China Red Clover Extract Powder

China Red Clover Extract Powder is a botanical ingredient that is made from flowers and aerial parts of Trifolium pratense, with standardized extraction, concentration, purification processes, and spray drying to ensure uniformity and free-flowing powder, which can be used in the formulation of products in the industry. Typically normalized to a specific amount of isoflavone per unit, as needed by the formulation of the customer, assuring batch-to-batch consistency in the manufacturing of dietary supplements, functional foods, beverages, and personal care products. The professional manufacturers generally adopt very strict raw materials identification and management, stable production process, and a complete quality control system, to meet the expectations of the international market and deliver the stability of appearance, purity, and processing performance. With an established supply chain for botanicals, a scalable production capacity, a flexible production capacity to customize specifications, and an efficient export system to the overseas market, China has become an important production base for it. The ingredient is compatible with a variety of formulation systems, which allows for use in capsules, tablets, powder blends, instant drink mixes, gummies, liquid concentrates, and value-added formulations.

Red Clover Extracts' main active ingredients are naturally occurring isoflavones, which are known to be the most important standardized ingredients for product quality and consistency in commercial production. The most significant isoflavones are biochanin A and formononetin, which typically occur in the highest amounts and are the primary marker compounds in many standardized extracts. There are several additional naturally occurring isoflavones in the extract, such as genistein and daidzein. In addition to isoflavones, it contains naturally occurring flavonoids, phenolic compounds, polysaccharides, amino acids, and trace minerals, which vary in levels based on the botanical source, extraction technology, and level of standardization. In terms of manufacturing and procurement, the sum of the isoflavones is the most important quality specification that gives a measurable indication of the extract concentration, batch-to-batch consistency, and formulation suitability. Therefore, it is typically standardized to a specific amount of total isoflavones to assure both ingredient suppliers and finished-product manufacturers a consistent quality control, predictable processing properties, and formulating flexibility, whether in a dietary supplement, functional food, or personal care product.

1. Raw Material Selection

The plant material-flowers and aerial parts of Trifolium pratense-is obtained from qualified suppliers, and pre-production quality parameters and basic botanical identity are examined.

2. Cleaning and Grinding

Foreign material is removed from the raw material, and the material is crushed to a proper particle size, thus increasing the surface area for an efficient extraction.

3. Hydroalcoholic Extraction

A food-grade ethanol-water extract solution is used to extract the processed botanical material at a controlled temperature and time. This is the most commonly used commercial process since it allows efficient recovery of naturally occurring isoflavones, and it can be used to manufacture on a large scale.

4. Filtration and Concentration

This extract solution is filtered to separate it from the plant residue, and the extract is concentrated under reduced pressure by removing excess solvent, thus increasing the solid content in the extract, which is then used for further processing.

5. Purification and Standardization

The extract is concentrated, then purified (often using "food grade" adsorption resin technology) and standardized to the required specification for isoflavones for consistent product quality and batch uniformity.

6. Spray Drying

After spraying the standardized liquid extract to make a fine powder, the extract is subjected to spray drying. Where required, appropriate food-grade carriers are added to enhance powder stability, flowability, and processing.

7. Milling and Quality Control

The dried powder is milled and sieved to achieve uniformity in particle size and then subjected to extensive quality testing, such as appearance, assay, moisture, microbiological limits, heavy metals, and all other applicable specification limits.

8. Packaging and Storage

Trifolium Pratense Extract is packed in moisture-resistant export packing and kept in a cool, dry storage and warehousing space, away from heat, humidity, and light to ensure product stability during storage and international shipping.

The product development applications of Clover Flower Extract typically involve the use of the extract powder in final products targeted towards adult consumer markets, where the client is looking for a plant-based botanical ingredient for their daily nutritional and wellness routine. It is commonly used by brand owners and manufacturers of botanical supplements, as well as powdered beverage blends, gummies, capsules, tablets, and carefully made personal care products made from natural ingredients. Its botanical source and standardized isoflavone profile make it a good fit for use in product portfolios geared towards higher quality plant-based, clean label, and naturally sourced products where consumers prefer to use products made with traditional botanical extracts. It can be used in a wide range of dosage forms, markets, and has broad formulation flexibility for manufacturers for private label, private branding, OEM, and contract manufacturing projects for general adult consumers.
