Drying Fruits (2003)
- dfxm12 3y agoRaisins are just grape jerky :) Arrange pretreated fruits on drying trays in single layers, pit cavity up. Dry at 140 degrees F (60°C) in an oven or dehydrator. Does anyone have an oven that can maintain such low temps?
- mithr 3y agoThe Anova Precision Oven is one, it goes as low as 77F (25C).
- checkyoursudo 3y agoMuch lower than that and you are getting into dual use oven/refrigerator mode!
- thfuran 3y agoAt least in the US it seems to be the exclusive purview of high-end ovens, but there are ovens with proofing modes, which would be even lower temperature than that. Warming modes of around 150F are somewhat more common.
- dylan604 3y agoi've seen recommendations about setting the oven at the lowest temp possible, and then leaving the door slightly open. i've also seen electric only ovens be able to set lower temps than gas only. i've only ever dried herbs in the oven because of the temp issue. for everything else, i just bought a dehydrator that can be set to the lower temps.
- 0_____0 3y agoI've used the incandescent light in my oven to keep sourdough starter warm before. If the wattage is too low, you could hack together a simple thermostat driven relay and a larger light bulb run into your oven.
- ch4s3 3y agoA big cup of hot water works pretty well too.
- phone8675309 3y agoI bet my car hits 140 in the summer sun.
- jrgoff 3y agoI accidentally made raisins one summer by forgetting a cluster of grapes on my car dash for a few days. They tasted pretty good!

- bagels 3y agoToaster ovens are cheap and have good enough thermostats.
- a012 3y agoNot household ovens as far as I know, this is why I bought a commercial one (UNOX - an Italian brand) that allows me to set a low temperature. It’s basically a convection oven with PID.
- rrauenza 3y agoI use convection mode on my oven and set it to 170F. Convection mode on my oven doesn't actually use the temperature you set it to, but some auto slightly lower temperature to accommodate for the convection. I don't think it's as low as 140F, but I get good sundried cherry tomatoes out of it.
- hedora 3y agoFor dehydrating food, you'd also want it to have a fan + turn over air pretty rapidly. That speeds up the process, which matters even more if it's monopolizing your oven! A "food dehydrator" mode would be much more than at least half of the dozen modes our oven does have; I wonder why they omitted it, or if one mode could be tricked into that use case. It definitely has a fan to actively vent hot air from the oven cavity (I think this is mostly to protect its computer, and not particularly useful for anything except cost reduction), and it has a proof mode, so I know the thermostat can drop down far enough. As an aside, LG ovens have the worst firmware I've ever encountered on a home appliance, and it is by a large margin.
- hammock 3y agoJust put your oven on convection roast at the lowest temp possible... boom dehydrator mode
- danuker 3y agoFirmware on an oven? My cheap dehydrator has a thermostat and a on/off switch. My cheap oven also has a timer. How is software warranted on an oven?
- amenhotep 3y agoOvens are one of the few appliances where I can see some sense in smartifying them, honestly. Turn it on to preheat before getting home (or if you're just too lazy to get up), have it send alerts to your phone when the timer goes off so you don't miss it due to being on the other side of the house or having your headphones on, check how long's left on the timer before deciding whether to start watching a new episode, stuff like that. There's a combination of long cycle time + necessity to respond urgently that creates an actual use case that isn't there for eg toasters or dishwashers.
- dylan604 3y ago>Turn it on to preheat before getting home I know so many people that shove used pots/pans in the oven when they just can't face doing the washing. Turning the oven on when you're not home just sounds like a recipe for disaster.
- purpleflame1257 3y agoMany air fryers have a "Dehydrate" setting.
- fullspectrumdev 3y agoThe “multi cooker” unit I have made by Ninja has such a feature, though I’ve found various aftermarket “racks” are needed for good performance dehydrating various stuff. It’s fucking excellent for drying mushrooms, for example. Whenever I have some left over from cooking or harvest that I can’t use immediately, I just dry and powder them to use as seasoning in soups and stocks and such. Other food scraps from cooking that are not destined for compost can be treated similarly, if one wants to get into making their own spices.
- kwhitefoot 3y agoMy oven can be used to prove bread dough at 30°C
- shalmanese 3y ago> Does anyone have an oven that can maintain such low temps? They seem quite common for ovens outside of the US but most digital US ovens I've used have a minimum temp of 170F for what I assume is some liability reason.
- Fnoord 3y agoI own an Excalibur food dehydrator (since approx 2005), but using it requires adequate space and electricity. We have a fig tree, a pear tree, and tons of herbs. Most of that is for whatever frolics outside though. Last year I was also on vacation at a farmer who had tons of fruit and nut trees on his yard. But people didn't wanna come to pluck so it ended up rotting on the floor. That made me sad, and it makes me sad I have this amazing device unused. But at least the birds and other animals such as bees and insects get to utilize them.
- nsenifty 3y agoBosch ones (at least the one I have) can even be set to 100F. I haven't actually tested how well it maintains such low temps, but I use it for proofing.
- anon____ 3y agoYou can just prop the door slightly open, and use convection, if possible. It sounds energy inefficient, but when you are drying, not just heating, you also have to replace that humid air in the oven.
- rdtsc 3y agoMy grandpa used his attic to make raisins. I don't know the process he used but we kids would sneak up on a rickety wooden ladder and there they were, hanging from a strings. The raises were never like the packaged ones, they were a lot bigger and chewier and a lot tastier.
- shpat 3y agoHere’s the fact sheet they reference[0] with nutrient loss info. Interestingly, vitamin C seems to suffer the most. [0] https://nchfp.uga.edu/how/dry/csu_dry_vegetables.pdf https://nchfp.uga.edu/how/dry/csu_dry_vegetables.pdf
- dylan604 3y agoVitamin C is a temperamental thing. It oxidizes very easily, and then just becomes this inert thing. Luckily, it turns color when it oxidizes, so it lets you know it happened. Skin care products try to stabilize it with other ingredients while packaging it in UV protective containers. Some even go so far as to recommend keeping the product refrigerated. There are now many options for adding Vitamin C with the majority of them reducing the effectiveness of the Vitamin C to gain stability in the product as in some are not as efficiently absorbed by the body, but won't oxidize. Some are water soluble, some are oil soluble. Of all of the ingredients, VitC is definitely the most finky
- hammock 3y ago> Vitamin C is a temperamental thing. It oxidizes very easily, and then just becomes this inert thing. Doing exactly what it was designed to do, biologically speaking.
- tomcar288 3y agoas far as vitamin and mineral intakes, vitamin C is the thing you need to worry about the least because it's so highly abundant in so many fruits and vegetables. I've calculated VitC density in foods and normalized it to calorie intake: It's incredibly abundant in many real foods.

