Ideas
With the evolution of the times, the development of science and technology, and the progress of civilization, people are not concerned about whether they have enough to eat, but what is healthy and unhealthy? Is nutrition balanced? Due to the advancement of technology, the mass production of agricultural livestock is automated, and a large number of synthetic compounds are applied in daily foods such as pesticides, fertilizers, antibiotics, clenbuterol and ..etc.Endless stream of food safety incidents are also heard everyday. How to eat healthy and eat peace of mind is a topic that everyone cares about nowadays. However, the public can not afford to paytoo much price for the inspection fees, they can not detect everything they buy from the market, theycan only "trust" the merchant's conscience and their own luck.

In view of this, Jasmat Optics has specially developed the VC10s, a pesticide residues and nitrate residue detector in vegetable, which can quickly check whether there are pesticide residues and nitrate residue in vegetables! It’s simple, convenient, fast and reliable to use VC10s. Jasmat believes that the VC10s can bring you a healthier life. Jasmat will continue to work hard anddevelop more products in other food safety and makes the world better!
 
Types of pesticide residue
General speaking, pesticides residue on vegetables are defined as surface type and systemic type. Surface type refers to the pesticide that is sprayed on the surface of a plant, acting directly on the surface or absorbed by the surface. Systemic type refers to the pesticide that is absorbed through the roots of plants and transferred to whole plant. The surface type residue can be partially removed by washing or degraded by light.Systemic type residues cannot be removed by washing, some residueswill be partially degraded slowly for a period of time by placing it in a ventilated place.

It is relatively easy to remove surfacetype pesticide residues. Generally speaking, it can be removed by washing with a large amount of water before cooking. It is relatively difficult to remove the systemic pesticide residues. Therefore, VC10s is designed for rapid detection of systemic pesticide residues.

 
Indicators
Numerical judgment: VC10s is designed for rapid detection of systemic pesticide residues and nitrate in vegetables. It is based on the concept to detect total quantity.The results are defined as 5 levels:
 
Technical principle and Jasmat patent
VC10s - is a vegetable pesticide residue and nitrate residue detector developed by Jasmat. It applies the principle of optical and electrical composite detection technology to detect systemic pesticide residues in vegetables. The basic concept is that most pesticides have unique absorption and excitation peaks in specific spectra,they also have unique electrical physical phenomena in electro-chemistry, which can be regarded as characteristic values. By modeling these eigenvalues as database, we can use AI ​​component to recognize whether there is any pesticide residues and analyze residual values.
 
Although the above physical principle sounds simple, it is necessary to overcome some technical problems practically, for example, the signal extraction may be interfered with some noises. So we developed a new type of optical and electrical composite detector to enhance signal acquisition. For the characterization data, we tested a variety of vegetables from different origins, and created data one by one. When using VC10s to detect pesticide residues in vegetables, first step is to insert the probe into the vegetables.Second,AI will collectand process the signals of trace residual pesticide distributed in the vegetables.Finally the AI processor will analyze the extent of pesticide residues.
 
Throughout the development of VC10s, we applied for multinational patents to protect our intellectual property rights and this also protects consumers who use VC10s. Each VC10s shipped from our factoryis 100% calibrated and qualified.
 
 
Description of the steps
 
Leafy growth principle
● The characteristics of leafy vegetables are that they grows upward from the soil, while the absorption of nutrients is transported upward from the soil.
● This type of vegetable is detected by inserting the probe into the xylem of the root.
The same cross-section can't be repeat detected】
 
Root and stem growth principle
● The characteristics of root vegetables are that they grows downward to the soil, while the absorption of nutrients is transported downward from the soil.
● This type of vegetable is detected by inserting the probe into the xylem of the glans.
The same cross-section can't be repeat detected】
 
Functions
● Power / Measurement button:
     – After a short press, VC10s will automatically wake up and start measuring.
     – When VC10s is idle for about 30 sec, it will automatically enter sleep mode, and VC10s can be operated again after a short press.
● Power indicator:
     – When VC10s is turned on normallythe indicator light is always on.
     – When the power indicator is blinking,the battery power is low. Please replace battery as soon as possible.
     – The battery life cycles are approximately 1500 times.(The actual times will be increased or decreased depending on battery conditions)
● Calibration indicator:
     – When the calibration indicator lights on, it means that system is ready.
     – Please close the probe cap and press the measurement button to calibrate VC10s before each measurement.
     – If the system can’t be ready after calibration. please clean the probe.
● Measuring probe:
     – Optical and electrical composite probes.
     – Lifetime is around 3,000 times.(If probe can’t be calibrated after clean many times. Then the probe can’t work any more).
● Probe cap:
     – When VC10s isn't in use, please cover the probe to avoid damage.
● Battery cover:
     – Two replaceable batteries(model: AAA).

