Carrot Red (Raphanus sativus L.) is made from carrot roots, extracted and refined, and can be used as a food additive in powder or liquid form, diluted with dextrin. It is a deep red solution with a slightly peculiar odor. It is not soluble in polar solvents such as ethanol, acetone, chloroform, and carbon tetrachloride, but soluble in water. The water solution is bright red in acidic solution, stable in color, and does not change color after prolonged boiling. No precipitation occurs in the solution. In alkaline solution, the color is unstable. Upon changes in pH: the color of the pigment changes with changes in the pH of the solution, ranging from orange-red to purple-lavender to blue in the pH 1-8 range, with red being the stable color in the pH 1-6 range, and the color becoming blue and less stable as pH exceeds 7; it does not fade under scattering light or artificial light over a long period of time; it has strong heat resistance and does not change color after prolonged boiling. ...

Gardenia blue is a kind of natural blue pigment extracted from the fruit of Gardenia jasminoides in the family of Rubiaceae, which has unique chemical properties and wide application value. As the food natural pigment approved to be used by GB2760-2011 Hygienic Standard for the Use of Food Additives in our country, Gardenia blue  is highly favoured in the field of food, medicine and cosmetic with its natural source and safety. Basic properties and production process  Physicochemical properties: Colour range: from sky blue to sea blue (hue can be adjusted by process)  Solubility: easily soluble in water, aqueous ethanol and aqueous propylene glycol  pH stability: stable hue in the range of pH4-8, excellent acid-resistance (still remain stable under the condition of pH2.5)  Thermal stability: no fading by heating at 120℃ for 60 minutes  Sensitivity: meet Fe²⁺ or Sn² ⁺ ions are easy to produce colour change  Main components: Containing carotenoids such as...

 Phycocyanin, a blue-green pigment protein derived from algae such as Spirulina, belongs to the phycobiliprotein family and is responsible for capturing and transmitting light energy in photosynthesis. This natural substance has attracted attention because of its distinctive blue colour and diverse biological activities, and is widely used in various fields such as food, medicine and cosmetics. Basic Properties and Chemical Composition  Algae blue protein appears as dark blue granules or powder, belongs to protein-binding pigments, and has the same properties as proteins. Its isoelectric point is 3.4, soluble in water but insoluble in alcohol and oil. This pigment is sensitive to heat, light and acid, and remains stable in weakly acidic and neutral environments (pH 4.5-8), precipitates under acidic conditions (pH 4.2), and decolourises in strong alkaline environments. In terms of chemical structure, phycocyanin consists of de-coordinated proteins covalently bound to phycobili...

 Nicotinamide mononucleotide, also known as β-nicotinamide mononucleotide, has the English name β-Nicotinamide Mononucleotide, and is abbreviated as NMN. The following is a detailed introduction:  Basic Information Molecular Formula: C11H15N2O8P.  Molecular weight: 334.221 g/mol. CAS number: 1094-61-7.  Physiological functions Cellular energy metabolism: It is a direct precursor of coenzyme NAD+, which plays a crucial role in cellular respiration, promoting the oxidation of glucose, fats, and amino acids to provide energy for the body.  DNA Repair: NAD+ is involved in the DNA repair process. NMN can enhance the DNA repair capacity of cells by increasing NAD+ levels, reducing the accumulation of DNA damage, and helping to maintain genomic stability. Immune Regulation: NAD+ plays a crucial role in immune responses. Supplementing NMN can raise NAD+ levels in the body, thereby strengthening the immune system's function and helping the body better resist diseases. Im...

The reason why Organic Spirulina Powder is highly respected is that it is rich in nutrients. Studies have shown that the nutritional value of 1 gram of spirulina (only in terms of vitamins) is equivalent to the sum of 1000 grams of various fruits and vegetables. Here are the main nutrients and benefits:   1. High-quality protein: The protein content of spirulina is extremely high, 6 times that of eggs. Its protein variety is complete, easy for the body to absorb and use, is an ideal protein source for vegetarians and athletes.   2. B vitamins: Spirulina is rich in B vitamins, especially vitamin B12, which is especially important for vegetarians because vitamin B12 is mainly found in animal foods.   3. Vitamin E (tocopherol) : Vitamin E is a powerful antioxidant that helps protect cells from free radical damage and slows aging.   4. Phycocyanin: This is a unique blue pigment that not only gives spirulina its unique color, but also enhances the immune function of huma...

  In the process of exploring the endless treasures given to us by nature, the ancient and magical plant elderberry (Sambucus nigra) has gradually come into the view of modern people with its rich medicinal value and unique skincare benefits. Elderberry  extract as a natural skin care ingredients, with its unique charm in the field of skin care set off a fresh wind.
