Which are vegetable oils and what are vegetable oils

Now, as a new energy practitioner, I would like to tell you why new energy fuels can replace methanol and liquefied gas on the market?

1.The product is more durable and cheaper than methanol and liquefied gas, and the fuel cost used by customers is reduced in two directions (durability depends on the product, so the product is the core).

2.In addition, alcohol-based fuels have existed in the fuel market for more than ten years, and the market is in a saturated state.

3.There is also the control of methanol liquefied gas by the first department, and the current insertion of new energy can be described as an opportunity. (Don't tell me it's okay if you don't control it, you still do it secretly, breaking the law is violating).

Note: Alcohol-free fuel is not only called alcohol-free fuel if the flash point is greater than 60, the most important thing is whether the product can be put on the market after the legal conditions, like the cost of vegetable oil biodiesel made by many companies is too high, and it cannot be done at all.

So to sum up: a legal, safe, environmentally friendly and more economical product is bound to replace the current fuel market.

Vegetable oil is the oil extracted from plants, common: soybean oil, rapeseed oil, peanut oil, sunflower oil, olive oil, corn oil, coconut oil, walnut oil, grape seed oil and so on.

The seeds of plants are pressed, and the oil produced is vegetable oil, well, melon seed oil, corn oil, peanut oil, flaxseed oil, olive oil, all belong to vegetable oil.

Vegetable oil, as the name suggests, comes from the fruits, seeds, germs, etc. of plants, such as peanut oil, soybean oil, rapeseed oil, palm oil, castor oil, etc. It is a compound made from a combination of fatty acids and glycerol and is widely found in nature. Its main components are linear high-level fatty acids and glycerol-generated esters, including unsaturated fatty acids, palmitic acid, stearic acid, etc.

Edible vegetable oils contain more unsaturated fatty acids than animal oils, making them more nutritious than animal oils. Edible vegetable oil also contains vitamin E, vitamin K, and minerals such as calcium, iron, phosphorus, and potassium.

Vegetable oils can be divided into two categories: oils and fats according to their properties. Usually the liquid at room temperature is called oil; Those that are solid and semi-solid at room temperature are called lipids. According to the use, it is divided into two categories: edible vegetable oil and industrial vegetable oil.

At present, there are many types of household edible vegetable oil, such as peanut oil, rapeseed oil, soybean oil, cottonseed oil, sesame oil, sunflower oil, etc. Industrial vegetable oils: mainly used as raw materials for industrial products such as soap, paint, ink, rubber, tanning, textiles, candles, lubricating oils, synthetic resins, cosmetics and pharmaceuticals.

When people buy edible vegetable oil, they should initially identify the quality of the oil from the aspects of color, transparency, and smell of the oil. Generally speaking, high-quality oils are light in color and low-quality in color (except sesame oil); The vegetable oil has high transparency, less water and impurities, no stratification, no sour odor and peculiar smell.

Vegetable oil is made from plant fruits and other extracted oils, including rapeseed oil, peanut oil, tea seed oil, soybean oil, sesame oil, olive oil, sunflower oil, sugar oil, etc. Non-edible oils include castor oil, tung oil, etc.

What is Vegetable Oil? Vegetable oil is a chemical substance formed by the reaction of higher fatty acids and glycerol. Widely distributed in nature, it is an oil obtained from the fruit seed germ of plants, such as peanut oil, soybean oil, and flax oil.

The main components of vegetable oils such as KPMG oil and rapeseed oil are linear high-chain fatty acids and glycerol-generated esters. Fatty acid. In addition to palmitic acid, stearic acid and oleic acid, it also contains a variety of unsaturated acids, such as erucic acid.

Vegetable oils such as ricin mainly contain minerals such as vitamins, easy K, calcium, iron, phosphorus, potassium, etc. Fatty acids and other fatty acids in vegetable oils can make ** moisturizing and shiny.

Vegetable oil is widely distributed in nature and is obtained from the fruit, seed, and germ of plants.

