The four zero-sugar or low-calorie soft drink labels read here all list the synthetic sweeteners E955 (sucralose) and E950 (acesulfame potassium). Coca-Cola Plus and 7UP low-calorie add E951 (aspartame). The article also gives the EFSA ADI where a source exists and each substance's status in Vietnam.
Summary
Coca-Cola Zero Sugar and Light list synthetic sweeteners (955, 950).
Coca-Cola Plus lists (951, 950, 955); 7UP low-calorie lists aspartame 951, sucralose 955 and acesulfame potassium 950.
All four labels list the preservative 211 and acidity regulators.
Appendix 1 of Circular 24/2019/TT-BYT lists 950, 951 and 955 with the function sweetener.
Zero-sugar soft drinks on the shelf
The Coca-Cola Việt Nam brand page describes Coca-Cola Zero Sugar as an additional choice “với dòng sản phẩm không đường, không calorie” (from the sugar-free, zero-calorie range) [1]. Suntory PepsiCo Việt Nam lists 7Up Lemon Soda (no sugar, zero calories) in its low-sugar product list [2].
On the label, “không đường” (sugar-free) shows as the line “đường 0 g” in the nutrition table per 100 ml [3]. The Zero Sugar ingredient list names no sugar but names synthetic sweeteners [4].
The article picks labels whose ingredients are printed in full on a readable page. Other zero-sugar drinks are not included.
Four labels side by side
The first three rows come from the Coca-Cola Việt Nam brand page. The 7UP low-calorie row comes from a product page on trungtamthuoc.com. The exact wording of each label is in the Sources section.
Sweeteners and other additives printed on the labels of four zero-sugar or low-calorie soft drinks
The three Coca-Cola labels print the same acidity-regulator group (338, 331(iii)) and preservative (211) [4][5][6]. The 7UP low-calorie label prints acidity regulators (330, 331)(ii) (296) and preservative (211), with no code 338 [7]. All four labels list natural flavouring.
The codes that appear on the labels
The three sweeteners are all named in Appendix 1 of Circular 24/2019/TT-BYT: 950 [8], 951 [8] and 955 [8]. The 950 and 955 rows give them the functions sweetener and flavour enhancer; the 951 row gives flavour enhancer and sweetener.
E950 acesulfame potassium: sweetener. Yenzo's E950 page gives no ADI because there is no verified source yet.
E955 sucralose: sweetener. in its 2026 re-evaluation EFSA concluded there is no need to revise the ADI of 15 mg/kg body weight a day [9].
E951 aspartame: sweetener. EFSA states an ADI of 40 mg/kg body weight a day [10].
E338 phosphoric acid, E331 sodium citrates, E330 citric acid and E296 malic acid: acidity regulators, printed on the label inside the brackets of “chất điều chỉnh độ acid”.
E211 sodium benzoate: preservative, on all four labels. E150d sulphite ammonia caramel (caramel IV): colour; the Coca-Cola label prints “màu tự nhiên (150d)”.
Each code chip links to that code's own page on Yenzo. That page gives its status in Vietnam with a cited source, and the ADI where a source exists.
How to read a zero-sugar soft drink label
Sweeteners sit in brackets after the phrase “chất tạo ngọt tổng hợp” (synthetic sweetener), for example “(955, 950)” [4].
The order of the codes is not fixed: Zero Sugar prints (955, 950), Plus prints (951, 950, 955) [4][6].
“Sugar-free” is read in the nutrition table: the line “đường 0 g” per 100 ml, and a separate carbohydrate line [3][6].
The 7UP low-calorie label prints a sub-code as “(330, 331)(ii)” [7].
Caramel colour is printed as “màu tự nhiên (150d)”, with the code number in brackets [4].
Caffeine and natural flavouring are printed by name with no code number; the Plus label also gives the caffeine content, 95.8 mg/l [6].
Scientific opinion on aspartame and sucralose
“The Panel concluded that aspartame was not of safety concern at the current aspartame exposure estimates or at the ADI of 40 mg/kg bw/day.”
For sucralose, EFSA's 2026 re-evaluation concluded there is no need to revise the current ADI of 15 mg/kg body weight a day [9]. The EU Scientific Committee on Food had set that value earlier; EFSA keeps it in this document.
The aspartame conclusion is tied to the exposure estimates at the time of EFSA's 2013 assessment and to the ADI in the quoted sentence [10]. Yenzo does not replace these figures with its own assessment.
For Coca-Cola Zero Sugar the label gives energy 0 kcal and sugar 0 g per 100 ml [3]. The ingredient list shows synthetic sweeteners (955, 950), a preservative (211) and caffeine [4]. The phrase “sugar-free, zero-calorie” is how the brand page describes the product range [1].
Are zero-sugar soft drinks harmful?
Yenzo gives no general verdict. The article gives the ADI where a source exists: aspartame 40 mg/kg body weight a day per EFSA 2013 [10], sucralose 15 mg/kg body weight a day per EFSA 2026 [9].
How do INS 950 and 955 differ?
950 is acesulfame potassium and 955 is sucralose. Appendix 1 of Circular 24/2019/TT-BYT lists both with the function sweetener [8][8]. On the Coca-Cola Zero Sugar label the two codes sit side by side in brackets: (955, 950) [4]. The Coca-Cola Plus label lists both together with 951 [6].
Are zero-sugar soft drinks good for you?
Yenzo does not rank products and gives no health advice. The article only shows which codes the label lists and their status under Circular 24/2019/TT-BYT. Two labels also list fibre: Coca-Cola Plus 11.3 g/l [6] and 7UP low-calorie 13 g/L [7].
