Problems solved by technology

Because dioxin and capsanthin are all oil-soluble substances, the current method for producing capsanthin ointment cannot effectively separate dioxins, so the dioxin content in the capsanthin feed additive produced by the prior art is very high, usually exceeding EU standards, but there is currently no effective method to reduce the content of dioxins in capsanthin feed additives

Embodiment 1

[0026] The preparation method of the capsanthin feed additive with low dioxin content is as follows:

[0027] 1) Take 250g of commercially available capsicum red ointment and dissolve it in 1L of absolute ethanol; take 75g of potassium hydroxide and dissolve it with a small amount of absolute ethanol; raise the temperature of the capsicum red ointment solution to 80°C, and add it dropwise while stirring Potassium hydroxide solution, then continue stirring reaction with the speed of 30rpm;

[0028] 2) After reacting for 2h, filter to obtain a solidified saponified product;

[0029] 3) Add saponified matter to 2.5L acetone, stir to make it fully dissolve, then filter to remove insoluble matter, distill the filtrate to recover acetone, and obtain 75.9g capsanthin ointment with low dioxin content;

[0030] 4) Take 200ml of ethanol, dissolve the above-mentioned capsanthin ointment, and then stir and mix with 800g of white carbon black to obtain a low-dioxin-content capsanthin feed...

Embodiment 2

[0033] The preparation method of the capsanthin feed additive with low dioxin content is as follows:

[0034] 1) Take 500g of commercially available capsicum red ointment and dissolve it in 1L of absolute ethanol; take 200g of potassium hydroxide and dissolve it with a small amount of absolute ethanol; raise the temperature of the capsicum red ointment solution to 60°C, and add it dropwise while stirring Potassium hydroxide solution, then continue stirring reaction with the speed of 40rpm;

[0035] 2) After reacting for 3h, filter to obtain a solidified saponified product;

[0036] 3) Add the saponified matter into 4L of acetone, stir to make it fully dissolve, then filter to remove the insoluble matter, distill the filtrate to recover the acetone, and obtain 151.5 g of capsicum ointment with low dioxin content;

[0037] 4) Take 300ml of ethanol, dissolve the above-mentioned capsanthin ointment, and then stir and mix with 2.2kg of calcium silicate to obtain a low-dioxin-conte...

Embodiment 3

[0040] The preparation method of the capsanthin feed additive with low dioxin content is as follows:

[0041] 1) Take 500g of commercially available capsicum red ointment and dissolve it in 1.5L of absolute ethanol; take 200g of potassium hydroxide and dissolve it with a small amount of absolute ethanol; raise the temperature of the capsicum red ointment solution to 70°C and, under stirring, drop Add potassium hydroxide solution, then continue stirring reaction with the speed of 50rpm;

[0042] 2) After reacting for 2.5h, filter to obtain a solidified saponified product;

[0043] 3) Add the saponified matter into 3L of acetone, stir to make it fully dissolve, then filter to remove the insoluble matter, distill the filtrate to reclaim the acetone, and obtain 154.5 g of capsicum ointment with low dioxin content;

[0044] 4) Take 300ml of ethanol, dissolve the above-mentioned capsanthin ointment, and then stir and mix with 2.3kg of bentonite to obtain a low-dioxin content capsan...

Abstract

The invention discloses a preparation method of a capsanthin feed additive with low dioxin content. According to the preparation method, commercially available capsanthin factice is further saponified, and then an acetone solvent is used for extracting, so that the dioxin content in the capsanthin factice is effectively reduced; and then the capsanthin factice and a feeding carrier are mixed uniformly, thus obtaining the capsanthin feed additive with low dioxin content. Therefore, the feeding safety of capsanthin can be improved. The preparation method fills up the research blank of the capsanthin feed additive with low dioxin content, is simple and effective and can adapt to demands of industrial production.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a preparation method of capsicum red feed additive with low dioxin content. Background technique [0002] Animals cannot synthesize pigments by themselves and must be ingested from feed. Therefore, colorants are often used in feed processing and breeding to improve the internal quality and external sensory properties of livestock products. The safety of livestock products caused by the use of a large number of synthetic colorants has plagued the development of the industry, while the application of natural colorants has the dual functions of general pigments and nutritional additives, which is of great significance to the safe and high-quality production of livestock products. Natural pigments are generally derived from animals and plants, such as sugar beets, grapes and peppers. Compared with synthetic pigments, natural pigments from food sources are safer and more favored by consu...
