Question

why plant based milk can be stored for almost a year but once opened has to be consumed within 7 days?

Answer 1

This isn’t specific to plant-based milks but all milks (and other foods too) that have been sterilized at high temperatures. Once you open the package it is no longer sterile, and any microorganisms that have gotten in can then start spoiling the product.
