Abstract

The invention discloses a method for preparing oil-soluble and fat-soluble caramel pigments with edible safety. The method comprises the following steps: firstly, filling caramel pigment raw materials into an extraction kettle of a supercritical fluid extracting device; then, performing the supercritical CO2 fluid extraction on the caramel pigment raw materials under the following extraction conditions that: the extraction kettle pressure is between 10 and 40 MPa, the pressure of a separation kettle I is between 5 and20 MPa, the pressure of a separation kettle II is between 3 and 15 MPa, the extraction time is 10 to 90 min, the temperature of the extraction kettle is between 20 and 90 DEG C, the temperature of the separation kettle I is between 10 and 60 DEG C and the temperature of the separation kettle II is between 5 and 40 DEG C; and after the extraction is completed, concentrating or dehydrating the materials in the separation kettle II, and drying the materials to prepare an oil-soluble or fat-soluble caramel pigment product. The method has the characteristics of no pollution, simple process, high product yield and high edible safety.

Description

technical field [0001] The invention relates to caramel pigment, in particular to a method for preparing edible safe oil-soluble and fat-soluble caramel pigment, and belongs to the field of green food processing. Background technique [0002] Caramel color (Caramel color) is one of the food colorings with the longest history of human use, and it is also the most widely used and most popular food additive currently used by people. Caramel coloring is not a single compound (approximately 100 different compounds), and its physical properties are brown, brown to black liquid or solid. Chinese invention patent CN1450122 discloses a method for Maillard reaction of amino acid and glucose to produce a Maillard reaction product. The method heats a mixed solution of glucose and amino acid, and reacts at 120°C to 150°C for 2 to 3 hours to prepare a food additive product. Chinese Invention Patent Application 03159243.0 discloses the preparation method of caramel coloring. Heating the h...
