Embodiment 1

[0016] Embodiment 1, the preparation method of lycopene

[0017] Weigh 30kg of mature tomato and beat it, centrifuge the slurry at 3500r / min for 30min, dry the sediment after centrifugation in a vacuum drying oven at 38°C for 12 hours, grind it with a colloid mill, put the ground tomato sample into the extraction kettle, and close the lid of the kettle. Control the temperature of the reactor to 40°C and the pressure to 30Mpa, and introduce supercritical carbon dioxide fluid, and circulate the extraction for 1 hour; then change the temperature and pressure of the reactor so that the temperature of the reactor is 70°C, and the pressure is 35Mpa, and continue the extraction for 1 hour; the amount of carbon dioxide : 10L / 1kg (volume of carbon dioxide / weight of tomato); after the extraction is completed, reduce the pressure to 4.5Mpa, separate the extracted substance, and spray dry to obtain 4.2g orange-red powder.

Abstract

The invention discloses a preparation method of lycopene, which comprises the following steps of: 1. pulping a tomato, centrifuging a serous fluid, drying deposits obtained through centrifugalization and then grinding to obtain a tomato sample; 2. loading the tomato sample into an extraction kettle, carrying out supercritical carbon dioxide extraction by introducing a supercritical carbon dioxide fluid into the extraction kettle, and decompressing to 3.5-5.0MPa to obtain the lycopene, wherein the supercritical carbon dioxide extraction is divided into two steps, the temperature of the extraction kettle when in extraction in the first step is 40-70 DEG C, the pressure is 10-30MPa, the temperature of the extraction kettle in the second step is 50-80 DEG C, and the pressure is 15-35MPa. In the preparation method of the lycopene, an organic solvent is not used, the extraction efficiency is greatly improved, and the lycopene with higher purity can be obtained.

Description

technical field [0001] The present invention relates to a kind of preparation method of lycopene, especially relate to a kind of using supercritical CO 2 Technical process for the preparation of lycopene. Background technique [0002] Lycopene is a fat-soluble natural pigment and a kind of carotenoid. It has the functions of anti-oxidation, scavenging peroxide free radicals, anti-cancer, anti-cancer, delaying aging, and preventing and treating cardiovascular diseases. Its antioxidant properties are in The strongest among carotenoids, the ability to scavenge singlet oxygen is 100 times that of the currently commonly used antioxidant VE, and more than twice that of β-carotene. At present, it has been identified as a type A nutrient by the United Nations FAO / WHO United Nations Committee on Food Additives (JECFA), and is widely used in health food, medicine and cosmetics. Lycopene is a natural red pigment used in many foods. Especially developed countries advocate the use of ...
