Algae DHA oil is fermented from marine microalgae. At present, there are three types of microalgae approved by the National Health Commission of China to produce DHA, namely, Schizochytrium, Okenytrium, and Crypthecodinium. Among them, Schizochytrium has passed the US FDA GRAS consensus assessment and can be used in infant formula.
DHA from algae oil has a pure taste, no fishy smell, and almost no EPA. It has the characteristics of quality safety, quality control, traceability, and recyclability. It is very suitable for infants, pregnant women, and other groups. Algae oil DHA has been widely used in food, health products, and medicine in recent years.

Advantages of HSF's FermAlge® DHA oil
HSF's experience in fermentation has been over 10 years.
FermAlge®, an HSF brand for fermented materials, was launched in 2022.
Advantages of strains
Since the establishment of the molecule laboratory in 2012, HSF has been committed to strain screening and bio-fermentation technology. From 218 original strains, HSF successfully isolated the high-DHA-producing Schizochytrium HSc-01.
The Schizochytrium selected by HSF from the laboratory has stable batch growth, uniform and full bacterial color, and a total DHA content of up to 70%.
Advantages of fermentation technology
While screening strains, the HSF team also continues to accumulate fermentation technology and production experience in experiments.
During production, the algae species need to be placed in a culture medium containing carbohydrates, proteins, and a variety of trace elements for fermentation and cultivation and gradually transferred to primary, secondary, and tertiary fermentation tanks for cultivation. During the cultivation process, in addition to the need to input culture medium and control various environmental factors such as temperature, humidity, oxygen, and light, the entire operation needs to be carried out in a fully closed and sterile environment. Each process uses the most advanced equipment currently available, and no chemical solvents are added throughout the process, and there is no risk of chemical pollution residues. It is a biosynthetic, environmentally friendly, and sustainable DHA.
Advantages of product
As a professional functional lipid producer in China, HSF has a solid foundation in the production of functional lipids, from natural vitamin E and plant sterol extraction, and separation to esterification. While extracting DHA contained in Schizochytrium, HSF protects the functional structure of DHA algae oil to the maximum extent, minimizes the impact of aldehydes and ketones in DHA algae oil on flavor, and minimizes the residues in the product and the chemical reactions produced. The functional oil refining technology has a profound foundation, the oil is clear, and the product is pure.
High-purity algae oil, stable batch content, DHA content far exceeds European and American standards, and the content of EPA, an "unfriendly ingredient" for infants and young children, is extremely low.
Advantages of the production line
Since 2022, HSF has invested RMB 110 million to build a fermentation production line that can perfectly demonstrate HSF's R&D technology accumulation. This fermentation production line brings together more than ten years of wisdom from HSF. It is a thousand-ton production line that is very suitable for the industrialization of DHA algae oil at this stage, with a high degree of advancement and large scale.
Product Functions
1. Effects on babies
Docose Hexanoic Acid Oil is considered to be an essential nutrient for early human development and an indispensable growth factor for the growth and development of infants and young children. If DHA is insufficient, it will lead to abnormal growth and development of fetal brain cells and central nervous system failure, affecting the acquired IQ index and normal metabolism. During pregnancy, the fetus itself cannot synthesize DHA and needs to be selectively transported from maternal plasma to the developing fetus via the placenta. Therefore, fetal DHA levels are closely related to maternal plasma DHA levels. Pregnant women need exogenous supplementation of DHA to ensure the health of the fetus in the second trimester.
2. Effects on adults
2.1 Delay aging and prevent senile dementia
The increase of DHA content in biofilm can improve the physiological function of the membrane, which is beneficial to enhance the transmission of neural information and improve the activity of the nervous system.
2.2 Protect the retina and improve vision
In human tissue cells, DHA accounts for the highest proportion in the retina, accounting for about 50%. Insufficient DHA in retinal tissue and the nervous system can lead to vision loss. Supplementing enough DHA can relieve dry eyes and protect vision.
2.3 Anti-inflammatory
DHA can regulate immune function by affecting the gene expression of cytokines or enzymes, inhibiting the production of pro-inflammatory factors, and regulating the expression of adhesion molecules, and has anti-inflammatory and anti-allergic effects.
Applications of Algal DHA oil
DHA Oil is widely used in infant formula, liquid milk, soft capsules, edible oil, and bakery food.
Infant formula and health food: Algae oil DHA is an important nutrient necessary for the brain and vision development of infants. Therefore, it is widely used in infant formula to provide necessary nutritional support for infants.
Healthy food: Algae oil DHA is also added to various products such as soft candies, nutrition bars, etc. to meet consumers' demand for a healthy diet.
Animal nutrition and feed: Algae oil DHA can improve the growth performance, immunity, and reproductive capacity of animals, which is of great significance to the development of the breeding industry.
Food and beverage: Algae oil DHA can be added to various beverages, yogurt, bread, and other foods to provide consumers with additional nutritional support.
As consumers pay more attention to a healthy diet, algae oil DHA has broad application prospects in the field of food and beverage.
Cosmetics and personal care products: Algae oil DHA can be used as a moisturizer, antioxidant, and other ingredients to help improve skin quality, delay aging, etc.
