Gluten Removal From Fryers: Possibility Or Myth?

Gluten can be a serious issue for people with celiac disease or gluten intolerance, and even a crumb of gluten is enough to trigger an autoimmune response. As such, it is important to know if gluten can be removed from a fryer. The answer is that it depends on the type of fryer. Deep fryers, which use oil, are difficult to clean thoroughly, and gluten particles can remain in the oil and crevices of the fryer. Therefore, it is recommended to have a dedicated gluten-free fryer to prevent cross-contamination. On the other hand, air fryers can be cleaned easily and thoroughly between uses, so they can be used for both gluten-containing and gluten-free foods as long as proper cleaning procedures are followed.

Gluten particles can remain in the fryer

A study by Weisbrod et al. (2020) found that washing with detergent and water was enough to get rid of gluten, but this may not be possible with fryers that have lots of crevices. If the fryer has a wire basket, for example, it may be difficult to clean thoroughly. In this case, it is recommended to use a dedicated gluten-free fryer or get a separate basket for gluten-free cooking.

Another thing to keep in mind is the fan in the fryer. If the fryer has been used to cook foods with loose flour, there is a risk that flour could be circulating in the fryer the next time it is used. This could cause cross-contact, which is when gluten-free food is exposed to gluten, making it unsafe for people with coeliac disease to consume.

High heat will not eliminate gluten, so frying gluten-containing foods and then gluten-free foods in the same oil is not safe. Even if the oil is changed, gluten particles can remain in the fryer and contaminate the next batch of food.

Therefore, it is important to take precautions to prevent cross-contact if you are cooking for someone with coeliac disease or gluten intolerance. This may include using a dedicated gluten-free fryer, thoroughly cleaning the fryer between uses, or using separate baskets for gluten-free and gluten-containing foods.

High heat does not eliminate gluten

Gluten particles are difficult to completely remove from the crevices of a deep fryer. Even if the oil in a fryer has just been changed, the food cooked in it can still be contaminated. This is because minute particles of gluten can remain in the fryer, and these particles are enough to trigger an autoimmune response in those with coeliac disease.

For those who are gluten-sensitive or gluten-intolerant, eating food contaminated by gluten can cause intestinal distress ranging from discomfort and bowel problems to agonising pain. For those with coeliac disease, the problem is even more severe, with even the smallest exposure to gluten causing severe intestinal damage and an increased risk of cardiovascular disease and other serious medical conditions.

A dedicated gluten-free fryer can help to prevent cross-contamination. This means having a separate fryer that is only used for gluten-free foods, with strict rules for its use to avoid any cross-contamination. This can provide gluten-free diners with the confidence that their food has been prepared according to strict standards and procedures, protecting their health.

In addition to fryers, other kitchen equipment such as toasters, ovens, sponges, dishrags, condiments, and cutting boards can also be sources of cross-contamination and should be kept separate or thoroughly cleaned to prevent the transfer of gluten.

Gluten-free certification requirements

Gluten-free certification is a document that indicates a set of criteria regarding the manufacture of gluten-free products has been met. The certification process involves plant audits and laboratory data analysis. An internationally recognised certificate is then granted to the manufacturer as proof that the requirements for the production of gluten-free products have been satisfied.

There are several organisations that offer gluten-free certification, each with its own tests and standards for the levels of trace gluten they will allow. Here are some of the most prominent organisations:

• Gluten-Free Certification Organisation (GFCO): This group requires tested foods to contain less than 10 parts per million (ppm) of gluten, which is stricter than the Food and Drug Administration (FDA) requirement of under 20 ppm.
• Celiac Support Association (CSA): This group requires tested foods to contain less than 5 ppm of gluten and to be free from oats, even gluten-free oats.
• Allergen Control Group (ACG): This group requires tested foods to contain less than 20 ppm of gluten and is endorsed by Beyond Celiac as the Gluten-Free Certification Program (GFCP).
• Gluten-Free Food Service (GFFS): Certification by this well-respected organisation offers gluten-free diners the confidence of knowing that their food has been prepared according to strict standards and procedures designed to protect their health.

To obtain gluten-free certification, manufacturers must typically complete the following steps:

• Completion of an application form with a gluten-free certifying agency, providing details about all products and facilities considered for certification.
• Conducting a gap audit in preparation for an on-site audit.
• On-site plant inspection conducted by the certifying agency at the manufacturer’s expense.
• Correction of any issues and non-conformities identified during the audit.
• Meeting all requirements established and obtaining permission to use the certification logo or seal on packaging.
• Maintaining the integrity of the certification by scheduling annual facility audits and submitting gluten analysis results as agreed with the agency.

