Why is carrageenan in almond milk? The truth about this controversial additive

5 min read

According to a 2021 review, carrageenan is a polysaccharide extracted from red seaweed used as a food additive in various products, including almond milk. Its primary role is to create a creamy texture, prevent separation, and extend the product's shelf life, functions that are especially important for a water-based product like almond milk. However, the use of carrageenan in almond milk and other foods has sparked controversy and health concerns among consumers.

Quick Summary

This article explores why carrageenan is used in almond milk, detailing its function as a stabilizer, emulsifier, and thickener. It covers the history, production, and differing scientific perspectives regarding its safety, empowering consumers to make informed dietary choices.

Key Points

  • Texture and Stability: Carrageenan thickens and stabilizes almond milk, preventing the natural separation of almond solids and water for a consistently creamy texture.

  • Extended Shelf Life: It helps ensure that almond milk remains uniform and fresh for a longer period, aiding in the even distribution of added nutrients.

  • Controversial Health Concerns: Concerns exist due to research, primarily animal studies, linking it to inflammation, gut issues, and glucose intolerance.

  • Regulatory vs. Advocacy Views: While bodies like the FDA classify food-grade carrageenan as safe, organizations like the Cornucopia Institute advocate for its removal, citing health risks.

  • Read the Label: To avoid it, consumers must check the ingredient list, as many brands now offer carrageenan-free alternatives.

Why Manufacturers Use Carrageenan in Almond Milk

Carrageenan's inclusion in almond milk is a matter of food science designed to achieve specific product qualities. A raw mixture of ground almonds and water, the basis for almond milk, is inherently unstable. Without a stabilizing agent, the solid almond particles and the liquid water would naturally separate over time, resulting in an unappealing, watery product. This separation, known as sedimentation, would require consumers to shake the carton vigorously before every use.

Manufacturers use carrageenan to solve this problem by taking advantage of its unique properties as a hydrocolloid. A hydrocolloid is a substance that forms a gel-like consistency when mixed with water. In almond milk, a tiny amount of carrageenan creates a suspension that keeps the almond particles evenly distributed throughout the liquid. This ensures a consistent, smooth texture and a satisfying mouthfeel that closely mimics traditional dairy milk, meeting consumer expectations for quality and convenience. The additive also enhances the product's shelf stability, extending its freshness and preventing spoilage by ensuring a uniform distribution of fortified vitamins and minerals.

The Controversies and Health Concerns Surrounding Carrageenan

Despite its technical benefits, carrageenan has been a subject of significant debate and consumer concern for decades. The controversy stems from a body of research, particularly animal studies, that has raised questions about its potential health effects. A key point of contention is the distinction between two forms of carrageenan: undegraded (food-grade) and degraded. Degraded carrageenan, or poligeenan, is a known inflammatory agent and potential carcinogen used primarily in laboratory settings to induce inflammation in test subjects for research purposes. Critics argue that even food-grade carrageenan, when exposed to the acidic environment of the stomach, can break down into the more harmful degraded form, potentially causing gut inflammation.

Potential Health Issues Linked to Carrageenan

  • Intestinal Inflammation: Studies have shown that carrageenan can cause a cellular inflammatory response in test subjects, potentially leading to gastrointestinal issues, ulcerations, and polyps in sensitive individuals.
  • Increased Intestinal Permeability: Sometimes referred to as 'leaky gut,' carrageenan may increase the permeability of the intestinal lining, allowing larger particles to enter the bloodstream, which can trigger immune responses and systemic inflammation.
  • Glucose Intolerance: Research in animals has indicated that carrageenan may negatively impact insulin sensitivity and decrease glucose tolerance, suggesting a potential link to diabetes.

Scientific Body Opinions on Carrageenan Safety

Regulatory agencies and scientific bodies have different perspectives and conclusions on the safety of food-grade carrageenan. The debate is complex, involving interpretations of animal studies, testing conditions, and the potential for degraded forms to appear in food. Below is a comparison of different perspectives.

Comparison of Views on Carrageenan Safety

Entity Position on Carrageenan Basis for Position Notable Action/Finding
US Food and Drug Administration (FDA) Approved as safe (Generally Recognized as Safe - GRAS). Considers that the low levels of undegraded carrageenan in food are safe for consumption. Maintained its stance despite some public pressure.
World Health Organization (WHO) Expert Committee Deems food-grade carrageenan safe for infant formula (2014). Reviews animal studies and sets acceptable daily intake levels. Reaffirmed safety for infants after reviewing new studies.
European Food Safety Authority (EFSA) Permitted as a food additive (E-407) but with restrictions on use in infant formula. Based on toxicological reviews and safety data. Acknowledges concerns and takes a more cautious approach for infants.
The Cornucopia Institute Calls for the complete removal of carrageenan from the food supply. Cites numerous animal studies linking carrageenan to health problems like inflammation and GI distress. Publishes research and advocates for consumers to avoid carrageenan.

How to Find Carrageenan-Free Almond Milk

For those who wish to avoid carrageenan, several options exist, and many brands now offer specific carrageenan-free products. The key is to be a diligent label reader. The ingredient list on a product's packaging will specify whether carrageenan is included. Many brands highlight its absence on the front label with phrases like 'No Carrageenan' or 'Carrageenan-Free'.

Alternatives to Carrageenan

  • Gellan Gum: This is a popular alternative used by many almond milk manufacturers. Gellan gum is also a polysaccharide derived from bacterial fermentation and provides similar stabilizing properties to carrageenan.
  • Xanthan Gum: Another common food additive, xanthan gum is also a polysaccharide used as a thickening and stabilizing agent in many foods.
  • Lecithin: Derived from sources like sunflower or soy, lecithin can function as an emulsifier to prevent separation.

Alternatively, making your own almond milk at home is a surefire way to control every single ingredient. A simple recipe involves soaking almonds, blending them with water, and straining the mixture. This ensures a fresh, additive-free product, although it will require shaking before use. For those seeking an easy-to-find commercial option, a quick check of the ingredients list is the most reliable method.

Conclusion

In summary, the presence of carrageenan in almond milk is a technical choice made by manufacturers to enhance the product's texture, stability, and shelf life. It helps prevent the natural separation of almond solids and water, providing a consistently creamy and appealing beverage. However, its use remains a source of debate due to persistent concerns about its potential inflammatory effects, primarily extrapolated from animal studies involving a different, degraded form of the substance. While regulatory bodies like the FDA consider food-grade carrageenan safe, some consumer advocacy groups and individuals report adverse digestive reactions and recommend avoiding it. As a consumer, understanding why carrageenan is used allows you to weigh the evidence and decide whether to seek out the many available carrageenan-free options. The choice ultimately depends on your personal health perspective and dietary preferences.
