Manufacture margarines

In many countries these proportions are controlled by legislation. Gums and thickeners such as gelatin, alginates and most commonly, caseinates are used to replace the viscosity and bulking effect of the fat and to ensure that a stable water-in-oil emulsion is formed. Manufacturing process varies according to ingredients used and product formula, however, a typical process can be summarized as follows:. A Silverson High Shear mixer is able to overcome all of these difficulties. This is typically achieved using an In-Line mixer operating in conjunction with an in-tank agitator as follows:. The aqueous phase ingredients are added to the vessel and recirculated through the self-pumping In-Line mixer which disperses and hydrates the materials, rapidly producing a homogeneous agglomerate-free mix.

Butter and Margarine

Margarine : Is a spread used for spreading, baking, and cooking. Margarine is made mainly of hydrogenated or refined plant oils and water. While butter is made from fat from milk, margarine is made from plant oils and may also contain milk.

In some locales it is colloquially referred to as "oleo", short for oleomargarine. Margarine, like butter , consists of water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase which is in a stable crystalline form. Margarine can be used both for spreading and for baking and cooking.

It is also commonly used as an ingredient in other food products, such as pastries and cookies, for its wide range of functionalities.

The basic method of making margarine today consists of emulsifying a blend of hydrogenated vegetable oils with skimmed milk, chilling the mixture to solidify it and working it to improve the texture. Vegetable and animal fats are similar compounds with different melting points. Those fats that are liquid at room temperature are generally known as oils.

The melting points are related to the presence of carbon-carbon double bonds in the fatty acids components. Higher number of double bonds give lower melting points. Partial hydrogenation of typical plant oil to a typical component of margarine. Commonly, the natural oils are hydrogenated by passing hydrogen through the oil in the presence of a nickel catalyst, under controlled conditions. This is due to the increase in van der Waals' forces between the saturated molecules compared with the unsaturated molecules.

However, as there are possible health benefits in limiting the amount of saturated fats in the human diet, the process is controlled so that only enough of the bonds are hydrogenated to give the required texture. Margarines made in this way are said to contain hydrogenated fat. This method is used today for some margarines although the process has been developed and sometimes other metal catalysts are used such as palladium.

If hydrogenation is incomplete partial hardening , the relatively high temperatures used in the hydrogenation process tend to flip some of the carbon-carbon double bonds into the "trans" form. If these particular bonds aren't hydrogenated during the process, they will still be present in the final margarine in molecules of trans fats, the consumption of which has been shown to be a risk factor for cardiovascular disease.

For this reason, partially hardened fats are used less and less in the margarine industry. Some tropical oils, such as palm oil and coconut oil, are naturally semi solid and do not require hydrogenation. Modern margarine can be made from any of a wide variety of animal or vegetable fats, mixed with skim milk, salt, and emulsifiers.

Depending on its final fat content and its purpose spreading, cooking or baking , the level of water and the vegetable oils used will slightly vary. The oil is pressed from seeds and refined. It is then blended with solid fat. If no solid fats are added to the vegetable oils, the latter undergo a full or partial hydrogenation process to solidify them. The resulting blend is mixed with water, citric acid, carotenoids, vitamins and milk powder. Emulsifiers such as lecithin help disperse the water phase evenly throughout the oil, and salt and preservatives are also commonly added.

This oil and water emulsion is then heated, blended, and cooled. The softer tub margarines are made with less hydrogenated, more liquid, oils than block margarine.

Many popular table spreads sold today are blends of margarine and butter or other milk products. Blending, which is used to improve the taste of margarine, was long illegal in countries such as the United States and Australia. Under European Union directives, a margarine product cannot be called "butter", even if most of it consists of natural butter.

In some European countries butter-based table spreads and margarine products are marketed as "butter mixtures". Butter mixtures now make up a significant portion of the table spread market. These butter mixtures avoid the restrictions on labeling, with marketing techniques that imply a strong similarity to real butter.

Such marketable names present the product to consumers differently from the required product labels that call margarine "partially hydrogenated vegetable oil". Discussions concerning the nutritional value of margarines and spreads revolve around two aspects — the total amount of fat, and the types of fat saturated fat, trans fat. Usually, a comparison between margarine and butter is included in this context as well. Saturated fatty acids have not been conclusively linked to elevated blood cholesterol levels.

Replacing saturated and trans unsaturated fats with unhydrogenated monounsaturated and polyunsaturated fats is more effective in preventing coronary heart disease in women than reducing overall fat intake. See saturated fat and cardiovascular disease controversy. Liquid oils canola oil, sunflower oil tend to be on the low end, while tropical oils coconut oil, palm kernel oil and fully hardened hydrogenated oils are at the high end of the scale.

A margarine blend is a mixture of both types of components. Generally, firmer margarines contain more saturated fat. Consumption of unsaturated fatty acids has been found to decrease LDL cholesterol levels and increase HDL cholesterol levels in the blood, thus reducing the risk of contracting cardiovascular diseases. There are two types of unsaturated oils: mono- and poly-unsaturated fats both of which are recognized as beneficial to health in contrast to saturated fats.

