For our health it is important store food in the correct way, which does not only mean respecting the expiry date of the various foods. For a good one food storage it is necessary to follow basic common sense rules and other less obvious ones concerning the containers in which food is stored, refrigerators and freezers, up to the materials that make up the kitchen (which is usually the place where food is stored) and products that furnish it.
How to store food? Let's start with the things not to do and to pay attention to. The adherent films may contain the DEHA plasticizer which can be absorbed when it comes into contact with a hot food, or when the plasticizer itself heats up because it may be placed to cover a plate containing a hot food. Thermoplastic containers can also exhale gases and also in this case the risk increases with the temperature of the contents.
Insecticides and fungicides also contained in paints, upholstery and fly paper can come into contact with and be absorbed by food, while paper products may have been whitened and contain dioxin. Mold and bacteria found in porous surfaces and crevices can contaminate food. This would be enough to understand that store food so that it does not become something harmful to our health is not at all easy.
The pitfalls to food storage they are everywhere: foods not stored at a sufficiently low temperature can generate bacteria, those left uncovered can be contaminated by harmful insects. Raw foods that come into contact with cooked ones are dangerous to health (pay attention to the positions in the refrigerator), and the same goes for frozen and then refrozen. We add that residues of pesticides, hormones and preservatives are sources of pollution and given that some foods contain them, adding more would be too much.
Things to do to preserve food well. Prefer glass, ceramic and stainless steel containers to thermoplastic ones, even if they may appear less comfortable. Choose non-toxic papers and colors (which also means avoiding tea bags and paper coffee filters), use only natural preparations to keep insects away from the kitchen and set up mosquito nets or screens on the windows to prevent them from entering. Seal gaps and keep surfaces clean and dry.
Save the food in a clean pantry with detergents based on natural substances or in a cool and dry cellar, use the refrigerator the freezer for perishable products without forgetting that even frozen foods do not keep forever: the time is specified in the fridge and freezer instructions good conservation of the various types of food. Choose a good appliance, better if class A so you will save electricity and pollute less.
The quality of the kitchen environment affects the good food preservation. Regarding worktops, remember that the solvents contained in some laminates and plastic surfaces can give off toxic vapors. Better to opt for surfaces such as ceramic tiles, solid wood, stainless steel, slate, and marble or granite slabs.
For kitchen cabinets, keep in mind that plywood, chipboard, block plywood and other mixed-structure boards usually contain formaldehyde, which can contaminate food. Solid wood modular elements with traditional joints and glues made with natural substances are preferable. Metal cabinets don't hurt for keep food well.
