Invert Sugar vs Locust Bean Gum: which is worse?

What is Invert Sugar?

Invert sugar is a mixture of equal parts glucose and fructose produced by the acid or enzymatic hydrolysis of sucrose. It is sweeter than table sugar by about 25% and has enhanced moisture-retaining properties. Bees naturally produce invert sugar in honey through the enzyme invertase.

What is Locust Bean Gum?

Locust bean gum (LBG) is a galactomannan polysaccharide extracted from the seeds of the carob tree (Ceratonia siliqua), native to the Mediterranean. It is a fine white to yellow powder that forms a thick gel when dissolved in hot water. It synergizes strongly with xanthan gum and carrageenan to enhance gel strength.

Documented risks

Invert Sugar: Invert sugar poses the same metabolic risks as other added sugars. The free fructose component is metabolized directly in the liver, and excessive fructose consumption has been linked to non-alcoholic fatty liver disease, increased triglycerides, and insulin resistance, as documented in multiple reviews including a 2013 paper in Current Opinion in Lipidology. At moderate consumption, it is not specifically more harmful than sucrose. Regulatory agencies worldwide permit its use without restriction.

Locust Bean Gum: Generally recognized as safe. EFSA's Panel on Food Additives confirmed the safety of LBG in 2017, noting no concerns at current dietary exposures. It functions as a soluble dietary fiber and can have mild prebiotic effects. No significant adverse effects have been documented in human or animal studies at food-relevant doses.
