About
Green raisins (kishmish) are shade-dried or artificially dehydrated grapes (Vitis vinifera L.) that retain their greenish-golden colour through sulphur dioxide fumigation to prevent oxidative browning. They are widely consumed as a snack, confectionery ingredient, and traditional remedy, and are a significant agricultural export from Afghanistan, Iran, and Central Asia.
Safety summary
Green raisins are nutritionally dense, providing dietary fibre, potassium, iron, and polyphenols, and are generally recognised as safe for the general adult population. The primary safety concern is the residual sulphur dioxide (SO₂) used in processing, which can reach up to 564 ppm in raisins; the WHO/JECFA Acceptable Daily Intake (ADI) for sulphites expressed as SO₂ is 0.7 mg/kg body weight/day. Individuals with asthma or sulphite sensitivity may experience adverse reactions, and high natural sugar content warrants moderation in those managing blood glucose.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | Dried grapes/raisins are permitted to contain sulphur dioxide (E220) as a preservative under Regulation (EC) No 1333/2008 on food additives. Sulphites must be declared on labelling when present above 10 mg/kg as SO₂. The ADI for sulphites is 0.7 mg/kg bw/day (JECFA/WHO).source |
| Food Standards Agency (FSA) / Food Standards Scotland (FSS) (United Kingdom) | Approved | Sulphur dioxide and sulphites in raisins and dried fruits must be declared as allergens on food labels in the UK under retained EU allergen labelling legislation. Individuals with asthma are flagged as higher-risk for sulphite reactions.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Green raisins/kishmish are permitted dried fruits under FSSAI Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011. Sulphur dioxide is permitted as a preservative in dried fruits with a maximum residue limit of 500–2000 mg/kg depending on product specification. Mycotoxin (aflatoxin) monitoring is mandated by FSSAI for imported and domestic raisins.source |
| Taiwan FDA (TFDA) (Taiwan) | Approved | Golden raisins are explicitly listed among 17 food items in which sulphites as bleaching agents are permitted under Taiwanese food safety regulations; all other food items are required to be free of sulphite residues. |
