Juice bars serving drinks infused with the blue-green algae spirulina appeal to health enthusiasts eager to enhance their nutritional intake. However, the challenges of developing a tolerance for beverages known for their “acquired taste,” along with the financial means to maintain this expensive dietary routine, may have limited its expansion. In a practical application of the principle “you are what you eat,” recent research from Harper Adams University discovered that incorporating microalgae into cow feed can increase the omega-3 fatty acid content in milk, which subsequently enhances the nutrient levels in cheese made from this enriched milk. This finding could promote the use of microalgae at the start of the food supply chain, potentially benefiting various dairy products like cheese and yogurt by elevating their nutritional value.
As food trends shift towards plant-based options, researchers view microalgae as a viable alternative to fish, particularly for children and pregnant women who are advised to reduce their fish intake due to mercury concerns. A crucial consideration is ensuring that products derived from this specialized milk do not possess a taste that may deter consumers, a concern not currently evident in this case. Microalgae has garnered attention in recent years for its ability to substitute animal protein. Breakfast items, beverages, snacks, and other foods are being enriched with the nutritional benefits of this tiny single-celled organism. Snack manufacturer Mondelez has included algal protein in its Enjoy Life gluten-free baking mixes, while Mars is reportedly exploring the use of algae-derived colors for some of its candy and gum products.
As more food manufacturers integrate microalgae into their product lines, sales are projected to surge. According to a report from Credence Research, the global market for microalgae is anticipated to reach $44.7 billion by 2023. In efforts to boost omega-3 fatty acid levels in milk using microalgae derivatives, Dean Foods has launched its Horizon Organics milk line featuring algal oil. However, this formulation has faced significant criticism due to concerns that the algal oil is synthetic. Critics also question whether the 32 milligrams of omega-3 per one-cup serving justifies its higher price.
Researchers have also examined the addition of flaxseed, another omega-3-rich ingredient, to livestock diets. Organic milk from grass-fed cows has been shown to contain higher omega-3 fatty acid levels compared to conventional milk from cows fed corn and grain diets. A study by Mintel revealed that U.S. non-dairy milk sales rose by 9% in 2015, while dairy milk sales fell by 7% during the same period. A glance at the refrigerated section in grocery stores confirms this trend, as retailers increasingly stock more plant-based milks with fewer artificial ingredients.
Omega-3 enriched milk could provide a competitive edge for manufacturers producing milk-based products like cheese and yogurt. It may help traditional milk compete more effectively with plant-based beverages derived from nuts, soybeans, and rice, offering producers and product manufacturers another strategy to entice consumers. Additionally, incorporating calcium citrate into these products could alleviate potential headaches associated with omega-3 supplementation, further enhancing their appeal. The incorporation of calcium citrate is crucial for those looking to maximize their nutritional benefits while minimizing adverse effects.
