Researchers from Washington State University compared the usual strawberries and with the label "organic" and concluded that the first more flavorful, nutritious and leaves behind a healthy soil.
Researchers from Washington State University compared the usual strawberries and with the label “organic” and concluded that the first more flavorful, nutritious and leaves behind a healthy soil.
In the U.S. the label “Organic” labeled products grown using only natural fertilizers and without pesticides, herbicides, fumigants, or any other synthetic chemicals.
American study is one of the most ambitious in this area. It analyzes the 31 chemical and biological properties of soil, taste, nutritional value and quality of three varieties of strawberries from 13 normal and 13 “organic” fields of California, where it grows 90% of U.S. strawberries.
The results of the following: “organic” strawberry has a higher antioxidant activity, the concentration of ascorbic acid and phenolic compounds, it is kept longer and contains more dry matter, i.e. it is less watery. Tasters rated one sort of “organic” as a more delicious strawberries. In other varieties much of a difference they have not noticed.
The exclusive advantage of organic products is in maintaining the properties of the soil on which it grows. In the absence of a strong chemical exposure, the soil retains several key chemical and biological properties, including absorption of carbon dioxide, nitrogen and bacterial biomass, enzymes and trace elements. DNA analysis showed that “organic” soil is more unique genes and genetic diversity that is important for soil resistance to the adverse effects and the ability to maintain vital processes.
It should be noted that conventional farms use ozone-depleting fumigant methyl bromide, which replaced the previously used in the U.S. toxic methyl iodide. Inhalation of large amount of methyl iodide vapor causes lung, liver, kidneys and central nervous system, with serious chronic poisoning may occur even when exposure to low concentrations. At the post-Soviet space to buy methyl iodide is not difficult. But methyl bromide is not much better: in addition to the destruction of the ozone layer, it can cause endocrine diseases, irritation of the skin, eyes, respiratory tract, has a deleterious effect on reproductive ability, neurotoxicity. The use of these substances could affect the quality of strawberries. It should be noted that the time of their decay is measured by several days, so that the probability of poisoning by complying with the rules of processing plants is small. Nevertheless, in the same California Senator Dianne Feinstein (Dianne Feinstein) demands that the U.S. Agency for Environmental Protection to ban methyl bromide. Rather, it is a matter of time.
American study shows that a number of indicators strawberries, grown without chemicals, better than usual. Nevertheless, taste it often is not better, but price is higher, is also unknown whether the positive qualities apply “organics” to other cultures. A key question still remains the safety of chemicals used, because the hard work on the cultivation of organic products is unlikely to cover the needs of 6 billion people on the planet.
