Blending Fruit - Keeping it Kosher Clips

I know that when it comes to blending fruit, that  there might be different halachos or a different   set of guidance. What's the difference  between blending and eating things raw? So I think in order to answer your question, we  should probably take a step back. When dealing   with levels of infestation, right? We go what's  referred to as "Acharei Rabbim Lehatos," we go   after the majority, right? So if an item, the  majority of the time, is clean, it doesn't   have any bugs on it, on a Torah level, there's no  obligation to check. However, Chazal have a fence,   a gezer, to help us keep the Torah properly. So,  there's a thing called "Miut Hamatzoy," where it's   a "Miut," it's a minority of the time, however,  it's still "Matzoy," it's still found. So,   30% of the time, or what have you. So in that  instance, there's still an obligation to check on   a rabbinic level. But something that's even less  common, very rare, we refer to as "Miut Sheaino   Matzoy," which is a minority of the time, which  is "Aino Matzoy," it's not really found at all,   very rare. Rav Belsky said you'd have  to be surprised to find an insect.   So you have "Miut Sheaino Matzoy," which there's  no obligation to check, it'd be very rare to find.   Let's say you find a bug in a banana, right?  There's "Miut Hamatzoy," which we'll throw in,   let's say, something like romaine lettuce, where  there's a rabbinic obligation to check. And then   something which is majority the time infested, to  eat it without checking would be a De'Oraisa, from   the Torah itself, because we assume that there  are bugs there. So, you have these three levels.   I say that Chazal didn't give four categories.  They gave three. I don't think there's a fourth   category where there's no bugs in anything ever.  Like, I even got a consumer inquiry once where a   consumer found a bug in a seltzer bottle, and  he called the OU to complain about it, right? It's like the study that the average  person swallows like four spiders a year. I think that was like a snap  fun Snapple fact or something,   right? Yeah. Yeah. Seven spiders.  That's what it was. Yeah. In any event, so number one is: what are the  levels of infestation? Now, when it comes to   blending, so we have another concept in halacha  called "Sfek Sfeika," where it's a double question   if something happened. So, in certain instances,  a "Sfek Sfeika" could permit something. So the   Rashba brings down, what happens if I took  something which is a "Miut Hamatzoy," which   the minority of the time would have bugs, not  majority of the time, only a minority of the time,   and then I went ahead and I blended it? So I  have here a classic case of a "Sfek Sfeika." And   it goes like this. Maybe there were no bugs. And  even if there were bugs, maybe they got ground up. And now they're mixed in like a chulent. Right. And if the bugs are accidentally  ground up, don't do this on purpose,   but if they were ground up, so the  reason why they wouldn't be nullified   in something is because something which  is a whole entity has a chashivus to it,   has a prominence associated with it. So you can't  say that it's nullified. But if it's in pieces,   it loses that status, and then it could  be nullified essentially. So over here,   in this instance, if it's ground up,  then you could say maybe it's nullified. So based on what you're saying, if you have  kale and you want to make a smoothie out of it,   and you see on this kale that there are  bugs, then blending is not going to help you. Right. Because essentially, what you only  have is one safek. "Maybe I ground up all   the bugs or not." The question with regard  to whether or not you could take something   which is minority of the time infested  and ideally, lechatchila, go ahead and   put it in a blender. That's something that the  person should ask their personal rabbi about. So, you're waiting for your plane and there's a   place that makes smoothies. Can you  go and just say, "I want some mango,   and I want some apple juice, and I want some  kale," and then get that kind of smoothie? That would not be recommended for a lot of  reasons aside from the bug issue we just   mentioned. Let's say it's a store chain,  and they want all the chain's consumers to   have the same experience. They actually have a  lot of ingredients other than just the fruits:   flavor inhibitors, flavor enhancers, and  so on and so forth. Sometimes these places,   they're full service, and they just  don't do juices. So there's just a   lot of reasons why it would definitely not  be recommended to do something like that.
