Instrument Description

General Description

The ANKOM petroleum ether. The compounds extracted are primarily triacylglycerols together with a small quantity of related lipids, traditionally termed “Crude Fat.” The analysis is achieved by measuring the loss of mass due to the extraction of fat/oil from the sample encapsulated in a filter bag. The quantitative isolation of the sample is accomplished by surrounding the sample in a sealed filter bag with a filtering capacity in the 2 to 3 micron range. The filter bag has sufficient porosity to permit rapid solvent passage and is composed of polymeric material that is resistant to the higher temperatures and solvents used in the instrument.

The quantitative isolation achieved by the filter bag permits the ANKOM process samples in batches of up to 15. With the solvent reservoir filled, simply place filter bags with sample in the Extraction Vessel, lock the vessel in place, select the extraction time and temperature, and press “Start.” The instrument will automatically fill the Extraction Vessel with solvent, extract the fat from the sample, and recycle the solvent.

Below is a detailed view of the ANKOM

Flammable Hazard: Static electricity is to be avoided as it is a spark hazard.

Hot Surfaces: Do not touch the extraction vessel during operation. The surface

can exceed 70°C (158°F). Failure to observe this caution may result in injury.

Hazardous Voltages: Do not operate the instrument with the electrical compartment open. Hazardous voltages are present during operation. Failure to

observe this caution may result in electrical shock or electrocution.

Hazardous Materials: The ANKOM

XT15

Extraction System comes equipped with a charcoal filter which traps any residual vapor in the vent system. By properly maintaining the charcoal filter, volatiles will not escape the vent system. We recommend replacement of the filter every 3 months or after 100 extraction runs. Trace amounts of vapor may also be present when samples are removed. It is recommended that the ANKOM

XT15

Extraction System be placed in a well ventilated environment, away from any heat or ignition sources. Organic solvents may be flammable. Follow safe laboratory practices according to both local and federal regulations when installing this instrument and when handling any organic solvents.

WARNING: Attempts to override safety features or to use this instrument in a manner not specified by ANKOM Technology voids the warranty and may result in serious injury or even death.

This system is designed to meet and/or exceed the applicable standards of CE, CSA, NRTL and OSHA.

Please review the entire contents of this manual before you begin operating this instrument.

Safety Precautions

pg. 8 Rev F 12/08/14

Page 9

Operator’s Manual

Remove the instrument from the shipping container and place in an area that is free of dust and excessive moisture, and is well ventilated (away from any heat or ignition sources).

Because the ANKOM

XT15

Extraction System is a closed system, there is very limited exposure to solvents. When used in conjunction with a charcoal filter on the vent line the instrument produces less than 1ml of volatiles. It is the user’s responsibility to determine whether venting of this instrument requires placement in a hood. Please follow both local and federal regulations when installing this instrument.

Connect the tube from the top fitting to the water supply and the one from the bottom fitting to the drain.

Ensure that there are no kinks or bends in any of the tubing connected to the instrument.

Connect the vent flask to the Vent Flask Connector on the instrument and run the tubing to the inline charcoal filter. Periodically check the vent line to verify that it is free from any blockage or kinks. Generally, there should not be any significant solvent in the vent flask. Any solvent visible in the flask may indicate a problem with the water supply to the instrument.

Change the Charcoal Filter every 3 months or after 100 extraction runs.

Plug the power cord into a grounded receptacle.

Crude Fat contained within a food or feed sample can be calculated using the following formula:

% Crude Fat

100 x (W2 – W3)

Where:

W1 = Original weight of sample

W2 = Weight of pre-extraction dried sample and filter bag

W3 = Weight of dried sample and filter bag after extraction

For Liquid Samples, W2 and W3 in the equation above will include the weight of Diatomaceous Earth (DE). For Meat Samples with > 15% fat and plant samples with > 20% fat:

% Crude Fat

100 x ((W2 – W4) – W3)

Where:

W4 = Weight of the weigh tin

If hydrolysis is done prior to fat extraction, then Total Fat contained within a food or feed sample can be calculated using the following formula:

% Total Fat

100 x (W2 – (W3 + (C1 – C2)))

Where:

W1 = Original weight of sample

W2 = Weight of dried sample, filter bag, and Diatomaceous Earth (DE) after hydrolysis

W3 = Weight of dry extracted sample, filter bag, and DE

C1 = Blank filter bag dry weight after hydrolysis

C2 = Blank filter bag weight after extraction

The Hydrolysis procedure can be found in the ANKOM HCl Operator's Manual.

To prepare meat samples with ≤ 15% fat by weight or plant samples with ≤ 20% fat by weight for fat extraction, follow the procedure detailed below.

Using a Solvent Resistant Marker, number all of the empty filter bags you will use during the fat extraction procedure. Although it is not necessary in the determination of fat, it is recommended that you weigh and record the weights of all the filter bags prior to filling them in order to calculate the moisture value for the samples.

% Moisture = 100 x ((Filter Bag Weight + Sample Weight) - Weight after drying)

Sample Weight

Place an empty filter bag in the Bag Holder in an open position.

Tare the weight of the empty filter bag and the holder together.

Add 1.5 – 2g of sample to the filter bag. Keep all particles away from the sealing area of the filter bag.

Record the weight of the sample (W1) and tare.

Set the Heat Sealer dial to 6. (The setting may vary from sealer to sealer.)

Seal the filter bag within 4mm of its open end. Keep the sealer arm down for 2 – 3 seconds after the red sealer light turns off (to cool the seal). The seal can be seen as a solid melted stripe along the top edge of the filter bag (as shown to the right). If the seal is not strong, re-seal the bag.

