Studies on Emu Oil

Despite the fact that it is an oil, emu oil benefits us in so many ways. Emu oil has been shown in tests to be a non-pore-clogging substance. In a 2 week study of arthritis sufferers, 7 out of 12 emu oil users reported a significant reduction in pain, morning stiffness and swelling. A Boston University study found a 20% increase in growth activity of the skin in a two week study of mice. They also found an enhancement in growth activity of the hair follicles. Another study with elderly women showed in one month’s usage of emu oil daily, the skin wall thickened by 14%. By having thicker, healthier skin, the opportunity for bruising lessened. Age spots also tended to fade, and in some cases, completely disappeared. An Australian study followed 500 people over a 10 year period and noted that there had never been any allergic reactions from emu oil reported.

Other benefits from this study are summarized in three areas:

Skin
• Eczema - reduce irritation and inflammation of the skin
• Keloids - significantly reduces recent keloid scarring
• Burns - appears to promote faster healing with less pain and scarring
. Donor sites in skin grafting – reduced pain and less scarring
• Psoriasis - limited benefit in some patients

Recent Wounds

• Epithelialized wounds - reduced scar tissue formation, soothing of wounds after surgery by anti-inflammatory action. Joints

• Joint pain - reduced pain, swelling, and stiffness most evident where the Joint is close to the skin surface, such as hands, feet, knees, and elbows

• Bruising and muscle pain - significant benefit to recent bruising and muscle pain where injury is relatively superficial. Significant reduction in sports related muscle strains post-exercise emu oil massage. A nine month study of 10 burn patients at a burn center in Texas showed that patient comments almost unanimously favored emu oil as an end result and during application.

There was also a unanimous difference noted in photographs taken of the wounds as far as reduction in scarring and inflammation in control areas treated with emu oil. Many chiropractors and physical therapists are using emu oil in their practices. Relief is quicker and muscles stay relaxed longer, therefore treatments last longer.

Emu oil appears to be one of the undiscovered secrets of the modern world. As a natural ingredient that has enjoyed a treasured place among the ancient peoples of Australia for centuries, it has just begun to share its benefits to the industrialized world in the last decade. This natural remedy has already found a place in the international cosmetic marketplace and a research and marketing by companies who have identified

its beneficial value are racing for the lead in a competitive marketplace.

A growing cache of testimonials, research data, and unmistakable benefits from the oil has lead to an exploration of a myriad of commercial applications. It has invited the scrutiny of the medical profession, the scientific community and the health-conscious consumer to explore the health related aspects of the oil. It shows promising benefits as an organic additive in applications as diverse as medicine, food, and even industrial equipment.

This natural substance offers the benefits of pain relief without the side effects of harsh drugs. No other oil offers the versatility of emu oil.

Emu Oil Processing Details

INTRODUCTION

Production of emu meat and oil has been steadily increasing in recent years, and both products are starting to be studied in more depth. Some data has already been published on the properties of the oil; however, there are still some discrepancies on some of its measured characteristics. Some of these discrepancies are due to differences in methods of measurement and the source of the oils.

There are no established methods to process the emu oil in particular; however, the technology to recover and refine this oil is readily available. This paper will comment on some of the properties of the oil that have been published in literature and also will include some of the methods commonly practiced in the industry to extract and refine emu oil.

PROCESSING

Due to the nature of emu oil, rendering and refining practices of this oil have to take into account the fact that this oil is more susceptible to spoilage than the usual rendered animal fats such as lard or tallow. Modern technology and equipment to render animal fats are readily available and can be easily adapted to processing emu oil Extraction and refining of emu oil have to be carried out under moderate conditions of temperature and minimal exposure to air. This makes it necessary to study different processing parameters such as temperature and the use of nitrogen to provide and inert atmosphere.

Extraction of Emu Oil – There is not a single method to render emu fat. This industry is relatively young; therefore, manufacturers are using rendering methods that they consider best for their needs. However, some generalizations can be made as to the process of rendering. Figure 1 outlines some of the operations involved in rendering.

