The safest choice for food storage is a container least affected by odor and staining; in that sense glass containers usually come first, since they do not hold smells, do not stain, and can go straight into the microwave. Still, each material has its own strengths and weak points, and the right pick depends on what you are storing.
What are the pros and cons of glass?
Glass keeps colorful, aromatic foods like tomato sauce or curry without staining or trapping odors; it can be used in the oven and microwave and is easy to clean. On the downside it is heavy, can break if dropped, and if a liquid-filled container is sealed completely full before freezing, the liquid expands as it freezes and can crack the glass.
When using glass, avoid filling it past two-thirds full, and let the contents cool completely before putting it in the freezer.
When is plastic the right choice?
Being light and unbreakable makes plastic practical for meals you carry around daily. Over time, though, plastic can be stained by colorful liquids like tomato sauce and can absorb odors from hot food. A container that is not labeled microwave-safe should not be used for reheating, and cracked or scratched containers should be replaced.
When should metal be preferred?
Stainless steel containers are a sturdy, lightweight option for dry goods such as crackers, nuts, and flour, and since they block light they also protect light-sensitive items. Acidic foods — tomato paste, pickles, citrus — can pick up a metallic taste after long contact with metal, so metal is not the right choice for acidic contents.
Are they dishwasher safe?
Glass and stainless steel wash fine in the dishwasher; high heat does not distort their shape. Plastic containers, if washed at high heat repeatedly, gradually turn cloudy and the lid gasket can lose its flexibility, so hand-washing plastic lids in warm water helps them last longer.
Over the long run, glass and stainless steel hold up better and need replacing less often, while plastic stays useful as a cheap, practical option for everyday carrying. The soundest approach is to keep all three materials on hand and use each where it performs best.
Which container suits which food?
As a rule of thumb, liquid and aromatic dishes do best in glass, dry legumes and grains in metal or glass, and everyday snacks you carry around in plastic for convenience. Never use a container with a worn, cracked, or loose-fitting lid seal — a leaking seal exposes the food to air and it spoils faster.
When switching containers, fully removing old labels and dating the new contents prevents mix-ups. Whatever material you choose, a tight lid and a dry container are what actually determine how long the food keeps.

Paslanmaz kapta sakladığım naneli turşu üç gün sonra metalik bir tat aldı, yazıdaki asidik gıda uyarısını okuyunca sebebini anladım, bundan sonra turşuyu cam kavanozda tutacağım.
Yıllardır plastik kap kullanıyordum, salça sosunun rengi hep kabı boyuyordu; cam kaba geçtikten sonra hem leke hem koku sorunu bitti, temizliği de çok daha kolay oldu.
Paslanmaz kapta iki gün bekleyen domates salçasının tadı gerçekten acımsı bir hal aldı, yazıda 'uzun süre temas ederse' diyor ama bence iki gün bile uzun sayılmaz, bu bilgi eksik anlatılmış.
Cam kabı üçte ikiden fazla doldurmayın demişsiniz ama ben tam dolu kapattığım kavanozu dondurucuya koyup hiç çatlatmadım, bence bu uyarı biraz abartılı, sadece çok sulu yemekler için geçerli olsa gerek.
