Embodiment 1

[0021] 1) Pick fresh mushrooms, put them in a blender and stir them into a slurry;

[0022] 2) Add water to the slurry in step 1) at a mass ratio of 1:5, heat to 85°C while stirring for 25 minutes;

[0023] 3) filtering the product in step 2) to remove the filter residue, and collecting the filtrate;

[0024] 4) adding an organic solvent with a pH value of 2.5-3.5 to the filtrate obtained in step 3) for ultrasonic-assisted extraction, the volume ratio of the filtrate to the organic solvent is 1:9, and the extraction conditions are: in an ultrasonic cell pulverizer with Ultrasonic treatment with a power of 300-400W for 10 minutes; then extract in a water bath at 40°C to obtain an extract;

[0025] 5) Dry the product obtained in step 4) at 100° C. for 1.5 hours, and then extract the yellow pigment from the powdered pigment product obtained by drying.

Embodiment 2

[0027] 1) Pick fresh mushrooms, put them in a blender and stir them into a slurry;

[0028] 2) Add water to the slurry in step 1) at a mass ratio of 1:10, heat to 100°C while stirring for 35 minutes;

[0029] 3) filtering the product in step 2) to remove the filter residue, and collecting the filtrate;

[0030] 4) Adding an organic solvent with a pH value of 2.5-3.5 to the filtrate obtained in step 3) for ultrasonic-assisted extraction, the volume ratio of the filtrate to the organic solvent is 1:11, and the extraction conditions are: in an ultrasonic cell pulverizer with Ultrasonic treatment with 300-400W power for 20 minutes; then extract in a water bath at 45°C to obtain the extract;

[0031] 5) Dry the product obtained in step 4) at a temperature of 120°C for 2.5 hours, and then extract the yellow pigment from the powdered pigment product obtained by drying.

Abstract

The present invention discloses a method for extracting yellow pigment from physalis alkekengi fruits. The method solves problems that existing yellow pigment extraction methods are low in extraction rate, large in consumption of an organic solvent and time-consuming, oxidative decomposition of the yellow pigment is easy to occur in an extraction process, and supercritical extraction is not capable of performing industrial mass production. The method provided by the present invention has advantages of being simple in equipment and manufacturing process and high in pigment yield.

Description

technical field [0001] The present invention relates to the extraction of yellow pigment. More specifically, it relates to a method for extracting the yellow pigment from the fruit of the mushroom. Background technique [0002] Mushroom Niang (commonly known as "Huang Mushroom Niang"), the fruit is a spherical berry, the size of a grape, surrounded by enlarged persistent calyx and shaped like a lantern. The mature fruit and persistent calyx all turn apricot yellow, and fall off from the fruit branch and fall to the ground together. Mature mushrooms have a mixed flavor of grapes, strawberries, and cantaloupe. They are sweet but not greasy, slightly acidic, and delicious. Physalis fruit can be eaten directly after ripening, the taste is sweet and sour, the color is bright and orange-yellow. It can be used as a good raw material for food processing. The fruit contains a variety of nutrients needed by the human body. It is widely distributed in the northeast and has a high ...