Q&A of VC10s

General speaking, pesticides residues and nitrate residues need to be extracted before detection. This is not easy to doit for home use. VC10s is designed to be simple, fast and accurate so that users can know what extent the pesticides residues and nitrate residuesare in vegetables. We use innovative optical-electrical composite methods, as well as AI artificial intelligence technology, to calculate the residual probability for both systemic pesticides residues and nitrate residues. Therefore, userswill know how much the residual amount of pesticide residues and nitrate residue will stay in the vegetables within one minute without any extraction. For users, it is only necessary to know which lightmeans“OK” and which lightmeans“not OK”. It’s very easy to get started with VC10s, and users do not need to know chemistry at all orprofessional training of extraction.
VC10s can detect systemic pesticides residues and nitrate residues in vegetables.Both residues are counted together. As for the detection of residues in fruits, tea or other crops, it’s not available now.
VC10s can detect systemic pesticides residues in vegetables. When pesticides are classified according to the route of application, they can be classified into surface type and systemic type. Surface-type pesticides: Refers to pesticides that are sprayed on the surface of plants and act directly on the surface or absorbed through the surface. Systematic pesticide: refers to pesticides that are absorbed through the roots of plants and transferred to the whole body of plant.
Because the action of systemic pesticides is mainly through the absorption of roots or pedicles into the body of the vegetables, the residues in the roots will be higher than other parts of the vegetables so the root or the pedicle is the best position for detection. Because of the different ways in which vegetables grow, it is recommended to test the roots of leafy vegetables such as Chinese cabbage, Bok Coy…etc. The root vegetables are recommended to test its pedicle, such as carrots,pumpkin…etc.
Since we are using innovative optical-electronical composite detection technology and AI artificial intelligence algorithm, we need to collect and process astronomical data of characteristics. VC10s is the first generation of our products, and its characteristic data is from vegetables. In addition, the characteristic data of aqueous solution, fruit, tea or other non-vegetables is completely different. Although we can obtain the data from detection of non-vegetables, the resultdoesn’t mean anything.
VC10s usesinnovative optical-electronical composite detection technology to detect the residues in vegetables. Since the residues inside of vegetables are trace level physically, the electrode will adsorb residues when the probe is operating, which will affect the surface distribution within a certain range. Therefore, we suggest that each cut surface can be tested only once, thus the results of such condition will be close to the natural distribution.
Generally speaking, pesticide residues and nitrate residues are unevenly distributed in vegetables. It’s possible that we will have different results in different cut surface. Furthermore, the results might vary due to environmental differences during detecting, incorrect operation,repeatedly detections of one place, because of the residues inside of vegetables are trace level physically.
The five lights on VC10s represent different residual rates, indicating the probability of pesticide residues and nitrate residues in vegetables. The higher residual concentration is, the higher residues being detected by VC10s. on the contrary, the lower residual concentration is, the safer it will be. Basically, green and yellow lights are acceptable.
Because VC10s is designed to be simple, fast and accurate so that users can know what extent the pesticides residues and nitrate residuesare in vegetables. We don't want too much pre-treatment (homogenization, extraction) for the user to operate.Just a simple button for the user to operate, the he will know which light means OK, or which light means not OK. We are pursuing such simple and understandable products, so we use some methods in mathematics: multi-sampling, majority decision to achieve the above pre-processing purposes. The more samples you test, the closer it is to the real situation (the concept of multi-sampling is similar to the pretreating homogenization action, and the concept of majority decision is the extraction action on the pre-treatment).
VC10s is designed according to the concept of semi-quantitative, not by qualitative or quantitative. This is because VC10s uses AI artificial intelligence computing technology to estimate the possible residual probability in vegetables. Generally speaking, the higher the residual concentration is,the higherprobability it will be detected. According to the result comparison with standard laboratory, it can be achieved up to the ~0.1ppm level.
The probe needs to be cleaned after each test. The cleaning method :please use alcohol cotton sheets, or cotton dipped in pure water, gently wipe, the lifetime of the probe is around 3,000 times (according to the conditions of usage, it will be increased or decreased ) If the light of OK cannot be on after multiple cleanings, the probe cannot be used any longer.
Each VC10s will be calibrated before shipping out, so the probe cannot be replaced.
Waterproof is not available now for this type, please avoid soak VC10s in water when cleaning the probe.
When the result is red light, it means that pesticide residues or nitrate residues inside of the vegetablesare too high. Because VC10s works as counting the total amount of both residues, it is impossible to distinguish which one is high, when one of the residues is high. It will turn red when it is lit. Basically these two residues are unhealthy for the human body. When the residues are detected too high, sometimes the vegetables can be temporarily placed in the ventilated place for a period of time to let the residues degrade naturally, but this might not be useful for some type of residues, so next time you can buy vegetables from other good stores.
Precautions
