Problems solved by technology

When adopting the lactic acid hydrolysis method, due to the limitation of the lactic acid concentration and the pearl particle size, the concentration of the obtained pearl powder is low, so that the obtained pearl dry powder is also relatively low, and the production cost is relatively high

Embodiment 1

[0013] (1). Use a high-pressure homogenizer to crush the pearls into particles with a particle size of 2 to 3 microns;

[0014] (2). Be the pearl particle of 30wt% citric acid aqueous solution dissolving step (1) with concentration, obtain the pearl powder solution that concentration is 20wt%;

[0015] (3). With sodium bicarbonate, the pH value=7 of the hydrolyzed pearl powder solution in step (2) is left to stand at room temperature to obtain the pearl powder colloid, so that the particle size of the pearl powder reaches nanoscale;

[0016] (4). The nanoscale pearl powder colloid of step (3) is dried by centrifugal spray drying method, solidified and granulated to obtain pearl powder with a particle size of 55 nanometers.

Embodiment 2

[0018] (1). Using a high-pressure homogenizer to crush the pearls into particles with a particle size of 2 to 5 microns;

[0019] (2). Be the pearl particle of 50wt% gluconic acid aqueous solution dissolving step (1) with concentration, obtain the pearl powder solution that concentration is 30wt%;

[0020] (3). With sodium bicarbonate, the pH=7.5 of the hydrolyzed pearl powder solution in step (2) is left to stand at room temperature to obtain the pearl powder colloid, so that the particle size of the pearl powder reaches nanoscale;

[0021] (4). The nanoscale pearl powder colloid of step (3) is dried by a centrifugal spray drying method, solidified and granulated to obtain a pearl powder with a particle size of 80 nanometers.

Abstract

The present invention relates to pearl powder preparation, and is especially the preparation of nano level pearl powder. The preparation process includes crushing pearl in high pressure homogenizing machine into grains of 2-5 micron size; dissolving pearl grains with citric acid or gluconic acid aqua to obtain pearl solution of 3-20 wt% concentration; regulating the pH value of pearl solution to neutrality; letting stand at room temperature to obtain pearl colloid; drying, solidifying and pelletizing to obtain pearl powder of 50-90 nm size. The said process has short time and high yield.

Description

technical field [0001] The invention belongs to the field of pearl powder processing, in particular to a preparation method of nano-scale pearl powder. Background technique [0002] Because pearls contain more than 20 kinds of amino acids and trace elements needed by the human body, protein and a large amount of calcium, etc., it is a kind of precious Chinese medicinal materials and nutritional health products. In order to make full use of the substances needed by the human body contained in pearls, people process pearls into beverages or supplements for human health care. But, when processing pearl, because pearl has hard concentric laminated structure, it is quite difficult to process it into powder. The traditional processing methods for pearls include: boil the pearls in water for several times until they soften, and then grind them in water; or directly add water to the pearls and crush them with a general coarse crusher, and then use a ball mill to crush them in the s...
