Problems solved by technology

For lycopene-containing extracts, the proportion of all-trans lycopene in commercially available lycopene extracts is generally more than 90%, although patents PCT / EP2007 / 006747, PCT / EP02 / 00708, US7126036, ZL201410736320.3, ZL201510021309.3, US9656250B2, etc. provide methods for converting all-trans lycopene into a cis configuration, but these patents involve isomerization of extracted lycopene, Its product is still lycopene extract, which cannot be directly consumed as food, and the amount and scope of its additives in food are restricted by GB2760

Embodiment 1

[0023] (1) select the yellow tomato with a solid content of 5.4% as raw material, and clean it after selection;

[0024] (2) Put the whole tomato into the container, inject high-heat steam with a gauge pressure of 0.8MPa, and wait for 30 minutes after the temperature and pressure in the container reach equilibrium;

[0025] (3) Using a casing heat exchanger, reduce the temperature of the system to 60°C with flowing water, beat the pulp, and separate the skin dregs and seeds;

[0026] (4) Pectinase hydrolysis: adjust the feed solution temperature to 55°C, system pH to 3.5, add 120mg / L pectinase (enzyme activity 30000U / g), and stir for 30 minutes;

[0027] (5) Vacuum concentration to a solid content of 34-38 Brix to obtain a fruit and vegetable sauce with a high proportion of cis-lycopene.

[0028] It is determined that the proportion of cis-configuration lycopene in the tomato paste to the total lycopene is 89.46%.

[0029] Table 1 shows the specific information of each peak....

Embodiment 2

[0033] (1) choose papaya with 7.0% soluble solids content as raw material, clean and remove the green skin after selection;

[0034] (2) Put the complete papaya with the green skin removed into the container, inject high-heat steam with a gauge pressure of 0.2 MPa, and keep it for 60 minutes after the temperature and pressure in the container reach equilibrium;

[0035] (3) Using a casing heat exchanger, the temperature of the system is lowered to 55° C. with flowing water, beating, and separating skin dregs and seeds;

[0036] (4) Pectinase hydrolysis: adjust the feed solution temperature to 40°C, system pH to 3.0, add 60mg / L pectinase (enzyme activity 20000U / g), and stir for 60 minutes;

[0037] (5) Filtrate the enzymolysis solution obtained in (4) to remove the supernatant, and dry and pulverize the residue to obtain fruit and vegetable powder with a high proportion of cis-lycopene.

[0038] It is determined that the proportion of cis-configuration lycopene in the fruit an...

Embodiment 3

[0040] (1) choose the wood turtle with a soluble solid content of 7.5%, and clean it up after selection;

[0041] (2) Put the whole wood turtle into the container, feed it with a gauge pressure of 0.6 MPa high-heat steam, and keep it for 45 minutes after the temperature and pressure in the container reach equilibrium;

[0042] (3) Using a casing heat exchanger, reduce the temperature of the system to 58° C. with flowing water, beat the pulp, and separate the skin dregs and seeds;

[0043] (4) Pectinase hydrolysis: adjust the feed solution temperature to 50°C, system pH to 3.0, add 80mg / L pectinase (enzyme activity 35000U / g), and stir for 45 minutes;

[0044] (5) Refining and homogenizing the enzymatic hydrolyzate obtained in (4), blending maltodextrin and other auxiliary materials, and spray drying to obtain a high-cis-lycopene proportion fruit and vegetable powder.

[0045] It is determined that the ratio of cis-configuration lycopene in the whole fruit and vegetable powder ...

Abstract

The invention discloses a fruit and vegetable product containing high-proportion cis configuration lycopene and a preparation method, and belongs to the technical field of functionalization of conventional foods. According to the fruit and vegetable product containing high-proportion cis configuration lycopene disclosed by the invention, raw materials having high solid matter content in fruits andvegetables of the same kind are preferably selected, through high-heat steam spraying and steaming with gauge pressure being 0.2-0.8MPa, after the temperature and pressure in a container are balanced, the balanced temperature pressure is continuously maintained for 30-60min, and then operations of performing enzymolysis, performing separation, performing concentration, performing drying and the like in processing of conventional fruit and vegetable paste, fruit and vegetable powder and fruit and vegetable whole powder are performed, so that the fruit and vegetable product containing high cisconfiguration lycopene content can be obtained. The achievement of the fruit and vegetable product disclosed by the invention has important effects on strengthening the functions of conventional fruitand vegetable product and has enormous market potential.

Description

technical field [0001] The invention relates to a fruit and vegetable product containing a high proportion of cis-configuration lycopene and a preparation method thereof, belonging to the technical field of traditional food functionalization. Background technique [0002] Lycopene is a kind of carotenoid, which contains 11 conjugated double bonds and two non-conjugated double bonds. It has various physiological functions such as anti-oxidation and enhancing immunity, especially its effect on reducing benign prostatic hyperplasia , has been recognized by many consumers. Under the steric hindrance effect of methylation, since the conjugated double bond in the molecule cannot rotate freely, lycopene has more spatial isomers, including all-trans, 5-cis, 7- Cis, 9-cis, 13-cis and 15-cis and other spatial configurations, usually we divide them into all-trans, cis (including 5-cis, 7-cis, 9- cis, 13-cis and 15-cis, etc.) two categories. The lycopene in natural food raw materials...