Repeat steps 1 – 7 for all filter bags that will be used in the ANKOM

XT15

Extraction System. (Up to 15

bags can be processed during one procedure.)

Dry all samples at 102°C±2° for 3 hours to remove moisture prior to the extraction.

10.

Remove the samples from the oven and place them in a Desiccant Pouch.

11.

Allow the samples to cool to room temperature. This should take about 10 – 15 minutes.

12.

Re-weigh each bag (W2) immediately after removing from the Desiccant Pouch.

The samples are now ready for the fat extraction procedure.

Periodic Maintenance

Cleaning the Extraction Vessel

Some compounds extracted during the fat extraction procedure can create a black residue in the bottom of the Extraction Vessel. The vessel can most easily be cleaned by using a drill with a long shafted stiff wire brush (ANKOM part # X107). This treatment will remove a lot of the black coating that accumulates on the bottom of the vessel. When the vessel bottom is clean, put some solvent on a cloth or paper towel and wipe down the inside of the vessel in an effort to remove any oil residue and particles that have been loosened from the vessel bottom.

Cleaning the exterior of the instrument

Wipe the outside of the instrument with window cleaner or a damp sponge as necessary.

Cleaning the solvent filter

If filter bags are not sealed properly and sample is lost from the bag, it will be recovered in the solvent filter in the exhaust line.

ANKOM Technology Method

AOCS Official Procedure Am 5-04

Rapid Determination of Oil/Fat Utilizing High Temperature Solvent Extraction

Definition

This method determines crude fat by extracting with petroleum ether. The compounds extracted are predominantly triacylglycerides. Small amounts of other lipids along with minor compounds having some solubility in petroleum ether are also extracted.

Scope

This method is applicable to solid processed foods with 0-100% fat content.

Apparatus

1. Analytical Balance—capable of weighing 0.1 mg.

2. Oven—capable of maintaining a temperature of 102 ± 2°C.

3. Extraction instrument—capable of extracting at 90 ± 2°C.

(XT10, XT15, XT20, ANKOM Technology).

4. Filter Bags—constructed from chemically inert and heat

resistant filter media, capable of being heat sealed closed and able to retain 1 micron particles while permitting solution penetration (XT4, ANKOM Technology).

5. Heat sealer—sufficient for sealing the filter bags closed to

ensure complete closure (1915, ANKOM Technology).

6. Desiccant Pouch—collapsible sealable pouch with desiccant

inside that enables the removal of air from around the filter bags (MoistureStop weigh pouch, ANKOM Technology).

7. Marking pen—Solvent and acid resistant (F08, ANKOM

Technology).

8. Dryer (optional)—forced air dryer capable of maintaining a

temperature between 60-120°C (ANKOMRD Dryer, ANKOM Technology).

Reagents

1. Petroleum Ether (B.P. 35-65º C). Depending on the method

used, other solvents such as hexanes and ethyl ether may be used. CAUTION: Most fat solvents are extremely flammable. Avoid static electricity and follow safe laboratory practices according to your local regulations when handling solvents.

Precision

Results from the collaborative study (see Table 1) indicate the precision (Sr, RSDr, r) that the analyst should use as a benchmark for evaluation replication in the same laboratory.

Procedure (see the Fat Extraction Process section of the Operator’s

Manual for more detail)

1. Place a labeled filter bag on the balance and zero the balance.

2. Weigh 1.5 – 2g of sample into the bag and record the weight

(W1).

3. Heat seal the filter bag closed within 4mm of the top to

encapsulate the sample.

4. It is good practice to include a blank bag periodically,

especially when changing solvents, in order to measure any effect on the filter bag.

5. If a meat sample has an expected fat value of > 15% or a plant

sample has an expected fat value of > 20%, then place the filter bag with sample in a tared weigh tin (W4) during the oven drying procedure in order to capture fat that may migrate out of the bag during heating.

6. Place samples in the drying oven at 102 ± 2°C for 3 hrs (see

Numbered Note 1).

7. Cool the dried samples in the Desiccant Pouch, weigh and

record the weight (W2).

8. Place filter bags with sample into the bag holder and place in

the extractor.

9. Follow the extraction instrument instructions.

10. When the extraction process is complete dry the samples for

15 – 30 minutes in the oven at 102 ± 2°C or in the ANKOMRD Dryer set at the factory setting of 110°C. (See Numbered Note

2.)

11. Cool in the Desiccant Pouch and weigh (W3).

Calculations

Meat samples ≤ 15% fat and plant samples ≤ 20% fat

Meat samples > 15% fat and plant samples > 20% fat

% Crude Fat

100 x (W2 – W3)

% Crude Fat

100 x ((W2 – W4) - W3)

Where:

W1 = Original weight of sample

Where:

Weight of the weigh tin

W2 = Weight of pre-extracted dried sample with filter

bag

W3 = Weight of dry sample with filter bag after

extraction

NOTE: For Liquid Samples, W2 and W3 in the above equations will include the weight of Diatomaceous Earth (DE).

Numbered Notes

1. Pre-extraction drying time of the samples in the filter bags can be greatly reduced by using a microwave oven. However,

microwave ovens vary in energy output and samples vary in water and fat composition. You will need to experiment with your microwave oven to determine the proper conditions for use. Contact ANKOM Technology for further information.

2. Some samples with large amounts of carbohydrates (starches and cellulose) may bind small quantities of solvent and require

additional post drying. To remove bound solvent, dry at 100°C for 1 – 3 hrs or at 125°C for 30 minutes.
