Description
Technical Field
The invention relates to a method for stably immobilizing carotenoid pigments, in particular to a method for preparing a carotenoid stable product by using clay minerals, belonging to the technical field of natural pigment stabilization and immobilization.
Background
Carotenoids (carotenoids) are one of the main natural pigments of foods, and are widely found in various plants in nature, such as corn, medlar, tomato, orange, pepper, carrot, and the like. The carotenoid comprises alpha-carotene, beta-carotene, gamma-carotene, lycopene, zeaxanthin, lutein and the like, and has various biological activities of resisting oxidation, resisting tumors, improving the immune function of an organism and the like. Carotenoids are now recognized by international organizations such as FDA, european community, WHO as food additives and nutritional supplements. However, main carotenoids such as beta-carotene, lycopene and lutein are all fat-soluble substances, and have poor solubility in water, and the carotenoids have poor stability in oxygen, acid, strong light and high temperature, and are easy to degrade, change or isomerize, so that the development and application of the carotenoids are restricted; in addition, carotenoids in the form of coarse crystals of natural structure are difficult to absorb by the human body and have very low bioavailability.
The clay mineral is a non-metal mineral widely distributed in nature, is a silicate mineral mainly containing elements such as aluminum, magnesium and the like, and is widely applied to the fields of catalysts and adsorbents due to various excellent performances such as plasticity, adsorbability, dehydration rehydration and the like; and the clay mineral has large storage capacity, low price and no pollution to the environment, and is one of more ideal adsorbents. The clay mineral modified by acid method, alkali method, salt method or ion exchange method can improve surface activity and enhance adsorption capacity. At present, clay minerals which are researched more at home and abroad mainly comprise attapulgite, bentonite, diatomite, montmorillonite, kaolin and the like. However, no research on the preparation of clay mineral stabilized immobilized carotenoid pigment products is available.
