Baisfu chlorophyll copper sodium salt is used as a natural green pigment in baking, dairy products, and pastries

Sodium copper chlorophyllin is a natural water-soluble pigment (mainly a mixture of sodium copper chlorophyllin a and b) obtained from the chlorophyllin of plants (such as spinach, silkworm excrement, and alfalfa) through saponification and copperification reactions. Its core characteristics are a stable green hue and natural origin. It also possesses multiple functions including coloring, antibacterial properties, and antioxidant effects, and is widely used in the food and daily chemical industries. It is a classic natural pigment that combines safety and practicality.

Chemical Composition: Primarily composed of sodium copper chlorophyllin a (C₃₄H₃₁CuN₄NaO₆) and sodium copper chlorophyllin b (C₃₄H₃₀CuN₄NaO₇), which are isomers. In commercial products, the ratio is approximately 3:1. Purity is typically ≥95% (food grade/daily chemical grade), free of complex and harmful impurities.

Physical Properties: At room temperature, it is a blue-black powder or dark green crystals. It is readily soluble in water, producing a bright blue-green aqueous solution. It is slightly soluble in organic solvents such as ethanol .It exhibits good heat resistance, remaining color stable in processing environments below 100℃. Under light, it is less prone to fading than natural chlorophyllin.

Chemical Properties: Its stability is significantly superior to natural chlorophyllin. It exhibits strong acid and alkali resistance (color stable within a pH range of 3-11) and is not easily oxidized or decomposed. However, it may change color upon contact with strong oxidizing agents or heavy metal ions; therefore, it should be stored away from these substances.

• Food and Beverage Sector

  Food Coloring: Widely used in pastries, candies (such as green hard candy and soft candy), jellies, ice cream, dairy products (such as matcha-flavored yogurt and green milkshakes), meat products (such as imitation crab meat and fish balls), and vegetable products (such as pickles and preserved vegetables), giving them a natural green color and enhancing their sensory appeal.

  Beverage Blending: Used in fruit juices, vegetable juices, carbonated drinks, dairy-based drinks, and plant-based protein drinks, replacing synthetic pigments to create a natural and refreshing green appearance and masking the dullness of some raw materials.

• Daily Chemicals Sector

  Personal Care Products: Added to shampoos, conditioners, shower gels, soaps, etc., giving them a natural green appearance. Its antibacterial and antioxidant properties can also help improve the scalp environment and relieve minor skin discomfort, aligning with the positioning of natural plant-based daily chemical products.

  Skincare Products: Used in masks, lotions, serums, etc., emphasizing the concept of "natural plant extracts." The green appearance enhances the product's natural feel, while also providing antioxidant and skin-soothing benefits, making it suitable for sensitive and acne-prone skin.

  Oral care: Used in small amounts in toothpaste, mouthwash, etc., to improve the appearance and color of the product. At the same time, its antibacterial properties can help freshen breath and inhibit harmful bacteria in the mouth.

1. Excellent coloring performance and wide compatibility: The color is bright and natural, a pure blue-green, accurately mimicking the natural color of plants, and has a more natural feel compared to synthetic green pigments (such as brilliant blue and lemon yellow blends); it disperses evenly in aqueous solutions, easily blending with food and daily chemical product systems without affecting the original texture and taste of the product.

2. Natural and safe, with strong compliance: Derived from plant chlorophyll, it is a natural food additive, complying with the usage standards of most countries and regions worldwide, including GB 2760 and the FDA; it is non-toxic, non-allergenic, and has good biocompatibility, safe for human use within the prescribed dosage, aligning with the consumer trend of "natural and healthy".

3. Multifunctional synergy and high added value: In addition to its coloring function, it also has certain antibacterial (inhibitory effect against Escherichia coli, Staphylococcus aureus, etc.) and antioxidant activities, which can help extend the product's shelf life; it also contains copper, which can be used as a micronutrient supplement to enhance product functionality.

4. The preparation process is mature and the supply is stable: the raw materials (plant waste or special crops) are widely available and low in cost. The extraction and conversion processes are mature (saponification removes fat-soluble groups, and copper ions replace magnesium ions to enhance stability). The output is large and the price is affordable, which can meet the needs of large-scale industrial production.