There are three main uses for vegetable oils. The first is edible vegetable oils and fats. Edible vegetable oils and fats are important non-staple foods for human beings, mainly used in cooking, pastries, canned food, etc. This is followed by vegetable oils and fats for industrial use. Finally, vegetable oils and fats are one of the important commodities in the international market.

The main components of vegetable oil are linear high-grade fatty acids and glycerol-generated esters, which contain a variety of unsaturated acids in addition to palmitic acid, stearic acid and oleic acid, such as erucic acid, tung oleic acid, ricinoleic acid, etc.

Vegetable oil mainly contains minerals such as vitamin E, K, calcium, iron, phosphorus, potassium, and fatty acids. The fatty acids in vegetable oils can make ** moisturizing and shiny.

Vegetable oil can be divided into herbal vegetable oil and wood vegetable oil. Among them, herbal vegetable oils include: hemp oil, soybean oil, corn oil, peanut oil, rapeseed oil, sesame oil, sunflower oil, cottonseed oil, sesame oil, flax oil, etc.; Woody vegetable oils are:

Camellia oleifera seed oil, peony seed oil, palm oil, walnut oil, coconut oil, olive oil, etc.

Having said all that, what exactly is vegetable oil?

Vegetable oils are derived from plants, real oils, real fatty oils. The main ingredient is triglycerides formed by the combination of fatty acids + glycerol. The liquid state at room temperature is called oil, and the solid state at room temperature is called fat, collectively referred to as grease.

Most of the vegetable oils are extracted from seeds, such as soybeans, sunflowers, peanuts, rapeseeds, etc., until the twentieth century, when humans learned how to extract vegetable oils, and we simply did not have the technology to extract them.

The ways in which vegetable oil is made can be divided into two main categories.

1. Leaching, the leaching method uses chemical solvents, such as light gasoline, which will have a certain residue in the final finished product, which is within the allowable range of the national standard.

2. Squeezing (hot and cold pressing) The squeezing method is to squeeze out the lipid components in the raw materials through the method of logistics pressing, and there is no need to add chemical solvents in the whole process. This process produces a lower yield of edible oil than leaching, **.

Second, the types of edible oils and fats.

In our daily diet, we will stir-fry vegetables every day, we mostly use peanut oil when stir-frying, soybean oil is more edible in the northeast, and rapeseed oil is more in the south.

Many people can't make up their minds about what oil should be used for stir-frying, and some people will use several oils to stir-fry alternately, such as peanut oil, olive oil, and sunflower oil, thinking that this can better ensure nutrition.

Sesame oil is usually used in cold dishes in the daily diet, and it is eaten in relatively small quantities and has little effect on human health.

Animal fat, lard, butter, sheep fat, now eat less, more than 40 years ago in the lack of vegetable oil, every household will use lard to fry vegetables.

To discuss which oil is good to eat, first of all, it is necessary to clarify why you should eat vegetable oil.

3. Why should you eat vegetable oil in your daily diet?

There are seven major nutrients in the food we eat every day, namely: protein, fat, carbohydrates, vitamins, minerals, dietary fiber and water, and fat ranks second.

Why do we consume vegetable oil?

1. Vegetable oil can provide us with heat.

2. Vegetable oil can increase satiety for us.

3. One of the most important functions is to provide us with essential fatty acids.

4. Essential fatty acids.

Essential fatty acids are fatty acids that cannot be synthesized by the human body and must be provided through food, and this fatty acid is mainly polyunsaturated fatty acids.

Essential fatty acids have important physiological functions, are important components of phospholipid synthesis, can regulate blood lipid metabolism, have the effect of reducing total cholesterol and triglycerides, and increase the level of high-density lipoprotein. If the deficiency is deficient, it can cause a rash that is damaged, and it can also cause diseases of the liver, kidneys, nerves, and visual systems.

Vegetable oil is an important oil resource in China, and it can often be used in the process of cooking dishes. According to the relevant statistics, a person has to eat tons of edible oil in his life, and good vegetable oil can be said to be of great significance to human health. In addition, vegetable oils are also divided into types, so it is necessary to have a good understanding of vegetable oils.

