Shape and color protection method for paeonia lactiflora

Abstract

The invention discloses a method for preparing dehydrated dried paeonia lactiflora. The method comprises the following steps: sieving cottonseed meal through a sieve with the mesh size in a range of 60-250 mesh to obtain fine cottonseed meal, sieving corncob powder through a sieve with the mesh size in a range of 60-250 mesh to obtain fine corncob powder, uniformly mixing the fine cottonseed meal with the fine corncob powder, and performing heating and drying at 40-90 DEG C to obtain a dehydrating matrix; providing integrated paeonia lactiflora which are uniform in size and are bright-colored and glossy; performing trimming to the selected integrated paeonia lactiflora; soaking the trimmed integrated paeonia lactiflora in a citric acid solution with the mass concentration being 0.5-2.5% for 5-20 min for color protection; and embedding the obtained in the dehydrating matrix for dehydration, wherein during embedding, the temperature of the dehydrating matrix is no less than 40 DEG C, and the dehydrating time is 4-20 h, and after dehydration is completed, removing the dehydrating matrix to obtain the dehydrated dried paeonia lactiflora. The dried paeonia lactiflora prepared through the method has a good shape and color protection effect.

Description

technical field [0001] The invention belongs to the field of flower processing, and in particular relates to a method for protecting the shape and color of peony flowers. Background technique [0002] Paeonia lactiflora (scientific name: Paeonia lactiflora Pall.), also known as Jiangli, Licao, and the prime minister in the flower, belongs to the order Cinnamoniaceae, and is a perennial herbaceous flower in the family Ranunculaceae Paeoniae. Root tubers are born from the bottom of the root neck, fleshy, thick, fusiform or long columnar, 0.6-3.5 cm thick. The petals of peony are obovate, and the disk is shallow cup-shaped. The flowering period is from May to June. It usually blooms alone at the top of the stem or in the axils near the top. The original flower is white, with 5 to 13 petals. The horticultural varieties are rich in flower colors, including white, pink, red, purple, yellow, green, black and multi-color, etc. The flower diameter is 10-30 cm, and the petals can rea...

Problems solved by technology

[0004] The main method of processing dried flowers is the traditional silicate adsorption method, also known as the embedding method, one of which is the separation and embedding method. In this method, the flowers and branches and leaves are separated, dried separately, and then spliced; this method requires manual operation. , many procedures, heavy labor, inconvenient mass production; in addition, this method needs to separate the petals, so it cannot meet the drying needs of multi-round petal varieties

In the prior art, chemical techniques are also used to process fresh flowers and dried flowers. For example, freeze-drying technology is used to make dried flowers, which can better maintain the shape and color of dried flowers and prolong their shelf life; Small, the petals are extremely crisp, the texture is not ideal, the processing technology is not good, and the cost is extremely high
