Problems solved by technology

Therefore, the existing process route makes the cis-trans isomerization of β-carotene uncontrollable and the solvent remains, which greatly reduces the bioavailability and safety of β-carotene; in addition, the presence of β-carotene in the final product It is in a non-setting state, and the product color is orange-yellow, which cannot meet the market's demand for stable natural red pigment

Embodiment 1

[0026] Take 50g of gum arabic, 2g of vitamin C, and 10g of maltodextrin in 1000ml of water, heat up to 50-60°C, stir until the materials are completely dissolved and form a water-soluble colloid; after the materials are completely dissolved, cool the materials to 30-32°C , put it aside. Take 5 g of β-carotene crystals (its all-trans content is 98.1%) and slowly add to the prepared water-soluble colloid, mix and homogenize online with a pipeline shearer, and control the shear rate within the range of 5000 to 6000 rpm. Obtain β-carotene suspension with uniform particle size. The β-carotene suspension is circularly ground by a nano-scale sand mill, and the grinding conditions are controlled at a pressure of 0.8-1.0MPa, a speed of 1500-2000rpm, and a temperature of 30-35°C until the particle size of the suspension reaches 100nm ~300nm to form a nanosuspension. The obtained nano-suspension was spray-dried and granulated into β-carotene microcapsule powder. The microcapsule powder...

Embodiment 2

[0028] Take 50g of modified starch, 7g of synthetic tocopherol, and 35g of syrup in 1000ml of water, heat up to 65-75°C, stir until the material is completely dissolved and form a water-soluble colloid; after the material is completely dissolved, cool the material to 35-40°C , put it aside. Take 17.5 g of β-carotene crystals (its all-trans content is 98.3%) and slowly add to the prepared water-soluble colloid, mix and homogenize online with a pipeline shearer, and control the shear rate within the range of 10,000 to 12,000 rpm , to obtain β-carotene suspension with uniform particle size. The β-carotene suspension is circularly ground by a nano-scale sand mill, and the grinding conditions are controlled at a pressure of 1.0-1.2MPa, a speed of 2000-2500rpm, and a temperature of 35-40°C until the particle size of the suspension reaches 100nm ~300nm to form a nanosuspension. The obtained nano-suspension was spray-dried and granulated into β-carotene microcapsule powder. The micr...

Embodiment 3

[0030]Take 50g of hydrolyzed soybean protein, 7g of mixed tocopherols, and 50g of maltooligosaccharide in 1000ml of water, heat up to 75-80°C, and stir until the materials are completely dissolved to form a water-soluble colloid; after the materials are completely dissolved, cool the materials to 40-80°C. 45°C, put it aside. Take 25.0 g of β-carotene crystals (its all-trans content is 98.6%) and slowly add to the prepared water-soluble colloid, mix and homogenize online with a pipeline shearer, and control the shear rate within the range of 20,000 to 25,000 rpm , to obtain β-carotene suspension with uniform particle size. The β-carotene suspension is circularly ground by a nano-scale sand mill, and the grinding conditions are controlled at a pressure of 1.2-1.5MPa, a speed of 2500-3000rpm, and a temperature of 40-45°C until the particle size of the suspension reaches 100nm ~300nm to form a nanosuspension. The obtained nano-suspension was spray-dried and granulated into β-car...

Abstract

The invention relates to a preparation method of a red-colored item beta-carotene preparation with high bioavailability. The preparation method comprises the following steps: firstly, heating a water-soluble wall material, an antioxidant and a filler to fully dissolve the water-soluble wall material, the antioxidant and the filler to form water-soluble colloid, shearing beta-carotene under a low-temperature condition to allow the beta-carotene to be efficiently, quickly and uniformly dispersed in the water-soluble colloid, and finally grinding the beta-carotene through a nano grinding machine.According to the method, no organic solvents are used in the whole steps, and thus the process is environmentally-friendly and is more favorable for food safety. Meanwhile, the method has no high-temperature processes, and no solvent residues remain, so that cis-trans isomerism of the beta-carotene is avoided, and the bioavailability and the safety of the beta-carotene are greatly improved. According to the method, a beta-carotene suspension is cyclically ground through the nano grinding machine so as to finally form nano suspension with a particle size of 100 to 300 nm, so that the beta-carotene is uniformly dispersed in the water-soluble wall material in the form of nano crystals, and the stability and the developing effect are obviously improved; the product is in fresh red; and safe and stable haematochrome is provided for the market.

Description

technical field [0001] The invention relates to the technical field of biochemical engineering, and more specifically, relates to a preparation method of a red beta-carotene preparation with high bioavailability. 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 the color shifts to red. So far, more than 700 natural carotenoids have been discovered, which can be divided into two categories according to their chemical structures, one is carotene (such as β-carotene, lycopene), and the other i...
