Embodiment 1

[0059] An iron-supplementing anthocyanin blue pigment is a combination of ferrous anthocyanin complex and xanthan gum. The molar ratio of anthocyanin to ferrous ion in the ferrous anthocyanin complex is 1:10, and anthocyanin and yellow The mass ratio of raw gum is 1:10.

[0060] The preparation method is as follows:

[0061] (1) Extraction of anthocyanins: Weigh 30 g of crushed purple eggplant skin, add an acidic ethanol solution (250 mL, pH value 2.0) with an ethanol concentration of 60%, and use ultrasonic extraction method to extract in the dark at 30 ° C for 30 min. After centrifuging at 5000r / min for 20min, the supernatant was collected, and the filter residue was extracted twice as above, and the supernatant was combined, concentrated by rotary evaporation at 40°C to obtain the crude extract of purple eggplant skin anthocyanins; the crude extraction of purple eggplant skin anthocyanins The solution was extracted with ethyl acetate to remove flavonoids, and then purified...

[0065] An iron-supplementing anthocyanin blue pigment, which is a combination of ferrous anthocyanin complex and sodium alginate, the molar ratio of anthocyanin and ferrous ion in the ferrous anthocyanin complex is 1:15, anthocyanin and seaweed The mass ratio of sodium bicarbonate is 1:25.

[0066] The preparation method is as follows:

[0067](1) Extraction of anthocyanins: Weigh 30 g of crushed triticale bran, add an acidic ethanol solution (300 mL, pH 2.0) with an ethanol concentration of 60%, and extract in the dark at 30°C for 30 min by ultrasonic extraction , after centrifuging at 4500r / min for 20min, the supernatant was collected, and the filter residue was repeatedly extracted twice as above, and the supernatant was combined, concentrated by rotary evaporation at 40°C to obtain the crude extract of triticale bran anthocyanins; the triticale bran flower color The crude glycoside extract was extracted with ethyl acetate to remove flavonoids, and then purified using macr...

Embodiment 3

[0071] An iron-supplementing anthocyanin blue pigment, which is a combination of ferrous anthocyanin complex and xanthan gum, the molar ratio of anthocyanin and ferrous ion in the ferrous anthocyanin complex is 1:20, anthocyanin and yellow The mass ratio of raw gum is 1:0.1.

[0072] The preparation method is as follows:

[0073] (1) Extraction of anthocyanins: Weigh 30 g of ground wolfberry slag, add acidic ethanol solution (300 mL, pH 2.0) with ethanol concentration of 70%, and use ultrasonic extraction method to extract in the dark at 30 ° C for 40 min , after centrifuging at 5500r / min for 20min, the supernatant was collected, and the filter residue was repeatedly extracted twice as above, and the supernatant was combined, concentrated by rotary evaporation at 40°C to obtain the crude extract of Lycium barbarum anthocyanins; crude Lycium barbarum anthocyanins The extract was extracted with ethyl acetate to remove flavonoids, and then purified using the macroporous resin XA...

Abstract

The invention provides an iron-supplementing anthocyanin blue pigment and a preparation method and application thereof. The iron-supplementing anthocyanin blue pigment comprises a combination of an anthocyanin ferrous complex and polysaccharide. On one hand, the iron-supplementing anthocyanin blue pigment is used as a functional blue pigment, has the characteristics of safety, health, high stability and controllable color, and shows different degrees of blues, such as bluish violet, sky blue, light blue or dark blue, in a pH value range of 3.6-6.6, so that the problems of scarcity of an edibleblue pigment and worry of people on the safety of artificial synthetic pigments are solved; and on the other hand, the iron-supplementing anthocyanin blue pigment has an excellent health-care function, can exert the effects of supplementing iron, resisting oxygenated free radicals and resisting intestinal inflammation, has no iron smell as a novel iron supplement agent, has the characteristics ofbeing easy to absorb and protecting gastrointestinal health, and effectively overcomes the defects of iron smell and gastrointestinal irritation of a traditional iron supplement agent.

Description

technical field [0001] The invention belongs to the technical field of functional pigments, and in particular relates to an iron-supplementing anthocyanin blue pigment and a preparation method and application thereof. Background technique [0002] Synthetic pigments are often used in the food industry, but some synthetic pigments have been proven to have harmful effects on human health; research results in recent years have shown that azo dyes are closely related to attention deficit hyperactivity disorder (ADHD) in children. With the improvement of people's health awareness, it has become an important goal of the food industry to replace artificial pigments with natural pigments. Among the natural food pigments, red and yellow pigments are rich in resources, such as red rice red, beet red, capsicum red, monascus red, turmeric, gardenia yellow and carotene. In contrast, natural blue pigment resources are very scarce, and there are only three kinds of gardenia blue pigment, ...