1. Washing

Removal of fatty tissue from the emu carcass is relatively easy and usually no special equipment is necessary to separate the fat from the muscle tissue. However, it is particularly important that the fatty tissue be clean and devoid of dirt and contaminants such as blood, feathers, or manure. Once the fatty tissue is removed from the carcass, the washing step can be carried out manually, or in larger operations with the use of washing sprays and conveyor belts. In conventional operation the water used is 120-140 deg F.

2. Cooking

In this operation the fat is removed from the fatty tissue by breaking the fat cells through application of heat. This softens the tissue and allows the fat to break free. Here temperature and exposure to air are critical. It is recommended that, regardless of the cooking method, the cooker be blanketed with nitrogen to prevent oxidation from the presence of air. Two methods are generally used in this operation, namely wet rendering and dry rendering. In wet rendering, the fatty tissue is charged into the closed or open tank and boiling water is added. The hot water helps break the fat cells and the liquid fat comes to the surface where it is separated and then washed with a weal acid solution.

In dry rendering, the fatty tissue is heated in a jacketed closed vessel. The fat cells are ruptured by dehydration and the fat is released as the moisture evaporates. Cooking operation under vacuum is reported to reduce the cooking time and spoilage of the final product. This operation is conducted at 180 – 250 Deg F. In the case of the emu oil, it is up to the manufacturer to chose the processing temperature, taking into account that the higher the temperature the higher the yield in oil, but also lower the quality of the final product due to overexposure to heat.

3. Fat Separation

Fat generated in the cooker is then filtered to further eliminate contaminants and this is done in several ways. A simple way is to allow solids to settle and then separate the fat fraction by decanting. This method is time consuming and not very effect for larger operations. Other ways to separate solids from the fat released in the cooker is hydraulic press, screw press and centrifuging. The chosen method will depend on the nature of the recovered fat and the size of the operation.

4. Fat Washing

This operation is carried out to coagulate and separate protienaceous components of the recovered fat and can be done by simple water washing, steam coagulation, phosphate (trisodium phosphate) washing, citric acid washing or a combination of these methods. This operation will depend on the amount of un coagulated protein in the fat and it is usually done at temperatures below 210 deg F. Coagulated material usually settles rapidly, and its removal is done in settling tanks, Washed fat is then filtered to remove any remaining suspended particles before going into the dryer. This is usually done in a filter press it the use of a filter aid such as diatomaceous earth, which is added to facilitate passage through the filter cloth. Another way to separate suspended solids in the washed fat is the use of disk – type, self-cleaning centrifuges. Centrifuges are more expensive and are usually used in larger operations.

5. Fat Drying

Water present in the fat, particularly in the presence of air, will cause the fat to deteriorate rapidly. Therefore, it is important that the oil be dried immediately after the washing step. Moisture removal is usually done by flash drying. The washed fat is first rapidly heated (up to 240 deg F) and then pumped into a tank where the water flashes out from the fat. The vapour thus generated is condensed and collected in a different thank. This operation can be done at the lower temperature if vacuum is used.

Refining of Emu Oil

The oil generated in the extraction operation may be high in free fatty acids, peroxides, and other impurities and also may have unpleasant odors. This makes it necessary to further process the oil to make it fit for the use as an edible product or for use in cosmetics or pharmaceuticals. The presence of metals in rendered fats in general is unavoidable due to contact of the fat with blood tissue. Metals are very effective catalysts in the generation of free fatty acids from triglycerides and rapidly generates rancidity in crude or finished oil.

Free fatty acids formed further deteriorate into peroxides which themselves decompose into odorous materials which give the oil from the rendering operation an unpleasant smell. Decomposition of proteinaceous materials, particularly if the bacterial count is high, also generates obnoxious smells. This makes it necessary to follow some or all of the following refining treatments in order to bring the oil to the desired specifications of a final product. To what extend the oils should be refined will depend on its initial quality and on its final use, i.e., cosmetics, pharmaceuticals, or food.

