Abstract

The invention discloses fortified nutrition salt containing vitamin A microcapsules and a preparation method thereof. The nutrition salt is prepared from the vitamin A microcapsules and table salt A,wherein each vitamin A microcapsule is prepared by taking vitamin A oil as a core material, a mixture of gelatin, carboxymethyl cellulose and table salt B as a wall material and an emulsifier and a curing agent as auxiliary materials, wherein the mass ratio of the gelatin to the carboxymethyl cellulose to the table salt B in the wall material is (4.5 to 5.5) : (0.5 to 1.5) : (0.1 to 0.3). According to the fortified nutrition salt disclosed by the invention, a certain amount of the table salt is added into the wall material so that the mechanical property of the wall material is increased; thefortified nutrition salt contains the vitamin A microcapsules so that the mechanical strength resistance is relatively strong and the stability is high; oil-soluble liquid-state vitamin A is solidified in a microcapsule form so that the stability of the vitamin A is improved and the vitamin A is convenient to process and store.

Description

technical field [0001] The invention belongs to the field of food condiments, in particular to a vitamin A-containing fortified nutrient salt and a preparation method thereof. Background technique [0002] In recent years, people's dependence on electronic products has made excessive eye use a common social problem around the world. Looking at electronic screens for a long time will consume a lot of vitamin A. Eye diseases such as myopia, dry eye, conjunctivitis, and glaucoma are becoming more common and showing a younger age trend. Under the condition that the social environment cannot be changed, it is very important to supplement vitamin A reasonably to prevent night blindness and vision loss. [0003] Vitamin A, also known as retinol, is a fat-soluble alcohol substance and an important nutrient that constitutes the photosensitive substance of the retina. It cannot be synthesized by the body and must be ingested from the outside world. However, factors such as light, he...
