In general, stabilizers serve several functions in food. They can enhance viscosity, which refers to the thickness or “thickness” of a substance. Stabilizers contribute to the smoothness and creaminess of products, preventing undesirable separation or settling. They also assist in emulsifying ingredients that would otherwise separate, such as oil and water. This ensures a homogeneous mixture and a pleasant eating experience.
In the case of ice cream, stabilizers contribute to the overall structure and texture of the frozen dessert. By preventing the formation of ice crystals, stabilizers help maintain a smooth and creamy mouthfeel, preventing a grainy or icy texture. They also enhance the resistance to melting, allowing the ice cream to retain its shape and consistency for a longer period.
One frequently utilized stabilizer in ice cream production is guar gum, a natural polysaccharide derived from the seeds of the guar plant. When incorporated into ice cream, it thickens the mixture, yielding a smooth and uniform texture. Through its binding action on water molecules, guar gum effectively hinders their separation and the subsequent formation of ice crystals. The outcome is a consistently creamy ice cream, even when stored for extended periods.
WHAT IS GUAR GUM?
Guar gum, also known as E412, is derived from the seeds of Cyamposis tetragonolobus, an annual crop cultivated in the Indian subcontinent. Its chemical structure bears resemblance to LBG (locust bean gum), featuring a main chain consisting of mannose units, with approximately half of these units having galactose side branches. Compared to LBG, guar gum possesses a higher molecular weight, and its galactose side groups are more uniformly distributed.
This molecular arrangement allows guar gum to readily dissolve in cold water due to its higher proportion of galactose units. The regions of the guar gum’s backbone that lack side chains are relatively smaller than those in LBG. Consequently, the hydrogen bonding between these regions is not sufficiently strong to form permanent cross-links, but it does lead to the formation of what are known as “hyper-entanglements.”

One of the advantages of guar gum is its versatility in accommodating various dietary restrictions. It is naturally gluten-free, making it suitable for individuals with gluten intolerance or celiac disease. Additionally, guar gum is vegan-friendly, as it is derived from plant sources. This means that even those following a plant-based or dairy-free diet can enjoy the creaminess of ice cream without compromising their dietary choices.
USES AND FUNCTIONS IN ICE CREAM MAKING
Guar gum offers a multitude of advantages, and one prominent benefit is its capacity to enhance the viscosity of ice cream mix. By functioning as a thickening agent, it fosters a silkier and more luscious texture that tantalizes the taste buds. Upon addition to the mix, guar gum effectively thwarts the formation of ice crystals. As a result, each spoonful of ice cream melts effortlessly in the mouth.
Guar gum also significantly contributes to the stability of ice cream. This makes the ice cream withstand fluctuations in temperature without compromising its quality. It also impedes the growth of ice crystals and safeguards the desirable attributes of the ice cream over an extended duration. This prolonged shelf life guarantees that your ice cream remains fresh and retains its deliciousness, even when stored for a considerable period.
The utilization of guar gum presents numerous advantages for both ice cream manufacturers and consumers. Manufacturers can benefit from guar gum as it offers a cost-effective solution to elevate the quality and consistency of their products. It enables them to create ice cream with an enhanced texture and increased stability. Hence, the likelihood of customer dissatisfaction and product wastage is minimized. Moreover, guar gum provides manufacturers with the freedom to explore a diverse array of flavors and ingredients, as it ensures consistent texture regardless of any additions made.
From a consumer perspective, guar gum guarantees a consistently delightful ice cream experience. Its thickening properties create a luxurious mouthfeel that coats your tongue and lingers on your palate. This enhanced texture enhances the overall enjoyment of the ice cream, making every spoonful a moment of pure indulgence. Guar gum also plays a crucial role in preventing the formation of ice crystals, ensuring that each bite remains as creamy and dreamy as the first.
MAKING HOMEMADE ICE CREAM WITH GUAR GUM
Guar gum can be found in most grocery stores, health food stores, and online retailers. When searching for it, direct your attention to the baking or natural foods section, as it is commonly stocked there in the form of standalone powder or as part of a stabilizer blend. Prioritize confirming that the product label explicitly indicates it is pure guar gum devoid of any additional additives. This critical step will guarantee of premium quality guar gum and enable you to achieve the desired outcomes in your ice cream creations.

It is essential to follow recommended proportions to achieve the desired results. Starting with a small amount and gradually increasing it allows you to find the perfect balance that suits your preferences. To give you a starting point, a 2015 study found that guar gum at 0.2% gives better texture in ice cream. Find the right balance between the ingredients. It is worth noting that the higher the concentration of guar gum incorporated, the stiffer the ice cream becomes. In most ice cream products, they contain 0.2 to 0.5% guar gum.
During adding of guar gum, blend it with a small quantity of sugar or other dry ingredients before introducing it to the ice cream base. This ensures that it is evenly distributed and prevents the formation of clumps. Feel free to make experiments by exploring diverse ingredients and flavors,
