Few direct coloring in food processing, and is mainly used for natural yellow pigment such as gardenia yellow pigment, safflower yellow pigment, such as compatibility, allocate different colour and lustre is green, compared with the extraction of chlorophyll, use gardenia blue pigment mix green plain can control, good resistance to acid, can be used for partial acid in food and lycopene for skin beverage. Gardenia blue pigment also can compatibility with all kinds of natural red pigment, the deployment of a different color of purple. Therefore, gardenia blue pigment in food processing has a wide application scope.
Gardenia blue pigment due to the difference of the processing technology, can obtain different shades of blue, the color from blue to blue, and acid and acid resistant varieties, suitable for different application environment. The natural blue pigment is rare in nature, gardenia blue pigment is one of them, compared with the synthetic pigment consumption of bright blue, indigo, the source of natural, human body good compatibility, high reliability. Is a kind of natural pigment is worth promoting. Gardenia blue pigment in food, beverage, cosmetics mulberry leaf extract weight loss added cost is not high, the usage of between zero point zero zero five percent and zero point zero one percent, but compared with the synthetic pigment, synthetic pigment in food processing unit cost is almost zero, it is because the price is cheap, synthetic pigment in food abuse, the phenomenon of excessive use, it is bad for people's health.
Chlorophyll is can all higher plants and other photosynthetic organisms contain a kind of green pigment. Chlorophyll a and chlorophyll b are soluble in ethanol, ether and acetone solvent, insoluble in water and petroleum ether, therefore, can use the polarity solvent such as acetone, methanol, ethanol, ethyl acetate extract chlorophyll, etc. Extract: chlorophyll extracted preparation is in one and a half dark room, room temperature at 25 ℃. Extract the steps as follows:
Take 1000 grams of fresh green leaves, Webster's shattered in the cutting machine. Put 1000 grams, green leaves of crushing in acetone with a small amount of calcium carbonate added in extracting temperature (20 ℃), until after filtering, cleaning leaf fragments to colorless. Will filter the acetone extract in the petroleum ether containing 1 and 100 ml of acetone in the funnel, and then gently phycocyanin spirulina rotate, at the same time put distilled water until stratification. Most of the water layer of acetone and water soluble impurities are discarded, with petroleum ether solution. The petroleum ether solution with distilled water after purification, again by petroleum ether and 0.01 grams of 200 m per l80 oxalic acid methanol solution cleaning more than five times, yellow-green suspension.
With anhydrous sodium sulfate to dry suspension, and its infiltration into 3 cm thick cane sugar powder column, and then clean with petroleum ether precipitation pigment remove the carotenoids, contain natural chlorophyll. Sucrose column is divided into two layers with natural chlorophyll, the green layer has 4 -- 10 mm chlorophyll b, another blue layer for chlorophyll a layer 2-6 mm. Will be located in the blue parts of the layer is (about half of the blue layer) into the ether, the suspending liquid filtering, washing, clean with distilled water and dry with sodium sulfate, reoccupy vessel after filtering, chlorophyll a. Will be removed in the middle of the green layer, quickly into the ether filtering, elution, made of chlorophyll b ether solution.
Separation: chromatography is a kind of very good isolation, purification and identification of the important methods for organic compounds, especially is widely applied in trace analysis. Fruits and vegetables mainly include the fat-soluble pigment in beta-carotene, lutein, chlorophyll and soluble anthocyanin. In extraction experiments, we can make use of the principle of similar miscibility of rosmarinic acid supplement water-soluble anthocyanin filtering, which in turn can make use of thin-layer chromatography, column chromatography, chromatography for separation, beta-carotene, lutein and chlorophyll weakened due to the polarity of the three types of pigment in turn, can be appropriately choose single organic solvent or different ratio of mixed solvent as developing solvent and eluant, better optimization of separation conditions were determined.
