In the ever-growing world of food production and innovation, natural and sustainable solutions play an increasingly important role. Algae extracts for food not only offer a wide range of applications, but also open up new horizons for healthier and more environmentally friendly food.
Why are algae an interesting source of extracts?
Algae are an extremely interesting source of extracts for several reasons. They are known as a superfood and are valued for their high nutrient density. Algae are rich in essential nutrients such as vitamins, minerals and proteins, which makes them a valuable addition to the human diet.
In addition, algae contain ingredients that are difficult to find in other foods or are only present in small amounts. These include, for example, Astaxanthin powder, which is extracted from the microalgae Haematococcus pluvialis, and omega-3 fatty acids in algae oil, which are found in particular in certain microalgae.
In addition, algae offer a vegan and vegetarian alternative to animal products. For example, algae can serve as a source of plant-based protein and is an option for those who avoid animal products for ethical, health or environmental reasons.
The versatility of algae in the food industry ranges from flavor enhancements to enriching products with nutrients to use as functional ingredients. Algae extracts for food offer a more concentrated and targeted way to use these active ingredients in foods.
What can algae extracts for food do?
Algae extracts for food can produce a variety of effects and changes. They can basically be divided into two categories.
In the functional ingredient category, algae extracts are used to adjust the texture, taste and color of foods. They can serve as thickeners or gelling agents to affect the consistency of products. In addition, they are capable of improving the flavor of foods by inducing umami-like or salty flavors. Some types of algae contain natural pigments that can be used as food colorants.
The other main category is to use algae extracts to optimize the nutritional profile of foods. Algae are rich in various nutrients, including proteins, omega-3 fatty acids, vitamins and minerals. Food manufacturers can use algae extracts to fortify their products with these healthy ingredients to improve the nutritional profile. This application enables the production of healthier foods and provides alternatives to reduce unhealthy ingredients in products.
Which algae extracts can perform functional tasks in formulations?
Some algae extracts for food, such as Agar, Alginate and Carrageenan, serve as thickeners and gelling agents. They allow modification of the texture and consistency of foods and are often used in products such as jellies, puddings, pie fillings and ice cream. This can give foods a pleasant, or more beneficial texture for production, as well as provide a vegan gelatin substitute.
Certain algae extracts serve as natural food colorants. For example, Phycocyanin, extracted from the cyanobacterium Spirulina platensis (nevertheless colloquially referred to as microalgae), produces a striking blue color. Astaxanthin, obtained from the microalgae Haematococcus pluvialis, and Dunaliella salina powder can give foods a red to orange pigment. These products are particularly interesting for food colors that can be used in confectionery, for example.
Some food algae, such as Spirulina platensis, have flavor-enhancing properties. Although Spirulina is not suitable for all applications due to its earthy, slightly fishy taste, it can be used in certain recipes to intensify the flavor of fish dishes or other foods. Another example of flavor optimization using algae extracts is Laminaria sp. which can be used to create an umami flavor.
Which algae extracts can be incorporated into formulations to optimize the nutritional profile?
Algae and their derived extracts can be incorporated into food formulations to optimize the nutritional profile. Although not directly an algae extract, seawater extract is rich in important minerals such as magnesium. The use of seawater extract in food products can help to increase the levels of minerals and trace elements, which is particularly interesting for products seeking higher mineral coverage.
An interesting source of omega-3 fatty acids such as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are the microalgae Schizochytrium sp. and Nannochloropsis sp. These omega-3 fatty acids are important for brain and heart health. Algae extracts for foods rich in DHA and EPA can be used as an ingredient in foods such as dietary supplements, fortified juices and beverages, and plant-based milk alternatives to increase levels of these essential fatty acids.
Incorporating algae extracts and related ingredients into food formulations provides an opportunity to fortify nutrients and improve the nutritional profile of foods. This is particularly relevant for manufacturers looking to offer products with additional health benefits and to meet growing consumer demand for nutrient-rich foods.
What form do algae extracts for food come in?
Algae extracts for food are available in a variety of forms to meet different food manufacturing needs. They can be in the form of powder or in liquid form, such as algae oil or oleoresin.
Powdered algae extracts are widely used for food fortification and are easily incorporated into dry mixes for baked goods, smoothies, soups, sauces and pasta products. Algal oil, such as Schizochytrium sp. Algal oil, which is rich in omega-3 fatty acids, can be used in fortified foods and supplements under certain conditions. Oleoresins, such as Astaxanthin oleoresin, concentrated liquid extracts find use in various foods to enhance flavor and color.
The choice of form depends on the specific requirements of food production, including the desired application and the type of food product. Powder is often versatile and easy to handle, while liquid forms are used in specialized applications.
Which algae extracts for food can contribute to vegetarian/ vegan diets?
Algae extracts for food can make a valuable contribution to vegetarian and vegan diets by providing an alternative to animal products.
Schizochytrium sp. is a microalgae rich in DHA (docosahexaenoic acid). Schizochytrium algae extracts provide a vegan source of DHA and are particularly relevant to vegetarian and vegan diets as they can help reduce the need for animal products. Like Schizochytrium, Nannochloropsis sp. is a microalgae rich in EPA (eicosapentaenoic acid), another important omega-3 fatty acid. Nannochloropsis algae extracts offer a plant-based, vegan alternative to ensure a supply of EPA.
Chlorella vulgaris and Spirulina platensis are other microalgae that can serve as vegan protein sources. They are rich in protein and contain essential amino acids. Algae extracts from Chlorella and Spirulina can be used in a variety of vegan and vegetarian foods to increase protein content.
What benefits do algae extracts offer to food producers?
Algae extracts offer a wide range of benefits to food producers. They serve as a versatile “tool” for shaping products in terms of color, flavor, texture and nutritional profile. The natural ingredients from algae can help improve the sensory and nutritional profile of foods, which can increase consumer satisfaction.
In addition, algae extracts are a sustainable and natural raw material. Algae grow quickly, have a smaller environmental footprint, and are therefore more environmentally friendly than many other resources. This helps to meet the sustainability goals of food manufacturers and reduce the environmental impact of production.
The use of algae extracts in the food industry also shows innovation potential and a forward-looking commitment. It enables the development of new products that meet the changing needs of consumers and fits well with trends such as clean label and sustainable nutrition. At a time when environmental concerns and health awareness are becoming increasingly important, algae extracts for food are a promising element in the food industry.
In a world with an ever-growing population and limited land resources, algae extracts are becoming increasingly important as a sustainable solution. Algae grow more efficiently and require less land area compared to conventional crops. This characteristic makes algae a resource-efficient option to meet the increasing demand for food.
