Description

Technical Field

[0001] This utility model relates to the field of corn waxiness detection, and in particular to a rapid identification kit for corn waxiness. Background Technology

[0002] Corn is one of the world's most important food crops. According to the physicochemical properties of endosperm starch, it can be mainly divided into common corn, waxy corn, sweet corn and other types. Among them, waxy corn has unique edible and economic value because its endosperm starch is almost entirely amylopectin. After cooking, it is soft, sticky and elastic, with excellent taste. Its demand is growing in the fields of fresh food, food processing and industrial applications.

[0003] Currently, the simplest method for detecting the waxiness of corn is the iodine staining method. The starch in non-waxy corn varieties is amylose, which turns blue-black when it comes into contact with iodine, while the starch in waxy corn varieties is amylopectin, which turns brownish-red when it comes into contact with iodine. After iodine staining, the two types of pollen grains can be clearly distinguished. However, existing staining methods mostly involve placing broken corn kernels in a container and then pouring in iodine solution for testing. This method is not convenient for controlling the amount of iodine solution poured in during operation and requires carrying iodine solution and a measuring container, making it inconvenient to use. Therefore, we propose a rapid identification kit for waxy corn to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid identification kit for the waxy properties of corn, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A rapid identification kit for waxy corn includes a box body with a lid hinged to its outer surface. A detection groove and a recess are formed on the upper surface of the box body. An iodine syringe is fixedly connected inside the recess, and a sliding push plate is slidably connected inside the recess. The iodine syringe includes an injection cylinder fixed inside the recess, with an injection nozzle fixedly connected to its left end. The left end of the injection nozzle passes through the recess and communicates with the detection groove. A piston is provided inside the injection cylinder, with a push rod fixedly connected to one end of the piston. The right end of the push rod is connected to the left side of the sliding push plate.

[0006] In a further embodiment, the outer surface of the iodine syringe is provided with graduation lines, and the interior of the iodine syringe is provided with iodine solution.

[0007] In a further embodiment, a protective cover is snapped into the inside of the detection slot, and a pinch flap is fixedly connected to the outer surface of the protective cover.

[0008] In a further embodiment, two grooves are formed on the upper surface of the box body, and a slider is slidably connected inside each groove. The upper surface of each slider is connected to the bottom surface of the sliding push plate.

[0009] In a further embodiment, a fixing strap is fixedly connected to the outer surface of the box lid, and Velcro is fixedly connected to the bottom surface of the fixing strap and the right side of the box body. The box lid is connected to the box body by Velcro, and an instruction label is affixed to the upper surface of the box lid.

[0010] In a further embodiment, two limiting plates are fixedly connected to the inner wall of the box cover, and each limiting plate is adapted to the sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device highly integrates all functions, including sample placement, reagent storage, quantitative dispensing, and reaction observation, into a compact box. Users only need to carry this one reagent kit to complete the entire testing process in the field, laboratory, or purchasing site. It integrates an iodine syringe with graduated lines, allowing operators to precisely control the stroke of the sliding push plate by observing the graduated lines, thereby injecting accurate and quantitative iodine solution from the injection nozzle into the testing tank. This avoids the problems of uncontrollable and random iodine solution volume caused by traditional pouring methods, ensuring consistent iodine solution volume for each test. This greatly improves the standardization of the testing method and the comparability of results, providing a fundamental guarantee for accurately identifying the waxy nature of corn.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This invention discloses a rapid identification kit for waxy corn, comprising a box body 1, a box cover 2 hinged to the outer surface of the box body 1, a detection groove 3 on the upper surface of the box body 1, a groove 10 on the upper surface of the box body 1, an iodine syringe 5 fixedly connected inside the groove 10, and a sliding push plate 8 slidably connected inside the groove 10. This kit integrates all functions such as sample placement, reagent storage, quantitative injection, and reaction observation into a compact box body 1. Users only need to carry this kit to complete the entire set of testing operations in the field, laboratory, or purchasing site. When the kit leaves the factory, the syringe 501 of the iodine syringe 5 is pre-filled with a standard potassium iodide solution, i.e., iodine solution, and the scale line 6 can be used to observe or calibrate the liquid volume.

