Harm caused by edible oil rancidity

Edible oil rancidity body will bring big harm. For example, the loss of a large number of unsaturated fatty acids; many intermediate products of oxidation - into the body of free radicals damage the body's tissues and cells, thereby causing chronic diseases and aging effects, and even cancer; long-term consumption of rancidity of fats, can lead to a lack of essential fatty acid and a series of symptoms; when processing rancid cooking oil, other foods can also unstable to oxygen vitamin destruction.

Eat peanuts and peanut oil can lose weight without rebound

Nutrition experts found that high-quality peanut oil and other peanut products has a nutrient called folic acid, it contains a lot of monounsaturated fatty acids, can increase the heat dissipation, burning harmful cholesterol, reduce high blood lipids.

Therefore, in recent years, the United States, Britain, Australia and other countries nutrition experts emphasize the peanut and peanut products can effectively help people control weight and prevent obesity.

I heard some people to lose weight, eating simply hold oil, this is really more effective? New research of foreign experts rejected this approach. In fact, the proper selection of edible oil varieties, often eat peanuts and other nuts, nuts and other edible peanut oil, not only will not make people fat, but also so that people can get the full nutrition in the diet, but do not worry about gaining weight, so weight loss becomes get easier.

Camellia oil can replace olive oil

Camellia oil and tea seed oil, derived from the seeds of oil tea tree. In Hunan, Jiangxi and other places of hills, mountains and plains are oil tea tree, camellia oil has almost become a beautiful symbol SOUTH local culture.

Advantages: camellia oil unsaturated fatty acids up to 85% to 97%, higher than any oil, and oleic acid (a kind of mono-unsaturated fatty acids, help to reduce blood "bad cholesterol", raised one of the "good cholesterol "beneficial for controlling blood lipid) content of about 80%, even higher than olive oil. Camellia oil in nutritional value, therapeutic function not inferior to olive oil, and the price is cheaper, can be considered inexpensive, it is also known as the "Oriental olive oil." Camellia oil have good heat resistance.

disadvantages: camellia oil polyunsaturated fatty acid content is relatively low.

Recommendations: Currently, some small oil pressing workshop take indigenous oil hot press method, there may be impurities, nutrition loss of large, easy to mold and other issues, we recommended to buy big brand camellia oil. Camellia oil for everyday cooking, can be used as salad. Camellia oil for soybean oil, corn oil containing polyunsaturated fatty acids with fat.

Linseed oil is best used for salad

Linseed oil, from flax seed extracting, is an ancient vegetable oil.

Advantages: linseed oil have essential fatty acids linolenic acid content of more than 50 percent, far higher than fish oil 5% and 6% to 12% walnuts, pine nuts. Linolenic acid is an omega-3 fatty acids in the human body can be converted to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), they can reach the brain and retina cell membranes, depending on the rod cell membrane, biological electrical impulses in the brain directional transfer rate, is conducive to thinking, and larger memory capacity. So, linolenic acid with enhanced intelligence, memory, logical thinking ability and function to protect eyesight. Linolenic acid can also adjust the dyslipidemia, inhibit platelet aggregation, prevent thrombosis, and inhibit cancer cell generation and transfer.

Disadvantages: easily oxidized and polymerization.

Recommendations: children, pregnant women, the elderly, etc., may be appropriately selected linseed oil, good for mental development, slow memory loss. Linseed oil unsaturated degree is too high, you have to eat after opening as soon as possible, it is best used for salad.

Can corn oil color changed be eat?

Measure the oil is safe or not, color is not a reliable indicator.

Edible oil color reversion occurs, the best thing to detect indicators are peroxide value of oil, to see whether excessive, if only due to the normal oxidation.

Only by eyes can not determine whether the deterioration of oil.

If necessary, you can find a professional testing organization for testing and then make decisions.

For ordinary consumers, they can smell to assist judgment.

If there is a rancid smell, even slightly, it should not continue to use, peroxide will cause harm to body.

Children should be chosen to replace the use of a variety of edible oils

Born within six months, the baby has not yet begun to add a food supplement, obviating the need for oil. 6 months to 1 year old, you can add a little oil at the time of making baby food supplement. For example, in a variety of porridge, noodles or small, a few drops of it.

