Abstract

The invention discloses a method for extracting passion flower fruit pigment from passion flowers. The extraction method comprises the following steps: treating raw materials, sequentially carrying out high pressure treatment, ultrasonic wave extraction, supercritical CO2 fluid extraction, and drying so as to obtain the finished product. Compared with the prior art, the extraction method has the advantages that the passion flower raw materials are directly subjected to column chromatography adsorption, and the production process is simple and short in time.

Description

technical field [0001] The invention relates to a preparation method of a pigment, in particular to a method for extracting a passion fruit pigment. Background technique [0002] Passiflora (scientific name: Passiflora caerulea L.) is a fragrant and delicious fruit, known as the "King of Juice". It is a perennial evergreen climbing woody vine. Bright, fragrant smell, sweet and sour fruit, fruit aroma, edible fruit pulp, sweet and sour. Intense flavor and pleasant aroma. Passiflora originated in Brazil, and later it was planted in South America, South Africa, Southeast Asian countries, Australia and the South Pacific. Because the fruit of passion fruit is shaped like an egg, the juice color is like egg yolk and has the flavor of pineapple, guava, banana, mango, grass poison, watermelon, sour plum, sugar cane and peach and plum, so there are also egg fruit, Known as passion fruit. The whole body of passion fruit is full of treasures. According to the determination, the fru...
