Citrus fruits are a great natural pectin source for home canning, and many “no added pectin” recipes actually add natural citrus pectin in the form of lemon juice.
While citrus juice has a good bit of pectin, citrus seeds contain even more natural pectin that’s perfect for making homemade jam without store-bought pectin.
I love the idea of making homemade jams and jellies without having to buy storebought pectin. We sweeten our preserves with home-harvested honey or our own homemade maple syrup and learning to make my own natural pectin has been on my canning bucket list for a while now.
I’ve seen plenty of recipes for extracting pectin from apples, basically making super-concentrated apple jelly. That apple jelly is then added a few cups at a time to other low pectin fruit preserves.
It creates a good firm set, but it also adds a lot of apple flavor to the finished jam. Thus far, I’ve avoided it because I prefer the clean taste of storebought pectin since it doesn’t add any flavor whatsoever.
I generally make low sugar jams, so my preferred store-bought pectin is Pomona’s Universal Pectin which works wonderfully in low sugar and no sugar recipes. At some point, I looked up how it’s made and learned that it’s a natural citrus-based pectin. That got me thinking…can I make my own natural citrus pectin?
I started doing a bit of research into natural pectins, and learned that citrus fruits are loaded with pectin. Adding lemon juice to “no pectin added” jams actually adds a significant amount of pectin, and while it’s added mostly to increase acidity which makes the jam taste better…it’s actually helping it gel at the same time.
While citrus juice naturally helps jams gel, citrus seeds can be used as a natural pectin replacement. Several sources mention that you can actually see this in action by placing a few lemon seeds in a small amount of water overnight.
They say that it’ll be gel by the morning. I tried this, and no luck, it didn’t gel. What does work, however, is simmering the seeds in juice or water to create a pectin concentrate.
Since this test, I’ve made dozens of jellies and jams using citrus seeds as the pectin source. For jellies, simply simmer the seeds in the juice for about 30 minutes, then strain out the seeds and any fruit matter in a jelly bag. Then add sugar and finish the jelly. Thus far, I’ve used this method with success for moderate pectin fruits like chokecherries.

For low and no pectin fruits/vegetables, there’s also a good method I’d suggest. Start by simmering about 10-15 lemon seeds in about 2 cups of water for about 30 minutes (for every half pint of jam in the finished recipe).
The water will reduce to about 1/2 cup. At this point, it should visibly look like it’s gelling. Strain out the lemon seeds and add that mixture to the canning recipe in place of pectin.
I’ve done this for a zucchini jam, made with this pectin along with a small amount of lemon juice and a bit of lemon zest. Keep in mind you’ll need about 10-15 lemon seeds for every pint of finished jam, and adding the lemon juice and a bit of zest also really helps things gel.
Zucchini marmalade made with citrus seed pectin
For chunky jams instead of jellies, adding a sachet of citrus seeds in cheesecloth is an incredibly effective method.
Tie a tablespoon or two of citrus seeds in a bit of cheesecloth and add it directly into the jam pot. As the fruit simmers, the natural citrus pectin will be extracted from the seeds into the jam.
An even better option is to combine the two techniques and place all the jam ingredients together a few hours (or up to 24 hours) ahead of time. If you’re making strawberry jam, for example, add the sugar to the strawberries and then toss a sachet of citrus seeds into the bottom of the bowl.
The sugar will extract liquid from the strawberries, and then the citrus seeds will release pectin into this water. After that initial maceration period, place everything into the jam pot and start it simmering.
This is a great natural gelling agent for citrus jams obviously, and it’s what I used when making this kumquat jam.
Often though, jam making doesn’t directly involve a lot of citrus fruit. In that case, it’s best to save up citrus seeds in the freezer throughout the year. In the winter, we make a lot of limoncello (lemon liqueur) for summertime sipping, and I’m now saving the seeds from those lemons for use in my summer jams as well.
Anytime you use a lemon, orange or lime remember to save the seeds and you’ll have a good supply before you know it.

Great article! I’m going to use this. Thank you!
Nancy E. Sutton
Well done! I’ll be referring to this article a lot…. thanks for sharing all your research and experience.
Lucille Gasecki
Today I am using kumquat seeds to make pectin for addition to kumquat jam. Using the soaking method foe seeds. Thanks flow awesome ideas, especially about saving citrus seeds over time to use to make pectin.

Wonderful, I’m so happy to hear it!

