I- Food IrradiationA- History of Food Irradiation: Before 100 years, the process of food irradiation was discovered, however, it was considered as a safe way to process food in the second half of the last century. . Also, the first half of the 20th century was called the era of inventors, this name was given because at that time the facilities were not capable of implementing the process of food irradiation. This has been attributed to the lack of advanced technological capabilities. B- Negative impact of food irradiation: The food irradiation process can produce chemicals that cause harmful tumors. Another disadvantage of food irradiation is that it decreases nutritional value and causes kidney and chromosomal damage. Additionally, food irradiation will leave behind radiation-resistant bacteria that will multiply and food irradiation will eventually become ineffective. Irradiation doses destroy the bacteria responsible for viruses, botulism and prions. Irradiated foods not only cause health problems, but their factories produce toxic waste that causes chronic illnesses on the job. This problem adds to the already radioactive waste that is destroying our atmosphere and causing global warming. C- Positive impact of food irradiation: One of the few positive impacts is that irradiated foods can be kept fresh for longer, making food transportation take longer. food is easier to travel greater distances in remote areas. Additionally, the change in taste and texture of irradiated foods is insignificant. Other solutions should be found to avoid its negative impacts.II-Other alternative solutions:A-Freezing:Freezing is one of the oldest ways of preserving food. Early humans discovered that cooling food could prevent it from spoiling. Nowadays, fr...... middle of paper ...... to dry the water in food to make it last longer. Food dehydration involves removing water molecules or moisture from food, which prevents bacteria from growing. Between 80 and 90 percent of the moisture is removed from fruits and vegetables. So dehydrated foods weigh less than undried foods for example 20 pounds of apples are reduced to 2 pounds if dried as well as beets. It is useful for hiking, camping and backpacking. There are three methods of dehydration. The first is to expose food directly to the sun on a hot day of 30 degrees Celsius. The second method is to place the food in the oven and let it dry until it is dry, but this method is not safe in homes due to the presence of children. Last but not least, using a food dehydrator which is an electric dehydrator takes less time to dry the food and is more efficient than the oven..
