Oleogels developed through the direct-dispersion method offer an innovative, scalable, and efficient alternative to traditional fats in sausage production, providing a solution to health concerns associated with the high saturated fat content of conventional formulations. By closely mimicking the texture, stability, and mouthfeel of animal fats, these oleogels provide a novel approach to improving the nutritional profile of sausages while maintaining desirable sensory characteristics. This review critically evaluates cutting-edge research on oleogels, emphasizing innovations in their ability to enhance emulsion stability, increase cooking yield, reduce processing weight loss, and optimize fatty acid composition by reducing overall fat and saturated fat levels. Despite their potential, sausage formulations with oleogel still face challenges in achieving consistent sensory properties, texture, and oxidative stability, often failing to fully replicate the sensory qualities and shelf-life of animal fats. To push the boundaries of oleogel technology and meet the increasing demand for healthier, high-quality sausage products, we propose focused innovations in refining oil-to-gelator ratios, exploring a wider range of novel gelators, optimizing production methods, and developing cost-effective, scalable strategies. These advancements hold significant potential for revolutionizing the sausage industry by improving both the technological and nutritional qualities of oleogels.
通过直接分散法制备的油凝胶为香肠生产中的传统脂肪提供了一种创新、可扩展且高效的替代品,解决了与传统配方中高饱和脂肪含量相关的健康问题。通过紧密模拟动物脂肪的质地、稳定性和口感,这些油凝胶提供了一种新颖的方法来改善香肠的营养成分,同时保持理想的感官特性。本文综述批判性地评估了油凝胶的前沿研究,强调了它们在增强乳液稳定性、提高烹饪产量、减少加工重量损失以及通过降低总脂肪和饱和脂肪水平来优化脂肪酸组成方面的创新能力。尽管具有潜力,但含有油凝胶的香肠配方在实现一致的感官特性、质地和氧化稳定性方面仍面临挑战,往往无法完全复制动物脂肪的感官品质和保质期。为了突破油凝胶技术的界限并满足对更健康、高品质香肠产品日益增长的需求,我们建议在优化油与凝胶剂比例、探索更广泛的新型凝胶剂、优化生产方法以及制定具有成本效益的可扩展策略方面进行有针对性的创新。这些进展对于通过改善油凝胶的技术和营养品质来彻底改变香肠行业具有巨大潜力。
