LRF Welshy Posted March 6, 2022 Report Share Posted March 6, 2022 Hi all, I had a quick search and there weren't any recent posts about this. I'm looking to have a go at making some baits using gelatin and glycerine with some stinky fish oil. My first mix was 1:1 gelatin to glycerine with a small amount of water to bloom the gelatin. Is there anything I can add to slow down the dissolving of the gelatin? I'm getting 30-40 mins in the water before fine details start coming off but it's still structurally sound. I'm happy with this but longer would be nice. I'm making 2" worms for light rock fishing. Thanks Quote Link to comment Share on other sites More sharing options...
LRF Welshy Posted March 6, 2022 Author Report Share Posted March 6, 2022 This is my first attempt. A bit of flashing but pretty happy with the mold 1 Quote Link to comment Share on other sites More sharing options...
Go55 Posted March 14, 2022 Report Share Posted March 14, 2022 Looks good! Did you make a your own mold by yourself? Pourable silicone or urethane? Quote Link to comment Share on other sites More sharing options...

Or coat the baits with worm oil before using. Sorry, that's the best I've got for now. Quote Link to comment Share on other sites More sharing options...

I 3D printed it. I think pourable silicone would work as well though Quote Link to comment Share on other sites More sharing options...

I just saw others were using it. I found this recipe recently, https://github.com/seyDoggy/biopolymer-recipe/blob/main/recipes/gelatine/gelatine-v1_1.md A fair bit of research seems to have gone in to it so once my corn syrup arrives (can't get it as easily in the UK) I'll have go and see if it's better. 1 Quote Link to comment Share on other sites More sharing options...
wchilton Posted May 16, 2022 Report Share Posted May 16, 2022 The glycerin is acting as a plasticizer. Corn syrup (also many sugars) helps to retain moisture and can also act as a plasticizer to some extent. Thank you for the link to that recipe. I may give it a try sometime. Another recipe that may be useful to those following this thread is one I found for authentic gummy bears. The Sorbitol in the recipe helps make the pieces "springy". I don't think you need the sugar, but there's so much in the recipe that it could make a difference. I definitely think the citric acid can be eliminated (it's a flavoring in the small amounts used) and skip the candy flavor for something more appropriate in baits. Some citric acid may be useful as a preservative but I'd try excluding it first just to avoid possibility of something that acts as a deterrent. Here's a link to the recipe with Sorbitol. https://dolcefoglia.com/blogs/flavor-recipe-blogs/step-by-step-instructions-to-make-a-real-gummy-bear-recipe?ref=tfrecipes Quote Link to comment Share on other sites More sharing options...
Norwegian Posted May 16, 2022 Report Share Posted May 16, 2022 Great project! You might try to add transglutaminase, often called "meat glue". It is used in "molecular cooking" and is available online from many places like eBay. Probably Amazon too. It is used to glue various meats, fish etc together. It will also make it more resistent to heat. Regarding citric acid, it may work both as an attractant and a deterrent depending on the fish species. Anything under 0.5 percent is in my experience ok for most, but this is the species in Norway. Quote Link to comment Share on other sites More sharing options...

You had me at "meat glue" My corn syrup is arriving tomorrow and I'm currently printing a mold to make something similar to Marukyu mini isome so hopefully I'll have some baits to try on the weekend. I'll order some meat glue and give it a try. I'm not sure about the citric acid but I'll probably pick some up just in case. I can always make gummy bears or something Quote Link to comment Share on other sites More sharing options...

Since you are in UK there is lots of interesting options for taste/smell additives from the carp fishing bait industry. Quote Link to comment Share on other sites More sharing options...
