I saw Hemp as an ingredient is approved on the pesach list, but I am curious about the following:
Pacific Foods Unsweetened Hemp “Milk”: water, hulled hemp seed, contains 1% or less of: disodium phosphate, gellan gum, natural vanilla flavor with other natural flavors, tricalcium phosphate, vitamin d2, xanthan gum.
