Problems solved by technology

If the dry matter content is too low, the potato chips will be deformed and wavy during the frying process, the output yield will be low, and more oil will be absorbed, making the oil content too high, resulting in a greasy taste; if the dry matter content is too high, It will make the fried chips too hard and lose the crispy taste; therefore, a suitable dry matter content is required to reduce the oil content in the fried chips and improve the quality and output of the fried chips

specific Embodiment approach 1

[0012] The specific embodiment one, the method for improving potato quality by electron beam irradiation seed potato, its method is: irradiate potato seed potato with electron beam; Described electron beam is the charged particle that accelerator produces, and the dose of electron beam is between 1~6 Gray; dose rate range is 0.02 Gray / sec.

[0013] The irradiation process is done at room temperature.

[0014] The particle size of seed potato is 0.5cm-3cm, which is a defect-free and excellent variety seed potato.

[0015] Select " Eugene " below, " sea potato No. 1 " kind, verify the effect of the present invention. Table 1 shows the quality change data of "Eugene" potato seed potatoes irradiated with different doses of electron beams, and Table 2 shows the quality change data of "Haishu No. 1" potatoes irradiated with different doses.

specific Embodiment approach 2

[0023] Specific embodiment two, combine figure 1 Illustrate this specific embodiment, the device that improves potato quality based on the electron beam irradiation seed potato of specific embodiment one, it comprises accelerator scanning box 1, metal plate 9 and insulating material body 8, the lower surface of metal plate 9 is fixed on insulating material On the upper surface of the body 8, the metal plate 9 is horizontally arranged, and the upper surface of the metal plate 9 is the placement area for the seed potato 5 to be irradiated, and the accelerator scanning box 1 is arranged directly above the metal plate 9, and The electron beam emitting surface of the accelerator scan box 1 faces the metal plate 9 .

[0024] When this embodiment is working, the potato seed potato 5 to be irradiated is placed on the metal plate 9, the area of ​​the insulating material 8 is smaller than the area of ​​the special metal plate 9, and the metal plate completely covers the insulating mater...

specific Embodiment approach 3

[0025] Embodiment 3. The difference between this embodiment and the device for improving potato quality by electron beam irradiating seed potatoes described in Embodiment 2 is that the electron beam emitted by the accelerator scanning box 1 is perpendicular to the horizontal plane where the metal plate 9 is located.

Abstract

The invention relates to a method and device for improving potato quality by electron beam irradiation of a potato seed. By adopting the method, content of starch, dry substances and reducing sugar in a potato is improved so that the potato is more suitable for the purpose of frying. In the method, an electron beam is used for irradiating the potato seed to realize quality improvement. In the device, the lower surface of a metal plate is fixed on the upper surface of an insulating material body, and the metal plate is horizontally arranged; the upper surface of the metal plate is a placement area of the potato seed to be irradiated; and a scanning box of an accelerator is arranged right above the metal plate, and the scanning box faces the metal plate. The method and device provided by the invention are applicable to quality improvement of the potato.

Description

technical field [0001] The invention relates to a method and device for improving potato quality. Background technique [0002] With the change of people's eating habits, potato snack food has a huge market in China, and has brought development and opportunities for related industries. However, there is a shortage of special potato varieties for frying in China, and the imported varieties have problems such as inadaptability to the soil and climate environment and poor disease resistance. Therefore, quality breeding has become the focus of current potato breeding work. The common cultivar potato is autotetraploid and highly heterozygous, and the self-bred offspring are complex to segregate traits based on tetraploid inheritance rules. Therefore, the genetic basis research is relatively lagging behind, and the selection rate of hybrid breeding and mutation breeding is low. [0003] The quality requirements for general fried potatoes are as follows: [0004] 1. General requi...
