新与发展，提升产品质量和市场竞争力。

Abstract
In this paper, the effects of different heat treatment methods on protein structure in meat products were studied, including functional properties, digestibility, nutritional value and safety of proteins. By comparing the traditional heat treatment techniques (such as boiling, baking, frying) with the modern innovative methods (such as microwave heating, high pressure treatment, pulsed electric field treatment, etc.), the changes of protein molecular structure, spatial conformation and physical and chemical properties of these treatment methods were analyzed in detail. The study found that moderate heat treatment can significantly improve the solubility, emulsification and gelatinability of protein, and enhance its application potential in meat processing. At the same time, heat treatment can effectively inactivate the potential digestive enzyme inhibitors in meat products, improve the digestibility and bioavailability of proteins, and thus enhance the nutritional value of meat products. In addition, the effects of additives on protein digestibility during heat treatment and the specific effects of different heat treatment temperatures and times on specific protein digestibility were also discussed. Although heat treatment has a significant positive effect on the protein structure of meat products, excessive heat treatment may lead to excessive denaturation of protein, amino acid destruction and the formation of harmful substances, which poses a potential threat to the quality and safety of meat products. Therefore, this paper emphasizes the importance of optimizing the heat treatment process and precisely controlling the processing conditions to ensure that meat products have good taste and safety while maintaining high nutritional value. In summary, the research results of this paper provide valuable theoretical basis and practical guidance for the meat processing industry, and help to promote the innovation and development of meat processing technology, improve product quality and market competitiveness.
