Strawberry pesticide residue is not high? Pesticide residue detector test will know
Spring is the season when a lot of strawberries are listed. Whether it is a fruit shop or a street, there are more strawberries to sell. Red-brown strawberries vary in form, with a full, petite and mellow color; red, red, and purple. Many citizens who love strawberries are also worried about the pesticide residue of strawberries when they buy strawberries. To determine whether these strawberry pesticide residues are high or not, the method is actually very simple, and it only needs to be known by using a pesticide residue detector.
Strawberry pesticide residue depends on the speed of decomposition of pesticides and the interval between the last application and picking. If the pesticide residue in strawberries exceeds the standard, it will have an impact on human health. In order to ensure the safety of strawberries, generally speaking, the regular Supermarkets and large production bases have strict control over the time of picking and listing. Before picking, they will also use professional pesticide residue detectors to detect and ensure that the strawberries they buy are safe.
The detection method adopted by the Pesticide Residue Detector is a rapid detection method, which belongs to the first screening, rapid detection of organophosphorus and carbamate pesticide residues in fruits and vegetables, which can be quickly used to detect pesticide residues in strawberries. The test results determine whether the pesticide residue in strawberry exceeds the standard. When the inhibitory rate of the strawberry sample extract on the enzyme is 40%-50%, it indicates that the sample to be tested is a suspected pesticide residue exceeding the standard sample; when the inhibition rate is 50%, it means that the strawberry There were high doses of organophosphorus or carbamate pesticides and the samples tested positive.
With the continuous improvement of people’s awareness of food safety and the rapid detection of pesticide residue detectors, companies and individuals can use pesticide residue detectors to measure the fruits of strawberries and other fruits during the strawberry cultivation and sales process. Residues, so the safety of fruits and vegetables is more guaranteed, but the citizens buy strawberries, it is recommended that you go to regular supermarkets to buy, because the large production base on the picking, the time to market is strictly controlled, pesticide residues will be within the safety standards .
Steel Bar Straightening And Cutting Machine
Details of steel bar straightening machine
Easy to disassemble, easy to carry and install, and equipped with digital control device, which can be positioned according to customers' different requirements, quantity and length.
Straightening speed, cutting is correct, no noise, no cut, adjustable straight Φ 4-14 plates reinforced with Φ Φ level 4 - Φ 12 reinforced bar, suitable for all kinds of construction site and reinforcing steel bar processing.
Product features of steel bar straightening machine
There are automatic steel cutting machine and semi-automatic steel cutting machine.
Automatic cutting machine is also called electric cutting machine, which is converted from electric power through motor to kinetic energy to control cutting knife incision to achieve the effect of shearing steel.
While semi-automatic is manual control of the incision, so shear reinforcement operations.
And at present more should belong to hydraulic steel bar cutting machine.
Hydraulic steel bar cutting machine is divided into two categories: charging type and portable type.
1. Microcomputer control, automatic straightening and automatic cutting.
2. Simple operation and simple use.