Cross-contamination risks

Cross-contamination is a serious issue for people with gluten intolerance or coeliac disease. Even a crumb of gluten can cause intestinal distress, severe intestinal damage, or even trigger an autoimmune response in those with coeliac disease. Therefore, it is important to be aware of the risks of cross-contamination and take steps to prevent it.

One of the main risks of cross-contamination is the use of the same oil for frying gluten-free and gluten-containing foods. Frying gluten-free foods in oil that has previously been used for gluten-containing foods can contaminate the gluten-free food. This is because gluten particles can be difficult to completely remove from the crevices of a deep fryer, and high heat does not kill gluten. Therefore, it is recommended to have a dedicated gluten-free fryer to prevent cross-contamination.

Another risk of cross-contamination is the use of the same utensils, such as spoons, tongs, and trays, for gluten-free and gluten-containing foods. It is important to always use separate utensils and trays when handling gluten-free and gluten-containing foods to avoid transferring gluten between them. This includes always using a clean baking tray and never placing gluten-free food directly on oven surfaces.

The oven itself can also be a source of cross-contamination, especially if it is a fan or convection oven. These types of ovens blow hot air around the oven space, which can cause gluten particles to be blown onto gluten-free food. It is recommended to cook gluten-free and gluten-containing foods separately and to cover gluten-free foods when cooking them in the oven. If cooking both types of foods at the same time, it is advised to place the gluten-free food on the higher rack to prevent crumbs or bits of gluten-containing food from falling onto it.

Other kitchen appliances, such as toasters, blenders, and mixers, can also be sources of cross-contamination. It is recommended to have separate appliances for gluten-free and gluten-containing foods, especially for toasters. If separate appliances are not an option, thorough cleaning between uses is crucial to remove any gluten particles.

In addition to appliances, cross-contamination can occur through shared condiments, such as butter, mayonnaise, and peanut butter. Gluten crumbs can be transferred from gluten-containing bread to the condiment and then to gluten-free food. It is important to have separate condiments for gluten-free and gluten-containing foods and to clearly label them to avoid confusion.

Overall, preventing cross-contamination requires vigilance and attention to detail. It is important to be aware of the risks and take the necessary steps to ensure the safety of those with gluten intolerance or coeliac disease.

Cleaning methods for gluten-contaminated fryers

Gluten is a protein found in grains like wheat, rye, and barley, and it can cause intestinal distress and severe intestinal damage to people with gluten intolerance or celiac disease. Even a minute amount of gluten can be harmful to those with gluten-related health issues, so it is important to prevent cross-contact and thoroughly clean fryers that have been contaminated with gluten.

• Use a dedicated gluten-free fryer: The most effective way to prevent gluten contamination is to have a separate fryer exclusively for gluten-free items. This eliminates the risk of cross-contact and ensures that gluten-free food is always prepared in a safe environment.
• Clean the fryer regularly: Frequent and thorough cleaning of the fryer is crucial. Disassemble the fryer and clean each component, including the basket, heating element, and oil reservoir. Use hot water, dish soap, and a clean sponge or brush to remove any food particles and grease. Ensure that all surfaces are scrubbed and rinsed well.
• Change the oil frequently: Oil can absorb gluten particles, so it is important to change the oil regularly, especially if gluten-containing foods have been fried. Use fresh, clean oil for gluten-free items to minimize the risk of contamination.
• Use gluten-free alternatives: When frying gluten-free foods, consider using gluten-free breading or batter. This helps reduce the risk of contaminating the oil with gluten particles.
• Cover gluten-free foods: If using a shared fryer, keep gluten-free foods tightly covered while frying. This helps prevent gluten particles from adhering to the food.
• Use separate utensils: Dedicate specific utensils, such as tongs or spatulas, for handling gluten-free items only. This minimizes the risk of transferring gluten particles from utensils to the gluten-free food.
• Clean surrounding surfaces: Gluten particles can spread to nearby surfaces, so it is important to clean the area around the fryer as well. Wipe down counters, tables, and other equipment with soap and water to eliminate any gluten residue.

It is important to note that high heat does not eliminate gluten. Therefore, proper cleaning and dedicated equipment are essential to ensuring the safety of gluten-intolerant individuals.
