How Healthy Are Chemically Treated Fruits? Effects of Preservation and Artificial Ripening

A modern nutrition and food supply world, the global fruit trade is of extraordinary significance. The wide variety of fresh fruits arriving from different parts of the world is not only delicious but also presents numerous challenges for the food industry. The transportation of fruits involves long journeys during which they must maintain their freshness, flavor, and nutrients.

These challenges are particularly important, as consumers expect fruits to preserve their original state as much as possible. The procedures and technologies used for storing and transporting fruits play a key role in maintaining quality and promoting safe consumption. To ensure the efficiency and safety of the food chain, many aspects of fruit handling must be considered.

The science behind preserving fruits is supported by serious research and development efforts aimed at minimally impacting natural flavors and nutrients. Knowledge of various storage methods and techniques is essential to keep fruits fresh for extended periods while consumers can enjoy the beauty and diversity of global fruits.

Cooling and Atmosphere Regulation

One of the most important factors in storing fruits is the proper regulation of temperature. Cooling is essential to maintain the quality of fruits, especially during long journeys. Fruits are typically stored at temperatures between 0-5 degrees Celsius, where physiological, chemical, and microbiological processes slow down. At this temperature, fruits can retain their freshness much longer, although each type of fruit requires a different optimal temperature.

It is important to consider that different fruits have varying storage needs. For example, for tropical fruits, too low a temperature can have detrimental effects, while for others, it is essential. When storing in a refrigerator, attention should also be paid to the placement of fruits, as storing different types together can affect their freshness. The black-skinned bananas seen in stores often indicate that storage conditions have not been properly managed.

Another innovative storage method is the use of controlled atmosphere, where fruits are kept in a low oxygen and high carbon dioxide environment. This method serves to slow down the respiration of the fruit, thus preserving quality and freshness. For example, the Williams pear, if harvested during the appropriate ripening period and stored under such conditions, can maintain its delicious and fresh state for up to three months.

Mycotoxins and Food Safety

Mycotoxins, toxic substances produced by molds, have long been part of the food chain and are a serious concern. These toxins can also affect fruits and cause various health problems if they enter the human or animal body. The effects of mycotoxins can vary, and different molds produce them under different conditions.

Eliminating them from the food chain is practically impossible, but everything must be done during fruit handling to reduce the amount of toxins. Proper storage and transportation methods, along with regular inspections of fruits, can help minimize the risk of mycotoxins. For food safety, it is important for consumers to be aware of the origin of fruits and the processing methods used.

In some cases, certain chemicals are also used during the preparation of fruits, such as post-harvest, to prevent mold and fungal diseases. These chemicals can remain on the surface of the fruits, raising concerns for consumers. Although the amount of chemicals is generally small, it is important for buyers to be aware of these procedures.

Chemical Procedures and Health Implications

The chemical procedures used in handling fruits, especially citrus fruits, have received serious criticism. Citrus fruits are susceptible to fungal diseases, so they are often treated with pesticides after harvesting. This treatment usually takes the form of a “bath,” which creates a protective layer on the surface of the fruits; however, this chemical can remain in the fruit’s skin and be difficult to remove.

While the purpose of chemical treatment is to protect fruits, it is important for consumers to know what is on their plates. Fruits that can be peeled, such as bananas, may not cause as much concern, but the presence of unwanted chemicals can be an issue when zesting lemon peels. Although the amount of chemicals is negligible, the awareness that we are consuming toxins, even in small quantities, worries many.

Another commonly used procedure is waxing, where fruits are coated with wax. This wax layer protects the fruit from moisture loss and external effects while also providing an aesthetic appearance. It is a material often used in the food industry, the effects of which are not harmful; however, it is important to know that in larger quantities, it can have a laxative effect.

Seasonal Fruit Selection

When buying fruits, it is worth considering the seasons, as different fruits are available at different times of the year. In winter, citrus fruits and tropical fruits dominate, while the selection expands as spring and summer approach. Thanks to modern ripening techniques, certain fruits like grapes are available in winter as well, but it is best to choose seasonal products.

Consuming fresh fruits seasonally not only provides a tastier experience but also is more sustainable. By purchasing local, seasonal fruits, we can reduce transportation costs and environmental impact while supporting local economies. Seasonal fruits are often fresher and more nutrient-dense, as they do not require long storage times.

Overall, the proper storage, handling, and purchasing of fruits play a key role in healthy eating. Conscious consumption and awareness can help ensure that fruits remain a source of nourishing and delicious enjoyment.
