revolutionizing fast food frying operations

Revolutionizing Fast Food Frying Operations

News Frying Oil

In the highly competitive QSR-Industry, maintaining high-quality food standards while optimizing operational efficiency is crucial. A multinational fast food concept recently re-evaluated its frying operations to improve efficiency, food quality, and establish better methods for maintaining frying oil quality. A key part of this initiative involved evaluating different oil filtration technologies. The results revealed significant advantages of using the SuperSorb® CarbonPad over traditional methods.

Recently our FILTROX Team conducted a field test with a major QSR operator. Read here about the challenges we faced, the objectives, and finally about the resulting operatinal benefits and time savings.

 

The Challenge

The fast food chain aimed to enhance its frying operations by:

  • Extending the service life of frying oil
  • Improving food quality
  • Avoiding filter media replacement because of blinding

To achieve these goals, the company compared its current filtration product, a filter paper with an activated silica-based loose filter powderagainst the SuperSorb® Carbon Pad.

The Protocol and Objectives

The study was designed to determine which filtration medium best slows down frying oil degradation, thus extending its service life and improving product quality. The test protocol included:

  • Cleaning each fryer using the company’s new boil-out procedure
  • Evaluating fryers individually without oil rotation
  • Daily oil sampling and testing Total Polar Materials (TPM)
  • Monitoring sensory properties of food products
  • Assessing filtering time, operating costs, and employee acceptance of each filtration method

Success Criteria

The success of each filtration method was measured by:

  • Extended useful fry-oil life over current methods
  • Reduced frying oil usage
  • Filtering time efficiency
  • Actual cost reduction
 

RESULTS

Over a four-week period, the study revealed that the SuperSorb® CarbonPad significantly outperformed the other filtration methods. Key findings include:

Extended Oil Life

  • SuperSorb® Carbon Pad: Average of 7 days
  • Filter Paper + Activated Silica-Based Powder: Average of 4 days

Faster Filtering Time

SuperSorb® required only 15 minutes for all three fryers, 30 minutes less than the other filter pad with powder.

Safety and Handling

SuperSorb® uses no powder, eliminating handling and safety issues.

Effective Filtration

SuperSorb® with its embedded adsorbents, such as activated carbon, removes other chemical frying oil contaminants, filters down to 0.5 microns, compared to 10 microns for other filter pads.

Enhanced Product Quality

Improved food quality was consistently observed with SuperSorb®-filtered oil.

Cost Efficiency

SuperSorb® had a lower daily cost, compared to the filter paper with powder. Since the filter paper and powder combination blinded during they day, they had to replace paper and powder more than once a day. Only one SuperSorb® Carbon Pad was needed for the same amount of frying, saving fiter media costs and reduced labor costs.

Employee and Operational Benefits

One of the most significant advantages noted was the ease and speed of using the SuperSorb® Carbon Pad. Employees found the filtration and frying oil filter pad placement faster and easier, increasing the likelihood of proper and consistent use. This user-friendliness is crucial in a fast-paced restaurant environment, where efficient operations are essential.

Conclusion

The SuperSorb® CarbonPad has proven to be a superior filtration technology for fast food frying operations. Its ability to extend oil life, improve food quality, reduce costs, and simplify the filtration process makes it an invaluable tool for fast food restaurants aiming to enhance their frying operations. By adopting SuperSorb®, QSR operators can achieve better operational efficiency and deliver higher quality products to their customers.

keep your deep fryer clean

Keep your Fryers Clean

News Frying Oil

Cleaning deep fryers is essential for operators, that rely on their fryer. The best way to clean your fryer is by boiling it out.

What Does It Mean to Boil Out a Deep Fryer?

 Boiling out a deep fryer is the process of removing old, degraded oil, adding water and cleaning solution, and then boiling the water to thoroughly clean the interior of the fryer and remove any oil and frying debris.

Why Should I Boil Out My Deep Fryer?

One of the main reasons operators should boil out their deep fryer is because it protects the taste of their food. Old food and dirt in your deep fryer can affect the oil, which affects the flavor of the food fried.

Boiling out your deep fryer also helps frying oil to last longer. If operators don’t boil out your fryer, there may be proteins, polar contaminants, and other materials that can affect frying oil immediately after it’s added, which causes oil to deteriorate faster. By boiling out the deep fryer, you ensure frying oil to last longer and save money on replacement costs.

