Embodiment 1

[0030] Fresh tomatoes are washed and chopped, put into a tissue crusher and crushed, filtered with a centrifuge to obtain tomato paste, and the impurity-removing agent sodium carbonate is prepared at 6 mol / L, which is twice the amount of tomato paste, and the obtained filter cake is filtered with a centrifuge , and then carry out the second level and the third level of impurity removal, the process is the same as above. The final obtained filter cake is dehydrated with 95% (volume) alcohol, and the amount is ten times that of the tomato filter cake. Filter the resulting filter cake with a centrifuge and then carry out the second stage of dehydration. The process is the same as above, and then add NY-70 solvent to the dehydrated filter cake Oil extraction, the amount is 6 times that of the filter cake for secondary cross-flow extraction, the extract is frozen and crystallized at -10°C for 20 hours, filtered to obtain lycopene crystals, and then vacuum-dried to obtain lycopene, l...

Embodiment 2

[0032] Except that the amount of the dehydrating agent added is eight times that of the tomato filter cake, the amount of the extractant NY-70 is eight times that of the filter cake, and the extract is cold crystallized at -20°C for 20 hours, other operations are the same as in Example 1 to obtain lycopene The crystal purity is 96.8%.

Embodiment 3

[0034] Wash the tomatoes, chop them, crush them in a tissue crusher, and filter them to obtain tomato paste; add 1mol / L sodium bicarbonate to the tomato paste to remove lipid impurities; wash the removed tomato paste with water, and add volume Concentration is 95% ethanol dehydration, the weight ratio of tomato sauce and ethanol is 1: 2, then add NY-90 solvent oil solvent and adopt primary extraction method to extract lycopene, make the tomato paste and NY-90 solvent oil solvent The weight ratio is 1:2; the extract is crystallized by intermittent natural cooling and crystallization, and the lycopene crystals are obtained after vacuum drying.

Abstract

The present invention relates to a lycopene extracting method, including: washing, chopping, crushing the tomato, adding 1-8mol / L of the impurity removal agent to remove lipid impurities, water washing, and then adding a dehydrating agent and dissolvant for extracting the lycopene, and then obtaining the lycopene crystal after crystallization and vacuum drying. Compared with the prior art, the invention has largely simplified process flow, without adopting the chromatographic fractionation and supercritical CO2 extraction, simple equipment, easy operation control, low production cost, and high lycopene crystal purity capable of reaching more than 96%. As reagent suitable for food industry applications is selected in the entire process flow, therefore, the product can be applied in food and pharmaceutical industries.

Description

technical field [0001] The invention relates to an extraction method, in particular to a lycopene extraction method. Background technique [0002] In "Food and Oils" 2004 No.8, the research progress of lycopene properties and extraction methods was disclosed, and the extraction methods were divided into direct crushing method, organic solvent leaching method, microwave method, supercritical CO 2 Extraction method, high performance liquid chromatography and organic matter preparation chromatographic analysis system extraction method, biological and chemical synthesis method, enzyme reaction method. The recommended extraction method of the organic matter preparation chromatographic analysis system, the separation purity can reach 80-90%, and the supercritical CO 2 The extraction method can obtain lycopene with a purity of more than 90%, and the purity of the product obtained by the organic solvent extraction method in the prior art is low. [0003] "Modern Food Science and T...
