Industrial Applications of GARDENIA YELLOW
| Industry | Application | Process |
|---|---|---|
| Food Industry | Natural food colorant for coloring bakery products, confectionery, beverages, ice cream, seasonings, etc. | Crocin and crocetin are extracted from gardenia fruit, purified and dried to produce powdered or liquid colorants, added within limits specified in GB 2760. |
| Pharmaceutical Industry | Secondary colorant for appearance coloring of tablets, capsules, and oral liquids. | Pharmaceutical-grade gardenia yellow colorant is sterilized and incorporated into formulations. |
| Cosmetics Industry | Natural colorant for coloring lipsticks, blushes, eyeshadows, and other color cosmetics. | Gardenia yellow colorant is blended with bases (e.g., oils, waxes) and processed via homogenization and grinding to yield stable colorants. |
| Textile Dyeing & Printing | Natural plant-based dye for dyeing natural fibers such as cotton and silk. | Dyeing is performed under weakly acidic or neutral conditions using mordanting (e.g., aluminum or iron salts) or direct dyeing processes. |
| Household & Personal Care Products | Colorant for soaps, body washes, toothpastes, and similar products. | The colorant is dissolved in water or glycerin, then homogenized and emulsified with other formulation components. |
Manufacturing Quality Control of GARDENIA YELLOW
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Color Value (E1%1cm at 440 nm) | UV-Vis Spectrophotometry | Measures absorbance of diluted solution at 440 nm to quantify color intensity per unit concentration. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration and weighing. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity using calibrated pH electrode in standardized solution. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Detects trace metal elements by ionization in plasma and mass spectrometric quantification. |
| Arsenic | Hydride Generation AAS | Converts arsenic to volatile hydride, then measures atomic absorption at characteristic wavelength. |
| Lead | Graphite Furnace AAS | Atomizes sample in graphite furnace and quantifies lead via absorption at 283.3 nm. |
| Microbial Limits (Total Aerobic Count) | Plate Count Agar Culture | Enumerates viable aerobic bacteria by colony formation on nutrient agar after incubation. |
| Yeast and Mold Count | Sabouraud Dextrose Agar Culture | Quantifies viable yeast and mold colonies on selective medium after controlled incubation. |
| Residual Solvents (Ethanol, Acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile solvents using capillary column and flame ionization detection. |
| Chlorinated Pesticide Residues | GC-MS | Extracts and identifies organochlorine pesticides via gas chromatographic separation and mass spectral detection. |
| Carmine Acid (Impurity) | HPLC-UV | Separates and quantifies carmine acid using reversed-phase HPLC with UV detection at 500 nm. |
