About

What it is and where it shows up.

A sweetener blend is a generic food-industry term for any combination of two or more approved sweetening agents (e.g., aspartame + acesulfame-K, sucralose + stevia, erythritol + monk fruit, or sugar + stevia) used to sweeten foods and beverages while mimicking the taste profile of sucrose. Blends are formulated to achieve synergistic sweetness, mask off-notes of individual sweeteners, reduce caloric content, or meet specific regulatory use-level limits for each component.

Safety summary

The regulatory and scientific consensus.

No single safety profile or ADI applies to 'sweetener blend' as a category; safety depends entirely on the identity and concentrations of the constituent sweeteners, each of which is individually regulated and has its own ADI. Most approved component sweeteners are considered safe at authorised use levels for the general adult population; however, aspartame — a common blend component — was classified by IARC as a Group 2B possible carcinogen (2023) based on limited evidence, while JECFA simultaneously reaffirmed its ADI of 40 mg/kg body weight. Individuals with phenylketonuria (PKU) must avoid aspartame-containing blends due to the phenylalanine content.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	No single E-number or authorisation covers 'sweetener blend' as a category. Each permitted sweetener (identified by its own E-number) must appear on the food label by name or E-number. EFSA is conducting an ongoing re-evaluation of all sweeteners authorised before 20 January 2009. Blends are permitted provided each component is individually authorised under Regulation (EC) No 1333/2008 and used within its own maximum use levels and ADI.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	FSSAI has established individual safety limits for non-caloric sweeteners (stevia, acesulfame-K, aspartame, sodium/calcium saccharin, sucralose, sorbitol) based on JECFA ADIs and Codex harmonisation. Specific blends such as erythritol–monk fruit combinations have been individually approved under FSS (Novel & Special Foods) Regulations 2017. FSSAI has not recommended non-sugar sweetener blends for weight loss or blood glucose control.source
FDA (Food and Drug Administration) (United States)	Approved	No single approval exists for 'sweetener blend' as a composite ingredient. Each constituent sweetener must individually be either FDA-approved as a food additive or qualify as GRAS. Six high-intensity sweeteners are FDA-approved: saccharin, aspartame, acesulfame-K, sucralose, neotame, and advantame. Steviol glycosides and monk fruit extract have GRAS status. Blends of approved/GRAS sweeteners are permissible provided each component is used within its approved conditions.source

Who should approach with care

Whose guidance would steer them away.

Phenylketonuria — Aspartame, a prevalent blend component, metabolises to phenylalanine; individuals with PKU cannot metabolise phenylalanine and must avoid all aspartame-containing sweetener blends — mandatory label warning required in the US, EU, and India.

Diabetes — FSSAI has explicitly stated that non-sugar sweetener blends are not recommended as a means of controlling blood glucose in individuals with diabetes, and individual responses to sweetener components may vary metabolically.

Children — EFSA's re-evaluation programme and WHO guidance highlight that ADIs for individual sweetener components are set for adults, and children's lower body weight means they may approach or exceed ADIs at typical intake levels, particularly with high consumption of sweetened beverages and foods.

Pregnancy — Regulatory bodies have not established specific safety data for sweetener blends during pregnancy; as the safety of several individual components (e.g., saccharin, cyclamate where permitted) during pregnancy is not fully established, cautious use is advised.
