preparation example Construction

[0025] The preparation method of the oil phase: 5 g of lycopene was dissolved in 50 mL of ethyl acetate, stirred and dissolved at 60° C. to obtain the oil phase.

[0026] Preparation of microcapsules: Take 10mL of uniformly mixed oil phase and slowly add it to the water phase of the wall material, and fully stir it. Considering the heat sensitivity of lycopene, evaporate the excess lycopene in the mixture at low temperature by rotary evaporation. organic solvent, so as to obtain the emulsion with solid content in accordance with the design of this experiment, and then homogenize it through a tissue grinder (15000r / min, 3min).

[0027] Lycopene emulsion was prepared by controlling different homogeneous pressures. Homogeneous pressure helps the core material and wall material to be fully mixed to improve the embedding effect, but too high homogeneous pressure will also make the lycopene emulsion droplet smaller and the surface free energy of the system increase, resulting in an ...

Embodiment 1

[0040] Prepare the optimized wall material formula into a solution: add 6g of whey protein isolate and 12g of fructooligosaccharide in a ratio of 1:2, control the reaction system pH=9, react at 90°C for 2 hours, and mix 10mL evenly Slowly add the core material solution into the wall material solution, and fully stir, and use the rotary evaporation method to evaporate the excess organic solvent in the mixed solution at a low temperature of 35-40°C, and homogenize for 3 minutes under the condition of 15000r / min . The microcapsule emulsion homogenized by the tissue masher was homogenized twice under the homogenization pressure of 40MPa.

Embodiment 2

[0042] Prepare the optimized wall material formula into a solution: add 6g of whey protein isolate and 12g of xylooligosaccharide in a ratio of 1:2, control the pH of the reaction system to 10, react at 90°C for 3h, and mix 10mL The uniform core material solution is slowly added to the wall material solution, and fully stirred, and the excess organic solvent in the mixed solution is evaporated at a low temperature of 35-40°C by rotary evaporation, and homogenized under the condition of 15000r / min. 3min. The microcapsule emulsion homogenized by the tissue masher was homogenized twice under the homogenization pressure of 40MPa.

Abstract

The invention provides a preparation method of lycopene microcapsules. The preparation method includes: preparing a wall and a core; adopting whey protein isolate and low-energy sugar to prepare the wall through Maillard reaction; dissolving lycopene in ethyl acetate, and stirring at temperature of 55-65 DEG C for dissolving to obtain a core solution; subjecting the wall and the core to homogeneous emulsification, and preparing the lycopene microcapsules through a method of spray drying. Compared with other existing walls, the preparation method has the advantages that a glycosylated product can be directly taken as a novel emulsifier, so that adding of several other emulsifiers is not needed.

Description

technical field [0001] The invention belongs to the technical fields of food and medicine, and relates to a preparation method of novel lycopene microcapsules, in particular to a method for preparing microcapsule wall materials after reacting whey protein isolate with energy-free glycosylation. Background technique [0002] Lycopene is one of the main carotenoids in various tissues and plasma in the human body. It is mainly distributed in blood, adrenal gland, liver, testis, prostate, breast, ovary, uterus and digestive tract and other organs. Its molecular formula is C 40 h 56 , is an isomer of β-carotene. A large number of studies at home and abroad have shown that lycopene has the functions of quenching singlet oxygen, scavenging free radicals in the body, blocking the formation of nitrosamines, and inhibiting cell proliferation. At present, the United Nations Expert Committee on Food Additives has identified lycopene as a type A nutrient, and it has been widely used in...
