Problems solved by technology

[0003] The 2015 edition of "Chinese Pharmacopoeia" contains raspberry processed products, but it only stipulates general principles, without scientific and specific process parameters. In actual production, it can only be processed by the experience of workers, and it is difficult to guarantee the quality of the processed pieces.
[0015] It retains the original ecology and nutrients of the mature palm leaf raspberry by adopting freezing treatment and freeze-drying. However, due to the freezing and drying treatment at -45~-35°C, although it still retains the shape of the raspberry, it has already There is no inside of raspberry at all, the internal material form and its taste are completely different, and it basically does not have the good taste required for edible
lost its edible value

Embodiment 1

[0030] Remove the stems and leaves of fresh raspberries, wash them, put them in boiling water for 20 seconds, drain the hot raspberries, and dry them at 30°C for 8 hours. When the surface of raspberries turns yellow-green, place them in In the channel, the edible powder with a particle size of 600nm is passed through the channel to immerse the inside of the raspberry, and then the pure air is passed through the channel to remove the powder on the surface of the raspberry. Heating under the microwave of -930MHz, drying until the surface of the raspberry is gray-green, the water content is lower than 8%, and the raspberry decoction pieces are obtained. The concentration of the edible powder is 5g / m 3 ; The edible powder is raspberry powder; The flow velocity of the edible powder is 1 m / s.

Embodiment 2

[0032] Remove the stems and leaves of fresh raspberries, wash them, put them in boiling water for 100s, drain the scalded raspberries, and dry them at 50°C for 4 hours. When the surface of raspberries turns yellow-green, place them in In the channel, the edible powder with a particle size of 1000nm is passed through the channel to immerse the inside of the raspberry, and then the above-mentioned treated raspberry is heated under a microwave with a frequency of 900-930MHz, and dried until the surface of the raspberry is gray-green, Moisture content below 8%, obtain raspberry slices. The concentration of the edible powder is 80g / m 3 ; The edible powder is Polygonatum Chinese herbal medicine powder, and the flow velocity of the edible powder is 2 meters per second.

experiment example 1

[0036] Measure the water-soluble extract content, ellagic acid content and kaempferol-3-0-rutinoside content of raspberry decoction pieces.

[0037] Determination of water-soluble extract content: take about 2-4g of the test sample, accurately weigh it, put it in a 100-250ml Erlenmeyer flask, add 50-100ml of water precisely, seal it tightly, weigh it, and let it stand for 1 hour. Connect the reflux condenser, heat to boiling, and keep boiling slightly for 1 hour. After cooling, remove the Erlenmeyer flask, seal it tightly, weigh again, make up for the lost weight with water, shake well, filter with a dry filter, accurately measure 25ml of the filtrate, and place it in an evaporating dish that has been dried to constant weight , evaporated to dryness on a water bath, dried at 105°C for 3 hours, cooled in a desiccator for 30 minutes, and quickly and accurately weighed. Unless otherwise specified, the content (%) of water-soluble extractives in the test product shall not be less...

Abstract

The invention belongs to the field of processing and preparation of Chinese medicinal materials, and in particular relates to a preparation method of raspberry decoction pieces. Fresh raspberries are removed from stems and leaves, washed, put into boiling water for 20-100s, and scalded Drain the water from the raspberries and dry them at 30-50°C for 4-8 hours. When the surface of the raspberries turns yellow-green, place them in the channel, and pass the edible powder with a particle size of 500-1500nm through the channel to immerse the raspberries Inside, the above-mentioned treated raspberries are then heated under microwaves with a frequency of 900-930MHz, and dried to the surface of the raspberries in gray-green, with a water content lower than 8%, to obtain raspberry decoction pieces. The present invention not only keeps the raspberry Nutrients, but also retains the shape and taste of some fresh raspberries, prolongs the storage time of raspberries, and has dual-purpose food and medicine.

Description

technical field [0001] The invention belongs to the field of processing and preparation of Chinese medicinal materials, and in particular relates to a preparation method of raspberry decoction pieces. Background technique [0002] Raspberry, also known as East China raspberry, big horn male, milk mother and raspberry. The immature fruit is used as medicine. It has the functions of nourishing the kidney, strengthening essence and reducing urination. It is used for kidney deficiency, frequent urination, impotence, premature ejaculation, and nocturnal emission. [0003] The 2015 edition of "Chinese Pharmacopoeia" contains raspberry processed products, but it only stipulates general principles, without scientific and specific process parameters. In actual production, it can only be processed by the experience of workers, and it is difficult to guarantee the quality of the processed pieces. . Raspberry decoction pieces are different from general Chinese herbal medicines. Common...
