![]() ![]() When freezing foods, use materials that are safe for freezing and containing foods, such as plastic freezer containers, freezer paper, non-sticking freezer foil, or freezer bags. ![]() Therefore, keep items in refrigerator freezers for a month or two while free-standing freezers can keep foods protected for up to 12 months. This leakage of air may cause food items to grow ice crystals as moisture forms from temperatures variations. The refrigerator freezer is opened and closed often, affecting the amount of air leaking out, thus warming and refreezing contents. Be aware of the difference between the refrigerator freezer and a free-standing freezer. Freezing a food will not guarantee that it can be kept forever, since there are too many variables affecting the quality of the food prior and during freezing. Freezing a food and keeping it frozen will eliminate the opportunity for food borne illnesses to occur, since the pathogens that adversely affect food cannot grow. Keep in mind that the faster an item can freeze, the better it is for preserving the quality of the food item. Typically, items such as meat, poultry or fish will freeze in several hours. Solid items such as food also experience similar results, freezing at different lengths of time or temperatures based on their substance and chemical composition. ![]() Thus, various liquid substances freeze at different temperatures based on their chemical composition. Impurities, minerals and miscellaneous substances in water (such as salt or alcohol) change the temperature or length of time required to freeze water. The temperature at which pure water freezes is 32º Fahrenheit or 0º Celsius. The process of lowering the temperature of a liquid or solid to its freezing point. ![]()
