Can fruit and vegetable washing machines really wash fruits and vegetables? This is a question of many people.
Today, fruits and vegetables residues, preservatives, edible wax and other widely used, fruit and vegetable washing machine has increasingly become a necessary choice for many families. Many people go to the Internet to collect a variety of fruit and vegetable washing machine, also on Baidu to ask "fruit and vegetable washing machine really useful" this question. However, I believe that the vast majority of people still do not know whether the fruit and vegetable washing machine is useful or not, there will be a variety of scruples and doubts about the efficacy of the fruit and vegetable washing machine.
What is a fruit and vegetable washing machine?
As the name suggests, it is a machine for cleaning fruits and vegetables. But the cleaning here is not to wash the dirt on vegetables, but to wash away those fruits and vegetables that can not be washed away by water residues, bacteria residues and so on. Many people also have questions from this, everyone is convinced that "seeing is believing", but the fruit and vegetable washer on the bacterial residues, pesticide residues are invisible to the naked eye, so it is impossible to judge whether there is efficacy. So many people will ask, is fruit and vegetable washing machine really useful?
At present, there are three kinds of fruit and vegetable washing machines on the market in China: ultrasonic fruit and vegetable washing machine, oxygen fruit and vegetable washing machine, ultrasonic + oxygen combination fruit and vegetable washing machine. Through the introduction of the following three types of fruit and vegetable washing machine, I believe you can answer the question of whether the fruit and vegetable washing machine is useful.
Is fruit and vegetable washing machine really useful? Ultrasound fruit and vegetable cleaning machine mainly uses the high frequency vibration of ultrasound, produces a large number of tiny bubbles, enlarges and closes the bubbles to form negative pressure, to remove the dirt and impurities on the surface of the peel. But the defects of ultrasonic fruit and vegetable cleaning machine are very obvious, and the adhesion of pesticides, wax, heavy metals and other fruits is poor. There are quite a number of ultrasonic fruit and vegetable washing machine in order to play a better role, will be matched (many enterprises claim to be herbal deoiling) washing powder, in fact, are decontamination of chemical products, and rely on chemical products to play the effect of removing agricultural residues, in fact, produced secondary pollution.
Active oxygen fruit and vegetable washing machine mainly uses the natural sterilization and disinfection function of active oxygen to realize the sterilization and disinfection of fruits and the removal of agricultural residues. Many people don't know about living oxygen. Actually, living oxygen is always around us. After lightning, the air is fresh because lightning releases a lot of ozone. In the dense forest environment, the concentration of living oxygen is also high. So far, oxygen is the only additive that can be approved for direct contact with food in Europe and America. Therefore, the efficiency of the active oxygen and fruit and vegetable machine is the highest.
Ultrasound + live oxygen fruit and vegetable washing machine, the advantages are full-featured, automation, liberation of people's hands, the disadvantages are high prices, large area (need to have a large kitchen), because no hand involvement, working hours in more than 15-20 minutes, a considerable part of the fruit and vegetable washing machine in order to play a clean effect, will add washing Flour and food also face two pollution problems.
Therefore, it is not the more expensive fruit and vegetable washing machine, the better the actual effect, the key is still to see a family's comprehensive consideration: kitchen area, pollution eradication, removal of high efficiency residues. Horizontal comparison, or oxygen and fruit and vegetable washing machine is more practical.