If operators get into the habit of regularly boiling out their deep fryer, they will be able to use fewer chemicals, because it will prevent dirt from building up.

Step-by-Step Instructions

for boiling out a deep fryer

filter_1

Drain all the oil from the fryer and safely, discard it via an oil caddy and an approved oil discharge container. 

filter_2

Use a fryer cleaning rod to clean remaining debris out of the drain line if needed. 

filter_3

Rinse the fryer with hot water to remove excess undrained fat.

filter_4

Fill the fryer with cool water within at least 8-10 cm (3-4″) of the top. Then, add your deep fat fryer cleaner. Check the instructions on the bottle to find the specific amount you need to use. If you clean a pressure fryer, please DO NOT CLOSE THE LID!

filter_5

Boil slowly as per cleaning-aid instructions.

filter_6

Allow the fryer to drain slowly. When the water has drained, use a suitable fryer brush to clean the sides, top, and heating elements of the fryer.

filter_7

Rinse thoroughly to remove all residue (any soaps left into the vat will quicker degrade the new oil).

filter_8

Add new oil.

Note: refer to the operations manual of the fryer for safety and fryer specific information! Always wear PPE (personal protective equipment)!

Boiling out deep fryer at regular intervals can help improve the taste quality of fried food, cut down on oil replacement costs, and improve the life of your fryer. It’s a simple process that involves removing the oil, adding water, and cleaning solution, boiling until stuck-on grease and dirt come off, and finally adding in fresh oil.

frying oil filtration

Frying oil cascading versus cradle to grave

News Frying Oil, Uncategorized

Extending the frying oil shelf life whilst maintaining product food safety and quality is one of the goals of food service operators. Filtering the frying oil regularly is by far the most important recommendation to achieve it.

Besides filtering, there are 2 other procedures restaurants follow to try to extend oil life, named frying oil cascading (rotation) or “cradle to grave”.

Frying Oil Cascading

is the procedure where the frying oil is transferred from one vat to another, until it is deemed unfit for use as per food service operator quality standard procedure or legislation.

cascading frying oul process

“Cradle to Grave”

is the method of keeping the frying oil in the same vat that point is reached. 

frying oil management

The oil degrades at different rates in the fryers vats when frying different types of food. When operators use cascading, oil is moved from a Vat with lower debris, lighter oil color (less “hostile” frying oil environment) to Vats with higher debris and darker oil color (more aggressive circumstances).

From experience, the frying oil life is maintained better when the “cradle to grave” operation is followed. There are some technical explanations that could support the preference for the “cradle to grave” approach.

Below are the advantages of it:

  • No risk of frying oil contaminants being transferred from one frying vat to another.
  • Less risk of allergens and off flavors cross contamination among products.
  • No work involved in transferring the fryer oil from one vat to another.
  • Easier to control frying oil service shelf life via frying oil quality parameters.

By working with the cradle to grave practice, the frying oil is allowed to run its normal degradation course and be discarded when the end point frying oil quality parameter is reached, thus maintaining a longer fry-life.

Therefore, it is always a good practice to maintain cradle to grave approach in restaurant fryer operations to obtain longer oil fry-life and avoid product food safety and quality issues.

frying oil quality legislation

Frying Oil Quality Legislation

News Frying Oil, Uncategorized

The quality of fried food is highly linked to the conditions of frying oil. Although there is not one specific worldwide regulation for frying oil quality, several countries have adopted guidelines or created regulations for the matter. Most of them are based on studies done regarding frying oil stability during cooking and possible deleterious effects in human health.

Nowadays, Total Polar Compounds (TPC) or Total Polar Materials (TPM) is the most common frying oil parameter. These are the most reliable to determine the oil quality, according to the German Society for Fats Science (DGF). The TPM value provides information on the quantitative proportion of polar and non-polar compounds in cooking oil. In Europe, determining the TPM value has become the standard reference protocol.  For assessing the fats and oils quality in deep-frying conditions in foodservice, it is one of the best quality indicators. As a result, several countries have set the limits of 24 to 27% TPM for degraded frying oil. In countries such as the USA and Australia, where TPM is not a legal limit value, the parameter is becoming increasingly used by foodservice operators as an internal benchmark.

