[0039] 3) Mix the filter residue in the above step 2) with 300 ml of ethyl acetate, extract homogeneously at 3000 rpm for another 20 minutes at 25° C., and filter.

[0040] 4) Combine the two filtrates, centrifuge at 1000 rpm for 10 minutes, remove the precipitate, and collect the supernatant.

[0041] 5) Concentrate in vacuo and freeze-dry to form a powder to obtain 12.08 mg of crude lycopene (color: bright red), including 64.8 mg of lycopene, with an extraction rate of 98.6%.

Embodiment 2

[0043] 1) Take fresh tomatoes, crush them with a fruit juice machine, dry them, and crush them to 50 mesh to obtain tomato powder for later use.

[0044] 2) Weigh 100 grams of tomato powder, add 500 milliliters of ethyl acetate, pretreat at 9,000 rpm for 10 minutes at 25° C., extract homogeneously at 4,000 rpm for 10 minutes, and then filter.

[0045] 3) Mix the filter residue in the above step 2) with 500 ml of ethyl acetate, extract homogeneously at 4000 rpm for 10 minutes at 25° C., and filter.

[0046] 4) Combine the two filtrates, centrifuge at 2000 rpm for 5 minutes, remove the precipitate, and collect the supernatant.

[0047] 5) Concentrate in vacuo and freeze-dry into powder to obtain 121.3 mg of crude lycopene (color: bright red), including 65.3 mg of lycopene, with an extraction rate of 98.8%.

Embodiment 3

[0049] 1) Take fresh tomatoes, crush them with a fruit juice machine, dry them, and crush them to 50 mesh, and set aside.

[0050]2) Weigh 100 grams of tomato pulp (same as above, same as above), add 1000 ml of ethyl acetate, pretreat at 10,000 rpm at 25°C for 10 minutes at high speed, then extract homogeneously at 1,000 rpm for 30 minutes and then filter .

[0051] 3) Mix the filter residue in the above step 2) with 1000 ml of ethyl acetate, extract homogeneously at 1000 rpm for 30 minutes at 25° C., and filter.

[0052] 4) Combine the two filtrates, centrifuge at 500 rpm for 15 minutes, remove the precipitate, and collect the supernatant.

[0053] 5) Concentrate in vacuo and freeze-dry into powder to obtain 118.5 mg of crude lycopene (color: bright red), including 64.1 mg of lycopene, with an extraction rate of 98.5%.

Abstract

The invention discloses an extraction process for lycopene. The extraction process for lycopene comprises the following steps of: (1) breaking tomato into pieces, drying, and then crushing; (2) mixing the crushed tomato with ethyl acetate, performing high-speed pre-treatment and homogeneous extraction at a constant temperature, and then filtering; (3) mixing the filter residue with ethyl acetate, performing homogeneous extraction at a constant temperature, and then filtering; (4) combining the filtrates, centrifuging, and collecting the supernatant; and (5) freeze-drying to obtain lycopene, wherein the high-speed pre-treatment is performed for more than 5 minutes at a speed of 5000-10000 r/min; the homogeneous extraction is performed for more than 10 minutes at a speed of 1000-4000 r/min; and the rotational speed of the centrifuging is 200-2000 r/min. The invention further discloses a lycopene extract extracted by the extraction process. According to the extraction process disclosed by the invention, the traditional extraction method is improved, ethyl acetate is used for extracting, the extraction effect is good, toxic hazard on human body is avoided, the solvent is easy to recover, the extraction rate for lycopene is increased while the extraction cost is not increased, and a foundation is laid for expanding the industrial application value of lycopene.

Description

technical field [0001] The invention belongs to the technical field of natural pigment extraction, and in particular relates to a lycopene extract and an extraction process thereof. Background technique [0002] Lycopene (Lycopene) is a commonly used pigment extracted from ripe tomatoes, and it is a unique ring-shaped carotenoid that does not contain oxygen. Lycopene is widely distributed in nature, mainly in tomato, and also in watermelon, pumpkin and grapefruit. [0003] The lycopene in tomato and its products is the main source of carotenoids in the western diet, and the lycopene obtained by the human body from tomato accounts for more than 80% of the total intake. As early as 1873, Hartsen first isolated the red crystals of lycopene from the berry yam (Tamuscommunis L.), one of the strongest antioxidants found in nature. [0004] Lycopene has a strong ability to scavenge free radicals. The ability to scavenge singlet oxygen is 100 times that of vitamin E, a commonly us...