- jkonline 3y agoWe've been looking for additional uses for our new air fryer, including drying fruit. This is super helpful and interesting. Thank you!
- h2odragon 3y agoThe cooler you can keep things while drying them, the more flavor the final result has. Airflow is important; but only up to a (rather small) velocity: as long as air is circulating around everything and not static you're good; beyond that you're just going to be adding heat and dust. Air will soak up an astounding quantity of water, but it takes time. I cold dry flowers at room temp in a closed cabinet (no outside air ventilation, full internal re-circulation) for 4 to 7 days, usually. Depends on density and temp. If I need to rush I'll use a rock salt dehydrator bucket in the cabinet.
- 11235813213455 3y agoWater in fruit is extra pure, so it's a bit sad to "waste" it, but if there's no other choice it's good
- jamiek88 3y agoWhat gives you that idea?! Heavy metals and pathogens being retained in fruit juices is widespread and heavily checked by USDA etc.

(slightly different topic: hydration) Of course the idea is to eat organic fruit, not some commercial ones heavily treated and not very nutritive too
- schwartzworld 3y agoHow can it be pure if it's in fruit? I'd think the fiber, sugars, acid, etc would all be considered impurities.
- fuzztester 3y agoI've had a specific kind of dry dates in India in childhood. They taste pretty good. Unlike the "wetter" ones (which are not really wet, but with more water content), you can keep them in your mouth for a while, thereby getting the taste for a longer time. They are lighter brown in colour than the fresh ones. Images: https://www.google.com/search?q=dry+dates+india https://www.google.com/search?q=dry+dates+india
- goda90 3y agoWe bought a countertop dehydrator to handle the excess tomatoes I grew one year since I didn't want to try pressure canning sauces. I think our favorite uses are for apples, strawberries and bananas. We've had some good experiences with cucumber that resulted in tangy chips that were great to dip, but I think that was dependent on my garden producing weird, oversized cucumbers.
- dylan604 3y agoI grow a lot of catnip. A few weeks ago, I dried enough to fill up an empty 40oz peanut butter jar. My cats won't touch the store bought stuff anymore. The stuff I dried is so fragrant that the cats magically show up like the "runs can opener" meme. Makes me want to become a catnip dealer at my local farmer's market. I've tried bananas, but honestly, the whole slicing part and keeping them whole slices is just too much effort for me. Do you have a tip on how to keep it from being so frustrating?
- goda90 3y agoWe do the bananas when they are just starting to go brown, so they still have some integrity. Some stores sell them at a discount when they reach that state so it can be a good chance to make more. I imagine fully brown would be messy. When we get some to that point they usually go into the freezer to be kept for banana bread instead.
- jerrysievert 3y agodrying celery is one of my favorite things to dry, dry it, grind it, and use it for things like soups, or dressings, or even popcorn. it adds a good flavor to a lot of things.
