What is Chlorella Extract Powder?
Chlorella Extract Powder is a functional ingredient, which is extracted and subsequently dried using spray-dry technology in order to retain the natural bioactive compounds of Chlorella, which is a freshwater green microalgae. It is said to be highly appreciated because of its abundance of chlorophyll, essential amino acids, nucleic acids, vitamins, minerals, and phytonutrients, which ensure that it is used broadly as raw material in various industries. Pharmaceutical companies working in dietary supplements and functional foods use it to develop tablets, capsules, nutrition bars, beverages, and protein blends that help in the overall nutritional fortification and product diversification. It is also incorporated into the feed and aquaculture industries in the form of a premium additive because of its protein content, pigmentation ability, and capacity to promote pig growth and livelihood in livestock and fish. Also, the cosmetic and personal care industries utilize in their skincare products, where it contributes to the antioxidant profile of the ingredient and to the natural pigmenting properties to produce premium products in skin health and natural beauty product development. It is a fine powder, so it can be mixed easily, spread evenly, and be compatible with many production systems, and hence it can be used in OEM and ODM customization.

Features
Chlorella Extract can be identified by its deep green color due to extremely high content of chlorophyll, which is one of the most striking physical properties of this microalgae-based ingredient. The powder is usually finely and homogenously structured and can be easily soluble and dispersible in both dry and liquid formulations, and is versatile in various manufacturing processes. Chemically, it is made of a balanced mix of proteins, peptides, essential amino acids, fatty acids, nucleic acids, vitamins, and minerals, which is utilized as a result of dense nutrient content that can be found in Chlorella naturally. It also possesses stable antioxidant compounds, which are also of functional value, including carotenoids and lutein. In comparison to other plant powders, it has good pigmenting ability owing to its high levels of chlorophyll and natural green pigments that not only make it attractive to the eye of the end products but also indicate its high levels of biochemical contents. The extract is stable in standard storage conditions and provides high stability in batch-to-batch consistency, which is extremely essential in large-scale processes by industries.
How to Store Properly?
1. Keep in a Cool, Dry Environment
The powder should be stored in a warehouse or other storage facility with controlled temperature and humidity. A moist environment can impair the flowability of the powder and stability of nutrients; hence, a dry environment is necessary.
2. Avoid Direct Sunlight and Heat Sources
Store the product in locations that are not in direct contact with the sun, heating systems, or in locations that are likely to have temperature variations. Excessive heat or light can also cause sensitive compounds to degenerate, like chlorophyll and carotenoids.
3. Seal Tightly After Opening
When the initial package has been opened, it must be sealed again or the remaining content must be put in air-tight containers to avoid oxidation, contamination, or absorption of moisture in the environment.
4. Protect from Strong Odors and Chemicals
Powder was capable of picking up external smell, and thus it must be kept away from any volatile substances, cleaning agents, or anything that smells strong to retain its original properties.
5. Follow FIFO Principle (First In, First Out)
Manufacturers should observe FIFO best practices and use older batches before new ones so that they maintain a consistent performance and freshness of Chlorella Vulgaris Extract.

Recommended Usage
It is a consistent and versatile raw material that is used by manufacturers in various sectors because of its stable composition and versatility. It is also a useful component in the nutraceutical and health food industry to blend into a formulation, nutritional powder, meal replacement, and fortified beverages with its dense matrix of micronutrients to position the product. Its application in animal nutrition and aquaculture has been to combine with special feeds to supplement protein content and offer the benefits of natural pigmentation, which can be used to promote product quality. Another area where Chlorella Liquid Extract is used is the cosmetic and personal care sector, where it is used in the formulation of creams, masks, and serums to exploit the pigment profile and natural actives present in it to build high-value products. Moreover, as it can be implemented in the creation of new product segments that encompass, e.g., plant-based supplements, wellness drinks, and more functional snack varieties, the product can be universally applied by any manufacturer planning to diversify their portfolios with natural, algae-based products.
