Embodiment 1

[0020] Embodiment 1 sharp hole method prepares the quality assessment of black fruit wolfberry pigment microcapsules and pigment microcapsules, comprises the following steps:

[0021] (1) The dried fruit of Lycium barbarum (or the fresh fruit of Lycium barbarum plant dried and crushed at room temperature, or baked at 40°C to 120°C for 2 to 48 hours) was removed and crushed, and 10g was weighed, With hydrochloric acid concentration is 0.3% leaching 20h under the ethanol solvent of 75% at normal temperature, and solid-liquid ratio is 1: 50 (v / v), puts into the microwave extractor and extracts 20min then, and microwave radiation power is 70W, and extracting solution is passed through 8000r / min centrifuge filtered 20min and collected the supernatant, and the residue was extracted 3 times in a microwave extractor with a 75% ethanol solution of 0.3% hydrochloric acid concentration, and each solid-liquid ratio was 1: 30 (v / v), the microwave radiation power is 70W, and the obtained e...

Embodiment 2

[0052] Embodiment 2 A method for preparing black fruit wolfberry pigment antioxidant active microcapsules, comprising the following steps:

[0053] (1) Crush the dried fruit of Lycium barbarum after removing impurities, weigh 10g, extract with 95% ethanol solvent containing 0.1% HCl at room temperature for 12 hours, the ratio of solid to liquid is 1:30, and then put it into microwave extraction Extract in the instrument for 15min, the microwave radiation power is 80W, the extract is filtered by a 6000r / min centrifuge for 15min, the supernatant is collected, and the residue is extracted twice in the microwave extractor with 95% ethanol solution containing 0.1% HCl , each solid-liquid ratio is 1:30, the microwave radiation power is 80W, and the obtained extract is filtered through a 6000r / min centrifuge for 15min to collect the supernatant, combine the extract, concentrate under reduced pressure, reclaim ethanol, and obtain Black fruit wolfberry pigment concentrate.

Abstract

The invention discloses a method for preparing lycium ruthenicum pigment microcapsules by using a piercing method. The method comprises the following steps of using lycium ruthenicum fresh fruits or lycium ruthenicum dried fruits to serve as raw materials, crushing, conducting acidity ethanol digestion, extracting by using a microwave extractor, extracting residues for 2-3 times by using the acidity ethanol after filtering, combining an extracting solution, and conducting decompression concentration to obtain a pigment concentrated solution; and conducting adsorption, elution, desorption and decompression concentration on the pigment concentrated solution through macroporous resin, adding an embedding medium in proportion, conducting solidification, filtering, laminating, filtering and return soaking, drying under ordinary pressure at the temperature of 40-50 DEG C to obtain the lycium ruthenicum pigment microcapsules. An embedding ratio of the lycium ruthenicum pigment microcapsules prepared by the process is 70%-80%, lycium ruthenicum pigments have a slow release function after microencapsulation, more than 70% pigments can be released within 24 hours, the shape is kept to be complete, stability of the lycium ruthenicum pigment microcapsules in an 75% of relative humidity environment is obviously improved, and the weight increase of the microcapsules caused by moisture absorption is lower than 10%.

Description

technical field [0001] The invention relates to a method for preparing black wolfberry pigment microcapsules by adopting a sharp hole method. Background technique [0002] Lycium barbarum is rich in anthocyanin, which is a rare natural anthocyanin pigment resource. Black fruit wolfberry has good yield, and its pigment can be dyed and has certain medical and health care functions. Modern medical research has proved that the fruit extract of Lycium barbarum has the effects of lowering blood fat, regulating immunity, treating cardiovascular system diseases, anti-arteriosclerosis, and anti-tumor, but the stability of Lycium barbarum pigment is poor, such as being susceptible to moisture and oxidation etc., leading to a decrease in pigment usage. Contents of the invention [0003] The object of the present invention is to provide a method for preparing black wolfberry pigment microcapsules that adopt low-temperature concentration and normal-pressure drying technology to devel...
