Why should food additives be added to edible oil

Edible oil is prone to oxidation rancidity, which needs to be blocked by food additives.

In addition to providing heat energy and essential fatty acids, edible oil can also increase the digestion and absorption of fat-soluble vitamins and improve the palatability and fullness of food. The energy provided by edible oil accounts for about 20%-35% of the total dietary energy, in which the amount and type of fat will have an impact on health.

A large number of epidemiological investigations show that coronary heart disease is positively correlated with dietary intake of saturated fat and cholesterol (Philippines food Ingredient supplier) , that is, the presence of polyunsaturated fatty acids in edible oil is beneficial to human health, and many polyunsaturated fatty acids are essential fatty acids for the human body. the human body cannot synthesize itself and must be ingested through food.

However, it can not be ignored that polyunsaturated fatty acids are very unstable and prone to oxidation (Philippines food flavour wholesale) , which not only causes the deterioration of the quality of oils and makes them unfit for consumption (Philippines food flavour supplier) , but also produces ingredients harmful to health. and the intake of large amounts of polyunsaturated fatty acids will also accelerate the oxidative denaturation of plasma lipoproteins and induce atherosclerosis.

Edible oil oxidation conditions are oxygen, light, metal ions, high temperature will also accelerate the oxidation process (Philippines food flavour wholesale) .

In order to delay the oxidation process of edible oil (Philippines food flavour supplier) , appropriate amount of oil-soluble antioxidants (Philippines food Ingredient supplier) , such as butyl hydroxyanisole (BHA), dibutylhydroxytoluene (BHT) and other food additives, should be added in the later stage of oil processing, and the metal elements in citric acid and its salts chelating oil should also be added to further reduce the rate of oxidation. Therefore, food additive citric acid and its salt should be added. It is also known as the synergist of oil antioxidants.

In order to reduce the oxidation of edible oil, it is best to place the edible oil in a cool, dry place away from light (Philippines food flavour wholesale) .
