Problems solved by technology

Lycopene is a conjugated polyene compound whose chemical properties determine that it has poor resistance to light, heat and oxygen damage. The differences in factors such as different drying processes, drying temperature, drying time and oxygen during the preparation of microcapsules , resulting in varying degrees of damage to lycopene
Vacuum freeze-drying is the most ideal process condition for lycopene microencapsulation, but the vacuum and low-temperature drying conditions required by t

Embodiment 1

[0013] Embodiment 1, the preparation method based on lycopene fat-soluble characteristic O / W type emulsion

[0014] The preparation method of the O / W type emulsion based on the fat-soluble properties of lycopene includes the preparation of the wall material solution, the preparation of the core material solution, the high-pressure homogenization and ultrasonic treatment after the core material solution and the wall material solution are mixed. After the optimized wall material and core material are formulated into a solution in proportion, the core material solution is slowly added to the wall material solution while stirring, and then placed in a high-pressure homogenizer to disperse lycopene evenly on the wall material solution. In the material, finally after ultrasonic treatment, a uniform and stable O / W emulsion is obtained.

Embodiment 2

[0021] Embodiment 2, microcapsule preparation method based on lycopene physicochemical properties

[0022] The preparation method of microcapsules based on the physical and chemical properties of lycopene includes several stages of spray drying of O / W emulsion, determination of solubility of lycopene microcapsules, and stability experiment. The orange-red lycopene microcapsules with high solubility and good light and heat stability are obtained after the O / W type emulsion prepared by the ultrasonic-assisted high-pressure homogenization method is spray-dried.

[0023] (1) Spray drying of O / W emulsion

[0024] The homogenized emulsion is spray-dried to obtain orange-red, powdery lycopene microcapsule products. The air inlet temperature of spray drying is controlled at 185°C, the outlet air temperature is controlled at 65-70°C, and the feed temperature is controlled at 50°C , the air inlet pressure is controlled at 0.15MPa, the feeding speed is 40-60 gears, and the blowing speed...

Abstract

The invention discloses a production method of lycopene microcapsule, providing a production method for realizing lycopene encapsulated emulsion by spray drying on the basis of the physical and chemical properties of lycopene. The method comprises the following steps: blending wall material solution, blending core material solution, homogenizing after the core material solution is mixed with the wall material solution, carrying out spray drying on emulsion, measuring lycopene microcapsule solubility, carrying out stability test and the like. Preferably, the preparation step of the lycopene microcapsule also comprises: an ultrasound assisted high-pressure homogenizing method is adopted to prepare the emulsion; and homogenized emulsion is performed with spray drying to obtain the lycopene microcapsule which has high solubility and favorable stability for light, heat and oxygen.

Description

technical field [0001] The invention relates to a production method of lycopene microcapsules, in particular to a production method based on the physical and chemical properties of lycopene and realizing microencapsulation of lycopene by spray drying. Background technique [0002] Lycopene is a fat-soluble natural pigment with the molecular formula C 40 h 56 , relative molecular mass is 536.85, and β-carotene are isomers. Lycopene is widely distributed in various plants. Tomatoes, watermelons, plums, persimmons, mango fruits, leaves of tea trees, turnips, and cabbage roots all contain lycopene, especially in tomatoes, which can reach 3- 14mg / 100g, and the higher the maturity, the higher the lycopene content. At present, the physiological functions of lycopene have been confirmed by more and more research results, and its antioxidant capacity is the strongest among carotenoids, which is twice that of lycopene and β-carotene, and is V E It also has anti-cancer and anti-can...
