specific Embodiment approach 1

[0027] Specific embodiment one: a kind of preparation method of micronano zeaxanthin is realized through the following steps:

[0028] （ 1 ) Raw material screening and pretreatment

[0029] Take a certain amount of corn yellow powder, crushed to 60~80 mesh, add water to adjust the moisture to 15~20% , balanced moisture 20~24h ；

[0030] （ 2 ) extrusion puffing treatment

[0031] Put the pretreated raw materials into the twin-screw extrusion extruder, at the extrusion barrel temperature 130~170 °C, screw speed 150~250r / min Under certain conditions, slowly and evenly add corn yellow powder to carry out extrusion puffing. Then after crushing by the pulverizer, the 60 Mesh sieve, obtain the corn yellow powder after pretreatment;

[0032] （ 3 ) corn yellow pigment extraction

[0033] Ultrasonic method is adopted, that is, the above-mentioned pulverized raw materials are weighed, and 10~20 times the volume of ethanol solution mixed at ultr...

specific Embodiment approach 2

[0036] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one lies in the steps ( 1 ) by adding water to adjust the moisture to 18% . Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0037] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one lies in the steps ( 2 ) Extrusion cylinder temperature 140~160 °C, screw speed 160~200r / min.

Abstract

The invention provides a preparation method of a micro-nano-corn yellow pigment and relates to a new method for micro-nanonization of a natural corn yellow pigment. By adopting the method, the problem that the natural corn yellow pigment has difficulty in being widely applied due to instability, easiness in decomposition, poor solubility and difficulty in absorption. The preparation method of the micro-nano-corn yellow pigment provided by the invention is performed according to the following steps: 1) performing pretreatment on raw material; 2) performing extrusion and popping treatment; 3) performing separation and extraction on the corn yellow pigment; and 4) preparing the micro-nano corn yellow pigment. The micro-nano corn yellow pigment provided by the invention has the following advantages: 1) high nutritional value and good in-vivo absorption and utilization effect; 2) small particle size, high solubility and good stability; 3) direct eating and no toxic or side effects; 4) high yield of the pigment and relatively low cost; and 5) relatively high actual application value and market prospects. The micro-nano corn yellow pigment has high nutritional value and can realize a physiological function in in-vivo full absorption and utilization.

Description

technical field [0001] The invention relates to a preparation method of micronano zeaxanthin. Background technique [0002] Natural pigments have been widely concerned due to their safety and important physiological functions to the human body. Zeaxanthin belongs to natural carotenoids, based on β-carotene, zeaxanthin (3 ， 3 ’ - Dihydroxy - β-carotene ) Cryptoxanthin (3- hydroxyl - β-carotene ) , Lutein as the main component of the mixture of carotenoids. [0003] These natural pigments are important carotenoids in the human body, widely distributed in multiple tissues of the human body, and play an important role in maintaining health. For example, it has the effect of efficiently annihilating linear oxygen and scavenging free radicals, which can protect the human body from damage caused by single oxygen and free radicals; lutein and zeaxanthin can protect the skin, Protects the retina and multiple tissues in the body from oxidative damage and p...
