Description

Monascus color color lake and preparation method thereof

Technical field the present invention relates to color lake class pigment and preparation method thereof, particularly Monascus color color lake and red colouring agent for food, also used as a Chinese medicine yellow lake and preparation method thereof.

The background technology color lake is meant the water-insoluble coloring matter that is precipitated out by water-soluble dye under the effect of dissimilar precipitation agents.Usually require the color lake to have bright-coloured coloured light, good opacifying power, water insoluble, acid, alkali, heat are had stability.Many pigment lake light fastness, look power, coloured light are not very good, and the coloured light of some kind, application performance are subjected to the restriction of working conditions.

In the class pigment of present normally used color lake, commonly used is red azo class pigment lake, but contain the color lake group at the azo-group ortho position usually in the molecule, as sulfonic group, carboxylic acid group, contain polar group simultaneously, as hydroxyl, nitro, halogen etc., its used water-soluble dye is not a natural dyestuff, adopt chemical synthetic dye, and cost is higher.

Chen Xianghong etc. have delivered " about the research in lithol red different metal color lake " on 1989 " dyestuffs industrieies ", the method in lithol red color lake mainly introduced in article, and spectral investigation and analysis have been carried out in seven lithol red color lakes that contain magnesium, calcium, strontium, manganese, zinc and cadmium.

Application number is 03150587.2 innovation and creation " preparation method in the edible color lake of special food additive ", having introduced a kind of aluminum chloride and sodium bicarbonate of adopting is on the basis of matrix, adjust temperature, pH value and the conditions of mixture ratios of color lakeization, the method in the edible color lake of preparation.

Application number is 200410084502.3; Innovation and creation " preparation method of oily color lake as special food additive ", introduced and a kind of compound lard mixed with antioxidant, add edible color lake again and prepare the method in oily color lake.

Summary of the invention the objective of the invention is to develop that a kind of tinting strength is good, the natural monascus color color lake of good stability, and corresponding preparation method is provided.

The objective of the invention is to realize by the following method:

1, adopt the precipitator method to prepare the Monascus color color lake, may further comprise the steps:

(3) precipitation: monascorubin solution is acidified to pH 1～2 with hydrochloric acid or sulfuric acid, in the monascorubin liquor capacity: the precipitant solution volume is that 1.5: 1 ratio adds precipitant solution, stirred 1-2 hour with stirrer then, produce throw out, its molecular structure is:

Wherein, R is C ₅H ₁₁Or C ₇H ₁₅, Me is Ca ²⁺, or Mg ²⁺, or Zn ²⁺, or Ba ²⁺, or Mn ²⁺

(4) filter: adopt 80～200 purpose filter screens or filter membrane to leach throw out, and under 0.08～0.10MPa, vacuumize, remove free-water;

(5) drying: the throw out that will remove behind the free-water places drying plant, and being dried to water ratio under 60 ℃～80 ℃ condition is 1%～5%, promptly obtains the Monascus color color lake.

(6) packing: the Monascus color color lake is ground into powder, then packing.

2, adopt the precipitator method to prepare the red colouring agent for food, also used as a Chinese medicine yellow lake, may further comprise the steps:

(1) preparation precipitant solution: add the 5%-85% precipitation agent in water, described precipitation agent is divalent metal salt Ca ²⁺, or Mg ²⁺, or Zn ²⁺, or Ba ²⁺, or Mn ²⁺, stirring and dissolving is mixed with precipitant solution;

(2) preparation monascus yellow pigment solution: add the 2%-20% monascus yellow pigment in water, stirring and dissolving under 50 ℃～80 ℃ conditions is mixed with monascus yellow pigment solution;

(3) with hydrochloric acid or sulfuric acid monascus yellow pigment solution is acidified to pH 1～2, in the monascus yellow pigment liquor capacity: the precipitant solution volume is that 1.5: 1 ratio adds precipitant solution, stirs 1-2 hour with stirrer then, produces throw out, and its molecular structure is:
