Silk - Soy Milk - Spoilage

Joe Berger Feb 18, 2010 07:33 AM

I'm kinda new to soy milk, but when a local grocer had them on a half price promotion, I bought a vanilla and a chocolate half gallon. they both had a 2 month good till use expiration. I open both of them up, tried them both, they seem OK, put them back in my very cold fridge.

2 weeks later the chocolate carton actually exploded inside my fridge!

stranger still is the vanilla one is perfectly fine and drinkable. it says on the carton that silk is only good for 7-10 days after opening, even though it has a 2 month good till use date.

this is all new to me, because when you buy regular lowfat milk, it matters little if you open the carton - it's always the "good till use date" that determines when regular milk is likely to turn soar on you when left inside your fridge. (yes, I'm sure breaking the seal matters by a few days - but please don't get distracted by that issue)

so I call Silk and ask them a simple question. is one flavor more likely to spoil faster than another, or was my chocolate spoiling a quality control issue. so they gave me the company line - once it's opened you are dead in a week or two - and no - flavor does not matter at all.

I'm left to ask all you health concerned folk here who presumably are more familiar with silk/soy milk consumption than I apparently was.

1. how long does YOUR soy milk stay drinkable after you first opened it.

2. did you notice a spoilage rate difference one brand or flavor over another.

thanks for your time considering this.

    Regular Silk lasts for months here... I prefer Almond Breeze and have some in the fridge to open next. I feel your pain, I have had Stonyfield yogurt explode in my fridge once, it was not pretty.

      We use West Soy, but I buy the shelf-stable packages. I imagine the Silk is from the Dairy section, yes? I wonder if that increases the rate of spoilage. I'd have to compare ingredients to see what sort of differences there are. I know I tried Silk and liked the West Soy a lot better.

      The West Soy we use stays fresh in the fridge for quite some time, 2 weeks at least, sometimes more. The nice thing is that I always have back-up containers in the pantry, so even if it does go bad, we don't have to run to the store. Maybe try some of the shelf-stable options and compare them to the Silk?

        Interesting...I've been using Silk Vanilla soy milk for about 7 years now and have never once had it go bad on me. I know there have been a number of times it has taken me over two weeks to use 1/2 gallon. I always shake it before pouring - but I don't know if that is relevant or not.

          I TOO had this problem and just never did anything about it! Sort of new to soy milk, I bought light vanilla Silk soymilk three different times. EVERY time, it "curdled" weeks before the expiration date. Got goopy or something. I just tossed it, and eventually quit buying it.

            You do need to shake the carton well before pouring and not just when you're down to the bottom. I had this problem the first time I bought any - got so thick it was barely flowable - but never since I discovered this.

            In regard to the OP - I've never had a spoilage problem that I've detected..

            I haven't noticed a difference in the rate of spoilage. We usually drink it too quickly to be concerned about it.

            What is the temperature of your refrigerator?

              I guess it's my mistake for thinking Silk would keep like Parmalat does.

              it just seems odd how one flavor stays good all month,
              while another flavor barely lasted the first week open.

                Did the boxes have the same packaging date?