Some widely grown vegetable oils, such as rapeseed and its variant canola , sunflower, safflower, and olive oils contain high amounts of unsaturated fats. During the manufacture of margarine, some of the unsaturated fats may be converted into hydrogenated fats or trans fats in order to give them a higher melting point so that they are solid at room temperatures. Omega-3 fatty acids are a family of polyunsaturated fatty acids, which have been found especially good for health.

This is one of the two Essential fatty acids, so called because humans cannot manufacture it and must get it from food. Omega-3 fatty acids are mostly obtained from oily fish caught in high-latitude waters. They are comparatively uncommon in vegetable sources, including margarine. However, one type of Omega-3 fatty acid, alpha-Linolenic acid ALA can be found in some vegetable oils. Omega-6 fatty acids are also important for health.

They include the essential fatty acid linoleic acid LA , which is abundant in vegetable oils grown in temperate climates. Margarine is very high in omega-6 fatty acids. Modern Western diets are frequently quite high in Omega-6 but very deficient in Omega The omega-6 to omega-- ratio is typically - to -. Large amounts of omega-6 decreases the effect of omega Therefore it is recommended that the ratio in the diet should be less than , although optimal ratio may be closer to Unlike other dietary fats, trans fatty acids are not essential and provide no known benefit to human health.

There is a positive linear trend between trans fatty acid intake and LDL cholesterol concentration, and therefore increased risk of coronary heart disease, by raising levels of LDL cholesterol and lowering levels of HDL cholesterol.

In the US, partial hydrogenation has been common as a result of preference for domestically produced oils. However, since the mids, many countries around the world have started to move away from using partially hydrogenated oils.

Excessive cholesterol is a health risk because fatty deposits gradually clog the arteries. This will cause blood flow to the brain, heart, kidneys and other parts of the body to become less efficient. Cholesterol, though needed metabolically, is not essential in the diet. Therefore overall intake of cholesterol as food has less effect on blood cholesterol levels than the type of fat eaten. However, some individuals are more responsive to dietary cholesterol than others.

The US Food and Drug Administration states that healthy people should not consume more than mg of cholesterol each day. Most margarines are vegetable-based and thus contain no cholesterol. Plant sterol esters or plant stanol esters have been added to some margarines and spreads because of their cholesterol lowering effect. By the end of the 20th century, an average American ate around 5 lb 2.

Margarine has a particular market value to those who observe the Jewish dietary laws of Kashrut. Kashrut forbids the mixing of meat and dairy products; hence there are strictly Kosher non-dairy margarines available. These are often used by the Kosher consumer to adapt recipes that use meat and butter or in baked goods that will be served with meat meals.

The Passover margarine shortage in America caused much consternation within the Kosher-observant community. Margarine that doesn't contain dairy products can also provide a vegan substitute for butter.

Hydrogenated vegetable oil prevents margarine from melting and separating at room temperature. Most margarine is normally made by making an emulsion of skimmed milk and vegetable oil. The first margarine was actually made of mostly beef fat. I, for one, am glad they changed the recipe. You can find more info at:. Margarine is made of vegetable oils which are obtained from plant fats and skim milk. These vegetable oils include corn, cottonseed, soybeans, and safflower seeds.

To make margarine from vegetable oil, start by extracting oil from seeds such as: corn, canola or safflower. The oil is steamed to destroy antioxidants and vitamins.

Next, the oil is mixed with a highly toxic substance called nickel, which acts as a catalyst. You will then put the oil in a reactor, under very high temperatures and pressure through a process known as emulsification hydrogenation. Emulsifiers are added to the oil so as to remove the lumps and the oil is steamed again. Bleaching is done so as to get of the grey color and synthetic vitamins and artificial colors are added.

Vegetable oils are made either cold-pressed such as olive and sesame, and they are also refined. Refined oils include safflower or canola. There are a variety of oils that are used in food preparation and recipes. Vegetable oils are categorized as to their origin, and cooking temperature.

Production of Margarine and Low Fat Spreads

The global industrial margarine market is anticipated to reach USD 2, This is primarily attributed to the increasing consumption of margarine, growing bakery and confectionery industry, and its low price. Margarines are foodstuffs that are used mainly for spreading, baking, and cooking processes. Margarines are rich sources of fat and provide energy.

Page 1 Page 2 Page 3. It is widely used both as a spread and as a cooking fat.

The association was established in Is that true? If we compare Turkey to the rest of the world, the margarine industry, as in many branches of industry in Turkey, is competing with its counterparts, and even surpassing them in some cases. A large part of the margarine industry uses modern technology and the sector is thriving. Margarine has been produced for years.

