Problems solved by technology
In the determination of pedicel color of pine cauliflower bulbs, visual inspection and chlorophyll content determination are the most commonly used methods, but because the visual measurement method is mainly qualitative, it is easy to ignore the transition color and cause experimental errors, and the determination of chlorophyll content needs to be carried out in the experiment. In-room operation, time-consuming and labor-intensive
At present, there is no quantitative analysis method for the pedicel traits of pine cauliflower curd at home and abroad, and there is no recognized standard for judging the peduncle color of the curd

Embodiment Construction
[0027] The following describes the technical solutions in the embodiments of the present invention clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0028] A method for measuring the color of the pedicel in the pine cauliflower bulb with a portable colorimeter, including the following steps: (1) Collection of the pine cauliflower bulb sample: when the pine cauliflower bulb is fully mature, collect it as a curd sample , Keep 2-3 outer leaves outside the curd to protect the curd;
[0029] (2) Preparation of pine cauliflower flower bulb test sample: carefully cut off the outer leaves of the flower bulb, cut the curd sample into a cross shape with the central column as the cent...

The invention discloses a method for carrying out chroma detection of pine cauliflower bulb pedicels by using a portable colorimeter. The problems that a quantitative analysis method for the characteristics of the pedicels of pine cauliflower bulbs is not provided at home and abroad and recognized standards for the chroma of flower bulb pedicels are absent are solved. The method provided by the invention comprises the steps of (1) collection of pine cauliflower bulb samples: (2) preparation of pine cauliflower bulb test samples; (3) preparation before the test of the portable colorimeter; (4)determination and selection of standard test samples; (5) accurate color classification of the flower bulbs and pedicels of various pine cauliflower materials to be measured according to the L *, a *and b * ranges determined in step (4); and (6) determination of samples. According to the invention, visual inspection and the portable colorimeter are combined to evaluate the L *, a * and b * valuesof the measured samples to assist in accurate classification of the chroma of pine cauliflower bulb pedicels.
Description
Technical field [0001] The invention relates to the technical field of optical and chromatographic analysis of agricultural products, in particular to a method for measuring the pedicel chromaticity in pine cauliflower bulbs with a portable color difference meter. Background technique [0002] Pine cauliflower is a special type of cauliflower (Brassica oleracea Linnaeus var.botrytis Linnaeus), and a variant of Brassica spp. in the cruciferous family. Because of its long buds, thin flower layers, and full blooms It is not compact and is loose compared to ordinary cauliflower, hence the name. Song cauliflower was first grown and consumed in the Taiwan Strait region of my country. In recent years, it has been quickly promoted from Fujian and Taiwan to East China and Central China. Song cauliflower has the characteristics of green and long pedicels and crisp and sweet taste. However, in actual production, the color of the stalk of the pine cauliflower bulbs exists. There is a big dif...
