What Is E132 Indigotine ?

E132 Indigotine, also known as Indigo Carmine, is a synthetic dye utilized predominantly to color an array of consumables. From candies to baked goods, this blue dye has been a go-to choice for manufacturers aiming to enhance the aesthetic appeal of their products.

It is an organic salt derived from indigo by aromatic sulfonation, which renders the compound soluble in water. It is approved for use as a food colorant in the U.S. and E.U. to produce a blue color and has the E number E132.

Indigotine is also used as a dye in the manufacturing of capsules and it is produced synthetically and does not come from any animal or plant sources.

Chemical Structure

The molecular charm of E132 lies in its chemical structure: C16H8N2Na2O8S2. It’s a disodium salt of indigo with a distinct blue hue, bearing a molecular weight of 466.36 g/mol. Understanding the chemical structure is pivotal as it sheds light on its interaction with other substances and its behavior under various conditions.

What Is E132 Made From?

E132 Indigotine’s journey from a mere concept to a colorful reality is intriguing. It’s synthesized from indigo dye, which historically was extracted from plants. Although it’s noted that indigotine is naturally found in certain plants, the commercial version of this colorant is synthesized, thus classifying it as a synthetic color

Possible Side Effects

While it is generally considered safe for consumption by regulatory authorities like the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), there are still some potential side effects and concerns associated with its usage:

  1. Allergic Reactions: Some individuals may be hypersensitive or allergic to E132. Allergic reactions to food additives like E132 can manifest as hives, itching, redness, swelling, or even more severe symptoms such as difficulty breathing or anaphylaxis.
  2. Gastrointestinal Distress: E132 can potentially cause gastrointestinal discomfort in some individuals. This might include symptoms such as stomach cramps, diarrhea, or nausea. These effects can be more pronounced in people with pre-existing digestive issues, sensitive stomachs, or irritable bowel syndrome (IBS).
  3. Hyperactivity in Children: There is some debate regarding the potential link between artificial food colors, including E132, and hyperactivity in children, particularly those with attention-deficit/hyperactivity disorder (ADHD). While the evidence is not conclusive, some studies have suggested that certain food dyes may exacerbate behavioral issues in susceptible children. As a result, some countries have imposed restrictions on the use of E132 and other synthetic colorants in products targeted at children.
  4. Unknown Long-Term Effects: Long-term consumption of synthetic food additives like E132 can be a concern due to the lack of extensive, long-term studies. It’s challenging to predict the potential health impacts of sustained exposure to such additives over an extended period.

To minimize the potential risks associated with E132 and other synthetic food additives, you can consider the following precautions:

  • Read food labels carefully, especially if you have known allergies or sensitivities.
  • Be aware of potential links between synthetic food dyes and hyperactivity in children, and limit their consumption in such cases.
  • Consume a balanced diet with a focus on natural, unprocessed foods, as they are less likely to contain synthetic additives.

Dosage and Administration

The European Union (EU) has approved E132 as a food additive and has established an acceptable daily intake (ADI) of 5 mg/kg body weight This means that an average adult weighing 70 kg can safely consume up to 350 mg of E132 per day.

However, this amount may vary depending on the individualโ€™s sensitivity, health condition, and dietary habits. For example, people who are allergic to this colorant should avoid it completely, while pregnant and breastfeeding women should limit their intake to avoid potential risks to the fetus or infant.

Is E132 Halal or Haram?

E132 is considered halal due to its synthetic origin, as it does not originate from animals. However, it is crucial to ensure that the solution or mixture used in its formulation does not contain any haram (forbidden) ingredients, thus maintaining the halal status of the E132 dye.

Regarding the issue of the E123 additive, it follows a similar principle, where it is deemed halal unless there is a specific prohibition. Factors that could render it haram include:

  • Sourcing from prohibited items, such as alcoholic beverages or animals not slaughtered according to Sharia guidelines.
  • Containing substances harmful to the human body.
  • Unlawful acquisition, such as through theft or methods contrary to Sharia’s standards.

Final Words

In conclusion, E132 Indigotine, or Indigo Carmine, is a synthetic blue dye commonly used to enhance the visual appeal of various food products, such as candies and baked goods. It holds a halal status due to its synthetic origin, provided that the ingredients used in its production adhere to halal guidelines.

While generally considered safe, some individuals may experience allergic reactions or gastrointestinal discomfort, and there’s ongoing debate about its potential connection to hyperactivity in children. As with any food additive, it’s essential to consume it in moderation and be mindful of individual sensitivities.
