I bought a one pound tub of chicken liver from the grocery. Thawed them out and put the entire contents in a blender, liver and all the blood in the tub. It blended into a thick soup. I added two heaping tablespoons of Sodium Benzoate for preservative. That has been sitting in a quart canning jar for about two weeks and it has become like pudding.

I want to add an anti freeze to it. I have both glycerine and polypropylene glycol that I can use for that. The quart jar is a little over half full, I'd say about 18 oz. volume of material. My understanding is that you put about 25% by volume of anti freeze in the jar. Is that correct? Is one kind of anti freeze better or worse than the other?

Which ever I add will make the mixture thinner so I also have some blood meal I can add in to thicken it up. I want to end up with a paste like material, not a pour-able liquid.

From reading on this forum I see that I might need to worry about mold forming on the liver. I have a jar of Methylparaben coming and would like to add some to the mixture to control mold. So far I have not found any information about the quantity of Methylparaben to add to bait mixtures for mold control. Can anyone give me a little guidance with that?

Would adding some kind of lure material to the mix make it more attractive to fox, bobcat or coyote. I have beaver castor, beaver sack oil, and a few other things. I mainly want to rely on the liver content as a bait and use other attractants on the set so I can vary the smells on a given set. But if something added would be a scent carrier I'd like to try it, perhaps in a smaller portion of the bait, till I find something that works well for me.

Any and all suggestions welcome.

You could try Dobbins' bait solution.

The best use of MP is to prevent mold. I use SB and MP together very often as do most bait and lure makers. I avoid glycol all together. Have had it get a sour smell after its been out in the air a few days. Glycol is a type of alcohol and i prefer ethanol. Around here i just buy everclear.
Ethanol is for tincturing and glycerin is anti freeze. I like to put caster in a blender with a little glycerin to make a paste also

Joe, I paid $21, it included postage, for a half pound of methylparaben from Amazon.

Danny, What you say about the mold control use of methylparaben is what I have understood. How much should be added to a pint of meat product for that purpose?

Remember the more glycerin you use the more the odor is diluted. I was pleasantly surprised how cold it could get here at night without my lures and baits freezing. Setting lures out on your colder nights works better for me to judge if or how much glycerin to use compared to sticking them in my freezer, but thats just my way.I'm not most experienced but I have actually got to where I prefer diethyl phthalate for tincuring.

Dp for animal tincturing and ethanol for plants

I mp at 1/4 cup per gallon of finished scent

You can have the most experienced individual on this forum tell you what and how to do or use something, if it doesn't give you the responses you desire from the animal you're after it won't matter how you mix up bait.
Jmo- dp, everclear, vodka, glycol etc....all preference.

Only thing that matters is when you test that ingredient, you get the responses you want. How you get there is preference through your own opinion through trial and error during testing on the animal you're after. Believe it or not bait doesn't need 20 of the best known ingredients or tinctures with an in-house chemically formulated blend of secrecy to be effective. I would keep the bait making simple. You start filling up notebooks with "what's the next best thing" and adding this and that. It's only going to make adjusting a bait that much harder when trying to determine what needs to be adjusted for ratios or what was added that had a negative impact on the response from animals.

Interest is what you are looking for.

Joe I don’t know. I bought some mp one time that was horrible on line. I now buy from joshs frogs. I tried mp only with the junk stuff in horse meat and it didn’t stop the taint. Good stuff could stop taint i just went back to sb for preservation and mp for mold.

I was initially wondering that, too, Joe.
AJE

The Boss told me 1/3 cup / gal

because SB does not inhibit mold...........

Don't know who does ?.........you know Paul Dobbins don't you?

I do use methylparaben and sodium benzoate in the same bait. Bait preserved with sodium benzoate will tend to grow mold. The small amount of the methylparaben is strictly a mold retardant. I learned this remedy for mold in bait from Carroll Black. Also, I've found that methylparaben is not nearly as good a meat preservative as sodium benzoate.

^^^^^^^False

SB does have mold inhibiting properties, just not as good as mp and other specific preservatives to inhibit mold growth.

When it comes to liver less is more! before you start adding read up on t-mad. IMHO i've never had a batch of liver mold! ive got a bucket of 8 year old liver and its still the same year to year.Nothing added just straight course ground livers

temperature fluctuations and condensation are what cause mold prevent that mold isn't a issue

Not in my experience with the bait I make. It is very likely to develop mold if only sodium benzoate is used for the preservative. You probably have more experience making bait and using those two preservatives than I do, so I'll defer to your superior knowledge on this subject.

Much appreciated..How does the saying go? "in my experience..what works for me...IMHO etc"? Well I've placed small personal batches in buckets out in the shed and in a damp basement and haven't run into any issues with mold from season to season. If I was looking for shelf life or selling, then a more specific mold inhibitor would be added for safety measures. You are the master lure maker not I. I use what works for me and I know sb would do just fine without developing mold especially in small batches for personal use from season to season. If I'm not mistaken I believe ya buddy who is a well known lure maker has typed the same thing regarding sb holding little value regarding inhibiting mold n the past. Any backlash on his comment? I don't recall anyone commenting on it..???

Save the popcorn Joe, no show with the boss. He's like the CIA, when they've seen enough you just disappear.
