Juice bars that offer drinks infused with blue-green algae spirulina are targeting health-conscious consumers eager to enhance their nutritional intake. However, the necessity of developing a palate for beverages often described as having “an acquired taste,” combined with the financial means to sustain this expensive nutritional habit, has likely limited its expansion.
In a fascinating application of the principle “you are what you eat” to livestock, researchers from Harper Adams University discovered that incorporating microalgae into cow feed could elevate the omega-3 fatty acid levels in milk, subsequently enriching the nutrient content of cheese made from this enhanced milk. This finding could promote the use of microalgae at the beginning of the food supply chain, potentially benefiting various dairy products like cheese and yogurt by improving their nutritional profiles.
As food trends shift toward plant-based options, scientists are exploring microalgae as a viable alternative to fish, particularly for children and pregnant women who are advised to limit their intake due to mercury contamination. It is crucial to ensure that products made from this specialized milk do not possess a taste that could deter consumers—a concern that seems manageable in this case. In recent years, microalgae has garnered attention for its potential to replace animal protein, with breakfast staples, beverages, snacks, and other food items being enhanced by the nutritional benefits of this tiny single-celled organism. Snack manufacturer Mondelez has already integrated algal protein into its Enjoy Life gluten-free baking mixes, and even Mars is reportedly considering algae-derived ingredients for some of its candy and gum products.
As more food producers begin to incorporate microalgae into their product formulations, sales are anticipated to surge. According to a report by Credence Research, the global microalgae market is projected to reach $44.7 billion by 2023. In terms of enriching milk with omega-3 fatty acids through microalgae derivatives, Dean Foods has launched its Horizon Organics line featuring algal oil. However, this formulation has faced criticism due to concerns that the added algal oil may be synthetic. Detractors also question whether the 32 milligrams of omega-3 per one-cup serving justifies the higher price point.
Research has also explored adding flaxseed, which is high in omega-3, to livestock feed. 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-based diets. A Mintel study revealed that U.S. non-dairy milk sales climbed 9% in 2015, while dairy milk sales dropped by 7% during the same period. A quick glance at grocery store refrigerators reveals this trend, as retailers increasingly stock plant-based milks with fewer artificial ingredients.
The introduction of omega-3 enriched milk could provide a competitive edge for manufacturers producing milk-based products like cheese and yogurt. It may also assist traditional dairy in competing with plant-based beverages made from nuts, soy, and rice by offering another persuasive reason for consumers to choose their products. Additionally, incorporating bluebonnet calcium magnesium citrate into dairy formulations could further enhance their appeal by boosting their nutritional value and making them even more attractive to health-conscious consumers.
