Application of algae oil DHA in dairy products

As consumers' demand for healthy food increases, dairy products, as an important source of nutrition, are receiving increasing attention in the development and application of functional ingredients. DHA (docosahexaenoic acid) is a polyunsaturated fatty acid that is vital to human health. Its application in dairy products is of particular concern.

(1) Source of algae oil DHA

DHA is mainly found in deep-sea fish oil and microalgae oil. Compared with deep-sea fish oil, microalgae oil DHA has the advantages of stable source, no heavy metal pollution, and no EPA (eicosapentaenoic acid), making it an important source of DHA. At present, microalgae oil DHA is mainly obtained by cultivating DHA-rich microalgae and extracting it.

(2) Physiological functions of algal oil DHA

DHA has various physiological functions in the human body. First of all, DHA is an important component of the brain and retina and is crucial to the brain and vision development of infants and young children. Secondly, DHA has anti-inflammatory, antioxidant, and lower risk of cardiovascular disease effects. In addition, DHA also has positive effects on immune regulation, neuroprotection, and other aspects.

(3) Safety of algae oil DHA

Algae oil DHA has undergone strict production technology and quality control and has high safety. Multiple studies have shown that algae oil DHA has no obvious toxic or side effects on the human body and is easily absorbed and utilized by the human body. Therefore, the application of algal oil DHA in dairy products has good safety and feasibility.

(1) Infant formula milk powder

Infant formula milk powder is one of the main directions for the application of algal oil DHA in the dairy field. Adding algae oil DHA to infant formula milk powder can effectively promote the brain and vision development of infants and children and improve their intelligence. At present, many well-known dairy companies at home and abroad have added algae oil DHA to infant formula milk powder to meet consumer demand for high-quality infant milk powder.

(2) Dairy products for adults

In addition to infant formula, algal oil DHA is also gradually used in adult dairy products. For example, adding algae oil DHA to dairy products such as yogurt and cheese can enrich the nutritional value of dairy products and improve consumers' health. In addition, some functional dairy products such as sports drinks and nutritious breakfast milk have also begun to try to add algae oil DHA to meet the needs of specific groups of people.

(3) Liquid dairy products

Liquid dairy products such as milk, soy milk, etc. are also potential areas for the application of algal oil DHA. By adding algae oil DHA, the nutritional content of liquid dairy products can be enriched and their nutritional value improved. At the same time, the portability and digestibility of liquid dairy products also make the addition of algal oil DHA more convenient and efficient.

(1) Diversification of functional dairy products

As consumer demand for healthy foods continues to increase, the market for functional dairy products will continue to expand. As an important functional ingredient, algae oil DHA will be used in more types of dairy products to meet the diverse needs of consumers.

(2) Optimization of production process

To improve the stability and bioavailability of algal oil DHA in dairy products, the production process and formula design need to be further optimized. For example, microencapsulation technology is used to encapsulate algal oil DHA in tiny particles, which can improve its stability and dispersion in dairy products. At the same time, the bioavailability of algal oil DHA can be further optimized by adjusting factors such as the pH value and ionic strength of dairy products.

(3) Satisfaction of personalized nutritional needs

Given the differences in nutritional needs of different groups of people, the dairy market will pay more attention to meeting personalized nutritional needs. As an important nutrient, algae oil DHA can be customized and added according to the needs of different groups of people to meet their personalized nutritional needs. For example, adding an appropriate amount of algae oil DHA to infant formula can meet the needs of infants and young children for brain and vision development; adding algae oil DHA to dairy products for the elderly can prevent the occurrence of cardiovascular diseases and other elderly diseases.

As an important functional ingredient, algal oil DHA has broad prospects and potential for application in the dairy field. By optimizing the production process and formula design, and meeting individual nutritional needs, the application and development of algal oil DHA in the dairy field can be further promoted.

HSF's R&D team has been deeply engaged in production strain selection strategies and high-yield strain selection and optimization technologies during ten years of development and cooperation and has accumulated experience in fermentation technology and production experience. With the help of modern biotechnology, information technology, and engineering equipment, the team achieved multi-link optimization and reconstruction of fermentation research methods and fermentation processes and gradually solved the problem of industrialization of DHA algae oil.

Microencapsulation technology is a technology that encapsulates solid, liquid, or gas substances in tiny capsules. In the production of algal oil DHA, microencapsulation technology is mainly used to improve the stability and bioavailability of DHA. HSF has patented microcapsule technology. By selecting appropriate wall materials and embedding conditions, DHA algae oil is encapsulated in tiny capsules to form a protective microcapsule product.

HSF-encapsulated algal oil DHA has the following significant advantages:

Improve stability: Through microencapsulation technology, DHA can be effectively protected from the influence of the external environment, thereby significantly improving the stability of the product.

Extended shelf life: Microencapsulation can slow down the oxidation rate of DHA, extend the shelf life of the product, and provide consumers with a longer fresh experience.

Improve bioavailability: Microencapsulation technology can improve the dissolution and dispersion properties of DHA in the body and increase its absorption and utilization in the human body.

As a professional manufacturer that understands its customers better, HSF extends the application scope of DHA algae oil as much as possible and creates a full range of product platforms for customers. With the support of encapsulation technology, DHA algae oil powder, which is easier to apply, was also launched. It perfectly solves the application problems existing in DHA algae oil such as poor bioavailability, poor water solubility, easy oxidation, poor taste, difficulty in premixing, and difficulty in transportation.
