Deep-fried food antioxidant TBHQ
Therefore, the necessity of adding antioxidant tert butyl hydroquinone (TBHQ) to baked goods is evident and sufficient,leading to food poisoning. Adding antioxidant TBHO is a simple, economical, and ideal method to prevent and slow down the loss of nutrients and the generation of odors caused by food oxidation.
At high temperatures, a series of complex chemical reactions such as oxidation, decomposition, polymerization, and hydrolysis are prone to occur, resulting in a rapid increase in the acid value, peroxide value, and carbon base value of roasted foods. In the later stage of storage and sales, unpleasant odors are easily produced.
The main mechanism of TBHQ is to provide hydrogen to the free radicals R or RO0 in oils and fats, which can form stable dimers and become relatively stable substances.Temperature is the most important factor affecting oil oxidation, similar to general chemical reactions. As the temperature increases, the automatic oxidation rate of oil in the food increases. For every 10C increase in temperature.
In addition, essential fatty acids such as linoleic acid and linolenic acid in oil are also damaged, reducing the nutritional function of the product. In severe cases, harmful substances such as oxides, peroxides, and decomposition products such as epoxypropylaldehyde can be produced, leading to food poisoning. Adding antioxidant TBHO is a simple, economical, and ideal method to prevent and slow down the loss of nutrients and the generation of odors caused by food oxidation.
Therefore, adding an appropriate amount of antioxidant tert butyl hydroquinone (TBHQ) according to the characteristics of pastry food during the processing is necessary and effective in slowing down the oxidation of oil and fat during the production process, preventing the loss of nutrients and stabilizing color, maintaining the good flavor of the product, and extending the shelf life of the product. Therefore, the necessity of adding antioxidant tert butyl hydroquinone (TBHQ) to baked goods is evident and sufficient.
