Embodiment 1

[0020] Example 1, take by weighing 600g of lutein extract and 10g of 6% vitamin C aqueous solution, add in a 5000ml round bottom flask, dissolve 138g of analytical grade KOH in 600g of 95% ethanol, then dissolve the KOH under the condition of stirring Add the ethanol solution in the round bottom flask, after saponification reaction at 60°C for 3h, add 600g of distilled water at 60°C to dilute, then reclaim the alcohol in a vacuum environment with a pressure of -0.08Mpa and a temperature of 60°C to obtain 91% (volume to 389g of alcohol, and finally add 3000ml of 0.2mol / l hydrochloric acid aqueous solution at 60°C, stir for 60min, keep warm for 2h, centrifuge and separate the lutein crystals, wash the crystals with distilled water, and dry them at -0.095Mpa, at a drying temperature of 30 Under the condition of ℃, the crystal was dried in vacuum for 24h. 72.2 g of lutein crystals with a content of 885 g / kg were obtained. Mix 72.2 g of the above lutein crystals with 155 g of cycl...

Embodiment 2

[0021] Example 2, claim 42kg lutein extract and 0.7kg of 6% vitamin C aqueous solution, add in the reaction kettle of 200l, dissolve 9.66kg of analytical grade KOH in 42kg95% alcohol, then dissolve the KOH under the situation of stirring Add the ethanol solution in the reaction kettle, saponify at 65°C for 3h, add 42kg of distilled water at 60°C, and then recover the alcohol in a vacuum environment with a pressure of -0.085Mpa and a temperature of 50°C to obtain 91% (volume ratio) alcohol 24kg, press the saponified product into a 600l reaction kettle, add 210l of 0.2mol / l hydrochloric acid aqueous solution at 70°C, stir for 60min, keep it warm for 2h, centrifuge and separate the lutein crystals, wash the crystals with distilled water, and dry them in vacuum. Under the conditions of -0.098Mpa and a drying temperature of 40°C, the crystals were vacuum-dried for 24h. The obtained content is 880g / kg lutein crystal 5.10kg. Take 5.10 kg of the above lutein crystals and 15.30 kg of ...

Embodiment 3

[0022] Example 3, take by weighing 60kg of lutein extract and 1kg of 6% vitamin C aqueous solution, add in a 200l reaction kettle, dissolve 13.8kg of analytical grade KOH in 60kg of 95% alcohol, and then dissolve the KOH under the condition of stirring The ethanol solution is added in the reaction kettle, after saponification reaction at 70°C for 3h, add 60kg of distilled water at 60°C to dilute, and then the alcohol is reclaimed under a vacuum environment with a pressure of -0.09Mpa and a temperature of 55°C to obtain 91% (volume ratio ) of alcohol 38.9kg, press the saponified product into an 800l reaction kettle, add 300l of 0.2mol / l hydrochloric acid aqueous solution at 60°C, stir for 60min, keep it warm for 2h, centrifuge to separate the lutein crystals, and wash the crystals with distilled water , under the conditions of -0.1Mpa and drying temperature of 35°C, the crystal was vacuum-dried for 24h. 7.22 kg of lutein crystals with a content of 887 g / kg were obtained. Take ...

Abstract

A process for preparing the xanthophyll powder as a food additive from xanthophylls resin includes such steps as heating and stirring while dripping the aqueous solution of low-class alcohol, saponification while adding anti-oxidizing agent, filtering to obtain xanthophylls crystals, washing with de-ionized water, vacuum drying and pulverizing. It has high stability.

Description

technical field [0001] The patent of the present invention relates to a method for preparing a non-odor food additive lutein powder from lutein resin. Background technique [0002] Lutein is a large class of carotenoids, which are natural pigments widely present in vegetables, flowers, fruits and some algal organisms. As early as the 1980s, Western researchers discovered that natural lutein contained in plants It is an excellent antioxidant. Adding a certain amount of lutein to food can prevent a series of diseases caused by organ aging. Foreign studies have confirmed that lutein can prevent macular degeneration of the eyeball caused by aging. Vision loss and blindness can prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by body aging. The United States "Food and Drug Administration" has approved lutein as a food supplement for food and beverage as early as 1995. In recent years, my country has also begun to apply it in the food and pharma...
