Embodiment 1

[0037] Preparation process of water-soluble lutein ester:

[0038] Heat the oil-soluble lutein ester to 65°C, then add polyglycerol fatty acid ester and tert-butyl hydroquinone, and place the mixture in a mixer at a speed of 200 rpm for 2 hours to make the mixture Mix well. Based on the weight of the oil-soluble lutein ester, the amount of polyglycerin fatty acid ester is 2%, and the amount of tert-butyl hydroquinone is 0.5%. Use a high-speed shear homogenizer to homogenize the mixed mixture at a speed of 2500 rpm for 35 minutes to obtain a lutein ester emulsion, which is vacuum-dried at 55° C., pulverized, and passed through a 100-mesh sieve. Water-soluble lutein ester powder is obtained.

[0039] The process of preparing hard candy using the water-soluble lutein ester obtained above:

[0040] Prepare the following raw materials in terms of mass percentage: 75% of sugar substances, 0.1% of water-soluble lutein ester powder, 2% of apple juice concentrate, 1% of gelling agen...

Embodiment 2

[0043] Preparation process of water-soluble lutein ester:

[0044] Heat the oil-soluble lutein ester to 45°C, then add triglyceryl monostearate, polyglyceryl ricinoleate, butylhydroxyanisole and dibutylhydroxytoluene to it, and place the mixture in a blender Thoroughly stir at 300 rpm for 3 hours to fully mix the mixture. Based on the weight of oil-soluble lutein esters, the total amount of both the tripolyglycerol monostearate and the polyglycerol ricinoleate is 5%, and the butyl hydroxyanisole and dibutyl hydroxytoluene The total dosage is 0.3%. Use a high-speed shear homogenizer to homogenize the mixed mixture at a speed of 3500 rpm for 20 minutes to obtain a lutein ester emulsion, which is vacuum-dried at 55° C., pulverized, and passed through a 100-mesh sieve. Water-soluble lutein ester powder is obtained.

[0046] Prepare the following raw materials in terms of mass perc...

Embodiment 3

[0049] Preparation process of water-soluble lutein ester:

[0050] Heat the oil-soluble lutein ester to 50°C, then add diacetyl tartrate mono-diglyceride, polyethylene glycol 300, polyethylene glycol 400, propyl gallate and vitamin E, and place the mixture in a blender Stir well at 400 rpm for 1.5 hours to fully mix the mixture. Based on the weight of oil-soluble lutein esters, the total amount of the three diacetyl tartrate mono-diglycerides, polyethylene glycol 300 and polyethylene glycol 400 is 8%, and the propyl gallate and vitamin E The total dosage is 0.8%. Use a high-speed shear homogenizer to homogenize the mixed mixture at a speed of 3000 rpm for 25 minutes to obtain a lutein ester emulsion, which is vacuum-dried at 55°C and then pulverized, passed through a 100-mesh sieve, Water-soluble lutein ester powder is obtained.

Abstract

The invention discloses a preparation method of water-soluble lutein ester. The preparation method comprises the steps of sufficiently and uniformly mixing oil-soluble lutein ester with an emulsifying agent and an antioxidant so as to obtain a mixture, and carrying out vacuum drying on the mixture, wherein the emulsifying agent consists of one to three of molecular distillation monoglyceride, polyglycerol fatty ester, tripolyglycerol monostearate, polyglycerol polyricinoleate, diacetyl tartaric acid mono / di-glyceride, polyethylene glycol 300, polyethylene glycol 400 and polyethylene glycol 600. According to the preparation method, the molecular distillation monoglyceride, the polyglycerol fatty ester and the like serve as the emulsifying agent, so that good emulsifying effect can be achieved, and the water-soluble lutein ester with high quality is obtained finally. The invention further provides the water-soluble lutein ester obtained through the preparation method and hard candy containing the water-soluble lutein ester.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for emulsification modification of oil-soluble lutein ester and hard candy containing the water-soluble lutein ester prepared according to the method. Background technique [0002] Hard candy is the oldest item in China's confectionary industry, accounting for about 22% of the confectionery market. It is deeply loved by consumers as a daily snack food. With the gradual improvement of people's health care awareness, higher requirements have been put forward for the health and health preservation of food. [0003] Lutein ester is an important fatty acid ester of carotenoids, widely present in marigold flowers, pumpkin, cabbage, alfalfa and other plants. Current research shows that lutein esters have extensive and effective physiological functions. 1. Lutein ester can protect eyes from light damage, delay eye aging and prevent disease, especially effective in preventing AMD...
