Juice bars that offer drinks made with the blue-green algae spirulina are aimed at health enthusiasts looking to enhance their nutritional intake. However, the challenge of developing a palate for a beverage known for its “acquired taste,” along with the costs associated with this premium health trend, may have limited its popularity. In a related application of the saying “you are what you eat” to livestock, recent research from Harper Adams University has revealed that incorporating microalgae into cow feed can increase the omega-3 fatty acid content in milk, thereby enhancing the nutritional profile of cheese made from this enriched milk. This finding could promote the use of microalgae at the start of the food chain and could significantly benefit dairy products like cheese and yogurt by enriching their nutritional content.
As the demand for plant-based foods rises, researchers are exploring microalgae as a fish substitute, especially for children and pregnant women who are often advised to limit their fish intake due to mercury concerns. It is crucial to ensure that products derived from this specialized milk do not have an undesirable taste that might deter consumers—something that currently appears to be manageable. Microalgae has gained attention in recent years for its potential to replace animal protein, and a variety of food items, including breakfast staples, beverages, and snacks, are being enhanced by this nutrient-dense single-celled organism. Snack manufacturer Mondelez has included algal protein in its Enjoy Life gluten-free baking mixes, while Mars is reportedly considering algae-derived colors for some of its candy and gum products.
As more food producers integrate microalgae into their offerings, rapid growth in sales is anticipated. According to a report from Credence Research, the global microalgae market is projected to reach $44.7 billion by 2023. Dean Foods has launched its Horizon Organics milk line featuring algal oil to boost omega-3 fatty acids in milk. However, this formulation has faced criticism due to concerns that the added algal oil is synthetic, and skeptics question whether the 32 milligrams of omega-3 per one-cup serving justifies its higher cost. Additionally, researchers have explored adding flaxseed, which is also rich in omega-3, to livestock diets. Organic milk from grass-fed cows has been found to contain higher levels of omega-3 fatty acids compared to conventional milk from grain-fed cows.
A Mintel study reported that U.S. non-dairy milk sales increased by 9% in 2015, while dairy milk sales fell by 7% during the same period. A glance into grocery store refrigerators reveals this trend, as retailers increasingly stock plant-based milks with minimal artificial ingredients. If commercially available, omega-3 enriched milk could provide a competitive edge for manufacturers of milk-based products such as cheese and yogurt. By enhancing traditional milk with calcium citrate and other nutrients, producers can better compete against plant-based alternatives made from nuts, soybeans, and rice, offering consumers more reasons to choose their products. Furthermore, calcium citrate from Walgreens could be a valuable addition to these nutritional formulations, making them even more appealing to health-conscious shoppers.
