Introduction	Food additive quinoline yellow as a synthetic food pigment, bright color, low price, therefore, it is widely used by food manufacturers. Quinoline yellow is a water-soluble azo synthetic pigment, which is commonly used in the UK for ice creams, fruits, cakes, chocolate, bread, cheese sauce, soft drinks and other food coloring. Because the pigment may lead to ADHD in children, Japan, the United States and Norway are banned in food, while China only allows to add in the preparation of wine, and the maximum use of 0.1g/L.
properties	Food additive quinoline yellow is composed of 2-(2-quinoline group)-1,3-indanedione or 2/3 2-(2-quinolyl)-1,3-indanedione and 1/3 [2-(6-methylquinolyl)]1, A mixture of 3-indanedione was prepared by sulfonation. Quinoline yellow is a yellow powder or granule, soluble in water and slightly soluble in ethanol. Ejfa specifies quinoline yellow ADI as 0-10mg/kg body weight, and its ADI value was first established in 1984. Quinoline yellow can be used as a coloring agent (edible yellow pigment) in the food industry.
determination of content	1. Method summary use phosphate buffer solution (pH = 7) for quinoline yellow sample after dissolving, diluting the volume, at the maximum absorption wavelength, measure the absorbance value to calculate its content. 2. Preparation of sample solution weigh about 0.25g of Quinoline Yellow sample (accurate to 0.0001g), dissolve it in appropriate amount of phosphate buffer solution, and transfer it into a 1000mL volumetric flask, dilute to scale with phosphate buffer solution and shake. 10ml was aspirated, transferred into a 250ml volumetric flask, diluted to the mark with phosphate buffer solution, and shaken until use. 3. Analysis steps The sample solution of Quinoline Yellow is placed in a 10mm Cuvette, and its absorbance value is measured with a spectrophotometer at the maximum absorption wavelength, phosphate buffer solution was used as reference solution. Quinoline Yellow content is W1, expressed as%, calculated by the following formula: 4, calculated as result W1 =(A · f · 1000)/(a · m)× 100% absorbance value of A- quinoline yellow sample solution; f-dilution factor of Quinoline Yellow sample solution;
Use	edible yellow pigment.
production method	from 2-(2-quinolyl)-2, 3-dihydro-1, 3-indanedione or from 2-(2-quinolyl)-2, 3-dihydro-1 containing about 2/3, 3-indanedione and 1/3 of 2-[2-(6-methylquinolyl)]-2, 3-dihydro-1, A mixture of 3-indanedione was obtained by sulfonation.
