Problems solved by technology

[0004] It is known from the current domestic literature that in the lycopene extraction process, the moisture content of the raw materials is required to be lower than 15%, and even some patents require that the moisture content of the raw materials be as low as possible, but when the raw materials are dehydrated below 15%, lycopene The element content will be quickly oxidized and lost, and the loss of color value can be as high as 30%, resulting in a low total recovery rate. If the raw material moisture is too high, the extraction rate of conventional weak polar solvents is low

Embodiment 1

[0028] Take 50kg of tomato pomace, the color value is 0.56. After drying with a hot air dryer, the inlet air temperature is 200°C, the outlet air temperature is 60°C, the time is 10s, and the moisture content of the material is 45%. The seeds and skins are separated, and the tomato skins are dried in a fluidized bed at a temperature of 50°C for 100 seconds. They are milled and blown with cold wind to obtain tomato powder. The moisture content is 28%. The tomato powder is 9.5kg with a color value of 2.9 and a color value of 9.5 kg. The rate is 98.4%.

[0029] The obtained tomato powder was added to a 7-fold mixed solvent (butanone:n-hexane=24:76), and stirred and extracted 4 times in a water bath at 50°C, each time for 2 hours. Combine each extract, evaporate and concentrate under reduced pressure at a vacuum of -0.09MPa and a temperature of 45°C, and recover the solvent to obtain 329g of lycopene oleoresin with a color value of 83.2. The extraction yield of color value was 9...

Embodiment 2

[0031] Take tomato pomace 100kg, the color value is 0.63. After drying with a hot air dryer, the inlet air temperature is 400°C, the outlet air temperature is 90°C, the time is 20s, and the moisture content of the material is 35%. The seeds and skins were separated, and the tomato skins were dried in a fluidized bed at a temperature of 50°C for 40 seconds, then pulverized and blown with cold wind to obtain tomato powder with a moisture content of 15.0%. Obtain 14.7kg of tomato skin powder, the color value is 4.1, and the color value yield is 95.7%.

[0032] The obtained tomato powder was added to a 3-fold mixed solvent (acetone:n-hexane=15:85), and stirred and extracted 4 times in a water bath at 40°C, each time for 3 hours. Combine each extract, evaporate and concentrate under reduced pressure at a vacuum of -0.09MPa and a temperature of 45°C, and recover the solvent to obtain 700g of lycopene oleoresin with a color value of 85.7. The extraction yield of color value was 99....

Embodiment 3

[0034] Take 50kg of tomato pomace, the color value is 0.50. After drying with a hot air dryer, the inlet air temperature is 300°C, the outlet air temperature is 75°C, the time is 30s, and the moisture content of the material is 40%. The seeds and skins are separated, and the tomato skins are dried in a fluidized bed at a temperature of 45°C for 70 seconds. They are milled and blown with cold wind to obtain tomato powder. The moisture content is 21.4%, and 8.5 kg of tomato powder is obtained, with a color value of 2.9 and a color value of The rate is 98.6%.

[0035] The obtained tomato powder was added to a 5-fold mixed solvent (butanone:n-hexane=19:81), and stirred and extracted twice in a water bath at 45°C, each time for 2.5 hours. Combine each extract, evaporate and concentrate under reduced pressure at a vacuum of -0.09MPa and a temperature of 45°C, and recover the solvent to obtain 294g of lycopene oleoresin with a color value of 83.2. The extraction yield of color valu...

Abstract

The invention relates to an industrial producing method of lycopene oil resin. The method includes the following steps of firstly, preprocessing raw materials, wherein tomato peel dregs are dried by a hot air drier, tomato seeds and peels are separated, and tomato peels are dried and ground by a fluidized bed to obtain tomato powder; secondly, conducting extracting, wherein tomato powder is added to alkane and low-molecular ketone mixed solvent to be stirred and extracted under the water bath condition; thirdly, conducting concentrating, wherein an extraction solution is subjected to decompressed evaporation and concentration under the vacuum conditions, solvent is recovered, and then lycopene oil resin is obtained. Tomato peel dregs serve as the raw material, tomato powder is prepared through the high-temperature rapid drying method, and color value loss is little. Extraction of mixed solvent can adapt to the material with high water content, and the method is high in extraction yield, low in cost, more suitable for continuous mass production and remarkable in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of natural extracts, and in particular relates to an industrial production method of lycopene oleoresin. Background technique [0002] Lycopene, first obtained from ripe tomatoes, is one of the strongest antioxidants. Its health care effect is remarkable, and its antioxidant capacity is superior to other carotenoids. It is an excellent natural antioxidant. Lycopene has a variety of biological activities and is the main carotenoid present in the human body. In recent years, lycopene has been found to have a significant effect on the prevention and improvement of prostate diseases, and it is a gold product sought after by the health care product market at home and abroad. [0003] At present, there are many extraction methods of lycopene, but during the drying process of raw materials, lycopene will be oxidized and lost more, resulting in a low recovery rate of lycopene. For example, the publication number ...
