Algal Oil DHA Microencapsulated Powder 7%–20% (Whey Protein Base)
Algal Oil DHA Microencapsulated Powder 7%–20% (Whey Protein Base)
Omega-3 DHA Microencapsulated Powder 7% 10% 20%
DHA Microencapsulated Powder (Whey Protein Base) is a functional Omega-3 ingredient produced using advanced microencapsulation technology. High-quality DHA algal oil is encapsulated within a whey protein matrix, forming stable microcapsules that contain sub-micron and nano-scale oil droplets. This structure effectively protects DHA from oxidation while improving stability and handling during food processing.
The product is manufactured as a dry, free-flowing powder with no sticking, caking, or hygroscopicity. It demonstrates good water solubility, excellent stability, and strong flowability, making it easy to incorporate into powdered or solid nutritional formulations. The powder has a mild DHA aroma without any unpleasant odor.
DHA Microencapsulated Powder contains ≥7%, ≥10%, or ≥20% DHA in natural triglyceride (TG) form and is produced using DHA algal oil derived from Schizochytrium microalgae cultivated through patented closed-tank fermentation technology. The oil is extracted via physical separation and distillation processes, ensuring no solvent residues.
Compared with many marine oils, the algal DHA oil used in this ingredient offers high DHA content, low EPA levels, low peroxide value, and low anisidine value, ensuring excellent oxidative stability and consistent product quality.
This microencapsulated DHA powder is widely used in infant nutrition, dietary supplements, health foods, foods for special medical purposes (FSMP), and functional nutrition products, including infant formula milk powder, formulated milk powder, solid beverages, and tablets.
The product is produced under internationally recognized food safety systems, including ISO9001, ISO22000, and FSSC22000, and meets global certification requirements such as Halal and Kosher.
Description
DHA Microencapsulated Powder (Whey Protein Encapsulation)
1.High-Stability Microcapsule DHA Ingredient for Nutritional Applications
DHA (Docosahexaenoic Acid) is a long-chain polyunsaturated fatty acid belonging to the Omega-3 family. It is widely recognized as an essential nutrient for human health and development and is commonly referred to as “brain gold”.
DHA plays a critical role in the structure and function of the nervous system. It is an important structural component of both the brain and the retina. In the human cerebral cortex, DHA accounts for approximately 20% of fatty acids, while in the retina it represents about 50% of total fatty acids.
Because the human body has very limited capacity to synthesize DHA, adequate intake must be obtained from dietary sources or nutritional supplementation. For this reason, DHA has become an essential ingredient in many nutritional products, particularly those intended for infants, children, and maternal nutrition.
2.Microencapsulation Technology
DHA is highly unsaturated and sensitive to oxidation, light, and environmental conditions. To improve its stability and allow its use in various food formulations, the DHA algal oil is processed using microencapsulation technology.
Through this process, DHA oil is emulsified and encapsulated inside a protective whey protein carrier system. The encapsulation process creates sub-micron and nano-scale oil droplets that are uniformly distributed inside the microcapsule matrix.
This microcapsule structure offers several advantages:
• Protection of DHA from oxidation
• Improved product stability during storage
• Enhanced compatibility with food processing conditions
• Uniform dispersion in nutritional formulations
The resulting powder has the following characteristics:
• Dry powder appearance
• No sticking or caking
• Non-hygroscopic properties
• Good solubility in water
• Excellent flowability during processing
The powder also exhibits a light DHA oil aroma without unpleasant odors, making it suitable for sensitive nutritional formulations.
3.High-Quality DHA Algal Oil
The DHA used in this microencapsulated powder is derived from marine microalgae (Schizochytrium) cultivated through patented fermentation technology in closed fermentation tanks.
The production process includes controlled microbial fermentation followed by physical separation and distillation technologies to obtain purified DHA algal oil. The process does not involve solvent extraction, ensuring a clean and safe ingredient.
The resulting algal DHA oil has the following characteristics:
• High DHA concentration
• Low EPA content
• Low peroxide value
• Low anisidine value
• No solvent residue contamination
These properties contribute to improved stability, reduced fishy odor, and longer shelf life for the finished product.
4.Natural Triglyceride (TG) Form DHA
The DHA contained in this ingredient exists in natural triglyceride (TG) form, which is the natural structure of DHA found in foods.
Triglyceride-form DHA is widely used in nutritional ingredients because of its compatibility with food formulations and its efficient absorption in the human body.
5.Encapsulation Formulation Options
To meet different product development needs, DHA microencapsulated powder can be provided with different carrier systems.