Hi there from Northern BC Canada!
I am so excited to try making cherry (sour) jam using lemon seeds. BUT I just realised that in one place you say 10-15 seeds per finished pint, and in another , 10-15 seeds per finished half-pint. Could you please clarify? I’m doing this tomorrow – our own organic cherries are half-thawed – so I may have to just wing it but for next batch….. Thanks a bunch!
Administrator
How did your cherry jam work out?
Elaine
It’s hard to tell how big your seeds are. They look so different from mine (California organic lemons, avg 4oz) My seeds are very small. I imagine yours are from Florida, which may be irrelevant, but they look so plump and robust! A measure by weight rather than quantity would help, or how many it takes to cover a dime….March just went out like a LION. here….Stay well & eat lots of lemons!!
Erica
Thanks so much for this. I’ve also seen that guava has a lot of pectin. Do you think I could use guava seeds similarly? They are smaller, so I’d have to use a sachet, I guess.
Administrator
I think it would definitely be worth trying. Let us know how it works out for you.

I found this article when I was searching for a recipe for ‘home made pectin’. I, too, found many recipes for home made pectin with apples and how to can it.
However, I remembered a very old recipe I have for making marmalade. I formerly lived in Dundee, Scotland where marmalade was invented. A friend there shared an old family marmalade recipe that involved boiling the pips (seeds) in water until a gel forms. You then use this gel in your marmalade recipe to help it set. I was amazed at how well this natural pectin worked. The final product is a pleasantly firm jam. I was told that key to perfect marmalade is to use Seville oranges that are abundant in seeds and have a thick skin.
These oranges are hard to come by in most places and have a very short season (I live in Canada). I am going to try and get a few this winter and make marmalade, but also try and extract the pectin, can it and use it next summer. I have an idea that the citrus-based pectin may have a more complimentary flavour for some of my jams and jellies. I have found that the commercially available products like Certo give me a result that is too hard and do not add anything to the flavour profile.
Thanks for this.

Thank you for this article, I will definitely save my seeds. I’m a bit lazy and have been making my cherry and rhubarb jams this year with strips of peel tossed in, lemon for the rhubarb and lemon & orange for the cherry. Worked great. I put a strip per half pint jar for the rhubarb, a bit more for the cherry because I found the orange and tossed two extra strips of that in. Cooked with the fruit then took it out before putting the fruit in jars for water bath canning. Gelled up perfectly. Always looking for new ideas though and have seeds to save so will try that too.

Does using lemon seeds or citrus seeds for pectin, add bitterness to the jam or jelly?
If so about how much bitterness?
Why are you people not honest and upfront enough to give us the pros and cons of using citrus seeds for pectin?
And with what fruits are they best used.? And with which fruits are they not desirable?
I want to make rose petal jam.
And I want to know, if they would ruin the delicate flavor of rose petals?
If they would be suitable for rose petal jam, would it be a good idea to smash the seeds with a hammer to get more pectin out?
If citrus seeds would not be be good for making rose petal jam, would smashing the seeds for other fruit work, without ruining the flavor?
Administrator
The only place where you would have the potential for bitterness should be in the pith (or the white) of the fruit. The juice, seeds or zest should not contribute to any bitterness at all. I can assure you that there is no intent here to be anything but upfront and honest. Ashley works very hard to provide her readers with as much information as possible on practical self-reliance. This is a simple method that gives you an alternative to store-bought pectin. If you are interested in doing a rose petal jam using this method, then my suggestion would be to follow the directions in the post for low and no pectin fruits and vegetables. Ashley covers a wide variety of topics on the blog so it is impossible to try every possible combination. If you decide to try this method with the rose petals, we would love to hear about your experience so that we can all learn from one another. I have not personally tried smashing the seeds but if you’re curious you could always do a little experiment and use some seeds whole and do another batch with smashed seeds and see if you notice a difference.
Jodi
Can this be used for low/no sugar jams? And to what ratio should the pectin be used? I.e how much per kg of fruit?
Administrator
I would try this method for low and no pectin fruits. Start by simmering about 10-15 lemon seeds in about 2 cups of water for about 30 minutes (for every half pint of jam in the finished recipe). The water will reduce to about 1/2 cup. At this point, it should visibly look like it’s gelling. Strain out the lemon seeds and add that mixture to the canning recipe in place of pectin. Be sure to check back in and let us know how it works.

