Physical and Chemical Properties | Red to dark purple liquid, block, powder or paste-like substance, slightly with special odor. Soluble in water, ethanol, propylene glycol, insoluble in oil. The Hue varies with the Ph. Acidic red to purple, alkaline dark blue, dark purple in the presence of iron ions. Dyeing, heat resistance is not too strong, vitamin C can improve its light resistance. The color tone is stabilized by polyphosphate. |
In vitro study | Enocyanin (0.1%) affects the leucine aminopeptidase, acid phosphatase, γ-glutamyl transpeptidase and esterase activity by 63%, 100%, 134% and 99%, respectively. |

Function | linarin, whose English name is Linarin, belongs to flavonoids. The linarin has anti-staphylococcus aureus and hemolytic streptococcus, anti-aging effect, anti-hypoxia effect, anti-adverse stimulation effect, two-way regulation effect on the body, anti-fatigue effect, inhibition of blood sugar rise?, toxicity and mutagenicity teratogenicity research, on learning and memory effects. |
use | coloring is suitable for coloring acidic beverages, wine, jam, jelly and other foods. coloring agent (red to red purple). For beverages, cold drinks, alcoholic beverages, cakes, jams, etc. The dosage of beverage, wine, jam and liquid products is 0.1% ~ 0.3%. The addition amount of powder food was 0.05% ~ 0.2%. Ice cream 0.002% ~ 0.2%. |
biological activity | Enocyanin are anthocyanins obtained from grapes. Enocyanin can affect the activities of leucine aminopeptidase, acid phosphatase, γ-glutamyl transpeptidase and esterase. |
target | Acid phosphatase |
Production method | The peel (residue after making grape juice or wine) is obtained by removing the seeds, extracting the peel with water, refining and vacuum concentration after extracting the peel from the grape vinifera (Vitis labrusca) and other grape fruits. Powdered products use maltodextrin, modified starch or colloid as carriers. |
