The hydration agent was preheated to 50°C and added to the mixed solution A, stirred and kept at 55°C for 1 hour to obtain the mixed solution B.

[0024] Step 3: Preparation of diluent: Add 120Kg of glycerol and 120Kg of deionized water into the mixing tank, heat to 55°C, stir and keep warm for 10min, then naturally cool down to 30°C to obtain the diluent.

[0025] Step 4: Slowly add diluent preheated to 40°C to the mixture B obtained in step 2, keep warm at 60°C and stir for 10 minutes, then cool down naturally to 20°C to obtain a water-soluble lutein ester with a col...

Embodiment 2

[0031] Step 1: Add 60Kg of commercially available lutein ester (color value 400), 300Kg of soybean oil, and 1Kg of vitamin E into the mixing tank, heat and stir at 80°C for 20 minutes to obtain a uniform mixture A;

[0032] Step 2: Add Span8060Kg and Tween80120Kg into the mixing tank, heat to 60°C, stir and keep it warm for 10 minutes, then cool down naturally to 28°C to obtain the hydration agent. Preheat the hydration agent to 60°C and add it to the mixed solution A, stir and keep it warm at 60°C for 1 hour to obtain the mixed solution B;

[0033] Step 3: Preparation of diluent: Add 120Kg of sorbitol and 300Kg of deionized water into the mixing tank, heat to 60°C, stir and keep warm for 10min, then naturally cool down to 30°C to obtain the diluent;

[0034] Step 4: Slowly add diluent preheated to 60°C to the mixture B obtained in step 2, keep warm at 55°C and stir for 10 minutes, then cool down to 25°C naturally to obtain a water-soluble lutein ester with a color value of 24...

Embodiment 3

[0037] Step 1: Add 60 g of commercially available lutein ester (color value 450), 360 g of soybean oil, and 1.2 g of rosemary into the mixing tank, heat and stir at 75°C for 18 minutes to obtain a uniform mixture A;

[0038] Step 2: Add 100g of Span85 and 500g of Tween60 into the mixing tank, heat to 55°C, stir and keep warm for 10min, then cool down to 28°C naturally to obtain the hydration agent. Preheat the hydration agent to 65°C, add it into the mixed solution A obtained in step 1, stir and keep it warm at 65°C for 1 hour, and obtain the mixed solution B;

[0039] Step 3: Preparation of diluent: Add 400g of glycerol and 500g of deionized water into the mixing tank, heat to 65°C, stir and keep warm for 10min, then naturally cool down to 27°C to obtain the diluent;

[0040] Step 4: Slowly add diluent preheated to 65°C to the mixture B obtained in step 2, keep warm at 65°C and stir for 10 minutes, then naturally cool down to 25°C to obtain a water-soluble lutein ester with a...

Abstract

The invention relates to a method for manufacturing a water-soluble lutein ester, and belongs to the fields of natural food colorants and nutritional supplements. The invention particularly relates to a formula of modifying an oil-soluble lutein ester into the water-soluble lutein ester and a technology thereof. The method comprises the following steps: adding commercial lutein ester, vegetable oil and an antioxidant based on a weight ratio of 1:2-10:0.01-0.03 into a mixing cylinder; heating to 60-90 DEG C, and uniformly stirring and thermal insulating for 10-20 minutes to obtain a uniform mixed liquor A; while stirring, adding a hydrated agent which is preheated to 50-80 DEG C, and thermal insulating and stirring at the temperature of 55-65 DEG C for 1 hour to obtain a mixed liquor B; adding a diluter, which is preheated to 40-80 DEG C, into the mixed liquor B; and uniformly stirring at 55-65 DEG C, and naturally cooling to below 30 DEG C to obtain the stable water-soluble lutein ester. The invention has the advantages of simple technology, strong adaptability and easy large-scale industrial production. When being stored at room temperature or low temperature, the water-soluble lutein ester can not become turbid, does not precipitate floccule and has favorable flowing property.

Description

technical field [0001] The invention discloses a preparation method of water-soluble lutein ester, which belongs to the fields of natural food colorants and nutritional supplements. It specifically relates to a formula and technology for modifying lutein ester from oil-soluble to water-soluble. Background technique [0002] Lutein ester is a fat-soluble light red paste, which is extracted from the flowers of "Marigold", contains marigold red, vitamin B, vitamin C, carotene and other natural nutrients, and belongs to the active substances of the carotenoid family . It is a food coloring that is safe, reliable, non-toxic and harmless, and can improve human health. It can be widely used in meat products, fish products, various canned foods, beverages, fruit juices, pasta, cakes and advanced cosmetics (such as rouge, lipstick, etc.) , nail polish), etc., can also be used in medicine, feed and other fields. In recent decades, lutein esters have been continuously researched due...
