Problems solved by technology

The common defect of the above-mentioned preparation methods is: the general lycopene extract or its purified product is used as raw material in the preparation, without cis-transformation, the lycopene in the product is easy to settle, so the water-dispersible lycopene that can be suspended stably The target component content in the plain emulsion is too low (0.02% ~ 0.3%), resulting in high cost of use, difficult to use in actual production

Embodiment 1

[0020] According to the ratio of lycopene with high cis-isomer content: oil: emulsifier: co-emulsifier: water = 0.01~2:1~2:2~8:1~4:5~40 and the following steps to prepare the containing Lycopene microemulsion with high cis isomer content:

[0021] ①Add 250g of lycopene with a high cis-isomer content of 10% (the mass percentage of cis-structure lycopene to the weight of lycopene is 70mg / 100mg) into 500g soybean oil, and dissolve at 174°C Uniform;

[0022] ②Heat 800g of emulsifier mixture (Tween 20+n-butanol, mass ratio is 2:3) to 100°C, stir at 100 rpm for 3 minutes, then add it to the mixture in step ①, at 150 rpm Stir for 10 minutes until uniform;

[0023] ③Put the uniformly mixed material into 800g of water, stir at 200 rpm for 20 minutes, store at 4°C, and dilute before use.

[0024] The lycopene content in the finally obtained lycopene microemulsion preparation with high content of cis-isomer was 1.06%.

Embodiment 2

[0026] According to the ratio of lycopene with high cis-isomer content: oil: emulsifier: co-emulsifier: water = 0.01~2:1~2:2~8:1~4:5~40 and the following steps to prepare the containing Lycopene microemulsion with high cis isomer content:

[0027] ①Add 170g of 30% lycopene with high cis-isomer content (the mass percentage of cis-structure lycopene to the weight of lycopene is 50mg / 100mg) into 310g of rapeseed oil and dissolve at 174°C Uniform;

[0028] ②Heat 550g of emulsifier mixture (sucrose laurate + isopropanol, mass ratio: 1:2) to 100°C, stir at a speed of 150 rpm for 5 minutes, then add to the mixture in step ①, Stir for 15 minutes at a speed of 100 rpm until uniform;

[0029] ③Slowly add the uniformly mixed material into 1400g of water, stir at 200 rpm for 20 minutes until uniform, store at 15°C, and dilute before use.

[0030] The lycopene content in the finally obtained lycopene microemulsion preparation with high content of cis-isomer was 2.1%.

Embodiment 3

[0032]According to the ratio of lycopene with high cis-isomer content: oil: emulsifier: co-emulsifier: water = 0.01~2:1~2:2~8:1~4:5~40 and the following steps to prepare the containing Lycopene microemulsion with high cis isomer content:

[0033] ①Add 140g of lycopene with a high cis-isomer content of 45% (the mass percentage of cis-structure lycopene accounting for lycopene weight is 30mg / 100mg) in 250g of ethyl oleate, at 174°C dissolve evenly;

[0034] ②Heat 600g of emulsifier mixture (Span 60+1,3-propylene glycol, mass ratio 1:1) to 100°C, stir at 100 rpm for 12 minutes until uniform, then add 1570g of water, Stir at 180 rpm for 10 minutes until uniform;

[0035] ③Mix the surfactant / co-surfactant / water mixture obtained in step ② with the oil suspension obtained in step ①, and stir at a speed of 200 rpm for 18 minutes until uniform. The resulting microemulsion was stored at 25°C until diluted for use.

[0036] The lycopene content in the finally obtained lycopene microe...

Abstract

The invention discloses a lycopene microemulsion preparation product with high cis-isomer content and a preparation method thereof. The lycopene microemulsion preparation product with high cis-isomer content is prepared by performing microemulsion treatment on lycopene which has high cis-isomer content and serves as a main active ingredient, an edible surfactant, a cosurfactant, edible oil and water, wherein the product is a red transparent or semitransparent emulsion product with droplet diameter of between 5 and 50nm; and the lycopene accounts for 1 to 3 mass percent of the product. The product can be used as a food antioxidant and a coloring agent and belongs to the technical field of production of functional food ingredients.

Description

technical field [0001] A lycopene microemulsion product with high cis-isomer content and a preparation method thereof. The present invention uses lycopene with high cis-isomer content as the main functional ingredient, and the microemulsification treatment with edible surfactants, co-surfactants, edible oils and water to produce droplets with a diameter of 5 The red transparent or translucent emulsion product of ~50nm is mainly used as food antioxidant and coloring agent, and belongs to the technical field of functional food ingredient production. Background technique [0002] Lycopene is a linear hydrocarbon compound composed of eleven conjugated double bonds and two non-conjugated double bonds, and is an intermediate in the biosynthesis of various carotenoids. Since the lycopene molecule contains a lot of conjugated double bonds, it has strong rigidity and the molecule cannot rotate internally, so lycopene has many stereoisomers, the more common ones include all-trans (al...
