The gardenia yellow pigment as a natural colorant has the characteristics of strong tinting strength, high safety, convenient use, bright color and the like, is widely used as a colorant for beverages, wines, dairy products, cosmetics and the like, and is a natural pigment which is mainly developed in recent years. The method for extracting and separating gardenia yellow pigment from gardenia fruit comprises solvent extraction method, supercritical fluid extraction method, ultrasonic extraction method and the like. The pigment obtained by the method contains other components in the raw material gardenia fruit, so that the obtained gardenia yellow pigment has peculiar smell. The invention patent of "gardenia yellow pigment for removing peculiar smell and manufacturing method thereof" (application publication number CN 102863814 a) applied by tianjin tiankang origin biotechnology limited in 2012 is characterized in that gardenia yellow is manufactured by selecting at least one method from the treatment methods of secondary adsorption treatment, ion exchange treatment, acid treatment and membrane separation treatment of the adsorption treatment liquid of gardenia yellow extract. The gardenia yellow of the present invention is a pigment having no odor or a slight odor, which is obtained by highly purifying gardenia yellow and has no odor in gardenia fruits or reduced odor. However, in the actual production, the gardenia yellow with the color value of 550 still has peculiar smell. The odor of the gardenia yellow is gradually intensified due to the influence of light and heat in the heating or long-term storage process. The phenomenon of "odor reversion" is caused by the presence of oil and fat in the pigment. The adsorption treatment, ion exchange treatment, acid treatment and membrane separation treatment of the gardenia yellow extract only remove other impurities. Therefore, we first performed experimental analysis from the source of off-flavor, then proposed solutions and put it to industrial practice.

Adopt above-mentioned technical scheme's beneficial effect: essential oil extraction and detection in the invention
1) Absorbent selection for simultaneous distillation extraction
Simultaneously, the distillation extraction method uses two absorbents, namely petroleum ether and diethyl ether, respectively, and selects the optimal reagent through essential oil detection.
According to the gardenia yellow extract: distilled water: petroleum ether or diethyl ether = 1: 2: 2, placing the gardenia yellow extract and water into a 1000-milliliter flask, oscillating, uniformly mixing, connecting to a simultaneous distillation and extraction device, accurately measuring petroleum ether (or diethyl ether), placing into a 250-milliliter round-bottom flask, connecting to the simultaneous distillation and extraction device, heating, distilling for 1 hour, and distilling the mixture of the raw materials and the water in the 1000-milliliter round-bottom flask at the reduced pressure of 60 ℃ for concentration. The collected substance from petroleum ether or diethyl ether in a 250 ml round-bottom flask was concentrated by distillation under reduced pressure to give a pale yellow substance, and the essential oil component was detected.
2) Determination of essential oil composition
The essential oil product obtained in step 1 was analyzed using a GC-MS instrument, the results are shown in the following table:
TABLE 1 GC-MS test chart for gardenia yellow pigment essential oil by simultaneous distillation and extraction method
The essential oil extracted by the simultaneous distillation and extraction method contains alcohols, alkenes and ketones such as alpha-pinene, phenethyl alcohol, 2-camphene, caryophyllene and the like, and the essential oil is consistent with the essential oil by using petroleum ether and diethyl ether as main components of an absorbent. Through data search and analysis, the substances have different smells and exist in various forms. Such as alpha-pinene, exists in various plant essential oils, can be used as a flavoring agent of some industrial products, and can be automatically oxidized in the air; phenethyl alcohol is commonly used in edible flavors, widely used in formulating soap and cosmetic essences, with a fresh floral taste; 2-camphene has a relatively pungent special flavor and the like. These substances all have special odor, and the existence of the substances can influence the odor of the gardenia yellow pigment product.
2. Fatty acid extraction and detection
1) Determination of fatty acid extractant
Respectively extracting fatty acid in the gardenia yellow pigment by adopting petroleum ether and diethyl ether (according to a Soxhlet extraction method), saponifying and performing methyl esterification treatment on the obtained product after extraction, and analyzing the fatty acid composition by adopting gas chromatography.
2) Determining fatty acid component in the sample
Respectively adopting petroleum ether and diethyl ether to leach fatty acid in the gardenia yellow pigment, and carrying out gas phase detection, wherein the results are as follows:
TABLE 2 Combined test chart for fatty acid gas in gardenia yellow pigment product extracted by different organic solvents
The results show that: the fatty acid in the gardenia yellow pigment mainly comprises palmitic acid, stearic acid, oleic acid, linoleic acid, eicosenoic acid and the like. The main components of the petroleum ether extraction and the ether extraction are basically consistent.
It can be seen that a large amount of lipid substances are present in gardenia yellow pigment. Lipid substances are easily oxidized and rotten under the influence of oxygen, temperature, light and the like, and meanwhile, alcohols, esters, aldehydes, ketones and the like generated by decomposition of fatty acids can generate peculiar smell of the gardenia yellow pigment.
3. Odor removal
Accurately measuring a certain amount of fructus Gardeniae yellow extract sample, placing in a container, adding appropriate amount of water, connecting with a steam distillation device, heating and distilling for 1 hr, refluxing, and performing oil-water separation to obtain essential oil and alcohol distillate (water essential oil). The water solution containing the pigment is filtered by a membrane with the molecular weight cutoff of 10 ten thousand to remove macromolecular compounds such as polysaccharide and the like. Adsorbing the permeate with AB-8 resin, eluting fat with ethyl acetate (the pigment is insoluble in organic solvent), eluting with 75% ethanol to remove gardenia pigment, and concentrating to obtain deodorized gardenia yellow pigment.
The invention has the following advantages:
1. the obtained essential oil is analyzed by a simultaneous distillation extraction method and a gas chromatograph-mass spectrometer, so that the odor is from the odor substances of the essential oil. The so-called odor reversion phenomenon is proved by Soxhlet extraction and gas chromatography analysis to be that the fat in the pigment is easily oxidized and decayed under the influence of oxygen, temperature, light and the like, and the gardenia yellow pigment generates odor due to alcohols, esters, aldehydes, ketones and the like generated by decomposing fatty acid.
2. The peculiar smell can be removed by adopting steam distillation and membrane treatment and using ethyl acetate as an eluant. The pigment has no peculiar smell, improves the color value and purity of the pigment, and improves the quality of the main component. The problem that gardenia pigment needs to be dried at ultrahigh temperature due to high viscosity during drying is solved after polysaccharide and fat are removed.
