What is quinoline yellow, and where is it used?
Quinoline yellow, also known as E104, is a synthetic yellow food colouring agent commonly used in the food industry . It belongs to the class of azo dyes and provides a yellow shade between pale yellow to yellow-brown to various food and beverage products. Quinoline yellow is utilised in a range of food applications, including confectionery, desserts, beverages, sauces, and processed foods . Its intense yellow hue makes it a popular choice for enhancing the visual appeal of products.
Purported Health Benefits
While quinoline yellow is primarily used as a food colouring agent, there are no specific health benefits associated with its consumption [2, 3]. It is important to note that quinoline yellow is a synthetic additive and does not possess inherent nutritional or health-promoting properties.
Recommendations for Safe Consumption
While quinoline yellow is generally considered safe for consumption within established limits, there have been concerns about its potential health implications.
Individual Sensitivities: Be aware of any sensitivities or allergies you may have to synthetic food colourings. Some individuals may experience allergic reactions, such as respiratory issues, skin rashes, or digestive discomfort, after consuming quinoline yellow. If you experience any adverse reactions, it is advisable to avoid its consumption and seek medical advice if needed [4, 5].
Read Product Labels: Be vigilant and read food product labels to identify the presence of quinoline yellow or other synthetic food colourings. This allows you to make informed choices based on your preferences or any sensitivities you may have.
Consult Healthcare Professionals: If you have specific health concerns, such as known allergies or sensitivities, or dietary restrictions, consult with a healthcare professional or registered dietitian who can provide personalised advice tailored to your individual needs and help you navigate potential risks associated with quinoline yellow.
Moderation: Consume foods containing quinoline yellow in moderation. While it is considered safe within regulatory limits, excessive intake may lead to potential adverse effects [6, 7]. Follow recommended serving sizes and consider overall dietary balance.
Varied Diet: Focus on consuming a diverse range of whole, unprocessed foods that are naturally colourful and rich in nutrients. This reduces reliance on synthetic food colorings and ensures a well-rounded nutritional intake while minimising potential risks associated with additives.
Food Choices: Opt for foods that naturally possess vibrant colours without the need for synthetic additives. This includes incorporating a variety of fruits, vegetables, and herbs into your diet, which not only provide natural colours but also offer numerous health benefits.
Differential concerns regarding its potential toxicity have resulted in its acceptance for use in European countries, but banishment in Japan and USA .
