Locust Bean Gum vs Tapioca Syrup: which is worse?

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.

What is Tapioca Syrup?

Tapioca syrup is produced by enzymatically or acid-hydrolyzing tapioca starch (derived from cassava root). It is often marketed as a 'clean label' alternative to corn syrup, particularly in organic and natural food products. Chemically, it is similar to corn syrup, consisting primarily of glucose polymers.

Documented risks

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.

Tapioca Syrup: Tapioca syrup contributes added sugar to the diet and has a high glycemic index comparable to corn syrup. A 2019 investigation by the Clean Label Project found that many 'organic' snack bars sweetened with tapioca syrup had sugar contents equivalent to candy, despite their 'natural' branding. The FDA has noted that tapioca syrup, when listed on ingredient labels without quantification, may obscure the total sugar content of a product. Health impacts are equivalent to those of other refined sugars.