How to successfully manufacture a low fat margarine spread with only 10% fat

It is a well known fact that consumers are requesting healthier foods with an increasingly lower fat content. This is also true for margarine spreads. This article explains how the emulsifier system works, but equally important it also explains how to get the correct processing conditions. Traditionally margarine, dairy and other spread producers have been cautious about developing and producing low fat spreads due to the problems it could generate in the production, such as an increased risk of unstable products and insecure production parameters. The fact is that there is an increasing focus on fat reduction from a nutrition point of view due to the increasing number of people with a BMI above 30 and the subsequent potential risk of coronary heart disease, diabetes etc. At the same time the total cost of raw materials for low fat spreads are lower than for normal margarines. Why not just leave out the spread and make a healthier sandwich? Because the spread has a positive influence on the overall eating quality of the sandwich. As the sandwich is eaten the spread will be mixed with the crumb structure during the chewing and give a better mouth-feel and swelling. At the same time it will improve the mouth-feel and flavour release.

Is This Really How Margarine Is Made?

Fat Production and Consumption pp Cite as. Margarine is an engineered product invented in at a time when demands were high for oils and fats because of a butter shortage in Europe. Its evolution to the present day nutritious spread is a prime example of the technological advancement made in the food industry through the efforts of food technologists, oil chemists, nutritionists, and chemical engineers. It has taken its place world wide as an excellent nutritive food because of its concentrated source of food energy, its uniform supplement of vitamins A and D, its high content of polyunsaturated essential fatty acids, its satiety value and its appetizing flavor and complementary effect it has on other foods.

The group of inventions relates to the oil and fat industry, to the production of edible fatty foods suitable for the preparation of yeast, puff and shortcrust pastry, suitable for use in various creams and fillings, and also suitable as an alternative to butter. To prepare this product, a fat base is used, which is cooking oil, the composition of which includes MOH salomas of indefinite quantitative composition, while the proposed product uses refined deodorized salomas MZ-1 of a certain quantitative composition.

Butter is made from the butterfat of milk, whereas modern margarine is made mainly of refined vegetable oil and water. In some places in the United States, it is colloquially referred to as oleo , short for oleomargarine. Due to its versatility, margarine can be used as an ingredient in other food products, such as pastries, doughnuts, cakes and cookies.

Margarine Production in the U.S.A. and Its Nutritional Contribution to Man’s Diet

Margarine : Is a spread used for spreading, baking, and cooking. Margarine is made mainly of hydrogenated or refined plant oils and water. While butter is made from fat from milk, margarine is made from plant oils and may also contain milk.

Consumption of margarine has steadily--and rampantly--increased since it was concocted by French pharmacist Hippolyte Mege for butter-short troops during the Napoleonic Wars. In fact, much to the continual chagrin of farmers and their cows, we now consume twice as much margarine as butter. The plenitude has wrought confusion, however. Margarine manufacturers have found a timely niche because of the national fixation over fat and cholesterol. Via label claims and television advertisements, we are led to believe there are distinctions that may mean the difference between a prudent purchase and a poor one. In fact, most margarine-type products are surprisingly similar.

How is margarine manufactured?

This page looks at the reaction of the carbon-carbon double bond in alkenes with hydrogen in the presence of a metal catalyst. This is called hydrogenation. It includes the manufacture of margarine from animal or vegetable fats and oils. Ethane is produced. This is a fairly pointless reaction because ethene is a far more useful compound than ethane! However, what is true of the reaction of the carbon-carbon double bond in ethene is equally true of it in much more complicated cases.

The source of these fats can be dairy products, animal fats, or various vegetable oils. With some caveats, this description is not all that far from the truth: several vegetable components have been used in the production of oils used in the manufacturing of margarine. These oils likely would have been extracted at high pressure with solvents. The claim that solvents remain in oil after extraction is dubious , as hexane evaporates at well under degrees, but several later steps in the production process occur at higher temperatures.

Butter is a soft, yellow-hued, edible emulsion of butterfat, water, air, and sometimes salt. It is made from the churning of cream and is used as a spread as well as an important ingredient in cooking and baking. Margarine is an inexpensive alternate to butter, made from oil or a combination of oils through the process of hydrogenation.

Margarine is a butter substitute, the composition of which is controlled by law.

It was believed that margaric acid was one of the three fatty acids which in combination formed animal fats. These days, the chains of fatty acids containing 17 carbon atoms present in animal fats are named margaric acid. After the Second World War mixtures of vegetable fats which would substitute butter made from animal fat started to be used. Different varieties of margarine have been produced depending on what they are going to be used for: stick margarine, spreading margarine, table margarine, etc.

- Вот откуда шрам. - Весьма сомнительно, чтобы Танкадо связал свои ощущения с выстрелом. - И все же он отдал кольцо, - сказал Фонтейн.

- Вы правы, сэр. Но он не искал глазами убийцу.

Говорите. - Где мой ключ? - прозвучал знакомый голос. - Кто со мной говорит? - крикнул Стратмор, стараясь перекрыть шум.
