Embodiment 1

[0049] (1) Add 30mg of Monascus pigment powder into 10mL of distilled water, stir to fully dissolve;

[0050] (2) Dissolve 0.3g of sodium alginate and 0.1g of calcium carbonate in 20mL of distilled water, and swell for 1 to 2 hours;

[0051] (3) fully mix the solution obtained in the above (1) and (2);

[0052] (4) Prepare soybean oil 90mL containing 1vt% Span 80;

[0053] (5) Fully mix the solutions obtained in the above (3) and (4), and fully stir with a magnetic stirrer at a speed of 600 rpm for emulsification to obtain a W / O emulsion;

[0054] (6) To the W / O emulsion obtained in (5), slowly add 340 μL of CH 3 20mL of soybean oil in COOH (reduce the pH value of the system), while fully stirring to make it evenly mixed, adding acid will cause Ca 2+ The dissociation of Ca 2+ In the emulsion droplets, it reacts with sodium alginate to form a uniform gel network structure, and wraps the red yeast pigment in the calcium alginate gel beads;

Abstract

The invention discloses monascus pigment microcapsules and a preparation method thereof. The preparation method comprises the following steps: (1) dissolving monascus pigment powder; (2) swelling sodium alginate and calcium carbonate; (3) sufficiently and uniformly mixing; (4) dissolving an emulsifier into first vegetable oil; (5) sufficiently and uniformly mixing solutions obtained by step (3) and step (4); stirring and emulsifying; (6) adding second vegetable oil containing an acid regulator; (7) adding a phosphate buffer solution; (8) standing and carrying out oil phase and water phase separation to obtain wet-state monascus pigment microcapsules; (9) spraying and drying to obtain the sodium alginate and calcium carbonate embedded monascus pigment microcapsules. By adopting the monascuspigment microcapsules and the preparation method thereof, the problems that the color value is not stable when a monascus pigment is applied to food coloring and the monascus pigment is easy to decompose and fade are effectively solved.

Description

technical field [0001] The invention belongs to the field of capsule preparation, and more specifically relates to a monascus pigment microcapsule and a preparation method thereof. Background technique [0002] In recent years, due to doubts about the safety of synthetic pigments, natural pigments have been widely favored by consumers. At present, among the more than 40 kinds of natural food pigments stipulated in my country's national standard, there are only 4 kinds of colorants from microorganisms: Monascus red pigment, Monascus yellow pigment, Monascus rice flour and β-carotene, the first three of which are all red. Aspergillus fermentation product. Monascus pigments include yellow pigments, orange pigments and red pigments, and about 90 components of Monascus pigments have been identified so far. Monascus pigment has the advantages of good color tone, strong protein concentration without side effects, and production is not restricted by raw materials and seasons. In re...
