Do all commercially available oils contain trans fatty acids?

However, trans fatty acids may be found in vegetable oils, such as refined vegetable oils.

Refined vegetable oil may contain trans fatty acids, but it is not inevitable, depending on the refining process, process hydrogenation or high temperature may produce trans fatty acids. Refined vegetable oil is a large range, and salad oil for daily consumption also falls under the category of refined vegetable oil. The explanation of the entry is too absolute and not so correct.

Almost all packaged foods that use oil are made with refined vegetable oil, so there is no need to worry about this in the ingredient list. However, I would like to add that gutter oil with Chinese characteristics.

Sometimes it changes to refined vegetable oil.

Contains trans fatty acids, and it is important to note that the ingredients appear in the following faces:

Hydrogenated vegetable oil, semi-hydrogenated vegetable oil, margarine (milk) oil, artificial vegetable yellow (milk) oil, artificial fat, shortening.

or non-dairy creamer (from Encyclopedia), fresh milk oil, non-dairy cream, margarine (malice).

Palm oil. After hydrogenation and other processes, it is possible to change the order of its carbon chain, and trans fatty acids appear, but generally do not appear, and even if they appear in hydrogenated oil, the content is also low, and the corresponding content of cakes and non-dairy creamer produced by using this type of oil is lower, and there is no harm to the human body after eating.

Consumers don't have to talk about the discoloration of "hydrogenated vegetable oil". Consumers should pay attention to two points about "hydrogenated vegetable oil": first, "hydrogenated vegetable oil", that is, margarine, shortening, etc., cannot be completely equated with trans fatty acids, and hydrogenated vegetable oil with improved process can reduce trans fatty acids, or even do not contain trans fatty acids.

Second, the content of "trans fatty acids" in food should be limited, but it is not necessary to ban the use of hydrogenated vegetable oils in the United States and Denmark.

There are no restrictions on the use of hydrogenated vegetable oils, and it is only recommended that the average daily intake of trans fatty acids by residents should not exceed 1% of total energy.

Vegetable oils are not trans fatty acids. The main components of vegetable oil are linear high-grade fatty acids and glycerol-generated esters, fatty acids in addition to palmitic acid, stearic acid and oleic acid, but also contain a variety of unsaturated acids, such as erucic acid, tung oleic acid, ricinoleic acid, etc., but hydrogenated vegetable oil contains a large number of trans fatty acids.

Vegetable oil is notTrans fatty acids

Vegetable oils are not trans fatty acids. The main components of vegetable oils are straight-chain higher fatty acids and glycerol.

Produced esters, fatty acids except palmitic acid, stearic acid.

In addition to oleic acid, it also contains a variety of unsaturated acids, such as erucic acid, tung oleic acid, ricinoleic acid, etc., but hydrogenated vegetable oil contains a large number of trans fatty acids.

Vegetable oils mainly contain vitamin E

k. Calcium, iron, phosphorus, potassium and other minerals, fatty acids, etc. The fatty acids in vegetable oils can make ** moisturizing and shiny.

Vegetable oil precautions.

To buy pre-packaged edible vegetable oil in regular supermarkets. Select the production date is close to the time of purchase and the expiration date.

products. When edible vegetable oil is in liquid form, choose one that is clear and transparent. When eating at home, it is advisable to choose a suitable small package of edible vegetable oil according to the number of people. The quality and safety of bulk edible vegetable oil are difficult to guarantee, and it is not recommended for consumers to buy it.

When stir-frying, the oil temperature should be avoided too high, which will not only lead to changes in the chemical structure of the oil itself, affecting the digestion and absorption of the human body, but also destroy the fat-soluble vitamins A, D and E in the oil, resulting in a decrease in nutritional value. If you really need to fry at high temperature, it is suitable to choose rapeseed oil.

A blended oil with a higher content. Families are advised to use steaming, boiling, stewing or blanching to minimise frying.

Edible oil and fat products are:Trans fatty acids

Trans fats, also known as trans fatty acids, are the abbreviation for a large group of fatty acids that contain trans double bonds. It mainly comes from two categories: one is natural, mainly found in beef and mutton and cow and goat milk.

Middle. Second, it is produced in the process of food processing, commonly found in vegetable shortening, margarine, etc.

Trans fatty acids are a general term for fatty acids that contain trans-unconjugated double bond structures, unsaturated rocks, and fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids.

World Health Organization.

It is suggested that the daily calories from trans fatty acids should not exceed 1% of the total calories of the food (roughly equivalent to 2 grams), and this target has been adopted in China to evaluate food filial piety.

Foods that contain more trans fatty acids should be minimized in the daily diet. Hydrogenated vegetable oil is included in the ingredient list.

Foods such as cocoa butter, margarine, margarine, and margarine should not be consumed excessively.

