Embodiment 1

[0019] Embodiment 1: The industrial method for producing lycopene by utilizing tomato pomace adopts the following process steps.

[0020] 1. Weigh 1000kg of tomato skin residue, and carry out 6 times of hydrocyclone separation continuously to obtain tomato skin; after the tomato skin sample is dried, it is detected that its seed content is 0.26wt%;

[0021] 2. Use a ball mill to pulverize tomato peels to 180-200 meshes, and then add water to adjust to tomato peel pulp with a water content of 53.3wt%.

[0022] 3. Add 3 times the volume of n-hexane to the tomato pulp, and extract 3 times at 32°C, for 1.5 hours for the first time, and 0.5 hours for the second and third times; stand still after each extraction Layering and separating the extracts, and finally merging the extracts obtained three times;

[0023] 4. Concentrate and deodorize the combined extract to obtain 3.83kg of lycopene with a content of 6.87wt%.

Embodiment 2

[0024] Embodiment 2: The industrial method for producing lycopene by utilizing tomato pomace adopts the following process steps.

[0025] 1. Weigh 1000kg of tomato skin residue, and carry out 5 times of hydrocyclone separation continuously to obtain tomato skin; after drying the tomato skin sample, it is detected that its seed content is 0.08wt%;

[0026] 2. Use a ball mill to pulverize the tomato peel to 150-170 mesh, and then add water to adjust it to a tomato peel slurry with a water content of 55.0wt%.

[0027] 3. Add 4 times the volume of No. 6 light gasoline to the tomato pulp, extract 4 times at 33°C, the first time is 2.0 hours, and the last three times are 1.0 hours; Separate the extract, and finally combine the extracts obtained four times;

[0028] 4. The combined extract was concentrated and deodorized to obtain 3.13 kg of lycopene with a content of 8.80 wt%.

Embodiment 3

[0029] Embodiment 3: The industrial method for producing lycopene by utilizing tomato pomace adopts the following process steps.

[0030] 1. Weigh 1000kg of tomato peel residue, and carry out 4 times of hydrocyclone separation continuously to obtain tomato peel; after drying the tomato peel sample, detect that its seed content is 0.28wt%;

[0031] 2. Use a ball mill to pulverize the tomato peel to 160-180 mesh, and then add water to adjust it to a tomato peel slurry with a water content of 50.0wt%.

[0032] 3. Add 2 times the volume of n-hexane and 2 times the volume of petroleum ether to the tomato pulp, extract 5 times at 35°C, the first time is 2.5 hours, and the last four times are 0.5 hours; Separate the extract with a tube centrifuge, the separation factor is 15000, and finally combine the extracts obtained five times;

[0033] 4. The combined extract was concentrated and deodorized to obtain 3.50 kg of lycopene with a content of 7.03 wt%.

Abstract

The invention discloses an industrial method for producing tomato red by using tomato peel residues. The method comprises the following process steps of: (1) performing hydrocyclone separation on the tomato peel residues containing tomato seeds to obtain tomato peel, wherein the seed content of dried tomato peel is below 0.3 percent by weight; (2) smashing the tomato peel, and adjusting into tomato peel paste with 50-55 percent by weight of water; (3) extracting the tomato peel paste with an organic solvent, and separating to obtain an extracting solution, wherein the organic solvent is n-hexane, No.6 light petrol and / or petroleum ether; and (4) concentrating and deodorizing the extracting solution to obtain tomato red. Due to the adoption of the method, high-quality natural tomato red can be obtained; and the method has the advantages of simple process, short flow, small loss, high yield, low comprehensive cost, good product quality and easiness for realizing continuous industrial production.

Description

technical field [0001] The invention relates to a preparation method of lycopene, in particular to an industrial method for producing lycopene by using tomato pomace. Background technique [0002] Lycopene mainly exists in the ripe fruit of tomato, a plant of the family Solanaceae. Tomato red is a natural antioxidant and one of the strongest antioxidants found in nature. 1. It is famous for its superior antioxidant function and has been widely recognized by domestic and foreign consumer groups. [0003] From the mechanism of action, lycopene relies on its functional component lycopene to play a role. By quenching the singlet oxygen and oxygen free radicals in the human body, it prevents its damage to the human body's own immune system, and achieves anti-oxidation, anti-aging, and enhancement. Immunity etc. In terms of effect, lycopene is far superior to other carotenoids and vitamin E in scavenging free radicals, and its singlet oxygen quenching rate constant is 100 times ...
