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

[0019] 1) Dissolve 250g of commercially available capsicum ointment in 5L of absolute ethanol, heat up to 80°C, add 1L of potassium hydroxide ethanol solution with a concentration of 50g / L under stirring, and then continue stirring at a speed of 10rpm;

[0020] 2) After reacting for 1.5h, filter to obtain a solidified saponified product;

[0021] 3) Add saponified matter into 5L of acetone, stir to make it fully dissolve, then filter to remove insoluble matter, distill the filtrate to remove acetone, and obtain capsanthin ointment with reduced dioxin content.

[0022] 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%.

[0023] At the same time, the color va...

Embodiment 2

[0025] 1) Dissolve 200g of commercially available capsicum ointment in 4L of absolute ethanol, heat up to 70°C, add 500mL of potassium hydroxide ethanol solution with a concentration of 200g / L under stirring, and then continue to stir at a speed of 20rpm;

[0026] 2) After reacting for 1 hour, cool to room temperature, centrifuge to remove ethanol, and obtain a solidified saponified product;

[0027] 3) Add the saponified matter into 3L of acetone, stir to make it fully dissolve, then centrifuge to remove the insoluble matter, distill the supernatant to remove the acetone, and obtain capsanthin ointment with reduced dioxin content.

[0028] 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 1.58ng / kg, and ...

Embodiment 3

[0031] 1) Dissolve 200g of commercially available capsicum red ointment in 4L of absolute ethanol, heat up to 60°C, and add 500mL of sodium hydroxide ethanol solution with a concentration of 120g / L under stirring, and then continue stirring at a speed of 20rpm;

[0032] 2) After reacting for 2 hours, cool to room temperature, centrifuge to remove ethanol, and obtain a solidified saponified product;

[0033] 3) Add the saponified product into 3L of ethyl acetate, stir to make it fully dissolved, then filter to remove the insoluble matter, distill the filtrate to remove acetone, and obtain capsanthin ointment with reduced dioxin content.

[0034] 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 1.45ng / kg, ...

Abstract

The invention discloses a method for reducing the content of dioxin in capsicum red ointment. The commercially available capsicum red ointment is subjected to saponification reaction and solvent extraction to effectively reduce the dioxin content in the capsicum red ointment product. At the same time, the content of capsanthin in the ointment basically remains unchanged, which improves the food safety. The inventive method is simple and effective, and can meet the needs of industrialized 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...