In 1 year to 3 years old baby, all the food baby can eat basically, advice you can give a child a little fried vegetables and meat, eat the total oil is 20-25 grams per day. Aged 3 to 6 years old, can be increased to 25-30 grams per day.

In addition, the first condition of the healthy growth of the baby is comprehensive nutrition. Therefore, cooking food for children to choose from a variety of edible oil replacement use. So baby can get comprehensive fatty acids.

How to choose edible oil?

For the food industry, further development is to adjust the structure, but also from Europe experience, they have oils for hypertension and diabetes people. Then the future may be refined, which may be the future efforts.

From production suppliers concerned, then, to take into account the structural problems, what do you give consumers. Diversity is the prerequisite and basis balance.

Another is to select a small package, not a bottle for a very long time, as soon as possible to use off, thus reducing the adverse material. Of course, from the industry in terms of blend oil is to be considered.

Sesame oil are divided into ground and machine-processed sesame seed oil

Ground sesame seed oil, also known as small grinding sesame oil. Sesame seeds as raw material, water processing system, with a strong distinctive flavor, it is good for flavoring oils. Water processing system in our country has more than 400 years of history. Sesame oil is mainly used adorned seasoning, is also the main characteristics of food materials some traditional pastries. In addition to domestic sales, there is a certain amount per year sold to Hong Kong and Macao and Southeast Asian countries.

Machine-processed sesame seed oil, sesame seeds as raw material, through a specific process, with machine-pressed to make, has a significant sesame oil flavor. According to national standards, it is divided into one and two grade.

Identification of edible oil by viscosity

Vegetable oil viscosity refers to the degree of viscous oil. Under less carbon atoms with a high degree of unsaturated fatty acids in the general situation in the oil group, the viscosity can be seen a little lower, but not much difference, such as the presence of an oxygen-containing acid oils, epoxy conjugate acid and oxidation polymer can increase the viscosity. Because of high temperature heating, oil oxidation polymerization, oil viscosity gradually increased, the level can be used as a measure index of the degree of deterioration of the cooking oil.

Identification of edible oil by smell and taste

According to its smell and taste, you can identify raw materials, methods, and refining degree; can determine the length of time the oil is stored, and whether the oxidative deterioration and rancidity. Generally clean, new oil processing, sniffing it has its normal peculiar smell and taste. But the refined cooking oil, because after vacuum deodorization treatment, the unique smell is removed, so the fat rendered fresh smell.

Identification of grease smell, usually at a temperature of 20 ℃, the grease dripping onto the palm, friction heat can sniff out odors, oxidation and rancidity of fats, obviously the rancid smell; generally directly with the tongue licking taste, oxidation and rancidity of fats with a spicy taste, rancid grease with serious odor.

Large bottles of cooking oil is easily oxidized metamorphic

Cooking oil should not be in long-term storage, particularly vulnerable arising from oxidative deterioration because of light, heat or seal leakage and other reasons, affecting human health.

Edible oil bottle or pail shelf life base on the mouth tightly closed containers not leak as a precondition, the shelf life greater than one year, are generally required to add antioxidants.

Cooking oil is every day to the entrance you'll feel, oxidation can lead to excessive fat sour, rancid grease can lead to human liver enlargement and stunted growth, accelerated aging; peroxide value seriously overweight, can cause diarrhea and other gastrointestinal side effects, may also induce cardiovascular, cancer and other diseases.

Do not eat the same kind of edible oil long-term

In addition to cooking oil per person per day not more than 25 grams, but not long-term consumption of an oil, usually an appropriate mix of some high-end edible oils, such as walnut oil, safflower oil, camellia oil or olive oil.

Specifically: eat 1.5kg peanut oil in this period, should be compatible with 0.5 kg walnut oil or safflower oil, and occasionally replace with high-end food and cooking oil can be effective in preventing cardiovascular disease.

For already suffering from coronary heart disease, cardiovascular disease, stroke and diabetes population, should use the high-end cooking oil as the main choice of oil daily.

