Problems solved by technology

[0004] It is understood that the current lutein extracts all use intermittent saponification, and the saponification time in the saponification process is as long as 2-5 hours, which seriously affects the production capacity of lutein crystals. Under environmental conditions, the content loss is as high as 4-8%, which makes the yield of lutein crystals low and the product price high

Embodiment 1

[0026] Prepare 68.82kg of lutein extract with a lutein content of 16.023%, and keep it warm at 40°C. Prepare 37.28kg of potassium hydroxide solution with a mass concentration of 35.0%, and prepare an alcohol-alkali solution with 82.02L of 95% ethanol solution. First add 30.0kg of alcohol-alkali solution and 20.0kg of lutein extract into the saponification equipment, heat and keep warm at 60°C, and pre-saponify for 1.5 hours to obtain saponified lutein extract mixture I.

[0027] The saponification equipment has an effective saponification capacity of 20kg. Add lutein extract and alcohol-alkali solution to the saponified lutein extract mixture I at a rate of 16.27kg and 24.41kg per hour respectively, and feed continuously for 3 hours to achieve rapid and continuous saponification. It took 29.5 minutes to obtain lutein saponification solution.

Abstract

The invention discloses a continuous lutein extract saponifying process, and belongs to the technical field of natural plant extracts. The continuous lutein extract saponifying process comprises the following steps: adding a part of a lutein extract and a part of an alcoholic-alkaline solution into saponifying equipment, heating, mixing, and presaponifying to obtain a saponified lutein extract mixture I; continuously adding the lutein extract and the alcoholic-alkaline solution into the saponified lutein extract mixture I, heating, mixing, continuously feeding and continuously discharging at the same time to achieve rapid continuous saponification of the lutein extract so as to obtain saponified lutein liquid. In a way of continuous feeding, forcible mixing and circulating saponification, the rapid saponification of the lutein extract is achieved, the saponifying time is greatly shortened, the heated loss of the extract is reduced, and the final lutein crystal yield of a product is increased.

Description

technical field [0001] The invention belongs to the technical field of natural plant extracts, in particular to a continuous saponification process of lutein extract. [0002] technical background [0003] Lutein, also known as "plant lutein", is an oxygen-containing carotenoid widely found in natural plants such as marigold, banana, kiwi and corn. It is an antioxidant with excellent performance, which can resist the damage of cells and organs caused by oxygen free radicals in the human body, and prevent the symptoms of cardiovascular sclerosis and coronary heart disease caused by aging of the body. The most important thing is that lutein is the only carotenoid component that can exist in the lens of the eye. It is the main pigment and antioxidant component of the macula. Many eye diseases are closely related to the lack of lutein. It can be seen that lutein has a great effect on Eyes play an important protective role. [0004] It is understood that the current lutein extra...
