Problems solved by technology

[0004] For example, according to the "Reference Test Manual for Evaluation of Freshness Life of Cut Flowers", the "shelf life" of cut flowers is evaluated by checking the actual changes in cut flowers based on a questionnaire, but the evaluation criteria are complicated, and it is difficult to always reflect the impact of cut flowers on temperature changes during distribution. influences

Embodiment approach 1

[0053]

[0054] figure 1 A calculation example of the required integral temperature (temperature [° C.]×time [h], also referred to as a temperature time value) in the circulation stage of cut flowers is shown.

[0055] Such as figure 1 As shown, in the producer (farmhouse), 25° C.×8 hours in picking flowers and 272° C.·h in 6° C.×12 hours in storage thereof are required cumulative temperatures.

[0056] In addition, in the transportation from the producer (farmhouse) to the market, 70℃·h of 7℃×10h in the case of refrigerated transportation, and 300℃·h of 30℃×10h in the case of normal temperature transportation are necessary accumulations temperature.

[0057] In addition, in the market, 120° C.h of 20° C.×6 hours is a necessary cumulative temperature during storage.

[0058] In addition, in the transportation from the market to the bouquet maker, in the case of refrigerated transportation, 35°C·h of 7°C×5h, and in the case of normal temperature transportation, 150°C·h of ...

Embodiment 1

[0071] Aqueous solutions of xylose and glycine were prepared.

[0072] A plurality of xylose aqueous solutions were prepared by mixing xylose and water and adjusting the concentration of xylose to 2.0M to 3.5M.

[0073] Prepared multiple glycine, Na 2 HPO 4 Mix with water and adjust the concentration of glycine to 2.0M~2.5M, Na 2 HPO 4 Glycine aqueous solution with a concentration of 0.2M to 0.4M.

[0074] [Table 1]

[0075]

[0076] Two transparent bags made of polyethylene terephthalate were prepared. One transparent bag A is 45×30×1mm, and the other transparent bag B is 30×20×1mm. 500 μL of xylose aqueous solution was poured into the transparent bag B and heat-sealed. An indicator was produced by injecting 1000 μL of a glycine aqueous solution into the transparent bag A, putting it into the transparent bag B, and then heat-sealing it. By pressing the sealed portion (closed portion) of the inner transparent bag B with a finger, the xylose aqueous solution and the ...

Embodiment 2

[0087] In Example 1, culture was carried out at 5°C or 10°C, but in this example, the indicator of condition 5 was used and culture was carried out at 3°C. Figure 4 It is a graph showing the temperature change and the color change of the indicator in Example 2. Figure 4 (A) is the temperature change in the incubator, Figure 4 (B) is the color change (photograph) of the indicator (Condition 5). In addition, the color bar on the photo is based on the RGB value (RGB_value) of the digital image analysis of the photo, and (R value, G value, B value) are shown below the photo. Also, the values ​​on the color bar are cumulative temperatures. In addition, temperature changes in the incubator (inside the box) were recorded by a data recorder (Thermo Recorder TR-7wf, GRAPHTEC midiLOGER GL240).

[0088] Such as Figure 4 As shown in (B), in the indicator of condition 5, the color changes from transparent to light blue around the cumulative temperature of 500°C·h in culture at 3°C,...

Abstract

Provided is an indicator capable of determining an accumulated temperature of about 500 DEG C.h and about 1000 DEG C.h, which is an important index when performing quality management for cut flowers. This indicator has a first bag P1 containing a first component solution L1 and a second bag P2 containing a second component solution L2, pushing the indicator causes the first component solution and the second component solution to come into contact, and the Maillard reaction causes a first discoloration from transparent to pale blue and a second discoloration from blue to brown. The first component solution has a sugar and a solvent, and the second component solution has an amino acid, a pH adjuster, and a solvent. For example, when the indicator is transparent, it is determined that the accumulated temperature is no higher than 500 DEG C.h, and when the indicator is blue, it is determined that the accumulated temperature is no higher than 1000 DEG C.h. Thus, the accumulated temperature can be easily confirmed at a glance, and the subsequent 'longevity' of cut flowers can be determined.

Description

technical field [0001] The invention relates to an indicator for flower quality management and a flower quality management method. Background technique [0002] Flowers have various charms, and they circulate in their own forms to enrich life. In particular, cut flowers are widely distributed because they are easy to appreciate. For example, flowers grown by farmers (producers) who sell flowers are harvested (picked) and turned into cut flowers. Harvested cut flowers are bundled into bundles of 10 to 20, and bundles are packed in cardboard boxes in a flat state for shipment. For example, the shipped cut flowers are concentrated in the market and delivered to consumers via bouquet manufacturers and retail stores (supermarkets, etc.). [0003] Among such cut flowers, there is a "shelf life" as a large index for determining the commercial value thereof. Among markets, bouquet manufacturers, retail stores (supermarkets, etc.) and consumers, the "how long" of cut flowers is t...
