Problems solved by technology

The preparation process of this method is complicated, and a large amount of organic solvents need to be used. When the organic solvent and the protective colloid aqueous solution are mixed and desolvated, the system is very prone to foaming, which is difficult to control in production. Although the amount of solvent is reduced compared with the method provided by CN1942106A, it will still cause Solvent residues of organic solvents in final products

Embodiment 1

[0040] Put 100g of lutein crystals, 11g of sucrose stearate, 2g of d-alpha tocopherol, 3g of glyceryl monolaurate, and 49g of gum arabic into 1000ml of water, heat up to 40°C, and stir until the crystals are dispersed and suspended uniformly to obtain leaf Lutein suspension; under the protection of nitrogen, the suspension is circularly ground with a sand mill for 120 minutes and homogenized, so that the crystal particles are crushed and suspended stably; the stable suspension of lutein crystals is passed through a pipeline heater, The temperature of the heater is 125±2°C, and the time is 25s, so that the suspended particles of the crystals are finer and an emulsion is formed. The particle size of the lutein crystals in the emulsion is 260nm (D50). After cooling the emulsion to 60°C, add 400g of gum arabic, Stir 100g of maltoligosaccharides until completely dissolved, spray-dry the obtained emulsion into a dry powder, and then further agglomerate and granulate to obtain a cold-...

Embodiment 2

[0042] Put 123g of β-carotene crystals, 10g of polysorbate 80, 6g of glyceryl monostearate, 96g of modified starch (Hi Cap100 provided by National Starch USA), 6gdl-α tocopherol in 2200ml of water, and heat up to 46°C , stirred until the crystals are uniformly dispersed and suspended to obtain a suspension of β-carotene; under the protection of nitrogen, the suspension was circularly ground with a ball mill for 120 minutes to homogenize, so that the crystal particles were crushed and suspended stably; the β-carotene was The stable suspension of crystals passes through the pipeline heater. The temperature of the heater is 113°C and the time is 43s to make the suspended particles of the crystals finer and form an emulsion. After 40°C, add 620g of modified starch and 70g of maltooligosaccharide and stir until completely dissolved. The resulting emulsion is spray-dried into a dry powder, and finally cold water dispersible β-carotene microcapsule powder is obtained, with a β-caroten...

Embodiment 3

[0044] Put 62g of lycopene crystals, 5g of polyglycerol fatty acid esters, 3g of monoglyceryl and distearic acid glycerides, 9g of mixed tocopherols, and 113g of modified starch (Hi Cap100 provided by National Starch USA) in 1900ml of water and heat up to 43°C , stirred until the crystals were uniformly dispersed and suspended to obtain a lycopene crystal suspension; under the protection of nitrogen, the suspension was circulated and ground with a sand mill for 120 minutes to homogenize, so that the crystal particles were crushed and suspended stably; the lycopene The stable suspension of lycopene passes through the pipeline heater, the temperature of the heater is 123°C, and the time is 35s, so that the suspended particles of the crystal are finer and an emulsion is formed. The particle size of the lycopene crystal in the emulsion is 380nm (D50), and the temperature of the emulsion is cooled to After 40°C, add 790g of modified starch and 170g of maltooligosaccharide and stir u...

Abstract

The invention provides a method for preparing cold water dispersing type carotenoid micro-capsule powder without using an organic solvent. The method concretely comprises the following steps: (a) enabling carotenoid crystal to suspend in a water solution containing antioxidant, protective colloid and at least one non-ionic emulsifier; (b) grinding and homogenizing the solution obtained in the step (a) under the nitrogen protection to enable crystal particles to be ground and stably suspend; (c) carrying out micronization on the suspended particles of the obtained solution by a heating device to form an emulsion; (d) dissolving the protective colloid into the emulsion obtained in the step (c), carrying out secondary embedding, dewatering and drying to obtain powder particles. The method can solubilize carotenoid without using the organic solvent or vegetable oil, thus solving the problems of residual solvent, low carrying capacity and the like caused by the existing solvent method and a high temperature melting method. In all the steps of the method, the organic solvent is not used, so that the method is environment-friendly in technology; the process of high-temperature treatment is not needed, so that trans isomer is not produced, and the method is high in carrying capacity and small in loss of active ingredients.

Description

technical field [0001] The invention relates to a method for preparing cold water dispersible carotenoid microcapsule powder without using an organic solvent, more specifically, the method prepares a cold water dispersible instant carotenoid microcapsule powder with stable active ingredients. And this process abandons the shortcomings of organic solvents or oil phase high-temperature melting methods, which is more conducive to food safety. Background technique [0002] Carotenoids are a general term for a class of important natural pigments, which are commonly found in animals, higher plants, fungi and algae. Carotenoids are isopentenoid polymers containing 40 carbons. Carotenoids constitute a group of colors from yellow to red. Except for a few carotenoids such as phytoene and phytoene, which are colorless, most carotenoids are yellow, orange or red. Their color changes with the number of conjugated double bonds, the more the number of conjugated double bonds, the more th...