[0021] The iodine injector 5 includes an injection cylinder 501 fixed inside the groove 10. The left end of the injection cylinder 501 is fixedly connected to an injection nozzle 502. The left end of the injection nozzle 502 passes through the groove 10 and communicates with the detection groove 3. The injection cylinder 501 is equipped with a piston 503. One end of the piston 503 is fixedly connected to a push rod 504. The right end of the push rod 504 is connected to the left side of the sliding push plate 8. The outer surface of the iodine injector 5 is provided with a scale line 6. The iodine injector 5 is filled with iodine solution. By observing the scale line 6, the operator can accurately control the stroke of the sliding push plate 8, thereby injecting accurate and quantitative iodine solution from the injection nozzle 502 into the detection groove 3, avoiding the problems of uncontrollable and random iodine solution volume caused by the traditional pouring method.

[0022] The inside of the detection slot 3 is fitted with a protective cover 4, and the outer surface of the protective cover 4 is fixedly connected with a pinch flap 9. The upper surface of the box body 1 has two sliding grooves 7, and each sliding groove 7 is slidably connected with a slider 14. The upper surface of each slider 14 is connected to the bottom surface of the sliding push plate 8. The detection slot 3 is equipped with a detachable protective cover 4, which can prevent iodine liquid from splashing and protect the operator, and can also be easily removed during observation. The slider 14 at the bottom of the sliding push plate 8 slides smoothly in the sliding groove 7 to ensure a straight pushing stroke.

[0023] A fixing strap 12 is fixedly connected to the outer surface of the lid 2. Velcro 11 is fixedly connected to the bottom surface of the fixing strap 12 and the right side of the box body 1. The lid 2 is connected to the box body 1 via Velcro 11. An instruction label 15 is affixed to the upper surface of the lid 2. The entire reagent kit has an ingenious design without complex precision parts. It is mainly made of low-cost materials such as plastic, and the manufacturing process is simple. The instruction label 15 is intuitive and easy for users to quickly master the operation method. This low-cost and easy-to-operate characteristic makes the reagent kit very suitable for large-scale promotion and use by agricultural extension personnel, seed quality inspectors, growers, and grain purchasing personnel. Two limiting plates 13 are fixedly connected to the inner wall of the lid 2. Each limiting plate 13 is adapted to the sliding groove 7. When the lid 2 is closed, the two limiting plates 13 on its inner wall will precisely engage with the sliding groove 7 on the box body 1. This design physically blocks the movement of the sliding push plate 8 during transportation and storage, thereby preventing accidental push of the push rod 504 and leakage of iodine solution, thus playing a safety locking role.

[0024] The working principle of this utility model is as follows: In use, first unfasten the Velcro 11 connecting the box body 1 and the box cover 2, open the box cover 2, take 1-2 corn kernels to be tested, and gently break or cut them with a blade or tweezers to expose the internal endosperm. Place the processed corn kernels into the detection groove 3 on the upper surface of the box body 1. When the kit is shipped, the syringe 501 of the iodine syringe 5 is pre-filled with a standard iodine solution. The scale line 6 can be used to observe or calibrate the liquid volume. The operator pushes the sliding push plate 8 to the right with their finger. The slider 14 at the bottom of the sliding push plate 8 slides smoothly in the groove 7 to ensure a straight advance. The sliding push plate 8 pushes the piston 503 in the syringe 501 to the left through the push rod 504. The pre-stored iodine solution is quantitatively and controllably injected into the detection tank 3 through the injection nozzle 502, just enough to submerge or cover the corn kernel sample in the tank. The end point of the injection stroke is usually designed to discharge a predetermined amount of iodine solution, such as 1-2 drops, avoiding the problem of difficult dosage control in the traditional pouring method. After standing for about 30 seconds to 1 minute, the iodine solution reacts fully with the corn endosperm starch. The color change of the corn kernel cross-section is directly observed through the detection tank 3: if the kernel cross-section is bluish-black, it indicates that its starch is mainly amylose and is judged as non-glutinous corn; if the kernel cross-section is brownish-red or reddish-brown, it indicates that its starch is mainly amylopectin and is judged as glutinous corn.
