There is a need for sustainable food production and processing that reduces resource use and increases the availability of nutritious, innovative, and sustainable food. A coordinated, multisectoral approach across the food supply chain is essential to address global food and nutrition insecurity. The dairy industry produces abundant bioactive compound streams that can be examined for their valuable functionalities. Whey protein phospholipid concentrate (WPPC) is a byproduct of whey protein isolate production and a source of many bioactive compounds, including the milk fat globule membrane (MFGM). Milk fat globule membrane has unique functionalities, such as promoting brain development, modulating the immune system, improving the growth of desirable gut bacteria, and reducing inflammatory and metabolic diseases. We recently demonstrated that WPPC contained relatively higher levels of MFGM proteins, representing 23% of the total protein and phospholipids accounting for 20% of the total fatty acid pool. In this symposium review, we use WPPC as a case study to demonstrate dairy streams with the potential to be used as cutting-edge ingredients to develop next-generation dairy foods that are nourishing, innovative, and sustainable. Additionally, we assessed the economic costs and benefits of higher-valued uses of WPPC (e.g., in human food applications rather than as animal feed), which complements the discussion of the functionality of WPPC in various applications.
需要可持续的食品生产和加工方式，以减少资源使用，并增加营养丰富、创新且可持续的食品供应。跨食品供应链采取协调一致的多部门方法对于解决全球粮食和营养不安全问题至关重要。乳制品行业产生了大量生物活性化合物流，可对其有价值的功能进行研究。乳清蛋白磷脂浓缩物（WPPC）是乳清蛋白分离物生产的副产品，也是许多生物活性化合物的来源，包括乳脂肪球膜（MFGM）。乳脂肪球膜具有独特的功能，如促进大脑发育、调节免疫系统、促进有益肠道细菌的生长以及减少炎症和代谢性疾病。我们最近证明，WPPC中MFGM蛋白的含量相对较高，占总蛋白的23%，磷脂占总脂肪酸池的20%。在本次专题综述中，我们以WPPC为例，展示具有潜力用作前沿成分来开发营养丰富、创新且可持续的下一代乳制品的乳制品流。此外，我们评估了WPPC高价值用途（如用于人类食品而非动物饲料）的经济成本和效益，这补充了WPPC在各种应用中的功能讨论。
