歐盟專家組對卡拉牙樹膠的安全性進(jìn)行評估發(fā)現(xiàn)，卡拉牙樹膠的基因毒性不會對人體構(gòu)成影響，動物實(shí)驗(yàn)1250 mg/kg 體重每天的劑量下未產(chǎn)生毒性。人體按照100 mg/kg 體重每天的劑量服用的耐受性較好，因此專家組得出結(jié)論認(rèn)為，沒有必要制定確切的卡拉牙樹膠ADI值，然而成人每天的攝入量不能超過7000mg。

    Following a request from the European Commission, the EFSA Panel on Food Additives and Nutrient sources added to Food （ANS） was asked to deliver a scientific opinion on the re-evaluation of karaya gum （E 416） as a food additive. Karaya gum （E 416） is an authorised food additive in the EU. Karaya gum （E 416） as specified in the Commission Regulation （EU） No 231/2012 is derived from the exudates from the stems and branches of strains of Sterculia urens Roxburgh and other species of Sterculia （family Sterculiaceae） or from Cochlospermum gossypium A.P. De Candolle or other species of Cochlospermum（family Bixaceae）。 The Panel concluded that there is no safety concern at the refined exposure assessment for the use of karaya gum as a food additive and that there is no need for a numerical ADI for karaya gum. The Panel further concluded that exposure to karaya gum by the use of this food additive should not exceed 7,000 mg/person per day in adults, the level at which some experienced abdominal discomfort.
