when does this mayonnaise expire?
« on: February 21, 2022, 01:28:56 PM »
I bought some mayonnaise. This is the expiration date.

Is it Jan 8, or Aug 1?

If you bought it in the US, it's August 1.

If it was stored correctly and unopened, I'm sure it's fine for a while after the "best before". Otherwise I'd throw it out. Also what mayonnaise comes in a bag?

I bought it in the US, but it's a Japanese brand. It has the USDA nutrition facts, so it's labeled for sale in the US.

Yeah, that tells me the date is written per the US convention.

Mayonnaise comes packaged in plastic bags rather than jars in Japan? Learn something new every day.

Japan subscribes to YMD (Year, Month, Day) date conventions. The USA to MDY (Month Day Year). In both standards day comes after month so it's August 1st (and it's a perfect match to a Japanese style date).

So how much better is this mayonnaise brand than Hellmans/Best Foods? I remember living in Japan as a little kid and I still remember how great hamburgers were at a place we used to go to where they spread mayonnaise on the bun, something my mom never did. I've always wondered if that was some weird nostalgic memory or if the mayonnaise was really good there.

Not OP, but I can answer that Kewpie mayonnaise is freaking amazing. We buy exclusively Kewpie or Duke's depending on what is easier for us to get at the time. Kewpie is soooo much better than Hellmann's. Which has always been weird to me because I think of mayo as dairy almost like cheese.

Eta: Duke’s is not Japanese, just to clarify.

OP here. The brand I bought is Kewpie. I haven't tried it yet. But I heard lots of testimonies like Kris, above.

Apparently there are two kinds: the kind from Japan that is made with MSG, and the kind that is made for Americans that has yeast extract instead of MSG. MSG is a fountain of umami goodness so that's the one I bought.

Where did you find it? That sounds amazing, but buying mayo online seems like a recipe for receiving a spoiled gross mess that's been transported in freezing airplanes and searing  hot trucks before it got to my house.

So, again, sorry, I’m not OP (can you tell I feel strongly about this mayonnaise?) but just like any other mayo, it is not a refrigerated product. We get it off the shelf from Asian stores around here, but you can buy it from Amazon. I’m sure it’s fine to do that.

Here's the one I bought.

I haven't tried it yet because it just arrived today. I'll try it on something tomorrow.

That's international standards date format (ISO). Year, month, day. So you're safe until the 1st of August 2022.

On the second of August however...

Typically, most companies adhere to the same date labeling practices except where required by local or regional requirements - working in the food industry, that's almost definitely August.

Moreover, products for sale in the US which are labeled as "Best Before" aren't unsafe to eat after the date listed - "BB" just has to do with the quality declining beyond what the manufacturer deems to be reasonable. So if you go call the company hotline on August 2, they're going to politely tell you to buzz off because it tastes funky. That's not to say that the product would be edible indefinitely, but that's the extent of the product shelf life based on the ingredients, process, packaging, and storage conditions. Given that it's mayo, eventually it's going to spoil in the packaging, but even if that date was January, as long as it wasn't funky or separated I'd expect you'd be perfectly fine to consume it for some time.

Conversely, if it's labeled as "Sell By" or "Use By", those dates do have to do with the safety of consumption (at least under reasonable consumption conditions). Like "BB", the "Use By" date listed isn't some magical threshold where the product is instantly bad, instead it's the amount of time lapsed where the manufacturer expects a significant number of products will have begun to spoil.

Another vote for Kewpie as the best mayo around. And, for the uninitiated, there is a soft plastic bottle inside of the bag. There's a lot of debate out there on what ingredient gives it its particular depth of flavor-- malt vinegar and dashi powder seem to be the leading contenders.

They also apparently only use the yolk of the egg instead of the egg and egg white. I imagine that makes a difference.