1. Caustic neutralization

This operation is carried out to remove free fatty from the original fat and are not harmful per se. However, they are precursors of peroxides and carboxylic compounds that are responsible for unwanted odors and rancidity in fats, and their removal is usually the first step in refining process. This is usually done by neutralizing the free fatty acids with a weak caustic solution (10-15%) and adding a slight excess to ensure complete neutralization. The neutralized free fatty acids are then easily removed by centrifugation as saponified matter; this step also removes residual matter such as phosphorous-based gums commonly in crude oils and any uncoagulated protein that may have remained in the oil from the rendering operation

After the oil has been neutralized and centrifuged, it is usually washed with de-ionized

Water to remove residual saponified matter and the excess water that remains in the oil is then removed in a flash dryer.

2. Bleaching

This operation is usually practiced to remove unwanted colored compounds in oils. Examples of these color compounds are carotenoids, chlorophyll, and burnt or polymerized matter. An acid-activated clay is usually used for the removal of these colored compounds. However, bleaching also serves as a ‘cleaning’ step of other contaminants.

The acid-activated clay, in conjunction with other adsorbents normally used for bleaching, also serves as a catalyst to decompose or remove peroxides and metals that may still be present in the oil. In the case of emu oil, the bleaching operation is seldom used to remove color. Emu oil extracted under moderate temperature and minimal exposure to air usually has an acceptable color. However, the oil may still have some metals and an excess of peroxides and saponified matter that must be removed from the oil. The adsorbents used in bleaching effectively remove these contaminants. It is extremely important that most metals be removed before processing the oil any further. The next step is usually deodorizing, and if any metals are present in the oil during deodorizing, it may in fact worsen the quality of the final product.

3 Deodorizing

This operation is performed to remove odors, peroxides, and carboxyl compounds from the bleached oil. In some cases, this step is used to remove free fatty acids as well. If the starting oil is good quality, the neutralization step with caustic solution may be avoided, and the deodorizer can be used also as a physical refiner.

Deodorizing is usually done by injecting pure steam into the heated oil (350-450 deg F) under high vacuum (2-4mm HG). The resulting oil from this step is also usually devoid of peroxides and short chain carboxyl compounds. Table1 lists some typical characteristics of the deodorized oil with regard to the free fatty acids, color and other specifications typically measured to assess the quality of the finished oil. Usually, this is the last step in processing an oil at the end of the deodorizing step, and antioxidant is added to the final product such as BHT or tocopherols which will retard spoilage and allow a longer shelf life. Metal scavengers such as citric acid (0.01%) are also added during the cooling period of the deodorization process.

4 Winterization

After several days in storage, emu oil will develop two layers: a Bottom layer of high-melting stearins and upper layer of lower melting, more unsaturated oleins. He properties of these two layers have not been studied in depth, but in the case of oils such as cottonseed or sunflower, the development of a searin fraction is considered unsightly. If the oils are intended as salad oils, they are chilled (usually at 40 deg F), and the stearin formed is removed by filtration. The resulting oil is now devoid of turbidity and is what is called a clarified salad oil. In the case of emu oil, this operation can also b performed if the objective is to produce a clear product.

The oil resulting from the chilling process will have a slight different fatty acid profile. If the final objective is to preserve the same fatty acid composition but also an oil that will not separate into two phases, a process of randomization can be conducted.

5. Randomization

Separation of a solid and clear phase in edible oils can be prevented by randomization. Since this separation is due to a difference in composition of the stearin (richer in saturates) and olein (richer in unsaturates), rearranging the distribution of the fatty acids in the triglyceride molecules would make the overall distribution of fatty acids more uniform and therefore no phase separation occurs. Randomization does not change the overall fatty acid composition of the oil. This operation is carried out with the aid of a catalyst such as Na ethoxide and is usually done at mild temperatures (70-90 deg F). This operation is commonly practiced in processing other rendered fats such as lards and tallow.
