摘要:

【目的】探究高水分、低盐条件下藏香猪肉腊肠的品质形成规律,阐明水分迁移与产品质地之间的关系,为突破传统腊肠产品普遍存在的高盐、干硬等技术瓶颈,开发兼具健康属性与优良品质的新型肉制品提供理论依据。【方法】采用双因素交互试验设计,分别在固定食盐添加量(1.5%)条件下调节水分含量(25%—50%),以及在固定水分含量(45%)条件下调节食盐添加量(1.0%—2.5%),制备藏香猪肉腊肠样品。系统测定其pH、色泽、质构、蒸煮损失、水分分布(低场核磁共振及成像)、风味(电子鼻和电子舌)及微观结构(扫描电镜),并结合感官评价,综合解析其品质演变规律。【结果】在固定食盐添加量(1.5%)条件下,随着水分含量的增加,腊肠的pH呈先降后升趋势、蒸煮损失率显著升高、不易流动水与自由水(T2)弛豫时间延长、质构硬度下降达49.61%;在固定水分含量(45%)条件下,随着食盐添加量的降低,pH无显著变化、蒸煮损失率上升,T2弛豫时间显著增加,氢质子密度先增后减,肌纤维结构由初期出现裂缝逐步优化为均匀致密后进一步变为粗糙杂乱。不同处理组间气味轮廓差异明显(P<0.05),而对滋味无显著影响。综合分析表明,水分含量45%、食盐添加量1.5%的藏香猪肉腊肠在色泽明亮度、质构适宜性、保水性能及微观结构均匀致密性等方面均表现最优。【结论】与传统低水分、高盐配方相比,高水分(45%)、低盐(1.5%)协同作用可优化藏香猪肉腊肠的蛋白质网络结构与水分分布状态,在显著降低食盐用量的同时,维持产品适宜的质构特性、良好的持水稳定性、协调的风味轮廓以及较高的感官接受度。

Abstract:

【Objective】This study was conducted to investigate the quality formation mechanism of Tibetan pork sausage under high-moisture and low-salt conditions and to clarify the relationship between moisture migration and product quality. It aimed to provide a theoretical basis for overcoming common technical bottlenecks in traditional sausage products, such as high salt content and excessive hardness, and for developing novel meat products with both health attributes and superior quality. 【Method】A two-factor interaction experimental design was adopted. Sausage samples were prepared under the following conditions: a fixed salt addition level of 1.5% and a moisture content adjusted in the range of 25% to 50%, and a fixed moisture content of 45% and a salt addition level adjusted in the range of 1.0% to 2.5%. The sausages were systematically analyzed for pH, color, texture, cooking loss, moisture distribution (via low-field nuclear magnetic resonance and imaging), flavor (using an electronic nose and an electronic tongue), and microstructure (via scanning electron microscopy). Sensory evaluation was also performed, and the data were analyzed to comprehensively elucidate the patterns of quality evolution. 【Result】Under the fixed salt addition level of 1.5%, the increase in moisture content led to an initial decrease followed by an increase in pH, a significant increase in cooking loss rate, a prolongation in T2 relaxation time (immobile and free water), and a reduction in texture hardness of up to 49.61%. With the moisture content fixed at 45%, with the decreasing of salt addition, several changes happened. Specifically, no significant change was observed in pH. The cooking loss rate rose, and the T2 relaxation time increased significantly. Whereas the hydrogen proton density exhibited an initial increase followed by a decrease, the muscle fiber structure underwent a progressive transformation: from initial cracking, to an optimized uniform and dense state, and finally to a rough and disordered morphology. The flavor profile showed significant differences between various treatment groups (P<0.05), whereas no significant differences were found in the taste profile. Comprehensive analysis indicated that the Tibetan pork sausages with a moisture content of 45% and a salt addition level of 1.5% demonstrated optimal performance in terms of color brightness, texture suitability, water retention capacity, and the uniformity and denseness of the microstructure. 【Conclusion】In contrast to traditional low-moisture and high-salt formulations, the high-moisture (45%) and low-salt (1.5%) formulation synergistically optimized both the protein network structure and moisture distribution state in Tibetan pork sausage. This approach significantly reduced salt consumption while maintaining suitable texture characteristics, good water-holding stability, a balanced flavor profile, and high sensory acceptability.
