Perfect Bar Unwrapped: Understanding The Fridge Behind The Refrigerated Protein Bar

As the makers of the Original Refrigerated Protein Bar, we have faced one question over and over again: “Wait, you’re stored in the fridge? Why?” Simply put it is because the fresh nature of our bars – I mean, real food is kept cold, right? Think fruits and vegetables. The best bite of an apple is one that is crisp and fresh from the fridge. Our bars are similar – they are best fresh from the fridge. But, don’t worry if you need to take yours with you — our bars are good for a week at room temp!

Let’s dig a little deeper about the refrigeration thing and get a better understanding of why it is we chose to toss our nut butter protein bars in the fridge and forgo the shelf-stable option like many other protein bars.

It’s Cool To Be Chilled – The Why Behind The Original Refrigerated Protein Bar

One of the main reasons why Perfect Bar is a refrigerated protein bar is because we don’t use chemical preservatives or emulsifiers to create our bars, therefore refrigeration is required. What does this mean exactly? Though there are all types of natural food preservation – sugar, salt, smoke – that have existed for centuries, our food system in the modern-age has developed tactics that distorts or perverts food in ways that can make it stable to sit on a shelf without natural forms of preservations for months or even years without changing its make up.

Though in extreme environments or cases, this may be a viable option – think storm shelters or things of this variation. But for us, and those who want to add positive nutrition and whole food protein to our lives in healthy, quality ways, eating something that has sat on a shelf collecting dust for months at a time isn’t something that was particularly of interest to us when formulating the original Perfect Bar recipe.

So, we turned to tactics of old and found two, in particular, that made sense to us nutritionally and aligned with our core company values — the cold and organic honey. Refrigeration, then, was a natural preservation of the high-quality ingredients, always gluten free, soy free and Non-GMO Project Verified, and one that has remained central to our brand. This requirement stems from the need for our bars to stay at their optimal consistency, freshness and maintain the flavor you know and love.

Let’s rewind and take a look at the history of refrigeration, after all, it is one of natures oldest preservatives as our Founder, Bill Keith says.

Refrigeration In Review: A Quick Recap Of The History of Refrigeration

Refrigeration was invented back in 1748 by William Cullen but was never fully executed or demonstrated. It wasn’t until 1844 when a US physician named John Gorrie built a refrigerator, based off of Oliver Evans design, with the sole purpose of producing ice for cooling air for yellow fever patients. It wasn’t until later in 1857 that the first ice making machine was invented for food purposes, such as storing meat and brewing by James Harrison.

Before both refrigeration and freezing were invented, people were using “refrigeration” to keep their meat fresh and other products but it was done in a very make-shift way using snow or ice found in the mountains. The first known “refrigerators or freezers” if you will, were simply holes dug in the ground and filled with ice and snow and would typically last a week. It’s safe to say that refrigeration has been around longer than you would expect and is one of the oldest ways to preserve fresh food.


Fast forward to today, the trend of fresh food and fresh snacking is continuing to grow as consumers are becoming increasingly aware of what is going in their food and what they are putting in their bodies.

A Refrigerated Protein Bar With No Chemical Preservatives, Just Honey

The core reason the Keith Family turned to honey when formulating the original Perfect Bar recipe nearly 18 years ago was for its sweetness. Honey was always around the Keith household growing up. Leigh Keith, Co-Founder of Perfect Bar, tells us that her mom still keeps a 5-gallon bucket of honey around the house. Honey, a naturally derived sugar, is slow-burning, causing a lower and slower rise in blood sugar which pairs perfectly ( if we do say so ourselves) with all the good-for-you fats in our bars, like nut butters and oils, and keeps them working in cohesion.

Which brings us to the second and equally important reason why the Keiths chose honey — to act as a binder for the blend of whole food ingredients. The mixture of dried fruits, vegetables and freshly ground nut butter made for a delicious and nutritious protein bar but was in need of something to hold it all together. That’s where honey comes in. It acts as both a sweetener and a binder working in conjunction with the cold of the refrigeration, which spares our refrigerated protein bars from needing any preservatives or emulsifiers. So without honey, Perfect Bar would quite literally fall apart and not be that creamy, cookie-dough texture our fans love so much.