It recommends the promotion of plastic bottles of cooking oil

Experts pointed out that all kinds of domestic edible oil, including domestic high-grade tea oil, safflower seed oil, plastic bottles for more. The reason why foreign general to use 500 ml small size of glass bottles of olive oil, is not to highlight its worth, but on everyday cooking habits, poured drops of olive oil is generally used on the table dipped, thick slender square glass bottle focus is safe and practical.

Experts suggest that, in view of waste recycling channels now almost rarely recycle glass bottles, glass waste generated in life are difficult to handle, so the switch to plastic bottles of various types of imported edible oil packaging undoubtedly is more practical significance. In addition, since such lecythus burst after the accident verified container quality is difficult to identify, difficult to consumer rights, in order to ensure safety and reduce unnecessary losses, when the current cooking oil if still use glass bottles, away from heat sources .

Do not worry suspended solids of peanut oil

Any substance has a fixed physical and chemical characteristics. A substance by the temperature of the solid becomes liquid when called melting point, when the liquid into a solid called the freezing point, the two are the same value. Cooking oil is no exception, such as soybean oil freezing point -18-15 degrees Celsius, the freezing point of rapeseed oil -12-10 degrees Celsius, the freezing point of sunflower oil is -18-16 degrees Celsius, while peanut oil freezing point higher at 12 -15 degrees Celsius. Peanut oil solidification occurs at low temperatures, the semi-hardened phenomenon is its inherent characteristics.

Experts suggest that if consumers buy high-quality peanut oil, appear solid or floc is normal phenomenon, can be safe to eat. Consumers buy peanut oil, you can use a small glass install some peanut oil in 10 degrees Celsius water, to see if it will not appear flocculent suspended matter, if not, it means that it is not pure peanut oil.

Adverse effects on human health by eating too much animal oil

First, increase the risk of cardiovascular and cerebrovascular disease.
Second, the brain damage, including closer relations with dementia.
Third, with certain types of cancer, such as colorectal cancer, the incidence of breast cancer related.
Fourth, it can reduce the response to insulin, so that may increase the risk of diabetes.
Fifth, it can promote the formation of oxygen free radicals, speed up the body to produce oxygen free radicals, and is caused by too much oxygen free radicals many diseases such as cardiovascular disease, an important reason for some cancers, premature aging, decreased immunity.
So, rich in saturated fats and meat animal oil, you must limit control. Experts believe that the daily calories from saturated fat should be less than 10% of total body heat.

Instruction of olive oil and tea oil

Olive oil

Its advantage is that monounsaturated fatty acid content of up to 70%. Research confirmed that while polyunsaturated fatty acids can reduce cholesterol, but it is easier to cause oxidative damage in the body, excessive consumption of the same is not conducive to good health; less susceptible to oxidation of unsaturated fatty acids, but easily lead to increased blood lipids. Monounsaturated fatty acids to avoid the adverse consequences of the two, and has good heat resistance. Olive oil can be used to cooking, can also be used cold, the drawback is vitamin E is relatively small.

Tea oil

More than 90% unsaturated fatty acids, monounsaturated fatty acids as much as 73%, a certain amount of vitamin E, useful in the prevention of cardiovascular disease. It is resistant to storage, high temperature, suitable for use as a cooking oil and frying oil.

How to eat oil in a scientific way?

Grease is one of the six elements of the human body, essential substances of the body's growth and development and life-sustaining activities, and its main function is to provide the energy needed to dissolve fat-soluble vitamins A, D, E, K. More importantly, it provides essential fatty acids.

From the nutritional point of view, the adoption of food to get fat needed by the body is more healthy than eating edible oil.

In daily life, mainly oil is for cooking food. Oil played a role in the conduction of heat in cooking, it is possible to improve the taste of dishes. Therefore, no intake of edible oil will not have much impact on health. On the contrary, many people tend to excessive intake of fat, which brings the health risks.

Because the human body needs only 25 to 30 grams of fat per day for the standard. In addition to culinary delights, in fact, we usually eat cake, bread, cookies and other foods which are also very rich in oil, an inattentive, body fat intake may be exceeded.
