Some previous studies have shown that certain ways of preparation can have influence on the carcinogenicity of food, as well as the method of preservation which can promote contamination or dangerous deteriorations. In particular, here we will consider laboratory studies, often lacking epidemiological data, when they are present have already been treated, such as the contamination meli attiki with aflatoxins. Production Pesticides and herbicides drugs for veterinary use genetic modifications Conclusions Storage Drying Fermentation Bottling and Canning Pasteurization Conservation Radiation chemistry Conclusions Conclusions Preparation Additives Packaging Food Processing Industrial Steam cooking, boiling and stewing cooking in the oven and roast cooking in the microwave frying and grilling Conclusions General conclusions meli attiki Production
However, there is an upper limit of acceptable residues in food, and is regulated at the international level, and the usage of many compounds (organochlorine compounds, furans, dioxins and polychlorinated biphenyls) will be banned from 2025, thanks to the agreements of the Stockholm Convention of 2004 .
In any case, the residues can, nowadays, be present in the food, and some of them may have the capacity to accumulate in adipose tissue, forming a potential risk over time. Although there are no epidemiological data to support the connection of these compounds and the development of cancer, the prudent behavior is always to be preferred, especially meli attiki in the case of pregnant women. Medicines for veterinary use
Unlike organic farms, factory farms make extensive use of drugs, especially antibiotics. This fact is mainly meli attiki caused meli attiki by the proximity of the animals with one another: confined spaces favoring the spread of disease and increase stress weakening the immune system of the animal. Furthermore it is possible that products are also used to promote the growth of the animal.
In most cases, however, the residues in food are below the maximum level, meli attiki and whether a drug has proven carcinogen meli attiki is withdrawn for use in breeding. Growth hormones are used in the USA, but the EU has banned them: many hormones may have a carcinogenic effect. Genetic modification
The crossings between plants have always existed and this has led to selecting varieties more similar to our needs. Currently, there are more advanced techniques meli attiki for the genetic meli attiki modification of plant foods, which can lead to crops more resistant or more nutrients. Not only can you insert a foreign gene into a plant, but you can think of to deactivate an existing one: for example, was made with tomatoes that currently, once accrued will soften more. There are no definitive studies on cancer risk given by this type of work, it is therefore impossible to give a judgment. Conclusions
Often it is a part of another type of storage (eg salting provides a drying step), but it is a technique used by always, since the human being has begun to store food. There is no evidence in this regard. Fermentation
Another very old way to preserve food, probably discovered by error due to an accidental contamination of bacteria or yeast. The main feature is that it changes the taste, texture and nutritional capacity of food. For example, with the fermentation, milk becomes yogurt, barley beer and becomes the grapes become wine. There is no evidence meli attiki in this regard. Canning and bottling
For these processes, we often caters also to the cooking of the food to be preserved, and can relate legumes, fruits, vegetables, meats and other foods. There is no evidence in this regard. Pasteurization
It is a process that concerns liquids, such as milk or fruit juices and prevents the multiplication of pathogenic bacteria. It consists in a rapid temperature rise followed by a rapid lowering of the same. There is no evidence in this regard. Chemical preservation
The additives preserve foods by preventing microbial growth and decay. They can be antimicrobials, antioxidants or enzyme inhibitors. The compounds most used are the benzoate, the sulfites and nitrites. For each type of additive there is a maximum limit defined by law. Radiation
In the early twentieth century radiation