This Refrigerated Protein Bar Is Ready For Life On The Go


Perfect Bar protein bars are never heated like most of the other protein, snack or nutrition bars. Our bars are hand-crafted then go straight into the fridge where they can maintain its shape and optimal texture until they get shipped to happy households and retail partners across the country.

If it weren’t for refrigeration, Perfect Bar would not be where it is today. Refrigeration is required to maintain the best and most consistent tasting protein bar but not to worry, our bars are good for one week out of the fridge and on the go at room temperature. What this means is that we make for the perfect go-to snack whether you’re going on a road trip, to work or just hanging around the house, we’re there for you.

  1. Just tried my first bar and it’s delicious!!
    While reading about your bars I couldn’t help but, notice this spelling error and thought you may want to fix it. 🙂 🙂

    (I think you meant “nameD John Gorrie)

    It wasn’t until 1844 when a US physician names John Gorrie built a refrigerator, based off of Oliver Evans design, with the sole

  2. Like Stacy, I tried my first bar today and indeed, it was delicious!! I had to research the reasoning behind the bars being in the refrigerated section of the grocery. While reading the background I found this confusing statement “The best bite into an apple is on that is crisp and fresh from the fridge.” I think your proofreader missed out here. This is no way reflects on the bar. Just thought you would most likely like to edit the wording for clarity. I loved the bar so much, I can’t wait to try the other flavors!! Thanks for making such a delish protein option.

  3. I can’t find the Gylcemic Index # for the Perfect Bar? I am on a Keto diet, so this is important. I love the taste of the Peanut Butter Bar

    1. Hi Michele – The GI range of our bars lies between a GI of 20 and 41. Since low GI is considered under 55, all of our bars have tested to be low glycemic index.

    1. Hi there, Peter – Unfortunately, we have discontinued our Fruit and Nut flavor in order to make room for some exciting flavor innovations coming down the pipeline. Stay tuned for innovations to come!

    1. Hey Paula! Feel free to check out the nutrition info for each flavor by going to!

  4. Even if the bar has not been refrigerated for over two weeks, is it still safe to eat?

    Btw, these bars are staple on our household. Everyone loves them especially our 1 y/o!

    1. Perfect Bars stay fresh out of refrigeration for up to one week. Since we don’t use chemical preservatives or overly-processed ingredients, refrigeration is required to maintain the optimal freshness, consistency and flavor of our bars. It also helps keep Perfect Bars in well, bar form! However, even after over a week out of refrigeration, our bars do not spoil, but they may lose their overall freshness and will start to dry out as the oils from the nut butters separate. So happy you’re a fan!

    1. Hey there! Feel free to check out the nutrition info for each flavor by going to!

  5. I tried my first bar chocolate hazelnut crisp.
    This bar is delicious
    Keeping in the refrigerator is great
    But I am looking for one I can take on the go.
    I definitely going to buy more so I can enjoy at home.
    Thank you for these bars

    1. Hey Linda! We’re so happy to hear you gave us a try! Please note, Perfect Bars are okay out of the fridge for up to a week – so you can take us on the go!

    1. Hey Cindy! Yes, Perfect Bars can be frozen – we suggest keeping them in a freezer safe bag to prevent freezer burn. Cheers!

  6. I love your bars but I am trying to get pregnant and need to know if you use Pasteurized products and honey? Thank you!

    1. Hey Tracy! Short answer is yes, Perfect Bar is safe for you to eat during pregnancy, though we encourage you speak with your physician to see if they’re right for you. We use organic wildflower honey that has been pasteurized and our organic nonfat dry milk and organic whole egg powder are pasteurized as well.

