Problems solved by technology

[0003] Because both dioxin and capsanthin are oil-soluble substances, the current method for producing capsanthin ointment cannot effectively separate dioxins, so the dioxin content in the capsanthin ointment produced by the prior art is very high, usually exceeding EU standards, and there is no effective method to reduce the content of dioxins in capsicum ointment

Embodiment 1

[0020] 1) Dissolve 250g of commercially available capsicum ointment in 5L of absolute ethanol, heat up to 80°C, and add 1L of potassium hydroxide ethanol solution with a concentration of 50g / L under stirring, and then continue stirring at a speed of 10rpm;

[0021] 2) After reacting for 1.5h, filter to obtain a solidified saponified product;

[0022] 3) Add the saponified product into 5L of acetone, stir to make it fully dissolved, then filter to remove the insoluble matter, distill the filtrate to remove the acetone, and obtain capsanthin ointment with reduced dioxin content.

[0023] The dioxins contained in the above samples were quantitatively analyzed by high-resolution gas chromatography-high-resolution mass spectrometry (HRGC-HRMS), and the detection result was: the content of dioxins in the initial capsicum red ointment was 3.32ng / kg , the content of dioxin in chili red ointment after treatment was 1.55ng / kg, and its content was reduced by 53.3%.

[0024] At the same ...

Embodiment 2

[0026] 1) Take 200g of commercially available capsicum red ointment and dissolve it in 4L of absolute ethanol, raise the temperature to 70°C, add 500mL of potassium hydroxide ethanol solution with a concentration of 200g / L under stirring, and then continue to stir and react at a speed of 20rpm;

[0027] 2) After reacting for 1 hour, cool to room temperature, centrifuge to remove ethanol, and obtain a solidified saponified product;

[0028] 3) Add the saponified product into 3L of acetone, stir to dissolve it fully, then centrifuge to remove the insoluble matter, distill the supernatant to remove the acetone, and obtain capsanthin ointment with reduced dioxin content.

[0029] The dioxins contained in the above samples were quantitatively analyzed by high-resolution gas chromatography-high-resolution mass spectrometry (HRGC-HRMS), and the detection result was: the content of dioxins in the initial capsicum red ointment was 3.32ng / kg , the content of dioxin in chili red ointment...

Embodiment 3

[0032] 1) Take 200g of commercially available capsicum red ointment and dissolve it in 4L of absolute ethanol, raise the temperature to 60°C, add 500mL of sodium hydroxide ethanol solution with a concentration of 120g / L under stirring, and then continue to stir and react at a speed of 20rpm;

[0033] 2) After reacting for 2 hours, cool to room temperature, centrifuge to remove ethanol, and obtain a solidified saponified product;

[0034] 3) Add the saponified product into 3L of ethyl acetate, stir to make it fully dissolve, then filter to remove the insoluble matter, distill the filtrate to remove acetone, and obtain capsanthin ointment with reduced dioxin content.

[0035] The dioxins contained in the above samples were quantitatively analyzed by high-resolution gas chromatography-high-resolution mass spectrometry (HRGC-HRMS), and the detection result was: the content of dioxins in the initial capsicum red ointment was 3.32ng / kg , the content of dioxin in chili red ointment a...

Abstract

The invention discloses a method for reducing the content of dioxin in capsanthin ointment. According to the method, the saponification and the solvent extraction are carried out on the commercially available capsanthin ointment to ensure that the dioxin content in capsanthin ointment products is effectively reduced and the content of capsanthin in the ointment basically remains unchanged at the same time, and therefore, the food safety is increased. The method disclosed by the invention is simple and effective and can be adapted to the requirements of industrial production.

Description

technical field [0001] The invention belongs to the field of food additives, in particular to a method for reducing the content of dioxin in capsicum red ointment. Background technique [0002] Capsicum red ointment is a dark red ointment-like substance obtained by crushing dried red peppers and extracting them with organic solvents. Its main component is capsanthin (a natural green and healthy carotenoid red pigment), which is widely used In industries closely related to human health, such as food processing, medicine and cosmetics. Commercially available capsicum red ointment is an ester mixture of capsanthin monomer and fatty acid. It has a spicy taste, is insoluble in water, and is easily soluble in vegetable oil and ethanol. And good heat resistance, acid and alkali resistance, oxidation resistance. Capsanthin is an edible red pigment that can be used according to the national standard GB2760-86. It can be used in canned food, pastry, oily food, sauce, processed aquat...