Let's start by correcting a common myth: hydrogenated vegetable oils are not the same as trans fats.

Some people often think on the Internet and in life that the main ingredient of hydrogenated oil (margarine, etc.) is trans fat, or simply trans fat. Not really.

Hydrogenated oils are oils and fats that are hydrotreated to become solid or semi-solid by hydrogenation to obtain saturated fats, while trans fats are unsaturated fats. Trans fatty acids are produced only when vegetable oils are not completely hydrogenated, and if they are completely hydrogenated, they are not trans fats but saturated fats.

According to the different degrees of hydrogenation, hydrogenated oils can be divided into two categories: partially hydrogenated oils and extremely hydrogenated oils.

Some hydrogenated oils have only undergone a limited degree of hydrotreating, and their trans fatty acid content is high, averaging around 20%.

Extremely hydrogenated oil is a completely hydrogenated oil, also known as hardened oil, in which the trans fatty acid content is very low, generally less than 1%, so the fully hydrogenated oil actually contains almost no trans fatty acids.

Hydrogenated oil is usually an intermediate product, is one of the components of special food oils and fats (frying oil, shortening, cocoa butter substitutes), and the proportion of special oils and fats does not exceed 10% overall, and more than 90% of the components of special oils and fats are palm oil, palm kernel oil, coconut oil, etc., and these natural vegetable oils almost do not contain trans fatty acids.

Food special oil is not equal to hydrogenated oil, whether to add hydrogenated oil in the formula of special oil, what kind of hydrogenated oil to add, and how much to add, depending on the use of the special oil, the content of trans fatty acids varies greatly.

In recent years, domestic manufacturers have reduced the trans fat content by improving the hydrogenation process or fractionation technology, including the introduction of transesterification process to replace the hydrogenation process. The transesterification process produces special fats and fats that contain almost no trans fatty acids.

Summary. Edible vegetable oil is not trans fatty acids, but trans fatty acids may exist in vegetable oil, edible vegetable oil is edible oil made from edible vegetable oil or plant **, such as soybean oil, rapeseed oil, peanut oil, sesame oil and so on.

Trans fatty acids are a general term for unsaturated fatty acids containing trans non-conjugated double bond structure, hydrogenated vegetable oil is the most important food for trans fatty acids**, and vegetable oils based on unsaturated fatty acids are hydrogenated and hardened under the action of catalysts such as pressure and nickel, and change from liquid unsaturated fatty acids to solid or semi-solid saturated fatty acids.

Is edible vegetable oil a trans fatty acid?

Edible vegetable oil is not trans fatty acids, but trans fatty acids may exist in vegetable oil, edible vegetable oil is edible oil made from edible vegetable oil or plant **, such as soybean oil, rapeseed oil, peanut oil, sesame oil and so on. Trans fatty acids are a general term for unsaturated fatty acids containing trans unconjugated double bond structure, hydrogenated vegetable oil is the most important food for trans fatty acids**, and vegetable Huizao oil based on unsaturated fatty acids is hydrogenated and hardened under the action of catalysts such as pressurization and nickel brother bihan, and changes from liquid unsaturated fatty acids to solid or semi-solid saturated fatty acids. Envy.

Canola oil is a blended oil made from three types of rapeseed: mustard greens, cabbage, and oil. They all belong to high canola, and in untreated rapeseed oil, erucic acid is as high. Such a high content will cause gastrointestinal discomfort, difficult digestion, poor absorption and utilization, and thus reduce the nutrition of the oil.

Long-term consumption of vegetable oil rich in erucic acid can easily cause thickening of blood vessel walls and myocardial fat deposition. Therefore, we try to choose vegetable oils with no more than 5% erucic acid. But when it comes to trans fatty acids, canola oil doesn't contain them.

Soybean oil is also one of the vegetable oils that we regularly consume. Soybean oil is an oil with unsaturated fatty acids as the main content, and its content can be as high as 85%, of which linolenic acid accounts for about 10% and linoleic acid accounts for about 500%. These substances are necessary for the growth, development and maintenance of normal physiological activities of our body, and regular consumption can effectively increase the excretion of cholesterol and bile acid.

Soybean oil also contains 25% monounsaturated limb fatty acids, which have the effect of lowering blood cholesterol. However, it does not contain trans fatty acids, so it can be eaten with confidence. In fact, many vegetable oils do not contain Lituanhe trans fatty acids, take peanut oil as an example.

Peanut oil contains a large number of nutrients that are unsaturated fatty acids, which can reduce serum cholesterol and glycerol esters, and effectively prevent and treat cardiovascular and cerebrovascular diseases. The various trace elements and nutrients contained in the mill can also help the body to enhance immunity.

All kinds of puffed foods, cakes, and biscuits are the "hardest hit areas" of trans fatty acids.