  7. Hi,
    I’ve been enjoying your bars for over a year and absolutely love them! I recently placed an order from It was heartwarming to read your family story. I live in New Jersey but I’ll be visiting family San Diego in October and was happy to see that your HQ is located there. As long as you keep making bars, I’ll keep eating them!

  8. LOVE perfect bars! This might be a silly question but just be sure… after removing a bar from the refrigerator for a full day can it be put back in the fridge and still be safe to eat?

    1. Yep! Our bars are good out of the fridge for up to one week – just put it back in the fridge to cool down, it’s still perfectly fresh!

  9. I love these ! I work a busy schedule in pediatric mental health. They are quick, easy and healthy . My question ? How long do they last refrigerated ? If I buy bulk should I freeze them ?
    Thank you !

    1. Hi Isabelle – We love to hear that Perfect Snacks help to fuel you through busy days! If you buy in bulk, you can freeze Perfect Bar to extent the shelf life. Otherwise, when stored in the fridge, Perfect Bar is freshest when enjoyed by the expiration date listed on each bar’s wrapper.

  10. Hi–how long do the bars remain fresh when kept in the fridge without losing their taste and texture? I tried freezing mine and felt the result was not good…

    1. Sorry to hear, Lisa! Perfect Snacks are best kept in the fridge until the expiration date printed on each wrapper. Although they can be stored in the freezer, too.

    1. Hi Marie – Absolutely! And, when you’re ready to enjoy them, you can stick the Perfect Bars back in the fridge or thaw one to eat straight from the freezer.

  11. This is a very good article. Thank you for sharing. I look forward to publishing more such works. There are not many such articles in this field.

  12. So disappointed that I can’t find the Fruit & Nut flavor anymore. It was our favorite, and the other newer flavors we’ve seen are just not appealing.

    1. Hi DC – Thanks for being a Perfect Snacks fan! It’s great to hear that you found one that you loved. Often times, products get discontinued in order to make room for the new. Our team is always crafting up tasty products and flavors. If you liked the Fruit and Nut Perfect Bar, you may also enjoy Blueberry Cashew:

  13. I love, love, love your Perfect Bars!! I always have 2-3 boxes of them in my fridge. I saw your response to a question about freezing Perfect Bars. I have 2 questions…1) does freezing them alter the nutritional benefits in any way?, and 2) after taking them out of the freezer, and placing them in the fridge for a couple of days before use, do they retain the same consistency and texture as when they’d only been refrigerated?

    1. Hi Alan – Thanks for reaching out! You can indeed freeze your Perfect Bars and it does not change the nutritional benefits. However, once you freeze them and unfreeze them, we do not recommend refreezing them. It does change the taste and texture. Hope that helps!

  14. My Son loves your Perfect Bars, I unfortunately can’t eat them because I’m allergic to peanuts and chocolate, I see there was a fruit and nut one mentioned which may have been ok but now I read your new one has cashews of which I avoid those now due to lectins that increase inflammation for me unfortunately. Another crazy thing is I guess we never knew they were refrigerated since we have gotten them in our pickup orders and did not know lol my son JUST said something about that on the PKG tonight, well we have bought them several times before too and just had them on the shelf with others in our pantry, usually he eats them fairly quick but these last one’s have been out for a couple weeks since our last pick up order. It’s crazy I don’t recall seeing that on the box before 😬 I hope to find one I can eat soon 😃

    1. Hi Vicki – Thanks for reaching out! Unfortunately, Fruit & Nut has been discontinued. So happy to hear that you finally found out that our products are refrigerated. Rest assured, that Perfect Bar is good out of the fridge for up to 7 days. Hope you can find a flavor that works with your dietary needs.

  15. So once my order is received
    They are only good in refrigerator for 7 days? I bought three boxes because I can’t find around here anymore . I can’t eat three boxes in 7 days. Help, do I freeze them????

    1. Hi Suzette – Our bars are good OUT of the fridge for 7 days, but are good IN the fridge by the “best by date” on the package, which should be a few months or more.