Some countries use acid value (AV) or free fatty acids (FFA) as quality standard. According to American Oil Chemists’ Society Official Methods and Recommended Practices, FFA is obtained dividing AV by the factor 1.99.

Below are some countries with guidelines or regulations in place to determine frying oil quality for Foodservice.

frying oil degradation

Frying Oil Degradation Process

News Frying Oil, Uncategorized

Frying oil degradation is a very complex process. It involves several chemical and physical reactions between the frying medium and the product. During frying, physical changes occur, such as heat being transferred from the heating elements to the frying oil and consequently from the oil to the food. Heat causes water in the food to evaporate and reacts with the frying medium.

In addition, there are several chemical reactions occurring among food, frying medium and air. These interactions, influenced by the frying oil, food types as well as frying conditions and oxygen availability are interrelated and produce a complex mixture of substances. The chemical reactions frying oil undergoes are oxidation, hydrolysis and polymerization.

frying oil degradation

Oxidation

The oxidation is the interactions of the frying oil with oxygen, either coming from air or from the product. Oxidation by-products are hydroperoxides, ketones, dimers, among others. These compounds evolve to other volatile and non-volatile components, like alcohols and aldehydes.

frying oil degradation

Hydrolysis

Hydrolysis is the chemical reaction between water and the frying oil, producing, among other components, free fatty acids. Free fatty acids can increase the hydrolysis process by interactions with steam released by the product during the frying process.

frying oil degradation

Polymerization

Polymerization results in the formation of very large molecules (high molecular weight) in the frying oil. Polymers increase frying oil viscosity and cause foaming. In extreme cases it forms a yellow lacquer on the frying heating elements and vat wall. It impairs a bitter taste and higher frying oil absorption in the fried product.

.

Oxidation, hydrolysis and polymerization by-products are considered polar substances, which can be measured as total polar materials or components (TPM or TPC). TPM/TPC is the best parameter to evaluate frying oil quality in Foodservice.

different types of frying oil filtration

Frying Oil Filtration Methods

News Frying Oil, Uncategorized

Frying is a popular method of cooking because it is quick, easy and usually results in delicious food.

During the frying process cooking oil is being exposed to heat and all kinds of contaminants (breading, batter, crumbs, marinades, ice particles from frozen food etc.) reducing its lifetime. To extend frying oil service life filtration is the most important step. It helps to control consistency of food and keeps operational costs down.

These are the common methods applied to frying oil.
Frying Oil Passive Filtration

Passive Filtration

Surface filtration / Passive filtration removes particulate from the oil through sieving. This is the method commonly referred to simply as “filtration”. Examples of passive systems are filter paper, bag filters and steel screens (mechanical removal of solids). This is anything from 2 mm to 4 mm screens down to typically 50 microns. These systems remove only the insoluble particulates of certain sizes. 

depth filtration pads

Depth Filtration

Depth filters consist of a relatively thick layer of porous materials containing irregular and tortuous channels.  Particles are entrapped within this matrix.  Depth filters have greater porosity than passive filters and are not “blinded” (reducing or shutting off pores, thereby shutting off flow through the filter) as easily as passive filters. The increased depth of the filter media allows multiple stages of filtration.

  1. arger solids are held on the surface of the pad.
  2. Smaller solids are trapped within the structure. The structure has a very high number of internal pores, it holds a high degree of solids.
  3. The internal structure gets thighter the further you travel through the pad ensuring even the finest solids are trapeed.
Frying oil filtration with active powder, activated carbon

Active Filtration or Treatment

These filters include active materials such as adsorbent powders and activated carbon. Besides the before described surface and depth filtration. Filters with active powders (e. g. filter pads) remove and reduce metallic ions, soaps, color, odor, off flavors and even finer particulates suspended in the oil. The removal of these contaminants, help to extend the service-life of frying oil.

Efficient and Effective Combinations

The combination of depth and active filtration are the most efficient frying oil filtration media. They combine a fine filtration with treatment of the oil and do not only remove small particles, but also suspended contaminants. The combination of depth filtration and treatment results in the highest frying oil service-life and costs savings.

frying oil management

Important Note

For successful frying-oil-management, it is important to filter regularly. Filter frying oil twice a day should be the minimum to succeed in slowing down the oil-degradation process.
