Margarine production process description. The margarine production process consists of five sections: the oil phase with emulsifier preparation, the water phase, the emulsion preparation, pasteurization and crystallization. Any excess production is returned via a continuous rework unit to the emulsion tank.

What chemicals are used to make margarine?
Soybean oil is the most common base in U.S. margarines; manufacturers also use sunflower, corn, palm, safflower, cottonseed, peanut, and canola oils.
Why is hydrogen used to make margarine?
Fat hydrogenation is the process of combining fat—typically, vegetable oils—with hydrogen, in order to make it more saturated to produce solid or semi-solid fats, such as those present in margarine.
Why hydrogen is used in making margarine?
Specialty oils and fats in margarines and low-fat spreads Hydrogenation is a chemical process that adds hydrogen to the unsaturated bonds on the FA chains attached to the TAG backbone. In this way, an unsaturated fat can be turned into a saturated fat and increase its melting point (List and King, 2006).
How is margarine made from vegetable oil chemistry?
This is called hydrogenation. It includes the manufacture of margarine from animal or vegetable fats and oils. Ethene reacts with hydrogen in the presence of a finely divided nickel catalyst at a temperature of about 150°C. Ethane is produced.
What is the raw material for margarine?
The raw materials for the manufacture of margarine are vegetable oils such as palm, sunflower, rape seed and soya bean oils. Vegetable oils contain triglyceride esters derived from propane-1,2,3-triol (glycerol), and unsaturated carboxylic or fatty acids.
Which gas is used to manufacture margarine?
Hydrogenation. 2 The oil is then hydrogenated to ensure the correct consistency for margarine production, a state referred to as “plastic” or semi-solid. In this process, hydrogen gas is added to the oil under pressurized conditions.
Which metal is used as a catalyst in the manufacture of margarine?
Nickel is used in the production of margarine as a catalyst for hydrogenation. This may lead to the presence of its residues in the products and could cause allergic reactions. Therefore, monitoring of this metal in foods is essential for consumers. The described liquid sampling AAS procedure allows product control.
What happens when bromine reacts with margarine?
Unsaturated fatty acids in the oils and fats of margarine and butter will decolourise bromine water. The reaction is quantitative – 1 mole of C=C bonds will react with 1 mole of bromine, Br2, and will self-indicate during a titration.
What type of mixture is margarine?
Margarine consists of a water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase in a stable solid form.
Is margarine polar or nonpolar?
Emulsification to Combine Oil and Water: Two of the first ingredients in margarine are water and oil. These liquids are immiscible; this because water is a polar molecule, meaning that the charges are asymmetrically shared, and oil is a nonpolar molecule, meaning the charge of the molecule is equally distributed.
Why margarine is produced?
Margarine was invented in France by Hippolyte Mège-Mouriès in 1869, during the Franco-Prussian wars. He invented it in response to a competitive challenge from the French government under Napoleon III, who was looking for a cheap and stable substitute for butter, and offered a big prize to anyone who could pull it off.
What is the difference between margarine and butter?
Butter is made from heavy cream. It contains higher levels of saturated fat, which can lead to several risks. Margarine is made from vegetable oils. It contains unsaturated fats that serve as “good” fats in the body.
Is ammonia used in production of margarine?
The crystallization line for the production of margarine and related products typically consists of a high pressure SSHE which is cooled by ammonia or Freon type cooling media.
Why is margarine an emulsion?
There are two types of emulsions. The first is when water gets dispersed into fat/oil (such as butter, margarine or chocolate) and the second is when oil/fat gets dispersed in water (such as milk, mayonnaise, or salad dressing).
How do you harden margarine?
How are unsaturated compounds in plant oils used to make margarine?
Hardening unsaturated vegetable oils Unsaturated triglycerides can be ‘saturated’ by chemically adding hydrogen (heating with hydrogen gas, in the presence of a nickel catalyst, to 60ºC) to the C=C double bond: this process is called hardening and makes it the triglyceride more solid-margarine is made this way.
How does the bromine test work?
The bromine test is used to test for an unsaturated carbon carbon bond, such as an alkene or alkyne. The test uses a type of chemical reaction called addition, where a reactant, here bromine, is added to an organic compound to break a double or triple bond.
What happens when bromine water is added in excess?
Adding excess bromine water to the compound will result in Bromination and will give a white precipitate.
What is the characteristic of margarine?
The most important functional characteristics of margarines are spreadability, oil separation and melting temperature. Oil separation also referred to as oil-off occurs when the type and size of the fat crystals are not sufficient to hold the liquid oil in the matrix.
Is margarine a compound element or mixture?
A homogeneous mixture is a uniform mixture consisting of only one phase. Examples are gasoline and margarine.
Does margarine dissolve in water?
The answer for the given questions, Margaret dissolves easily in oils and Margaret does not dissolve in water. The reason here is marguerite is reaching poly and saturated and mono unsaturated fatty acids hints. It is able to blend easily in oils in comparison with water.
Why does margarine melt faster than butter?
Butter will usually solidify around 60-65°F. The melting point of margarine is slightly higher than butter because of the presence of hydrogenated fats. It melts at 94-98 °F.
Is margarine solid or liquid?
According to the FDA Code of Federal Regulations (a resource which lists out what foods must have or not have in order to claim themselves as certain things), margarine is a food in plastic form (meaning it’s not solid, not liquid) or a liquid emulsion, containing not less than 80% fat… and contains only safe and …
How is margarine made solid?
The solid fat can be made by total hydrogenation of a vegetable oil such as soybean oil. Total hydrogenation gets rid of all the double bonds and does not produce any trans fats. An enzyme, known as a lipase, isolated either from a fungal or bacterial source, is added to the mix of solid and liquid fats.
