Soy
Non-genetically modified soybeans: Heilongjiang real estate soybeans Mature, selected Heilongjiang real estate soybeans are round, full-grained, and bright yellow in color. Except for anti-gland cultivars planted in parts of northern Heilongjiang, the outer umbilicus is light yellow; There is a black umbilicus.
GM Soybeans: Imported genetically modified soybeans collected from harbors are oblate or elliptical and have a dark yellow color. The obvious difference from domestic soybeans is that the bean umbilicals are yellow-brown, commonly known as “black umbilical beansâ€.
Simple test method: GM soybeans do not germinate! Can be detected with water! Native soybeans will germinate after being soaked in water for three days! Genetically modified soybeans will not germinate, but merely inflated.
From this germination test process, one can find that these genetically modified soybeans are fruits produced once, and their germs do not have the essential activity of life. Therefore, there is no ability to continue their offspring. Equivalent to one person can be normal pregnancy, but each time is stillbirth, which means that the continuation of life has ended. If humans have long-term consumption of various genetically modified foods, the genetically modified fragments that are harmful to humans will inevitably affect people's normal genes, reduce their resistance, cause diseases, or lose fertility. Now.
2. Carrot
Non-transgenic carrots: The surface is uneven and generally not straight, from head to tail from coarse to fine. And the head is protruding outwards.
Genetically modified carrots: The surface is relatively smooth, generally straight, and its tail is sometimes thicker than the middle. And the head is concave inwards.
Note: Carrots are only available in autumn and winter seasons, and summers are generally genetically modified.
3. Potatoes
Non-GM potatoes: The appearance is rather ugly. Generally, the color is deep, the surface is pitted, and the skin color is irregular. After peeling, the surface will darken quickly and the skin is white.
GM potatoes: The surface is smooth, the pits are shallow and the colors are light. After peeling, the surface did not change significantly.
Test method: Peel the skin first and then see the changes before deciding not to eat.
4. Maize
GM corn: sweet, crisp, full, beautiful shape, similar to the head and tail particles.
5. Rice
The area where the right to plant genetically modified rice is legally planted in China is Hubei. Be alert to the slender, bright rice. It is easy to be confused with the "long grain incense" in the northeast. Be sure to see the country of origin when you buy it.
6. Tomatoes
Transgenic tomatoes: Bright red color looks good, fruit is hard, not easy to crack fruit
7, other identification methods
Imported fruit labels. In general, the name of the exporting country is printed at the bottom of the label, the middle English letter indicates the name of the fruit, and the uppermost English letter identifies the name of the exporting company. In the middle of each tag, there are usually four digits of Arabic numerals: The word at the beginning of the three words indicates that pesticides have been sprayed. The words at the beginning of the 4 words are genetically modified fruits; the words at the beginning of the 5 words are hybrid fruits.
(1) When supermarkets purchase food, they must take care to check if there are genetically modified annotations. According to the "Administrative Measures on the Labeling of Agricultural Genetically Modified Organisms," genetically modified foods should be marked. But these annotations are scary to see people, as small as only 1.8 mm high, and hiding in the most inconspicuous place, careful investigation can always be found.
(2) Supermarket tomatoes and papayas are mostly genetically modified and can never be bought. In terms of safety and quality, individual farmers’ fruits and foods are much better than supermarkets. In particular, don't be fooled by foreign supermarkets. The things there are good and not delicious, bad and fake too much.
(3) The earliest, most extensive, and most used genetically modified corn should be used with caution when buying any kind of corn food, even if corn is sold in supermarkets.
(4) Transgenic wheat kernels are white, transparent and shiny, full-horned, and are hard, strong, high-quality, bread wheat varieties. The excellent transgenic 9506 wheat is available in Anhui in 2008. There is bleach and talc in the flour, making it even harder. Identification.
(5) Rice genetically modified in China has been secretly engaged for several years, and a small number of people have entered the market. Special attention should be paid to the long, thin and bright rice. Northeast rice is currently not genetically modified and can be rest assured for a certain time. We must look at the outer packaging bags, such as the rice industry in Heilongjiang, Jilin, and Liaoning. The northeast rice is glutinous rice and short-circle-grain type, which is related to the GM rice (such as BT) planted in Hubei and Hunan. Yingyou 63) has a fundamental difference in long-grain type and is easy to identify. In addition, Thailand bans genetic modification and its rice has no problem.
(6) Millet, oats, buckwheat, and sorghum are all small food crops. It is too late for genetic modification. Peanut is a unique product of our country. There is no genetic modification and sweet potato has not been genetically modified.
As
the name suggests, diaphragm metering pump using a special design and
processing of flexible diaphragm instead of the piston, under the action
of the drive mechanism to achieve reciprocating motion, complete the
suction - discharge process. Due
to the segregation of the diaphragm, the isolation between the metering
fluid and the driving lubrication mechanism is realized in the
structure. High-tech structural design and the selection of new materials has
greatly improved the service life of the diaphragm, coupled with
excellent corrosion resistance of composite materials, diaphragm
metering pumps become the main application of fluid measurement pump
type.
In
the diaphragm-type metering pump family members, the hydraulic
diaphragm metering pump as a result of the use of hydraulic oil evenly
drive the diaphragm, to overcome the mechanical direct drive mode under
the pump diaphragm too concentrated shortcomings, to enhance the
diaphragm life and working pressure ceiling. In
order to overcome the single diaphragm metering pump may occur due to
damage caused by the diaphragm damage, and some metering pumps equipped
with a diaphragm breakage sensor to achieve the diaphragm when the
automatic chain protection; with double diaphragm structure of the pump
head to further improve its safety Sex, suitable for security protection is particularly sensitive to the application.
As a kind of diaphragm type metering pump, the electromagnetic driven
metering pump generates the pulsating driving force with the
electromagnet, which saves the motor and the speed change mechanism,
makes the system compact and compact, it is an important branch of the
small range low pressure metering pump.
Precision metering pump technology has been very mature, the fluid metering capacity of up to 0-100,000l / h, working pressure up to 4000bar, the scope of work covers all areas of industrial production requirements.
