Embodiment 1

[0027] Method for artificially breaking dormancy of saffron

[0028] Since mid-May 2014, 100 saffron bulbs were selected and cultivated on shelves indoors. The room temperature was controlled at about 25°C and the light was mainly light and dark; Seal the bag and place it in a refrigerator at 4°C for 1 month at low temperature; from mid-August to mid-September, put the saffron on the shelf and continue to place it indoors to avoid light for cultivation. The indoor temperature is controlled at about 25°C and the relative humidity is 80%; September From mid-October to mid-October, control the indoor temperature to around 22°C, relative humidity to 80%, and avoid light; from late October to mid-November, control the indoor temperature to around 16°C, relative humidity to 75%, and no shading indoors.

[0029] Another control group was set up, and 100 saffron bulbs were selected, which were not treated with artificial low-temperature breaking dormancy, and all were cultivated indoo...

[0032] Effects of different flower picking periods on the content of crocin in finished silk products

[0033] In November 2014, flowers of different flowering stages ( figure 1 ), select four time points for the flowering period: 3 days before flowering (-3d), 2 days before flowering (-2d), 1 day before flowering (-1d), and flowering period (0d). Flowers at anthesis (0d) were used as controls. Separate the filaments, and dry the filaments in an oven at 100°C. According to the method stipulated in "Chinese Pharmacopoeia", the content of crocin in saffron filaments at different flowering stages was determined. The standard products of crocin I and crocin II were purchased from Shanghai Jingke Chemical Technology Co., Ltd. The measurement results are as follows:

[0034] flowering period

[0035] 0d

[0036] It can be seen that the content of crocin in filaments is different at different flowering stages, and the content is the highest 3 days before flowe...

[0038] Effects of Different Drying Temperatures on the Content of Crocin in Filigree Finished Products

[0039]In November 2014, the flowers 2 days before flowering were selected, the filaments were separated, and different drying temperatures (40°C, 60°C, 80°C, 100°C) were set, and the filaments were dried in an oven. According to the method stipulated in "Chinese Pharmacopoeia", the influence of different drying temperatures on the content of crocin in saffron filaments was determined. The standard products of crocin I and crocin II were purchased from Shanghai Jingke Chemical Technology Co., Ltd. The measurement results are as follows:

[0040] drying temperature

[0041] It can be seen that the content of crocin is the highest at 100°C, reaching 38.58%, which is 3 percentage points higher than other drying temperatures. The three drying temperatures of 40°C, 60°C and 80°C did not change the content of crocin significantly, and the content was slightly higher at...

Abstract

The invention provides a production processing method for crocus sativus. The method comprises the following steps: (1) carrying out artificial dormancy breaking on corms of crocus sativus in mid-July to mid-August; (2) carrying out indoors-shelved cultivation on the artificial-dormancy-broken corms of crocus sativus indoors from mid-August to mid-November; (3) carrying out deflowering 0-3 days before flowering, and carrying out separation so as to obtain filaments; (4) baking the filaments at the temperature of 40-100 DEG C; and (5) hermetically storing the baked filaments at a temperature at or below 10 DEG C. According to the method, the dormancy of crocus sativus can be broken in advance by an artificial dormancy breaking method so as to promote early flowering, early planting and early rooting and facilitate sound seedlings, and the content of effective ingredients in the filaments is not affected. In addition, through regulating and controlling a flower picking period, a filament baking temperature and a filament storage temperature, the content of effective ingredients in crocus sativus filament finished products is increased, the quality of the finished products is improved, and the value of the finished products is increased. The synergistic application effect of four methods concerned by the invention is relatively good, and the four methods provided by the invention can be subjected to development and application as a whole.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine cultivation and processing, in particular to a production and processing method of saffron. Background technique [0002] Saffron (Crocus sativus L.), also known as saffron and saffron, is a perennial plant of the genus Crocus in the family Iridaceae, and is also a common spice. It is mainly distributed in Europe, the Mediterranean and Central Asia, and is cultivated in Beijing, Shandong, Zhejiang and Sichuan in China. Saffron is a kind of precious Chinese medicinal material. It has three red stigmas on the upper part of the pistil. It has various effects such as lowering blood fat, and also has good immunity-enhancing and anti-tumor activities. [0003] Saffron is suitable for mild, humid winters and cool, dry summers. In our country, the "two-stage" cultivation method is often adopted, that is, the bulbs are dug out of the ground in May of that year, and the indoor cultiv...