I find myself coming back time and again to your informative blog. I have been using lemons and their peels for pectin in my jams and jellies for some time, but this is the first time finding out about the seeds. Oh, when I think of all the seeds I have ‘wasted’!! Thanks for keeping it real for those of us who like the old ways best. Hugs!!!
Administrator
You’re very welcome. So glad you are enjoying the blog.
Maria R
WOW very good info!! I am going to try this. I have a question, would I be able to slowly collect seeds and either let them dry or freeze them to be able to have enough seeds on hand for when I need them? Thank you
Administrator
I think I would freeze them.
Linda weatherall
So you can use apple seeds too !
And crab apple seeds too for crabapple jelly? Oh my goodness that will save me so much work knowing that you can use the seeds too !!
Thank you for all the information and a big time saver !!
Administrator
You’re very welcome.
Christina
Do you have to do anything special to freeze the seeds or just put them in a jar or something? I’ve just started getting into canning/ making jellies and I love your blog!!
Administrator
The seeds should freeze just fine without any special preparation. You may want to flash freeze them on cookie sheets so that you don’t have one bug frozen mass of seeds.
poppasmurf669
do you have a list of seeds that have pectin. the only one you mention are lemons and apples and do other fruit have pectin say the squash family
Administrator
It’s mainly apples and citrus as far as I know. If you find other information please let us know.
Helen
Wow – I’ve been making jam/jelly for years and never knew this!! Thanks for the info! Will definitely try this!
Administrator
You’re very welcome. Let us know how it works if you decide to try it out.
Brenda
Hello, is it for every half pint or for every pint? Your recipe contradicts itself. Thank you, will try this , very new to jelly canning.
Administrator
The section where it talks about 10 to 15 seeds for a pint was specifically referring to the zucchini jam recipe where there was also lemon juice and lemon zest added which helps with the gel process. I would stick with 10 to 15 seeds per half pint if it’s a low-pectin fruit and you’re not adding in lemon juice or zest.
Barbara Goldstein
Can you estimate the volume of lemon seeds needed? I’ve have a few cups (of seeds) in my freezer just for this purpose. Do you know if adding more seeds to the same amount of water will will work?
Thank you!
Administrator
You will want about 10 to 15 seeds in 2 cups of water for every half pint of finished jam in the recipe.
Sandra Auvenshine
This blog is both a gift and a blessing! Last summer (2021), our area had heavy spring rains which made tons of very wet fruit which required more pectin than usual. I ended up purchasing food grade citric acid and adding 1/2 teaspoon to 4 cup batches of the cooked jams. It worked well, but the learning curve was wide due to adding, tasting, and possibly adding more citric acid in order to achieve jelling without making the jam bitter. This idea seems to be an excellent one, and I shall appreciate you each time I’m happily using it in my canning of jams!
Administrator
Thank you. We’re so glad you’re enjoying the blog.

You state: “many “no added pectin” recipes actually add natural citrus pectin in the form of lemon juice.”
Lemon juice has very little pectin, if it has any. It is used to lower the pH of the jelly, which helps any pectin that is present to gel.
The white pith or inner part of citrus peel has a lot of pectin.

Thank you so much for sharing this. I’m allergic to apples and oranges (lemons and limes are distantly related and don’t cause any allergic reactions for me) so I can’t eat regular pectin. I have tried my hand at homemade jams, but it’s been difficult to get them to gel enough which limits what jams I can make and requires me to use more sugar. I can’t wait to try this. Thanks again.
Administrator
You’re very welcome. We’re so glad it was helpful.

What a wonderful resource this is!! I just made my first batch of wild black raspberry jam using your 3 ingredient recipe and wow how good it is. The next batch I will use the lemon seeds in cheesecloth just to get it to gel up a little better but it’s really good as is now. My children and grandchildren think I’m amazing but I was sure to give you the credit. May God bless you and your family. I can’t wait to learn more and keep growing using the resources that grow in my garden and in my forests. Thank you again have a blessed day.

That’s so wonderful. I am so glad that you are enjoying the blog. You’re very welcome.

Great information! Have you ever used crabapple for pectin?
Administrator
I haven’t personally used them in that way but they were often traditionally used for their high pectin levels.
Edward
Thanks for sharing this idea. I had read about it before but did not give it much thought, now I am set to do it this way.
Kind regards from NZ
