If you are concerned that your soymilk is spoiled, we recommend that you not drink it. Some signs that your soymilk may have “gone bad” are: unusual smell, taste or color to your soymilk, a bloated container, a puncture or cut on the carton, soymilk that has gone past the expiration date printed on the top, or soymilk that doesn’t pour out smoothly or has turned “lumpy”.