1. What is vegetable oil?

Vegetable oil is a refined oil obtained after a series of processing of oil-rich plant kernels, its biggest feature is that it is rich in unsaturated fatty acids, which can supplement oil and improve malnutrition, poor physical strength and other problems after eating, and the fatty acids of vegetable oil have the effect of moisturizing, in addition to unsaturated fatty acids in regulating human blood lipid levels and cleaning up blood clots.

2. What are the classifications of vegetable oil?

1. Soybean oil.

Soybean oil is the most widely used and consumed in China. Soybean oil is mainly based on linoleic acid, an essential fatty acid (50-60%), and the content of linolenic acid is 5-9%, which is the "star fatty acid" that is currently recommended for consumption. Moreover, soybean oil has many unique micronutrients, such as phospholipids, carotene, VE, sterols, etc., and the nutritional value is extremely high.

2. Peanut oil.

Peanut oil is a healthy choice for the elderly. Peanut oil contains more than 80% unsaturated fatty acids (including oleic acid, linoleic acid. The fatty acid content of peanut oil is second only to olive oil and tea seed oil, and higher than soybean oil and sunflower oil.

Peanut oil has good oxidative stability and is suitable for general stir-frying and frying.

3. Rapeseed oil.

Rapeseed oil is also called camellia oil, and the fatty acid ratio of camellia seed oil is close to that of olive oil, which is an oil with relatively high nutritional value. In addition, camellia seed oil has a long shelf life, is easier to preserve, and has good heat resistance, in addition to being used for general stir-frying, it can also be used as frying oil.

4. Sesame oil.

Sesame oil, also known as sesame oil, is very suitable as an oil for cold dishes. The main fatty acid composition of sesame oil is similar to that of peanut oil and cottonseed oil, which belongs to the balanced type, that is, the content of saturated fatty acids is about 20%, and oleic acid and linoleic acid are basically equivalent among unsaturated fatty acids. In addition, sesame oil is rich in vitamin E and natural antioxidants such as sesamol, sesamol, and sesamin, which have certain health benefits.

In general, vegetable oil is an indispensable material in people's lives, and it is important to know that 70% of the total amount of fatty acids necessary for the human body is obtained from the vegetable oil we consume daily. Usually vegetable oil is best eaten together, which is beneficial to human health.

Animal oil, that is, animal fat, is animal fat, animal oil for human consumption is generally ** pigs, cattle, fish, etc., can be used to process food, so that the food has the flavor of meat. When paired with a vegetarian diet with a large amount of oil, such as eggplant and radish, it will have an appetizing sweet taste and the flavor of meat, a lot of calories and nutrients that vegetable oil does not have, and promote the body's nutrient absorption of ingredients, especially vitamins.

Animal oil is represented by lard, which contains more saturated fatty acids and cholesterol. Excessive consumption can easily cause hypertension, arteriosclerosis, coronary heart disease, hyperlipidemia and cerebrovascular accidents, which is not good for the human body. However, animal oil has a fragrant taste and has the effect of promoting the absorption of fat-soluble vitamins A, D, E, K, etc.

In addition, cholesterol in animal oil is also an important component of human tissue cells, and is an important raw material for the synthesis of bile and certain hormones.

Compared with the general vegetable oil, the oil of animal oil has an irreplaceable special fragrance and can increase people's appetite. Especially when paired with radish, vermicelli and soy products, it can obtain a delicious taste that is difficult to achieve with other seasonings; Animal oil contains a variety of fatty acids, and the content of saturated fatty acids and unsaturated fatty acids is comparable, almost equal, with certain nutrients, and can provide extremely high calories. The digestion and absorption rate of cream in the human body is higher than that before the hidden, up to more than 95%, it is a seasoning with high content of vitamin A and vitamin D, and the proportion of fat contained in it is less than that of butter, which is more suitable for people and children who lack vitamin A.

There are many types of vegetable oil, common ones are peanut oil, olive oil, rapeseed oil, corn oil, sesame oil, soybean oil, etc.
