Method for extracting blackberry pigment
InactiveCN101255280AShorten the concentration timeReduce lossesNatural dyesFood preparationNutrientSolubility
An extracting method of blackberry pigment relates to a technique for producing natural blackberry pigment using fresh or frozen blackberry. The natural blackberry pigment has bright color, stable quality, rich nutrient and widely used in every field of food industry. Because the maturation period of the blackberry is centralized and the blackberry is not easy to store, the factory run is used to process the fresh blackberry into pigment powder during collection period; or the factory run is used to process the frozen blackberry into pigment powder during dead period of production. The preparation method comprises heating and softening the fresh or frozen blackberry, crushing, extracting, decompression concentrating, adjusting pH, diluting, centrifuging, purifying, decompression concentrating, drying and grinding. The invention provides a safe and effective method for extracting and purifying the blackberry pigment to obtain natural pigment with high purity, good chemical stability and strong water solubility.
