Non-Food Uses of Carob Gum
Carob gum is a natural galactomannan obtained from the endosperm of carob seeds and is known as a thickener and stabilizer in food with the code E410. However, the usage area of this range is not limited to the kitchen. Thanks to its water-binding, viscosity-forming and film-making properties, the carob gum; It is used in many sectors such as paper, textile printing, cosmetics, pharmaceuticals, adhesives and coatings.
In this article, we discuss the non-food uses of the carob scale, which feature is used in these areas, its historical uses ranging from photographic film to parachutes, and the points to be considered in industrial supply based on sources.
What is Carob Gum? A Quick Reminder
The carob seed consists of three main parts: the outer shell, the endosperm and the embryo. The carob gum is obtained by separating and grinding the endosperm from these parts. This product, called "locust bean gum" (LBG) or "carob bean gum" in English, is chemically a galactomannan; that is, it is a polysaccharide in which galactose units are attached at sparse intervals to a long main chain of mannose sugars.
In the food industry, carob gum is an approved additive used with the code E410. The European Food Safety Authority (EFSA) re-evaluated the use of carob gum as a food additive in 2023. For detailed information on the structure of the bean and the process leading to the production of the gum What is Carob Seed? You can take a look at our article.
In this article, we leave aside the uses of the gamut in food and focus on its world outside of food. In the statement of the Ministry of Agriculture and Forestry in 2020, the areas where carob is used in industry are listed as follows: food, cosmetics, paint, textile, medicine, paper, plastic, petroleum, furniture, matches and pharmaceuticals. This extensive list shows how versatile carob is, and especially products obtained from the kernel.
Features That Make the Range Valuable Outside of Food
The ability to use carob gum in different sectors is based on several basic physical properties:
- Thickening Enhancement: Significantly increases the viscosity of water even when used in small amounts.
- Water binding: Retains water and delays the drying or decomposition of the system.
- Film forming: It can form a thin layer when dry.
- Stabilization: Reduces the settling of solid particles in mixtures and the separation of phases.
- Synergy: When used in combination with some other hydrocolloids, it can create stronger structures.
- Natural origin: It is a renewable raw material of vegetable origin.
As well as these properties work to regulate the texture of ice cream in food, they work just as well for the smooth spread of dye on fabric in textile printing or for the stability of a cosmetic cream. It is only the purpose of the application that changes.
Sector Sector Non-Food Uses
Below, we discuss the main sectors where carob gum is used other than food and which feature of the gum is used in these sectors.
Paper Industry
One of the oldest and most well-known uses of carob gum outside of food is paper production. A comprehensive review by Martins-Loução et al., published in the journal Plants in 2024, lists papermaking among the top non-food uses of carob gum. The introductory text of the Val Rahmeh Botanical Garden in France and historical sources describing the carob industry in Cyprus also state that the gum was used in the paper industry.
In paper production, vegetable gamuts are generally used as auxiliary substances added to the pulp. Such additives can help distribute the fibers more evenly in the pulp and improve some of the physical properties of the paper. Which gamut will be used and in what proportion is determined by the type of paper and the process conditions of the manufacturer.
Textile Printing and Dyeing
The textile industry is one of the important users of the carob gum outside of food. Martins-Loução et al. specifically state that the scale is used in textile printing. In textile printing, the dye is applied directly to the fabric in a thickened printing paste, not in liquid form. The consistency of this paste directly affects the sharpness of the pattern and the even distribution of the dye on the fabric. Thickeners such as carob gamut create a carrier medium that controls the flow and dispersion of the dye.
Its relationship with dyeing also dates back to ancient times. The Hampshire Mills Group publication describing the carob industry in Cyprus and the history published by Anassa state that the scale obtained from the kernel was used in dyeing. According to the same publication, the tannin obtained from the bark and leaves of the carob tree was also used especially for dyeing sails. In an article in Wildside Holidays, it is stated that the scale is used in textile and dye products.
Cosmetics and Personal Care
The carob gum can also be included in cosmetic formulations as a thickener and stabilizer. The compilation by Martins-Loução et al. counts creams, lotions and hair care products among the cosmetic products in which the range is used.
The function of the gum in cosmetics is similar to that in food: adjusting the consistency of the product, supporting the stability of the emulsion and providing a pleasant texture during application. The increasing demand for ingredients of natural origin increases the importance of herbal gums in the cosmetics industry. In Turkey, the potential of carob in this field is also on the agenda; In the statements made at the harvest festival held in Alanya in 2025, it was stated that the Carob Workshop evaluated the potential of the product in many areas from agriculture to trade, from food to cosmetics. The point to be emphasized here is that the gum is primarily a technical auxiliary in cosmetics; claims about the effects of the products on the skin require a separate evaluation.
Pharmaceuticals & Pharmaceuticals
In the statement of the Ministry of Agriculture and Forestry, medicine and pharmacy are also counted among the industrial uses of carob. The tourism text introducing the old carob mill in Limassol also states that processed carob is used to make medicines.
In pharmacy, herbal gums can generally be considered as binders, thickeners or carrier excipients in formulations such as tablets, suspensions and gels. Pharmaceutical uses of carob gum are also investigated within this framework. These uses are related to the technical function of the product; it does not mean that it cures any disease.
Petroleum and Drilling Applications
In the ministry's statement, petroleum is also among the industrial uses of carob. Gases in the galactomannan group attract attention in applications such as drilling fluids due to their water-thickening properties. Drilling fluids; It undertakes functions such as cooling the drill bit, carrying the crumbs formed during drilling to the surface and supporting the well wall, and they must be of appropriate viscosity for these functions.
However, it should be noted that guar gum is the most widely used galactomannan in the oil and gas sector. The use of carob gum in this field is not as common as guar; the main market of the gum is the food industry. We discuss the differences between carob gum and guar gum in a separate article.
Adhesives, Coatings, and Other Applications
The compilation by Martins-Loução et al. states that carob gum is also used in adhesives and coatings. The film-forming and bonding properties of natural polymers enable them to be evaluated in such applications.
Historical sources about the carob industry in Cyprus also confirm this diversity. It is reported that some of the products processed in the carob mill in Limassol are converted into pellets used in glue making. In the ministry's statement, matches and furniture making are also counted among the industrial areas associated with carob.
Historical Uses: From Photographic Film to Parachute
Non-food uses of carob gum are not new. In the first half of the 20th century, a significant part of the carob seeds exported from Cyprus were used in industry. Sources give interesting examples of the uses of this period:
- Photographic film: The Hampshire Mills Group publication and the history of Anassa cite the use of gamut in photographic film; in the Limassol tourism promotion, photographic film plates are mentioned.
- Parachute: According to the Hampshire Mills Group publication, the gum was also used in the production of parachutes during World War II.
- Dyeing and paper: The same sources also count dyeing and papermaking among historical uses.
Some of these historical uses have lost their importance today with the development of synthetic materials. However, these examples help to understand why carob seeds have long been considered a strategic raw material.

Quality and Supply in Non-Food Use
There may be differences in quality expectations between the carob gum produced for non-food applications and the food-grade carob gum. For food use, compliance with the purity criteria defined for E410 and food legislation is mandatory. In industrial use, technical parameters such as viscosity, particle size, solubility behavior and color come to the fore.
In any case, the quality of the gamut starts with the raw material. Clean, correctly graded and free of impurities helps to obtain a more efficient and consistent product during the husking and grinding stages. Therefore, the selection of a bean supplier for gamut manufacturers is a critical step in terms of the quality of the end product.
