How to beat the LBG price spiral and still control ice cream quality and costs
The costs of Locust Bean Gum and Tara Gum – common ingredients for mouthfeel and stability in ice cream – are out of control. With Palsgaard’s latest LBG-free product, Palsgaard® ExtruIce 306, you can reduce your emulsifier/stabiliser costs by as much as two-thirds.
"We’re really confident in Palsgaard® ExtruIce 306 – both in terms of the cost reductions it can generate and the performance it offers."
— Claus Prior Hansen, Application Manager for Ice Cream and Dairy, Palsgaard A/S
The LBG and tara gum price crisis
Locust Bean Gum (LBG) has long been a go-to ingredient in ice cream, particularly in products with a luxury positioning. It acts as a stabiliser and thickener, preventing ice crystal growth, increasing creaminess and controlling meltdown. But LBG has never been associated with stability when it comes to cost. There have long been spikes in price and fluctuations in availability, but the situation has now spiralled out of control. With demand outstripping supply and speculators sitting on stocks, prices are more than eight times higher than two years ago.
Initially, tara gum represented a price-stable alternative. However, cost-in-use prices of that too have skyrocketed as a knock-on effect of the LBG situation.
”Fluctuating LBG costs are nothing new”, says Claus Prior Hansen, Application Manager for Ice Cream and Dairy at Palsgaard. “The problem now is that costs have gone sky high and stayed there – and tara has followed it. It’s not a feasible alternative anymore and it’s creating a lot of frustration for manufacturers.”
New LBG-free solution
Help is at hand in the form of a new addition to Palsgaard’s range of emulsifiers and stabilisers for ice cream. Palsgaard® ExtruIce 306 is free from LBG and tara gum, instead using a more price-stable option such as guar gum (E412) in combination with high-performing mono-diglycerides (E471).
The new blend is designed for applications including extruded and moulded ice creams, soft ice and plant-based frozen desserts. As a lean-label, palm-free and PHO-free option, Palsgaard® ExtruIce 306 is designed to deliver the same benefits as LBG as far as possible. These include a creamy, rich eating experience, high overrun and heat shock protection.
“Our goal was to create an alternative that offers manufacturers the functionality they’re used to, but at a reasonable price,” says Claus. “We’re really confident in Palsgaard® ExtruIce 306 – both in terms of the cost reductions it can generate and the performance it offers.”
The new addition to Palsgaard’s range is plant-based, and kosher and halal-certified, and it's produced in CO2-neutral facilities, helping meet the growing expectation of sustainability.
Furthermore, Palsgaard® ExtruIce 306 doesn’t require a major departure from what manufacturers are used to. “We do offer stabilisers based on different ingredients, like CMC and carrageenan,” Claus explains. “However, tradition is important in a lot of European markets. They’ve used LBG for a long time and they might not want to start using a very different ingredient like cellulose.”
Reduce costs by up to two-thirds
Claus’s calculations show that in recipes with LBG, emulsifiers/stabilisers can account for over 12% of the cost of the ice cream mix. “You can see the problem with that,” he says. “You have an ingredient that’s only contributing 0.5% of the recipe but 12% of the price.”
Using Palsgaard’s new solution, that figure can be taken below 5%. In terms of cost in use, the estimated reduction can range from half to two-thirds. “That’s obviously really attractive,” says Claus. “And it’s enough to allow the blend to be used at higher dosages to get even better levels of performance.”
No compromise on functionality
Furthermore, those savings don’t come at the cost of reduced functionality. “There is no single golden ingredient that can replace LBG,” Claus says. “However, Palsgaard® ExtruIce 306 comes close. In many areas, like melting resistance, the functionality is the same as you get with LBG. In others, it’s not an exact match, but it’s not far off.”
Palsgaard® ExtruIce 306 has also been found to offer great sensory properties, with an expert panel awarding it similar scores to LBG on body, creaminess, warmth of eating, cohesiveness of structure and chewiness.
Like Palsgaard’s other emulsifiers and stabilisers, Palsgaard® ExtruIce 306 is ready-mixed and integrated. The suspension of stabilisers in the melted emulsifiers, followed by an advanced spray-crystallisation process, creates a uniform, free-flowing powder. This means much easier handling – with no premixing with other dry ingredients required before addition to the mix.

Considering going LBG-free? Imagine the benefits
Claus encourages manufacturers to ask themselves a series of questions: “How has the cost of LBG affected your contribution margin? If you don’t address the issue, who’s going to pick up the cost? How much could a new solution reduce the cost of your product? And if your competitors solve the problem before you, what could happen to your market share?”
“The benefits aren’t necessarily the same for every customer,” he adds. “It might be the opportunity for a shorter ingredient list and a leaner label. It might be the security of supply you get from going LBG-free. It might simply be the value of finding a cost-effective new stabiliser without a drop in quality.”
Although the new products offer similar functionality to LBG, some recipe optimisation may be required. This is where Palsgaard’s global team of application specialists can help. Based in application centres across the world, they draw on the company’s 100 years of experience to offer a wealth of technical support to customers.
