Water separating from tomato sauce can result from natural tomato enzymes, water-rich varieties, or freeze-thaw changes and is often a quality issue; gas, mold, bad odor, or a swollen package are different problems.
Live insects, larvae, webbing, exit holes, or unexplained powder in nuts indicate a pantry-pest infestation; discard the affected package and inspect nearby dry foods rather than treating only the visible nuts.
Black or gray spots on tempeh are often normal Rhizopus spores from fermentation; unusual colors, slime, mushiness, or a strongly unpleasant odor point to a different problem.
A thin layer of oil or watery liquid can separate from hummus during storage and may be stirred back in, but refrigeration history, mold, gas, slime, and off odor matter more than separation alone.
Oil separation is normal in many natural peanut butters because they lack strong stabilizers; stir it back in unless the spread shows rancid odor, mold, contamination, or package damage.
Soft cereal often reflects absorbed humidity and a loss of quality; mold, rancid odor, wet clumps, stains, or insects indicate spoilage or infestation.
Salt usually cakes because it absorbs humidity and can still be used; dirt, insects, mold on contamination, or unusual odor are different problems.
Spontaneous bubbles, pressure, sour odor, slime, or increasing foam in refrigerated cooked legumes can signal fermentation or spoilage and call for disposal.
Spoiled tofu commonly develops a strong sour smell and slimy surface; mold, gas, abnormal colors, or poor refrigeration are additional reasons to discard it.
Softness can come from humidity, but sticky, stringy bread with abnormal fruity odor or discoloration can indicate bacterial rope spoilage and should be discarded.
Discard flour with weevils or larvae, inspect nearby dry foods, and clean shelves and cracks; sifting out visible insects does not reliably remove an infestation.
Discard dry rice with insects, inspect nearby pantry foods, and clean containers and cracks; cooking or removing visible adults does not reliably eliminate an infestation.
