Embodiment 1

[0030] A method for extracting gardenia pigment by steam explosion, comprising the following steps,

[0031] (1) Firstly, put gardenia jasminoides into the steam explosion device, pass saturated steam inward, keep the steam pressure at 3MPa, open the exhaust valve after 2 minutes, release the pressure in the device instantly, and obtain steam explosion gardenia jasminoides.

[0032] (2) Add 70% ethanol to steam-exploded gardenia and extract under reflux for 20 minutes, filter, and repeat the extraction once again. The combined filtrate is recovered with ethanol, the remaining liquid after recovery is concentrated, and spray-dried to obtain dry powder of gardenia pigment.

[0033] The application method of the gardenia pigment extracted by steam explosion in poultry breeding, the gardenia pigment dry powder is used as a feed additive, and is added to the diet of laying poultry at a ratio of 0.05% to 0.1% by weight.

Embodiment 2

[0035] A method for extracting gardenia pigment by steam explosion, comprising the following steps,

[0036] (1) Firstly, put gardenia jasminoides into the steam explosion device, pass saturated steam inward, maintain the steam pressure at 7MPa, and open the exhaust valve for 4 minutes, so that the pressure in the device is released instantly, and steam-exploded gardenia jasmine is obtained.

[0037] (2) Add 75% ethanol to steam-exploded gardenia and extract under reflux for 20 minutes, filter, and repeat the extraction once again. The combined filtrate recovers ethanol, the recovered remaining liquid is concentrated, and spray-dried to obtain gardenia pigment dry powder.

[0038] The application method of the gardenia pigment extracted by steam explosion in poultry breeding, the gardenia pigment dry powder is used as a feed additive, and is added to the diet of laying poultry at a ratio of 0.05% to 0.1% by weight.

Embodiment 3

[0040] A method for extracting gardenia pigment by steam explosion, comprising the following steps,

[0041] (1) Firstly, put gardenia jasminoides into the steam explosion device, pass saturated steam inward, keep the steam pressure at 10MPa, open the exhaust valve after 6 minutes, release the pressure in the device instantly, and obtain steam explosion gardenia jasminoides.

[0042] (2) Add 80% ethanol to the steam-exploded gardenia and extract under reflux for 30 minutes, filter, and repeat the extraction once again. The combined filtrate is recovered with ethanol, the remaining liquid after recovery is concentrated, and spray-dried to obtain dry powder of gardenia pigment.

[0043]The application method of the gardenia pigment extracted by steam explosion in poultry breeding, the gardenia pigment dry powder is used as a feed additive, and is added to the diet of laying poultry at a ratio of 0.05% to 0.1% by weight.

Abstract

The invention provides a method for extracting gardenia pigment by steam explosion and application of the extracted pigment. The extraction method is simpler and does not affect poultry use. A method for extracting gardenia pigment by steam explosion, comprising the following steps: (1) performing steam explosion treatment on gardenia; (2) adding ethanol to the gardenia after steam explosion for reflux extraction, filtering, recovering ethanol from the filtrate, and recovering the remaining The solution was concentrated and spray-dried to obtain gardenia pigment dry powder. As an egg and poultry feed additive, the gardenia pigment prepared based on the steam explosion technology mainly plays a coloring role, deepens the color of poultry egg yolk, and satisfies consumers' requirements for egg quality to a great extent. As a feed additive to directly feed laying poultry, subsequent cumbersome refining steps can be omitted, thereby expanding the application field of gardenia pigment.

Description

technical field [0001] The invention belongs to the field of preparation methods and applications of natural pigments, and in particular relates to a method for extracting gardenia pigments by steam explosion and an application method of the extracted pigments. Background technique [0002] Natural pigment is a kind of coloring agent in food additives. Most natural pigments are biologically active and have the function of nutritional enhancement. For example, carotene is listed as a nutritional additive in foreign countries, and the United States has applied carotene to infant food; some have pharmacological effects such as prevention and treatment of certain human diseases and health care functions, such as anthocyanins have anti-inflammatory, anti-tumor The function of scavenging oxygen free radicals, inhibiting lipoprotein oxidation and platelet aggregation. The research, development and application of natural food coloring are developing very rapidly, which is a new tre...
