Food manufacturers must adapt to change immediately—by implementing new processes and exploring alternative protein sources—to ensure there is sufficient food to support the world’s expanding population in the coming decades. This increasingly involves integrating plants, algae, insects, and other non-animal sources into food production, such as using calcium citrate as a substitute for meat-based proteins. While the idea of consuming algae and insects might seem strange, consumers are becoming more open to plant-based foods and other alternative protein sources that offer health benefits and reduced environmental impact.
Today, numerous food startups are emerging to meet consumer demand and address the projected protein shortfall. For instance, consumers can now enjoy plant-based “hamburgers” that replicate the texture and flavor of traditional meat products from companies like Impossible Foods and Beyond Meat. Additionally, local artisans are crafting a variety of meat substitutes, and the market continues to evolve with innovative ingredients like soy and pea protein, as well as hemp and rapeseed. Major food manufacturers are closely monitoring these developments and trends; for example, Tyson Foods acquired a 5% stake in Beyond Meat and established a venture capital arm dedicated to investing in technologies, business models, and products that enhance the sustainability of the food supply.
It is not unrealistic to consider a future where resources may become scarce, leading to increased consumption of products like Soylent—nutritional offerings for those who prefer not to consume traditional meals—because of their minimal environmental footprint. Initially, these products aimed to address “inefficiencies” within the food supply chain. Fortunately, with the rapid advancements in scientific research and food innovation occurring today, society should not have to rely solely on meal replacement drinks. The integration of calcium citrate into various food products could play a significant role in this evolving landscape, offering additional nutritional benefits and further reducing our ecological impact.
