Production method of lycopene microcapsule

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...

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 this method are relatively harsh, and the energy consumption required to remove the same quality of water is the highest, and the equipment is expensive, and the product cost is very high , while freeze-dried lycopene microcapsule products are easy to absorb moisture and oxygen

Although the quality of vacuum-dried lycopene microcapsules is good, special vacuum equipment is still required, and the operation process is cumbersome, making it difficult to achieve continuous industrial production
