Effect of xanthan gum on agar agar gels?
I just recently got into using agar agar to prepare solidified gels, and I'm wondering what effect adding xanthan gum to the mixture before gelling it would have. I'm particularly interested in trying to use the xanthan gum to replace fats in recipes like egg yolks.
Does anyone happen to know what difference one would note between a gel set with only agar(roughly 1 tsp powder per cup liquid) and a gel set with agar(same ratio) and the addition of xanthan gum before it gels (and how varying the amount of xanthan gum would provide different results)? If so I would greatly appreciate the information.
And if anyone happens to know the same information but for adding glucomannan instead of xanthan gum to an agar gel that would be helpful.

In lower concentrations of Agar Agar you'll have weeping (Syneresis); Xanthan gum is generally used to lower syneresis when combined with other hydrocolloids. Apart from slight texture changes; you'll benefit from less weeping.
per this paper Evaluation of Blends of Alternative Gelling Agents with Agar and Development of Xanthagar, A Gelling Mix, Suitable for Plant Tissue Culture Media; Agar Agar + Xanthan gum (i.e. Xanthagar) is considered as an economically viable alternative for using Agar Agar directly. As XG cheaper compared to Agar.

Can you use xanthan gum with agar agar?
Agar agar is an algae-based thickener that acts much like a vegan form of gelatin. It requires a little more prep than most replacements, but you can swap it with xanthan gum in a 1:1 ratio.Is agar agar and xanthan gum the same?
Xanthan gum is another popular substitute for agar agar powder. Unlike starch-based agar substitutes, xanthan gum is basically made from bacterial fermented sugar. Xanthan gum will not harden your recipe in the same way that agar will, but it will thicken it and keep it from seperating.Can xanthan gum form gel?
Xanthans. Xanthans, known commercially as xanthan gums, form high-viscosity, pseudoplastic solutions that are unaffected by changes in temperature, pH, or salt concentration. Xanthan is a non-gelling hydrocolloid, but it does form gels when combined with agarose, kappa-type carrageenans, konjac glucomannan, or LBG.How do I make my agar jelly firmer?
Unlike gelatin, you can melt the gelled mixture (if you wanted to add another ingredient, pour it into a different mold, add more agar agar to make the gel firmer or add more liquid to soften it), bring it to a boil again, then cool it again without compromising its gelling abilities.LET'S TEST IT | How to make CLEAR GEL | GELLING AGENTS \u0026 THICKENERS | EP.1
